Abstract
Previous studies using probiotics have shown strain-dependent effects on body mass index (BMI), body mass, or fat mass (FM). The aim of this study was to evaluate how the addition of yogurt containing Lactobacillus acidophilus LA-5 and Bifidobacterium animalis subsp. lactis BB-12 strains to a diet plan affects selected anthropometric parameters in obese people on an energy-restricted diet. Fifty-four subjects aged 20–49 (34.52 ± 9.58) years were included in this study. The recruited subjects were assigned to two subgroups: consuming probiotic yogurt along with a hypocaloric diet (GP) (n–27) or the same diet but without an intentional introduction of yogurt (GRD) (n–27) for 12 weeks. Both GP and GRD decreased body weight, BMI, fat mass and visceral fat by 5.59 kg and 4.71 kg, 1.89 and 1.61 kg/m2, 4.80 kg and 4.07 kg, and 0.68 and 0.65 L, respectively, although the obtained differences were not significant. Analysis of GP and GRD results separately at the beginning and end of the intervention showed that fat loss was substantial in both groups (p < 0.05). Consumption of yogurt containing LA-5 and BB-12 does not significantly improve anthropometric parameters in obese patients.
Highlights
The growing phenomenon of overweight and obesity has led to a global problem
According to the information given above, the purpose of the study was to assess the effect of widely available yogurts containing Lactobacillus acidophilus LA-5 and Bifidobacterium lactis BB-12 strains on selected anthropometric parameters in obese subjects on an energy-restricted diet
In the construction of the above hypothesis, we assumed that a study group is homogenous in the context of dietary compliance and a significance level of p < 0.05 indicating statistically significant differences. This randomized, single-blind study is designed to evaluate the introduction of low-fat yogurt to a diet plan containing Lactobacillus acidophilus LA-5 and Bifidobacterium lactis BB-12 strains on selected anthropometric parameters in obese people on an energy-restricted diet
Summary
The growing phenomenon of overweight and obesity has led to a global problem. Current data estimate that 650 million people are obese worldwide, while 1.9 billion are overweight [1]. The latest trend analyses show that the number of obese or overweight people is steadily increasing both in Europe and around the world [2,3]. The obesity disease is characterized by excessive fat accumulation, which is a consequence of a long-term energy surplus. Changes in eating habits and the increased availability of high-calorie foods have made overweight and obesity one of the most severe health problems of our era. Nearly 2.8 million deaths in the world are a consequence of excess weight [1,4,5]
