With a caffeine count higher than coffee, these teas kick your metabolism into gear. In a study published in the journal *Physiology & Behavior*, a 3-4 percent increase in metabolic rate was measured in both lean and obese subjects after a single 100 mg dose of caffeine. Look for teas made from this caffeine-containing fruit; if you want to skip comparative shopping, just grab a box of Celestial Seasonings' Fast Lane, which clocks in 20 mg above your daily cup of coffee at 110 mg caffeine.

Don’t let extra hours lounging in bed stand between you and a flatter belly. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
The Paleo and ketogenic diets are related, with an emphasis on cutting carbs while increasing protein and fat. With Paleo, dieters eat “like cavemen,” sticking with fruits, vegetables, and meat while steering clear of grains and processed foods. On the other hand, the ketogenic diet involves paying close attention to macronutrients: carbs, fat, and protein. The idea is that by limiting carbs while eating foods high in fat and moderate in protein, the body is forced to burn fat instead of sugars.

Grains get a bad rap when it comes to weight loss, but that's because refined grains (read: processed foods!) are linked to wider waists. 100% whole grains are bloat-busting superstars, however, as they're packed with minerals and de-puff by counter-balancing salt. Stick to brown rice, quinoa, wheat, barley, millet, farro, sorghum, and amaranth for the biggest benefits.
"If your diet consists of lots of sports drinks, sugar-sweetened drinks like fizzy pop and flavoured waters, or sugary foods like chocolate and cakes, it will make losing weight harder. While whole fruits and vegetables are undoubtedly good for you, they can also sometimes cause weight gain if you eat too much, as they have high levels of natural sugars in them. Low-fat food options might have high amounts of added sugar in there too, so make sure to check the food label.
