2. Whey Protein Isolate
Whey protein isolate can actually be your best friend for losing weight and for keeping precious lean muscle. Don’t buy just any whey though - stick to a clean, whey protein isolate powder which contains no milk fat or milk sugars, unlike whey protein concentrate. I like About Time brand, which is sweetened with stevia instead of sugar or artificial sweeteners. It’s also gluten-free, hormone-free, lactose-free, carb-free, and fat-free, not to mention incredibly delicious.
