A guy that I used to work security with for many years...WAS one of Stallones bodyguards in the 80's. He told me that Stallones diet for most of the films at this time was multiple feedings of 3.5 ounce poptop cans of tuna per day, diet soda, Black coffee with Sweet & Lo....And the only carbs came in the form of homemade DRY AS FUCK oatmeal cookies made from quick oats, water, sweet&lo, raisins and cinnamon. Baked on a tray. Made very small. Stallone would only eat carbs in this form..on days when he had to film shirtless. Otherwise...ZERO carbs everyday from tuna, coffee, diet soda, and water.
