People assigned to eat a diet containing 25% protein and 30% fat lost more weight and more fat than a group assigned to eat a diet containing 15% protein and 30% fat.
The study involved 65 overweight and obese people, 50 women and 15 men, who were 18- to 55-years-old.
The average weight loss after 6 months was 19.6 lbs in the 25% protein group vs 11.2 lbs in the 12% protein group.
In other words, those eating a 25% protein diet lost an additional 9.4 lbs.
The average fat loss after 6 months was 16.7 lbs in the 25% protein group vs 9.5 lbs in the 12% protein group.
In other words, those eating a 25% protein diet lost an additional 7.3 lbs of fat.
So the lesson to be learned is that replacing some carbohydrates in your diet with protein increases fat loss and increases weight loss.
