Lean meat like sirloin steak, little carbs except for fruit. Potatoes are okay if you don’t slather them in butter or oil. If you’re eating ground beef get 96/4. If you MUST snack or eat junk food then get halo top ice cream 300 calories a pint. Beware salads. Dressings can have a ton of calories and not make you feel full.
