You’ll start each cardio day with Tabata-timed cardio. The HIIT protocol that follows calls for sprinting “on the minute,” meaning that your sprints and active rest will always add up to a minute. You’re free to choose your method of cardio, but treadmill running has been shown to burn more calories than cycling. In the first workout, perform 10 all-out 12-second sprints, with 48 seconds of active rest. This will amount to 120 seconds of total sprinting. The next time out, do more: 11 sprints at 13 seconds each, with active rest diminishing by a second. You can expect a similar uptick in volume each cardio session.
Want to lose that belly fat fast? In your dreams! Seriously, though: a good night’s sleep is one of the best ways to get rid of that extra fat around your waist for good. Among the 60,000 women participating in the Nurses’ Health Study, those who snoozed for fewer than five hours a night were at the greatest risk of becoming obese and gaining 30 or more pounds over the course of the 16-year study period when compared to those who slept for seven or more hours.
Regular exercise is key to weight loss and maintenance. And since there’s no consensus on whether the ideal workout is aerobic or resistance training, your best bet is to do a little of both. Resistance training is especially important for people over 30, who will otherwise begin to lose bone density. Contrary to popular belief, abdominal crunches are not going to melt away belly fat, though they will help build muscle that could help define the area. And since muscle mass has a higher resting metabolic rate and energy expenditure than fat, it could help you trim down. Mix up your workout routine with these exercises that flatten your belly—without a single crunch.

Avoid sweetened drinks. Drinks that are sweetened, whether artificially or naturally, will have little nutritional value and add lots of empty calories to your diet. Do not drink fruit juice or other sweetened drinks. Even natural sugars will increase your daily calorie intake and prevent weight loss. If you chose to drink juice, do not exceed 4 oz per day (1/2 cup). Instead of drinking sweetened beverages throughout your day, drink unsweetened, calorie-free beverages. Some beverages to avoid include:
In a way, moderate-intensity physical activity is that "magic pill" a lot of people are looking for, because the health benefits go beyond keeping your waistline trim: Not only can it reduce your risk of cancer, stroke, diabetes and heart attacks, but studies have shown that physical activity can significantly improve the moods of patients with major depressive disorders.
