Diet
and Exercise. The amount
of weight lost doesn’t have to be
dramatic. As an example, for someone
who weighs 200 pounds, a drop of
5–7 percent would mean losing
between 10 and 14 pounds. Most
people with prediabetes or type
2 diabetes are overweight, and any
dietary changes that produce weight
loss are likely to lower blood sugar.
However, a study comparing low-fat
and low-carb diets among type
2 diabetics, published in the American
Journal of Clinical Nutrition, found
that a low-carb, low-sugar diet
produced more stable levels of
healthy blood sugar and less need
for diabetes medications.
