The Impact of Female Director Background on the ESG Performance of Chinese Technology Firms: A Moderating Effect Based on Risk Appetite

As global focus persists on gender variety and corporate social responsibility, the participation and influence of women in corporate governance, particularly their effect on the environmental, social, and governance (ESG) performance of corporations, have garnered extensive scrutiny. Given the significant differences between China and the West in terms of institutions and culture, it is highly valuable to explore the unique relationship between gender diversity and ESG performance in the Chinese context, especially in the high-risk and fast-growing technology industry. This study explores the impact of female director background on ESG performance and the moderating effect of risk appetite. The findings suggest that the proportion of female directors has a significant positive impact on the ESG performance of Chinese technology companies. Furthermore, the corporate risk appetite has a positive moderating effect on the relationship between the proportion of female directors and ESG performance. Female directors with higher education levels, financial professional background, and long-term tenure can more effectively promote the company’s ESG performance. This study enhances the theoretical framework of corporate governance and ESG studies while also offering innovative guidance for firms to enhance their ESG scores and develop effective risk management strategies.

The invisible connection of mothers' BMI, emotional appetite, and food choices with childhood obesity.

This study examined the effects of mothers' body mass index (BMI), emotional appetite, and food choices on children's growth curves and adiposity. Data was collected from 492 mothers. The demographic characteristics and anthropometric measurements were obtained using a questionnaire. The mothers' food choices and emotional appetites were assessed using scales. BMI for age Z score and tripoderal index (TMI) were used in the evaluation of children's anthropometric measurements and adiposity. The mean age of mothers' was 39.10 ± 0.26 and BMI was 25.08 ± 0.21. Among the mothers, 54.5% were classified as normal, 28.4% as pre-obese, and 14.7% as obese. Among the children, 31.5% were overweight or obese. There was a strong positive correlation between the mean BMI of the mothers and the mean TMI and BMI of the children (p < 0.001). The "convenience" food choice factor of mothers had negative correlation with childiren's BMI for age (p < 0.005). This study emphasizes the invisible connection between mothers' emotional appetite and food choices and children's BMI and TMI and highlights the importance of paying attention to mothers' eating habits for children's health outcomes. These findings will be informative in the formulation of future health policies. This research revealed the relationship between mothers' food choices and emotional appetites, and their children's growth curves and adiposity. The study proposes the Triponderal Index as an alternative approach to evaluating growth, introducing a novel perspective in growth monitoring. By highlighting the impact of mothers' emotional appetites and food choices on children's dietary habits and weight status, the research emphasizes the significance of family eating habits. The findings support the promotion of healthy dietary practices within families as a crucial measure in preventing and managing childhood obesity, conveying a significant message to parents and healthcare professionals for a healthier future.

Optimal multi-period source-sink matching in carbon capture, utilization, and storage (CCUS) systems under neutrosophic environment

Carbon capture, utilization, and storage (CCUS) is an important technology for mitigating the effect of climate change. It involves the capture of CO2 from a point source, transport it through pipelines and store it in geological reservoirs for permanent storage. CCUS enables the use of fossil fuel-based power plant sources that produce a steady amount of energy and the reduction of CO2 emissions from these sources simultaneously. While CO2 sources are easy to characterize, the storage parameters of geological reservoirs are more difficult to measure, thus, estimates are provided and used for planning large-scale CCUS systems. CO2 utilization can provide a means to delay CO2 emissions by converting it highly valuable products, however, its sequestration potential is highly uncertain. A systematic mathematical approach is needed to effectively plan CCUS systems considering the risks associated with the estimates in the characteristics of the geological reservoir and the sequestration benefits from CO2 utilization. In this study, an optimization model is developed for planning multi-period CCUS systems under neutrosophic environment. The model considers managing storage risk by maximizing satisfaction from minimizing risks, minimizing dissatisfaction from consequences brought by these risks, and minimizing indeterminacy from inaccuracy of storage characteristics estimates. For utilization, the model considers the satisfaction for CO2 utilization benefits, dissatisfaction for opportunity losses, and indeterminacy in sequestration potential. Two case studies are used to illustrate the model where a sensitivity analysis is performed to illustrate the effect of the different risk appetite on the optimal solution. These cases studies reveal important insights on scheduling operations between CO2 sources and sinks and the allocation of captured CO2 for storage and utilization. The model can be used to develop policies for considering the risks associated with these uncertainties and how it will be managed.

