I don’t use protein powder. To the best of my knowledge I’m allergic to whey. I just make my own little protein shakes using natural food (milk, milk powder, PB, etc, etc).
I know milk has whey…I think it’s the concentration level that bothers me. If it’s highly concentrated whey I get a bad reaction.[/quote]
You could have used a low quality brand. Never know what else they put into some of those tubs. Some of the companies have been known to add in soy, and other ingredients, without mentioning it on the label.
As far as waist reduction, protein will slow digestion, reducing the insulin bump, and helping keep you insulin sensitive. Also the thermic effect of protein is higher then carbohydrates and fats.
Also if you are gaining LBM, then your metabolism will be increasing too. Increasing protein should give you the building block to help increase muscle mass.
Also since protein digests slower, it leaves you satiated longer, and many people don’t notice they are eating less.
Often an increase in protein is connected to a reduction in carbohydrates, and when this occurs there is an even bigger effect on insulin. This also can result in a reduction in fiber, causing constipation. I learned this the hard way, and now know what women go through in childbirth.
