paleo'ish/primal'ish eater under doctor's supervision. All blood work and medical test fantastic. Lost a tremendous amount of fat and gained a lot of muscle mass. Skin, hair, nails, eyes, just overall appearance is so much better. I'm into a size 4/6 with a weight loss of 30 - 40 pounds. I think I've pretty much settled into my ideal weight.
This is what my body does best with. I don't necessarily believe it's for everybody especially if there are religious/spiritual/moral beliefs regarding the eating of meat/fish.
I think it is always important to check with one's doctor if making a substantial diet change especially if one is dealing with diabetes or any body/organ disease.
