A high-protein, low-fat, low-glycemic index diet reduces calorie intake by 25 percent compared to a high-carbohydrate, low-fat diet and reduced triglycerides by 35% according to a recent study. Subjects
Subjects : 12 overweight men
The study involved 12 overweight men who were fed different diets a couple weeks apart.
Calorie intake : 2106 calories vs 2794 calories
When fed the high-protein, low-fat, low-glycemic index diet, they ate 2106 calories compared to 2794 calories when fed the high-carbohydrate, low-fat diet which is the phase 1 diet recommended by the American Heart Association.
Higher HDL, smaller LDL, lower insulin levels
Other benefits seen when the men were fed the high-protein, low-fat, low-glycemic index diet compared to the high-carbohydrate, low-fat diet included high HDL levels, smaller LDL particle size, “marked decreases” in insulin levels while fasting, throughout the day, and following a glucose load.
Conclusion : High-protein, low-fat, low-glycemic index diet reduces cardiovascular risk factors
“Thus, a low-glycaemic index-low-fat-high-protein content diet may have unique beneficial effects compared with the conventional [American Heart Association] diet for the treatment of the atherogenic metabolic risk profile of abdominally obese patients,” the paper concluded.
