Low glycemic index diets are better then high protein diets
Australian analysis team lead by Dr. Jennie Brand Miller at the University of Sydney conducted a trial in which 129 overweight subjects ages 18 to 40 were randomly assigned to one of four weight-loss diets for 12-week. All four diets were comprised of reduced fat (30 percent of total energy intake) and held daily calories to 1400 kcal for girls and 1900 kcal for men.
This was the primary clinical trial comparing the effects of glycemic index and high-protein diets on weight loss and cardiovascular risk.
The diets varied in target levels of carbohydrates, proteins, and glycemic load (i.e., glycemic index multiplied by the amount of carbohydrate, divided by 100) as follows:
Diet 1: carbohydrates comprise 55 % of total energy intake, protein fifteen percent of total energy intake, high glycemic load (127 g)
Diet 2: similar to diet one except a lower glycemic load (75g)
Diet 3: protein includes 25 percent total energy intake (primarily based on lean red meat), carbohydrate reduced to 45 percenttotal energy of intake, and high glycemic load (87 g)
Diet 4: Just like diet three, except low glycemic load (54 g).
Brand-Miller and her team report {that the} diets resulted in similar reductions in weight (4.2 percent to 6.2 percent of body weight), fat mass and waist circumference.
But, in the high-carbohydrate diets, lowering the glycemic load doubled the fat loss. The investigators also found that total and LDL (“dangerous”) cholesterol levels increased with diet 3 and decreased in diet2.
In the short term findings suggest that dietary glycemic load, and not simply overall energy intake, influences weight loss,
Foods with a low degree of starch gelatinization, like pasta, and people containing a high level of viscous soluble fiber, like wholegrain barley, oats, and rye, have slower rates of digestion and lower glycemic index values.
While not any drastic change in regular dietary habits, one will simply replace high glycemic index grains with low glycemic index grains and starchy vegetables with less starchy ones and abate on softdrinks, that are usually poor in nutrients yet~however~nevertheless~nonetheless

The diets varied in target levels of carbohydrates, proteins, and glycemic load (i.e., glycemic index multiplied by the amount of carbohydrate, divided by 100) as follows:
Diet 1: carbohydrates comprise fifty five percent of total energy intake, protein fifteen percent of total energy intake, high glycemic load (127 g)
Diet 2: kind of like diet 1 except a lower glycemic load (75g)
Diet 3: protein includes 25 percent total energy intake (based mostly on lean pork), carbohydrate reduced to 45 percenttotal energy of intake, and high glycemic load (87 g)
Diet 4: Just like diet three, except low glycemic load (54 g).

But, in the high-carbohydrate diets, lowering the glycemic load doubled the fat loss. The investigators also found that total and LDL (“unhealthy”) cholesterol levels increased with diet 3 and decreased in diet2.
