Comparison of low calorie high protein and low calorie standard protein diet on waist circumference of adults with visceral obesity and weight cycling

Abstract

ObjectivesMany individuals with visceral obesity who previously had succeeded in reducing body weight regain and this loss–gain cycle repeats several times which is called as weight cycling. We aimed to evaluate the effect of a low calorie high protein diet (HP) compared to a low calorie standard protein diet (SP) on waist circumference of visceral obese adults with history of weight cycling.ResultsIn this open-randomized clinical trial, participants were asked to follow dietary plan with reduction in daily caloric intake ranging from 500 to 1000 kcal from usual daily amount with minimum daily amount of 1000 kcal for 8 weeks and were divided in two groups: HP group with protein as 22–30% total calorie intake; and SP group with protein as 12–20% total calorie intake. There was a statistically significant difference (P < 0.001) between waist circumference before and after the dietary intervention among both groups. Meanwhile, there was no statistically significant difference in the mean reduction of waist circumference between HP and SP groups (P = 0.073). Taken together, the protein proportion does not significantly affected waist circumference.Trial registration ClinicalTrials.gov NCT03374150, 11 December 2017Electronic supplementary materialThe online version of this article (10.1186/s13104-018-3781-z) contains supplementary material, which is available to authorized users.

The effect of 12 weeks of euenergetic high-protein diet in regulating appetite and body composition of women with normal-weight obesity: a randomised controlled trial

“…Our observation is consistent with the results reported by previous studies (62)(63)(64)(65) . A study showed that, in a SPan of 16 weeks, the more abdominal fat loss occurred with an HP diet that contained 27 % of total energy from dietary protein than with a diet that contained 16 % protein (66) . Moreover, Farnsworth et al showed that higher protein intake (2•2 g protein/kg per d) significantly decreased the waist:hip ratio than the control group, suggesting that this reduction might be contributed to a decline in abdominal fat (47) .…”

Is protein the forgotten ingredient: Effects of higher compared to lower protein diets on cardiometabolic risk factors. A systematic review and meta-analysis of randomised controlled trials

“…Since the 2012 review [19], fourteen studies have been published on the effect of HP compared to LP diets on various cardiometabolic risk factors (e.g. body weight, blood pressure, lipid outcomes) [21][22][23][24][25][26][27][28][29][30][31][32][33][34]. Therefore, a renewed analysis with up-to-date evidence is warranted.…”

The impact of type of dietary protein, animal versus vegetable, in modifying cardiometabolic risk factors: A position paper from the International Lipid Expert Panel (ILEP)

“…Based on the proportion of protein consumption, participants were divided into 2 groups: (1) the high protein (HP) group (22e30% protein, 50e55% carbohydrate and 20e25% fat), and, (2) standard protein (SP) group (12e20% protein, 55e60% carbohydrates and 20e30% fats). The waist circumference (WC) was significantly decreased, from 96.13 ± 8.19 to 90.09 ± 8.62 cm (p < 0.001), after 8 weeks of protein-rich low-calorie diet intervention [35]. This study showed that the specific dietary intervention reduce visceral fat and it is recommended as a possible treatment or prevention of visceral obesity [35].…”
