Eat the same, weigh the same, leads to old fat accumulation that never gets recycled. The body only burns what it takes in and needs, then stores the rest. If you’re always eating the same, those fat stores don’t get replenished with fresh fat.
Your fat contains the toxins and all the junk that you consume in one way or the other, that doesn’t get processed, assimilated or eliminated through waste channels.
I personally think it’s better to deplete those fat cells now and then in order to eliminate the debris in the cells that has no purpose except to muck up the works and keep the cells from functioning optimally.
So go ahead, do THE YOYO.
