When I was younger, I could eat superhuman amounts of food and not gain an ounce (I was even accused of having anorexia by strangers because I was so thin).
Now, if I even think about one serving of ice cream, I gain ten pounds. Oh shit, I’ve done it. Back to the treadmill, I guess.
I always hated sugar, and ate 3 large meals a day. Huge breakfast, lunch, dinner, midnight snacks. Never gained at all.
That all changed after my pregnancy at 28. Suddenly I seemed to gain weight through osmosis. I mostly lost interest in food, and only started eating sensible quantities twice a day.
Now I can’t lose weight at all, even with nearly a gallon of water per day and one small cup of food every day or two (to be fair, my body now rejects most food because of an autoimmune disorder), but I can actually gain weight on less than 500 calories a day. It doesn’t make sense by conventional logic, yet here I am. I mostly live on Ensure and Pedialyte, yet I weigh more than I ever have. It’s really weird.
