Abstract Objectives Although the effectiveness of high-intensity training has been widely recognized as positive in athletes, its application in a clinical context is not well established. There is enough evidence to confirm that high-intensity routines are safe and that at-risk populations, such as for overweight and obese subjects, can help from these weight loss treatments. The purpose of this study was to lead a trial to test whether manipulation of physical activity in extension to high protein diet intake would induce changes in total weight and body composition. Methods Sixty-eight healthy male volunteers were randomly assigned to one of the experimental groups: a control group with a low-level prescription of physical activity (1–4 METs), moderate physical activity group that performed 10.000 steps walking per day (5–8 METs) and intense physical activity group that trained exercises by at least 70% of VO2max three times a week (> 8 METs). All subjects followed a high-protein diet designed with a reduction of 500 kcal/day. Nutritional counseling was provided throughout the study period to help ensure dietary adherence. This intervention was delivered over twenty-four sessions as weekly one-on-one, face-to-face 30-min consultations. Results A significant reduction in body fat percentage was observed in the intense physical activity group (-20.9 ± 8.8 (CI95%: -25.6 – -16.2), p < 0.001). The change in muscle mass did not produce any significant differences between groups (p > 0.05). Concerning weight, a notable weight loss was found in those subjects who performed moderate or intense physical exercise, vs. those who did light exercise, (p < 0.001) and (p < 0.003), respectively. Conclusion our data strongly suggest that resistance training should be included, whenever possible, in any dietary treatment for improving the body composition of men with overweight or obesity.

OBJECTIVE The fat mass and obesity-associated gene (FTO) variant has shown the strongest association with obesity. Recent studies suggest that dietary intake may modify the genetic effects of FTO. We tested the effect of FTO variant on long-term weight loss and change in body composition in a 2-year randomized intervention trial. RESEARCH DESIGN AND METHODS FTO SNP rs1558902 was genotyped in 742 overweight or obese adults who were randomly assigned to one of four diets differing in the percentages of energy derived from fat, protein and carbohydrate (20, 15, and 65%; 20, 25, and 55%; 40, 15, and 45%; and 40, 25, and 35%) in the Pounds Lost Trial for 2 years. Body composition and fat distribution were measured in 424 and 195 participants by Dual-energy X-ray absorptiometry (DXA) and computed tomography (CT), respectively. RESULTS We found significant modification effects for diet intervention varying in protein (low vs high), but not in fat, on 2-year changes in total fat, fat free mass (FFM), fat mass% (FM%), trunk fat%, total adipose tissue mass (TAT), visceral adipose tissue mass (VAT) and superficial adipose tissue mass (SAT) (P for interactions=0.045, 0.036, 0.033, 0.048, 0.001, 0.008 and 0.002, respectively). Carriers of the risk allele (A allele) had a greater loss of weight and regional fat in response to high protein diet, while an opposite genetic effect was observed on changes in TAT and SAT in response to low protein diet at 2 years. Significant gene by diet interventions (low vs high protein) were also observed at 6 months of intervention, when the maximum of weight-loss was achieved, for changes in FFM, TAT, VAT and SAT (P for interactions=0.007, 0.019, 0.036 and 0.041, respectively). Patterns of change in body composition and fat distribution by diet intervention were similar at 6 month and 2 year. CONCLUSIONS Our data suggest that a high-protein diet may be beneficial for weight loss in individuals with the risk allele of the FTO variant rs1558902.

Abstract Background There is evidence showing the effectiveness of a hypocaloric diet and the increase in physical activity on weight loss. However, the combined role of these factors, not only on weight loss but also body composition, remains unclear. The purpose of this study was to investigate the effect of a hypocaloric diet on the body composition of obese adult women throughout different degrees of physical activity during a weight loss program. Methods One hundred and seventeen healthy female volunteers were randomly assigned to one of the experimental groups: a control group with a low-level prescription of physical activity (1–4 METs), moderate physical activity group that performed 10.000 steps walking (5–8 METs) and intense physical activity group that trained exercises by at least 70% of VO2max three times a week (> 8 METs). All subjects followed a hypocaloric diet designed with a reduction of 500 kcal/day. Nutritional counseling was provided throughout the study period to help ensure dietary adherence. Results We found no differences in body weight compared to moderate and intense physical activity (ßstand. = − 0.138 vs. ßstand. = − 0.139). Body fat was lower in women following an intense activity (ßstand. = − 0.436) than those with moderate exercise (ßstand. = − 0.231). The high-intense activity also increased muscle mass at the end of the intervention, standing out above the moderate activity (ßstand. = 0.182 vs. ßstand. = 0.008). Conclusions These findings indicate that a hypocaloric diet, without prescription of physical activity, is adequate to lose weight in the short term (12 weeks), but physical activity is vital to modify the body composition in women with obesity. Body fat was lower when women practiced a moderate exercise compared to hypocaloric diet only, but an intense physical activity was the most effective protocol to obtain a reduction of body fat and maintain muscle mass. Trial registration The study protocol complied with the Declaration of Helsinki for medical studies, it was approved by the bioethical committee of Córdoba University, in the Department of Health at the Regional Government of Andalusia (Act n°284, ref.4156) and retrospectively registered in clinicaltrials.gov (NCT03833791).

The effects of long-term high-protein consumption (i.e., >2.2 g/kg/day) are unclear as it relates to bone mineral content. Thus, the primary endpoint of this investigation was to determine if consuming a high-protein diet for one year affected various parameters of body composition in exercise-trained women. This investigation is a follow-up to a prior 6-month study. Subjects were instructed to consume a high-protein diet (>2.2 g/kg/day) for one year. Body composition was assessed via dual-energy X-ray absorptiometry (DXA). Subjects were instructed to keep a food diary (i.e., log their food ~three days per week for a year) via the mobile app MyFitnessPal®. Furthermore, a subset of subjects had their blood analyzed (i.e., basic metabolic panel). Subjects consumed a high-protein diet for one year (mean ± SD: 2.3 ± 1.1 grams per kilogram body weight daily [g/kg/day]). There were no significant changes for any measure of body composition over the course of the year (i.e., body weight, fat mass, lean body mass, percent fat, whole body bone mineral content, whole body T-score, whole body bone mineral density, lumbar bone mineral content, lumbar bone mineral density and lumbar T-score). In addition, we found no adverse effects on kidney function. Based on this 1-year within-subjects investigation, it is evident that a diet high in protein has no adverse effects on bone mineral density or kidney function.
