With stage 4 kidney failure, I'm learning to eat in a different manner. I'm on a 50 g of protein diet, trying to stay off of dialysis. Even though I don't have enough energy to do more than walk to the loading room several times a day, I've lost weight, enough that I wouldn't be on the "fat boy" program in the Army when I was in at age 43. 50 g allows 6 ounces of meat per day with a few vegetables thrown in for some vitamins and fiber.
You can't exercise your way out of a deal like this, because it may do more harm than good.
BTW, spam usually has an address to buy their product and this one doesn't have that and doesn't even mention a product.
