I had 2 protein shakes the last 2 nights which I put chia and flax seeds in. All day today I feel very bloated. Don't know if it is from this. I cut out fruit today except 1/2 an avocado in the a.m. Skipped breakfast for 2 days. The first took a l lb. off. The second brought 1/2 lb back. I have eaten onions, tomatoes, -- not sure if this does it.
I've said this elsewhere but shakes become shakes by blending air into the liquid in order to whip it up. And then you swallow this air when you drink it. So it may be that shakes themselves are just too bloat-inducing for you, regardless of their contents.
