A Trial of the Ideal Protein System Versus Low Fat Diet for Weight Loss

2018-05-11 16:08:07 | BioPortfolio


This study will examine whether, compared to a standard, low-fat, calorie-restricted diet intervention, the clinic-supported Ideal Protein weight loss method will result in greater weight loss and improvement in cardiometabolic risk factors over 3 months among obese adults. We expect to learn more about the impact of different food and nutrient combinations on the body and weight loss.


Restricting total calorie intake is emphasized in the 2013 American Heart Association/ American College of Cardiology/ The Obesity Society Guideline (AHA/ACC/TOS) for the Management of Overweight and Obesity in Adults for its effectiveness at reducing body weight and decreasing cardiometabolic risk factors. An implication of this focus on total quantity of calories consumed is that macronutrient composition of dietary intake and its effects on the hormonal milieu that regulates adipose accumulation in the human body do not play a significant role in weight loss. Such recommendations and the results of limited previous studies have led to the advice that all weight loss diets regardless of macronutrient composition will produce the same degree of weight loss if adherence to the diet is similar. In contrast, our previous studies have shown that despite comparable adherence to dietary goals, participants losing weight on a moderately carbohydrate-restricted, adequate protein regimen have improved cardiometabolic indicators as compared to those restricting fat. The RENEWAL trial will provide unique data on the efficacy of the Ideal Protein method (moderate carbohydrate restriction and adequate protein) for weight loss and improvement in cardiometabolic risk factors. The interventions will include a significant proportion of African-Americans, a group with very high rates of obesity which is often under-represented in trials examining the effects of weight loss diets. Findings from this trial may offer new evidence for the recommendation of specific macronutrient and behavioral approaches to the reduction of cardiometabolic risk factors.

Medical and Biotech [MESH] Definitions

Expected weight of a healthy normal individual based on age, sex, and height. Thus, a malnourished person would weigh less than their ideal body weight.

Decrease in existing BODY WEIGHT.

An eating disorder that is characterized by the lack or loss of APPETITE, known as ANOREXIA.