The Impact of Corporate ESG Performance on Environmental Investment

As a standard for measuring corporate sustainability and long-term value growth investment, corporate ESG performance is of great significance for evaluating corporate sustainability, guiding investment decisions and promoting corporate improvement. Based on the sample of A-share listed companies in Shanghai and Shenzhen that have obtained SynTao Green Finance’s ESG rating from 2011 to 2021, this paper empirically examines the role of corporate ESG performance on green investment based on the theory of “stakeholders” and the theory of “sustainable development”. The results show that: (1) good ESG performance can significantly improve the level of environmental investment, and this conclusion is still valid under a series of robustness tests; (2) The mechanism test shows that good ESG performance can expand the scale of enterprises and indirectly promote corporate green investment; (3) The intermediary mechanism test shows that there is a partial mediating effect of managerial risk appetite (Mrip) on ESG performance in environmental investment. In the new stage of accelerating the green transformation of China’s industry, Chinese enterprises urgently need to improve the green financial system, accelerate the process of green transformation, and help achieve the goals of “carbon peak” and “carbon neutrality”.

Intestinal and Renal Adaptations to Changes of Dietary Phosphate Concentrations in Rat.

We have studied the role of the intestine, kidney, and several hormones when adapting to changes in dietary P concentration. Normal and parathyroidectomized (PTX) rats were fed pH-matched diets containing 0.1%, 0.6%, and 1.2% P concentrations. 32Pi uptake was determined in the jejunum and kidney cortex brush border membrane vesicles. Several hormone and ion concentrations were determined in the blood and urine of rats. Both jejunum and kidney cortex Pi transport was regulated with 5 d of chronic feeding of P diets in normal rats. Acute adaptation was determined by switching foods on day 6, which was only clearly observed in the kidney cortex of normal rats, with more statistical variability in the jejunum. However, no paradoxical increase of Pi uptake in the jejunum was reproduced after the acute switch to the 1.2% P diet. Pi uptake in the jejunum was parathyroid hormone (PTH)-independent, but in the kidney, the chronic adaptation was reduced, and no acute dietary adaptations were observed. The NaPi2a protein was more abundant in the PTX than the sham kidneys, but contrary to the modest or absent changes in Pi uptake adaptation, the transporter was similarly regulated by dietary P, as in the sham rats. PTH and fibroblast growth factor 23 (FGF23) were the only hormones regulated by all diet changes, even in fasting animals, which exhibited regulated Pi transport despite similar phosphatemia. Evidence of Pi appetite effects was also observed. In brief, our results show new characteristics of Pi adaptations, including a lack of correlation between Pi transport, NaPi2a expression, and PTH/FGF23 concentrations.

Associations between the gut microbiome and metabolic, inflammatory, and appetitive effects of sleeve gastrectomy.

The complex and multifactorial etiology of obesity creates challenges for its effective long-term management. Increasingly, the gut microbiome is reported to play a key role in the maintenance of host health and wellbeing, with its dysregulation associated with chronic diseases such as obesity. The gut microbiome is hypothesized to contribute to obesity development and pathogenesis via several pathways involving food digestion, energy harvest and storage, production of metabolites influencing satiety, maintenance of gut barrier integrity, and bile acid metabolism. Moreover, the gut microbiome likely contributes to the metabolic, inflammatory, and satiety benefits and sustained weight-loss effects following bariatric procedures such as sleeve gastrectomy. While the field of gut microbiome research in relation to obesity and sleeve gastrectomy outcomes is largely in its infancy, the gut microbiome nonetheless holds great potential for understanding some of the mechanisms behind sleeve gastrectomy outcomes as well as for optimizing post-surgery benefits. This review will explore the current literature within the field as well as discuss the current limitations, including the small sample size, variability in methodological approaches, and lack of associative data, which need to be addressed in future studies.

