Abstract
To elucidate the acute effect of different high-fat meals accompanied by water or orange juice on subjective appetite sensations. This acute, postprandial study included 39 healthy women (aged 20 to 40 years): 22 participants received a high-monounsaturated fat meal (MUFA) (≈1000 kcal, 56.3% Energy from MUFA) and 17 participants received a high-saturated fat meal (SFA) (≈1000 kcal, 37.6% Energy from SFA). Both interventions were accompanied by 500 ml of water or orange juice. The subjective appetite sensations were evaluated before (fasting) and 1, 2, 3, 4, and 5 hours after the meal intake using the visual analog scale. The subjective area under curve (AUC) appetite sensations and AUC appetite scores were equal after the consumption of high-fat meals from SFA and MUFA. Moreover, the consumption of a high-SFA meal raises the prospective desire to eat something fatty. In addition, the high-SFA meal consumption reduces subjective AUC appetite sensations and AUC appetite scores along the time, compared to a high-MUFA meal, when orange juice consumption followed those meals. Our results demonstrate that high-MUFA meal consumption decreased the desire to intake something fatty, and the high-SFA meal, when followed by orange juice intake, has postprandial appetite sensations suppressed.
Highlights
The positive energy balance occurs when energy intake exceeds energy expenditure (Loh et al 2015, Romieu et al 2017)
Studies have shown that monounsaturated fat acid (MUFA) consumption exhibit higher or similar effects on appetite compared to saturated fatty acid (SFA), evaluated by subjective sensations of appetite – Visual Analog Scale (VAS) – a usual, useful and cheap tool to measure the appetite (Flint et al 2000, 2003)
Student t-test was used to compare the differences in area under curve (AUC) of subjective appetite sensations scale and appetite score between the high-fat meals followed by water or orange juice consumption
Summary
The positive energy balance occurs when energy intake exceeds energy expenditure (Loh et al 2015, Romieu et al 2017). Over the long term, sustained by positive energy balance leads to obesity and represents a risk factor for other chronic non-communicable diseases (Richard 2015, Bray et al 2017). In this context, the consumption of energy-dense foods, especially high-fat meals, are associated with positive energy balance and weight gain by influencing satiation and satiety (Blundell & Macdiarmid 1997, Astrup 2005). There are no studies evaluating the effect of high-fat meals followed by beverages, especially orange juice, on appetite. This study aimed to elucidate the acute effect of orange juice on subjective appetite sensations in different high-fat meals
