Sylvester Stallone Says His 'Rocky III' Diet Was Just Tuna, Oatmeal Cookies, and Coffee

"My entire breakfast would be maybe two [small] oatmeal cookies made with brown rice, and 10 cups of coffee because I wanted to keep my body fat down to 2.8%," explains Stallone. "I was forgetting my phone number. I was eating just tuna fish. My memory was shot, it was completely gone. I was getting all kinds of debilitating physical effects. But it was for the cause."
