For us who are human, yes. But hams? They will find a way to get out of it. I had a friend, my last friend I tried to keep despite her becoming a ham, and we went on a diet together. I lost weight rapidly, I think I had 7 lbs. She had a good 40, and thats being nice. She couldn't lose weight. She claimed she was only eating "salad" every day. After a month I asked, well Jesus what is in your salad? It was a ranch covered abomination with toppings, bacon, croutons, and iceberg.
