The AI answer we saw
Whey isolate contains 90%+ protein with minimal lactose and fat, making it ideal for weight loss due to higher protein density and fewer calories. Whey concentrate has 70-80% protein with more lactose and fat but is more affordable. For weight loss, isolate is technically superior for maximizing protein intake while minimizing calories, but concentrate works well if budget is a concern. Both support muscle retention when combined with resistance training and calorie deficit.
