Ultimately, you need to pick a healthy eating plan you can stick to, Stewart says. The benefit of a low-carb approach is that it simply involves learning better food choices—no calorie-counting is necessary. In general, a low-carb way of eating shifts your intake away from problem foods—those high in carbs and sugar and without much fiber, like bread, bagels and sodas—and toward high-fiber or high-protein choices, like vegetables, beans and healthy meats.
Don’t work out later than three days before your event. If your party’s on Saturday, for example, do your last workout of the week on Wednesday—muscles bulge most when they’re flush with glycogen (the carbohydrates stored in muscle), so you need to give your body time to recover and replenish its glycogen stores before your unveiling. If you train too close to the big day, the carbs stored in your muscles will be depleted, and you’ll end up looking flat and soft. Furthermore, make sure this last workout focuses on the areas you want to highlight, such as chest and arms. Glycogen is replenished fastest in muscles that need it most—i.e., the ones that have just been worked—so if you want your pecs and biceps to pop, you have to make sure they soak up as many of the carbs you’re taking in as possible (explained in the next step).
The popular "flat belly diets"embrace much of the wisdom found in eating a Mediterranean diet, which helps everything from brain health to hearth health. The basic premise for both diets is eat foods rich in monosaturated fatty acids (MUFA) that may help reduce your belly fat storage. MUFA-rich foods include olive oil, nuts and seeds, avocodos, and fish. Eating yogurt regularly has also been found to be helpful in reducing belly fat.
