4. Skip the liquid calories. Yes, even beer. It’s just for three weeks, OK? Stick to black coffee, unsweetened tea, and water. You’d be surprised how many calories you can cut from your diet by following this one tip. And if you’re worried your social life will take a nosedive without weekly happy hours, limit yourself to one night out a week. Your waistline and your liver will thank you.
5. Stick to eating real food. And no, Cheetos don’t count. If you can’t track a food’s origins immediately back to a specific plant and/or animal, then it probably shouldn’t be going in your body. Lean meats, fish, fruits, vegetables, beans, nuts, seeds, whole grains in their most natural form, and full-fat dairy (in moderation) are all on the “yes” list.
Will you look like a professional bodybuilder if you follow this plan? No, of course not -- remember, you're the person who waited until there were three weeks before summer to start thinking about getting in shape. You should generally stay active and eat well year round, most of the time.
