Split this breakfast recipe in half to make a healthy snack with 200 calories, 11 grams protein, and 3.5 grams fiber. Not only will it help prep your body for fat burn, but it may also boost your energy levels (so you're more likely to get to the gym, perhaps?): Walnuts are rich in serotonin, a hormone that produces feel-good chemicals in the brain.
This portable, affordable protein is a must-eat for anyone looking to lose a few. Why? Canned tuna is a prime source of a specific omega-3 fatty acid, docosahexaenoic acid (DHA), which has been shown to "turn off" fat genes in the abdomen, preventing belly fat cells from growing larger. To keep calories to a minimum, skip the mayo and instead add a few cranks of ground pepper, a splash of balsamic vinegar and serve the fish over a bed of greens—super filling, yet low-cal.
If you're craving something sweet and sinful, grab this mini pack of jelly beans. With just 4 calories in each bean, they're the slimmest way to enjoy cotton candy, toasted marshmallows, and strawberry shortcake. As an added bonus: Jelly Belly uses real fruit purees to flavor their beans. It's still candy in every sense, but it's certainly the lesser of many sugar-loaded evils.