Natural Appetite Control: Consumer Perception of Food-Based Appetite Regulating Aromas

According to the WHO, the number of overweight people (BMI ≥ 25) and obese people (BMI ≥ 30) is constantly growing. On the other hand, the number of elderly people (≥60 years old) in 2020 reached 1.4 billion worldwide. Both mentioned groups demonstrate their individual and characteristic appetite disorders. In light of the side effects of appetite stimulating drugs, which interfere with diabetics, hypertension and thrombosis medicines or diet supplements with doubtful effectiveness in reducing appetite, new and natural alternatives are highly demanded. Therefore, the present study focusses on the search for natural food aromas, which may have potential for appetite regulation. A survey was carried out among consumers with excess body weight (BMI ≥ 25) and the elderly (≥60 years old). Food products and meals pointed out by the survey participants were subjected to volatile analysis by HS-SPME Arrow followed by GC-MS. As a result, a group of volatiles and their odor characteristic were determined for appetite stimulation or reduction, which may suggest that the actual composition of food aroma is more significant than the character of the aroma. Those results may be a basis for designing appetite regulating agents, in which the mechanism of action will be based only on olfaction activity.

The Role of Loan-Related Risk Appetite in the Relationship between Financial Risk Considerations and MSME Growth Decision: A Mediation Analysis

While many studies have focused on assessing performance, studies that pivot on growth itself are limited. To contribute in this area, this study used the Stimulus-Organism-Response (SOR) Model as its foundation in order to explore how inflation and access to finance affected loan-related risk appetite, also known as their willingness to bear either debt-related or opportunity-related risks arising from loan acceptance or avoidance, respectively. Subsequently, the mediating effect of loan-related risk appetite between inflation and access to finance and growth decision was also investigated. The analysis of links between variables under scrutiny was premised on the utilization of partial least squares-structural equation modeling (PLS-SEM), with the data resulting from a purposive sampling method comprising 80 respondents who are owners and/or managers of their MSME business operating for at least two (2) years. The findings present that access to finance, as well as loan-related risk appetite, has direct links to growth decision. Access to finance was also found to have direct effects to loan-related risk appetite. On the other hand, it was found that loan-related risk appetite functions as a partial mediator between access to finance and growth decision. Contrarily, the aforementioned circumstances cannot be observed for inflation.

Risk appetite and option prices: Evidence from the Chinese SSE50 options market

This paper studies the relationship between risk appetite and the shape of the implied volatility function for SSE 50ETF options, and examines whether the effects of risk appetite differ on that of call and put options. We propose a new measure of risk appetite using high-frequency data in the stock market. Empirical results show that risk appetite has a significant impact on the level and slope of the implied volatility function, with significant differences between call and put options. In addition, we also find that risk appetite has an obvious asymmetric impact on option prices under the leverage effect.

Chili pepper preference development and its impact on dietary intake: A narrative review.

