If you're overweight and eat a lot of protein—especially from whey—for a month, your blood sugar might go up a bit, but only if you're also eating very little saturated fat. If you eat more saturated fat, that same high-protein diet doesn't seem to affect your blood sugar.

When people who lost weight eat more protein and fewer carbs, their bodies burn more calories at rest and end up in a calorie deficit, which might help them keep the weight off.
