“…Overall, high-protein diets have been shown to improve body composition through alterations in satiety, muscle protein synthesis and TEF (19) . The higher satiety of high-protein diets can be attributed to increases in anorexigenic hormones (cholecystokinin, glucagon-like peptide-1, peptide YY, leptin), combined with decreases in orexigenic hormones (ghrelin) (19) . Higher protein intakes have also been shown to retain lean body mass and promote fat loss in a energy-restricted state (20)(21)(22) .…”

The purpose of this study was to determine the effect of a whole-food protein (cottage cheese, CC) consumed before sleep on next-morning resting energy expenditure (REE), RER and appetite compared with an isoenergetic/isonitrogenous casein protein (CP) supplement and placebo (PL) in active women. In a beverage-blinded, randomised, cross-over design, ten active women (age, 23·1 (sd 1·9) years; body fat, 22·0 (sd 4·6) %) consumed pre-sleep CC (30 g of protein, 10 g of carbohydrate and 0 g of fat) or energy- and protein-matched liquid CP or PL (0 kJ). Participants arrived at 18.00 hours for an overnight stay in the laboratory. At 30–60 min before normal bed time (2 h post standard meal), participants consumed CC, CP or PL before measurement of REE. Upon waking (05.00–08.00 hours), REE was repeated and subjective appetite was recorded. Statistical analyses were conducted using repeated-measures ANOVA (SPSS). Significance was accepted at P≤0·05. There were no significant differences in acute REE (CC, 7217 (sd 1368); CP, 7188 (SD 895); PL, 7075 (sd 1108) kJ/d, P=0·95), acute RER (0·79 (sd 0·05), P=0·56), morning REE (CC, 5840 (sd 1225); CP, 5694 (sd 732); PL, 5991 (sd 903) kJ/d, P=0·79) or morning RER (0·77 (sd 0·03), P=0·52). Subjective measures of appetite were not different between groups. In active women, pre-sleep consumption of CC does not alter REE or RER more than a CP or PL beverage. These data suggest that the metabolic response from whole-food protein do not differ from the metabolic response of liquid protein.

“…The diet of this study was hypocaloric with a reduction of 500 kcal/day during the treatment period to achieve a weekly weight loss of 400 grams, an amount that is a safe, achievable, and clinically meaningful goal for weekly weight loss [32]. Dietary protein intake was set at 1.8 g/kg of body mass, as higher protein consumption has been shown to help offset losses in lean tissue mass and promote greater adherence to the nutritional regimen [33]. No vitamins or other nutritional complements were prescribed.…”

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.

“…Greater habitual protein intake has been shown to be associated with lower BMI, lower waist circumference, and improved cholesterol, especially in overweight and obese individuals [8]. More importantly, higher protein intake has been shown to be more favorable for improving body composition, promoting fat loss through increases in energy expenditure [9–11]. In blue collar workers, greater habitual protein intake is also associated with greater maximal and explosive strength [12], which is important for firefighter performance [13] and avoiding common injuries (i.e.…”