A preference for chili pepper can be an acquired taste. The contrast between a chili lover and a hater illustrates the complexities involved in forming an appreciation for food that evokes a fiery pain sensation. This narrative review aims to understand the factors behind chili pepper preference formation across the life course and how individual chili pepper preferences can impact eating behaviors and dietary intake. This review was conducted using three databases, yielding 38 included articles. Results suggest five determinants of chili pepper preferences: culture, exposure, gender, genetics, and personality. Collective findings indicate that the strongest influences on preference acquisition include the individual environment from childhood to adulthood and repeated exposure to spicy flavors. With frequent exposure to spicy food, the perceived burn becomes less intense. Culture also influences exposure to chili peppers, with the highest consumption patterns seen within Mexico and some Asia countries. Additionally, males reported having a stronger preference for spicy foods than females. Twin studies illustrated that genetics influenced spicy taste preferences, underscoring the complexity of developing individual taste preferences. As for the impact of capsaicin-containing food on individual eating behaviors and dietary behaviors, appetite effects depend on the dose of capsaicin consumed, but three studies found a change in sensory desires for sweet and fatty foods after finishing a capsaicin-containing dish. Inconsistent results were reported for chili pepper's effects on hunger and satiety after consumption, but changes in specific food desires were observed. The impact of chili pepper on appetite and calories consumed was inconsistent, but the greater amount of capsaicin ingested, the greater the effect. Capsaicin's potential to be used for weight control needs to be further reviewed. In conclusion, evidence suggests that chili pepper preferences may be linked to innate and environmental aspects such as an individual's culture, gender, and genetics. Extrinsic factors like repeated exposure may increase the liking for spicy foods.

The anorexic effect of DL-fenfluramine is dependent on animals' habituation to different food types.

As rates of obesity and diabetes have increased dramatically over the past few decades, the use of anti-obesity drugs has now become a routine therapeutic measure. However, the pharmacological effects of chronic use of these drugs in humans frequently lead to reduced efficacy in reducing appetite and body weight through as-yet-unidentified mechanisms. An example of this can be found in animal studies where the appetite suppressant DL-fenfluramine (FEN) is chronically administered and its tolerance develops in animals and humans. The appetite effects of FEN are typically measured in several animal studies by the feeding changes in a balanced standard diet. To determine whether FEN differentially altered appetite suppression in animals with long-term expression with different macronutrient diet compositions, its anorexic effects were measured specifically in male rats that had previously been chronically maintained on normal chow (NC) or a high-fat and high-carbohydrate western diet (WD). Three experiments were conducted by feeding the animals either NC or WD for 1 month to habituate them with their diet. Animals maintained on either NC or WD were subsequently offered both diet options ad libitum for a 2- or 7-day adaptation period while receiving daily systemic FEN treatment. The results suggested that long-term habituated food affected the food preference of animals and their appetite even after chronic systemic FEN administration. Therefore, the effectiveness and success or failure of repeated use of chronic anti-obesity drugs may depend on habituated food type. The appetite suppressant effect was found to be determined by the palatability of a specific macronutrient and the habituated food rather than by a change in the concentration of the administered FEN. This results in a critical analysis of the rationale for taking medication considering the patient's past dietary habits to achieve successful weight loss.

Diet variety sup the relationship between appetite and micronutrient intake in patients with heart failure.

Eating a varied diet promotes adequate micronutrient intake. Poor appetite could decrease the desire to eat a varied diet leading to dietary micronutrient insufficiencies. The interrelationships among appetite, diet variety, and dietary micronutrient intake have not been investigated in patients with heart failure (HF). The purpose of the study was to determine whether the relationship between appetite and micronutrient insufficiency was mediated through diet variety. A total of 238 patients with HF, mean age 61 ± 12.1; 68% male, and 45% NYHA class III/IV were included in this secondary analysis. Data collection consisted of a 4-day food diary and self-reported appetite on a 10-point visual analogue scale. Micronutrient insufficiency was defined as the total number of 17 minerals and vitamins that were insufficient in the diet. Diet variety was calculated as the number of 23 food types consumed over the 4 days. Mediation analysis, controlling for covariates age, gender, NYHA class, and body mass index showed that diet variety mediated the relationship between appetite and micronutrient insufficiencies [indirect effect = -0.0828, 95% confidence interval (CI): -0.1585 to -0.0150]. There was no direct effect of appetite on micronutrient insufficiency (c´ = -0.1802; 95% CI = -0.3715 to.0111). Diet variety played a previously unrecognized role in the relationship between appetite and dietary micronutrient intake in patients with HF. More research is needed to validate these associations in patients with HF.

