The effects of various combinations of different protein levels and low or high glycemic index carbs was examined. Over seven hundred patients who had formerly lost about 20 pounds each followed the different diets.
Please note that patients were allowed to eat as much as they wanted. Those who ate mainly high-glycemic index carbs and low protein levels, where protein was 13 percent of calories, re-gained the most weight. Those who ate 25 percent of their calories from protein and enjoyed manly low-glycemic index carbs re-gained the least amount of weight.
I have previously written that low-glycemic carbs can be useful to lose belly fat, and to keep fat producing insulin to low levels.
The best proteins to eat are fish with omega-3 fats, such as wild salmon and sardines. These special fats use up your stored up body fat, and prevent fat accumulation. Eating lots of salmon, sardines, and some chicken, with beans and kale, should produce beneficial effects on your weight. Add lots of other greens, broccoli with olive oil and vinegar, and low-glycemic fruits such as apples to add variety to your nutrition.
