Here’s an interesting one: two sets of mice were fed identical diets of corn starch with equal calories… but the corn starch had a high glycemic index (“GI”) for one group and a low GI for the other. The result: six months later the mice weighed the same!
BUT (the big but), their body compositions differed singificantly: the high GI group had twice the normal amount of fat in their bodies, blood and livers. The low GI diet mice had normal fat levels.
Besides being a good promo for a low GI diet, the results also show that measuring your health by the scales alone is a big mistake.