Doğrusal ARDL ve doğrusal olmayan ARDL modellerinden elde edilen bulgulara göre BIST Mali ve RISE endeksleri arasında uzun dönemli eşbütünleşme ilişkisinin olduğu tespit edilmiştir. Doğrusal ARDL model uzun dönem katsayısına göre RISE endeksinde meydana gelen %1’lik artışın BIST Mali endeksinde yaklaşık %44’lük bir artışa sebep olduğu, doğrusal olmayan ARDL model sonuçlarına göre ise RISE endeksinde pozitif değişimlerde meydana gelen %1’lik artışın BIST Mali endeksinde yaklaşık %46’lık bir artışa, negatif değişimlerde meydana gelen %1’lik artışın BIST Mali endeksinde yaklaşık %43 artışa sebep olduğu gözlemlenmektedir. Dolayısıyla endeksler arasında uzun dönemli asimetrik bir eşbütünleşme ilişkisinin olduğu söylenebilmektedir. Bulgulara ek olarak Toda &amp; Yamamoto Granger nedensellik testleri sonuçlarına göre BIST Mali endeksinden RISE endeksine doğru tek yönlü nedensellik ilişkisi, Hatemi-J (2012) asimetrik nedensellik test sonuçları göre ise RISE endeksindeki negatif şoklardan, BIST Mali endeksindeki negatif şoklara, RISE endeksindeki negatif şoklardan, BIST Mali endeksindeki pozitif şoklara, BIST Mali endeksindeki pozitif şoklardan RISE endeksindeki pozitif şoklara, BIST Mali endeksindeki negatif şoklardan RISE endeksindeki negatif şoklara doğru asimetrik nedensellik ilişkisi tespit edilmiştir.

Economic policy uncertainty, entrepreneurial risk appetite, and corporation innovation in innovative cities – empirical evidence from the Shenzhen Special Economic Zone

PurposeThis study investigates the impact of economic policy uncertainty on corporation innovation in innovative cities. The study sheds light on different results from the previous literature by testing the moderator effects of entrepreneurial risk appetite on such impact.Design/methodology/approachA static panel estimator is applied to a Chinese sample of 416 firm-year observations from 2010 to 2019. This paper uses regression model to test the impact of uncertainty on enterprise innovation in innovative cities, and to test the regulatory role of entrepreneurial risk appetite. For a series of robustness analysis conducted by the author to deal with endogeneity, the results are robust.FindingsThe author finds reliable evidence that the economic policy uncertainty can promote corporations to invest more in R&D in innovative cities. In addition, the role of the entrepreneurial initiative is significant, and there is a positive moderating effect of entrepreneurial risk appetite between policy uncertainty and corporation innovation.Research limitations/implicationsFrom a practical point of view, this study examines the impact of economic policy uncertainty on corporation innovation in innovative cities for the first time. It emphasizes the role of entrepreneurial risk-taking in the development of corporation innovation in Shenzhen, an innovative city. This research is of great significance to the formulation of government policies and the innovative choice of entrepreneurs. In addition, the research shows that the entrepreneurial risk appetite in innovative cities can have a positive impact on enterprise innovation. Therefore, when formulating policies, the government should take the subjective factors of entrepreneurs into account and support enterprises with innovation potential. The evidence of this study also helps entrepreneurs make innovative decisions and enhance their confidence in enterprise development.Originality/valueBy studying the impact of economic policy uncertainty on enterprise innovation under the regulation of enterprise risk appetite, this study shows the subjective and positive role of entrepreneurs in risk grasp in innovative cities for the first time. In addition, it fills the gap of the impact of policy uncertainty on innovative urban enterprises. In fact, although it is traditionally believed that economic policy uncertainty has a negative impact on enterprise innovation, the sensitive findings of this study reveal completely different results from previous studies.

