This study evaluates the effects "High Protein Atkin's Complete (lacto) VEgetaRian Diet (Acronym; 'PACER' diet) on weight, body composition and metabolic profiles in obese Asian Indians subjects living in north India.

Increasing the protein consumption promotes weight loss through several mechanisms. Diets high in protein promote energy expenditure through increased postprandial thermogenesis, increase total daily expenditure and increase satiety as compared to carbohydrate. The present study aims to evaluate the effects "High Protein Atkin's Complete (lacto) VEgetaRian Diet (Acronym; 'PACER' diet) on weight, body composition and metabolic profiles in obese Asian Indians subjects living in north India.
