For those wishing to lose weight or avoid gaining weight, reducing overall caloric intake is key, perhaps by substituting protein intake in place of both carbohydrate and fat intake, according a to a new study published in the American Journal of Clinical Nutrition.
Researchers examined trends in carbohydrate, fat and protein intakes in adults and their association with energy intake (calories) by tracking intake over time using data from the National Health and Nutrition Examination Survey (NHANES) — a program of studies designed to assess the health and nutritional status of adults and children in the United States.
According to the study, one of the most striking findings was the consistently strong and negative association with increasing percentage calories from protein and daily energy intake across all three body mass index categories (normal weight, overweight and obese) in both NHANES I, 1971-75, and NHANES 2005–2006.
This finding may be surprising to many as it contradicts the belief that the rise in obesity has been caused by increased caloric intake due to the overconsumption of protein-based foods.
