Summary

A person's genetic code is believed to affect how much weight he/she will lose during diets that vary in carbohydrate and dietary fat content. 'Carbohydrate responders' are hypothesized to lose more weight on diets that are high in carbohydrates, as compared to high in fats. 'Fat responders' are hypothesized to lose more weight on diets that are high in dietary fat, as compared to high in carbohydrates. The purpose of the proposed study is to test these hypotheses in a randomized controlled trial.

Conditions

Interventions

BEHAVIORAL

High-fat diet

The high-fat diet will consist of \~40% energy from fat and \~45% from carbohydrates. Protein will be 15% of energy. All participants will be assigned an energy intake target that will result in a daily deficit of \~750 kcal, though no energy intake targets below 1,100 kcal/d (women) and 1,300 kcal/day (men) will be prescribed

BEHAVIORAL

High-carbohydrate diet

The high-carbohydrate diet will consist of \~20% of energy from fat and \~65% from carbohydrates. Protein will be 15% of energy. All participants will be assigned an energy intake target that will result in a daily deficit of \~750 kcal, though no energy intake targets below 1,100 kcal/d (women) and 1,300 kcal/day (men) will be prescribed
