Thread: Yo-yo dieting and immunity

I thought this might be interesting for those of us who go on bulk/cut cycles or competition diets.

Frequent intentional weight loss may have significant long-term detrimental effects on the immune system...

The more times one loses weight, the less effective one's natural killer cells become.

Full story here.

True. But it's something to be aware of -- I know I'm going to try to be more dedicated about my sleep, antioxidants and multis with this in mind.

As well, in the lines of lifetime athletes, I have seen studies of runners showing that a lot of high-impact exercise also affects immunity -- actual damage to the blood cells apparently. Which considering that for some of us cutting also involves nutty amounts of cardio might also have a bearing.