Is bank risk appetite relevant to bank default in times of Covid-19?

The paper aims to analyze the effect of bank risk appetite on banks' default probabilities during the year of COVID-19 in 12 countries while controlling for bank-specific and country-specific effects over time. A System Generalized Methods of Moments (GMM) model of default probabilities is estimated over the periods 2010–2021. This study confirms the ‘risk-mitigation view’, in which banks with higher ESG scores are more prudent in lending and have better relationship management, reducing the probability of bank default. Underperforming banks tend to have a higher portion of risky loans in their credit portfolio and therefore demonstrating a higher default propensity. Bank risk appetite, ESG, asset quality, economic growth, and currency depreciation appear to be material drivers for bank risk. We find that a lower risk appetite ratio (corresponding to higher risk appetite) is associated with higher estimated default probability during the COVID-19 outbreak, identified through interaction with a single time dummy for 2020 (the break-out year of the pandemic).

Examining the Moderating Role of Behavioral Willingness on Indirect Relations Between Alcohol Expectancies and Negative Consequences.

Alcohol expectancies are directly linked to alcohol misuse and indirectly linked to negative consequences via use. Likewise, willingness to experience negative consequences imparts direct risk for negative consequences and may represent an important individual difference when predicting risky alcohol use. To date, no studies have examined how willingness to experience consequences may moderate relations between expectancies and alcohol use in the prediction of negative consequences. It is possible that those who expect appetitive effects and are high in willingness may discount the severity of negative consequences and drink more to realize positive expectations. Alternatively, those who expect aversive alcohol-related effects and are high in willingness may drink more to overcome negative experiences. The current study tested these hypotheses in a sample of undergraduate students (N = 657) from a larger study focused on alcohol and cannabis co-use. Findings suggested that high-arousal positive expectancies (e.g. sociable, lively, talkative) function as a risk factor for negative consequences indirectly through heavier drinking, whereas low-arousal positive (e.g. mellow, relaxed) expectancies served as an indirect protective factor against negative consequences through lighter drinking. Willingness to experience negative consequences had direct and indirect effects on negative consequences through drinking but did not interact with alcohol expectancies. The present study demonstrates the utility of assessing the full range of alcohol expectancies and behavioral willingness in continued research into the dynamic nature of antecedents to alcohol misuse and negative consequences.

Enzymatic Chicken Pulp Promotes Appetite, Digestive Enzyme Activity, and Growth in Litopenaeus vannamei.

Enzymatic chicken pulp (ECP) is an animal protein source that has been proven to be of excellent nutritional content and good quality for the majority of aquatic organisms because of its quality protein, small peptides, palatability, vitamins, and minerals. An 8-week nutritional trial was conducted to assess the effects of an ECP-based diet on the growth performance, digestive enzyme activity, and gene mRNA expression of Pacific white shrimp (Litopenaeus vannamei). Fish soluble pulp (FSP) served as the control group while in the experimental groups, and ECPs with three protein contents were used to replace FSP in equal amounts, named ECP1, ECP2, and ECP3, respectively. No significant difference in weight gain rate, specific growth rate, survival rate, or feed conversion ratio was observed (p > 0.05) between the groups. Ash content in the Pacific shrimp’s whole body was significantly higher in the ECP1 and ECP3 groups compared to the other groups (p < 0.05). Intestinal amylase and protease activities were the highest in the ECP1 and ECP2 groups, respectively (p < 0.05). With respect to gene mRNA expression, neuropeptide Y, excitatory amino acid transporter, and fatty acid transport protein 4 were significantly high in the ECP1 group (p < 0.05). In conclusion, these three ECPs have their advantages to replace FSP in shrimp feed, but ECP1 is more effective if the effects of digestive enzyme activity, appetite, and expression of growth-related genes are considered.

Approaching Addiction

AbstractThis essay seeks to illuminate the shifting definitions of addiction over time by providing a brief, anecdotal history of addiction as well as a review of how it has been conceptualized by the American Psychiatric Association’s DSM classification system. While all addictions have in common the attempt to experience an appetitive effect (satiety), preoccupation, loss of control, and negative or undesired consequences, including physical danger, social complaints, or inability to carry on one’s life roles, the meaning of addiction has not always been consistent. By approaching addiction from the historical/anecdotal and the official/medical perspectives, this essay provides a framework for working toward a common understanding of this complex phenomenon.

Metabotropic group II glutamate receptors mediate cue-triggered increases in reward-seeking behaviour.

Reward-associated cues can invigorate reward-seeking actions via Pavlovian-to-instrumental transfer (PIT). Glutamatergic neurotransmission mediates the appetitive effects of reward-associated cues. We characterized the expression of PIT and its mediation by metabotropic group II glutamate (mGlu2/3) receptor activity in female and male rats. Across the sexes, we used PIT procedures to determine (i) cue-triggered increases in instrumental responding for water reward (experiment 1) and (ii) the respective influences of the mGlu2/3 receptor agonist LY379268 and thirst satiation on this effect (experiment 2). Water-restricted female and male Sprague-Dawley rats learned to lever press for water. Separately, they learned that one of two auditory stimuli predicts free water (CS + vs CS -). On PIT test days, the CS + and CS - were presented independent of instrumental responding, and we measured effects on lever pressing under extinction (no water). In experiment 1, we characterized PIT across the sexes. In experiment 2, we measured PIT after systemic LY379268 administration (0, 0.3 and 1mg/kg) and thirst satiation, respectively. Female and male rats showed similar PIT, with CS + but not CS - presentations potentiating water-seeking behaviour. LY379268 (1mg/kg) attenuated CS + evoked increases in both water-associated lever pressing and conditioned approach to the water port. Thirst satiation attenuated both water-seeking and CS + evoked conditioned approach behaviour. The sexes show similar cue-triggered increases in reward seeking, and thirst satiation suppresses both water-seeking and cue-triggered anticipation of water reward. Finally, across the sexes, mGlu2/3 receptor activity mediates cue-triggered increases in reward seeking.

A Sports Nutrition Perspective on the Impacts of Hypoxic High-Intensity Interval Training (HIIT) on Appetite Regulatory Mechanisms: A Narrative Review of the Current Evidence.

High-intensity interval training (HIIT) and low-oxygen exposure may inhibit the secretion of appetite-stimulating hormones, suppress appetite, and inhibit dietary intake. Physiological changes affecting appetite are frequent and include appetite hormone (ghrelin, leptin, PYY, and GLP-1) effects and the subjective loss of appetite, resulting in nutritional deficiencies. This paper is a narrative review of the literature to verify the HIIT effect on appetite regulation mechanisms and discusses the possible relationship between appetite effects and the need for high-intensity exercise training in a hypoxic environment. We searched MEDLINE/PubMed and the Web of Science databases, as well as English articles (gray literature by Google Scholar for English articles) through Google Scholar, and the searched studies primarily focused on the acute effects of exercise and hypoxic environmental factors on appetite, related hormones, and energy intake. In a general normoxic environment, regular exercise habits may have accustomed the athlete to intense training and, therefore, no changes occurred in their subjective appetite, but there is a significant effect on the appetite hormones. The higher the exercise intensity and the longer the duration, the more likely exercise is to cause exercise-induced appetite loss and changes in appetite hormones. It has not been clear whether performing HIIT in a hypoxic environment may interfere with the exerciser’s diet or the nutritional supplement intake as it suppresses appetite, which, in turn, affects and interferes with the recovery efficiency after exercise. Although appetite-regulatory hormones, the subjective appetite, and energy intake may be affected by exercise, such as hypoxia or hypoxic exercise, we believe that energy intake should be the main observable indicator in future studies on environmental and exercise interventions.
