1. Don’t Diet!
The Men’s Health Diet isn’t about eating less, it’s about eating more—more nutrition-dense food, to crowd out the empty calories and keep you full all day. That’s important, because restricting food will kill your metabolism. It makes your body think, “I’m starving here!” And your body responds by slowing your metabolic rate in order to hold on to existing energy stores. What’s worse, if the food shortage (meaning your crash diet) continues, you’ll begin burning muscle tissue, which just gives your enemy, visceral fat, a greater advantage. Your metabolism drops even more, and fat goes on to claim even more territory.
2. Go to Bed Earlier
A study in Finland looked at sets of identical twins and discovered that of each set of siblings, the twin who slept less and was under more stress had more visceral fat.
3. Eat More Protein
Your body needs protein to maintain lean muscle. In a 2006 study in the American Journal of Clinical Nutrition, “The Underappreciated Role of Muscle in Health and Disease,” researchers argued that the present recommended daily allowance of protein, 0.36 grams per pound of body weight, was established using obsolete data and is woefully inadequate for an individual doing resistance training. Researchers now recommend an amount between 0.8 and one gram per pound of body weight. Add a serving, like three ounces of lean meat, two tablespoons of nuts, or eight ounces of low-fat yogurt, to every meal and snack. Plus, research showed that protein can up post-meal calorie burn by as much as 35 percent.
4. Go Organic When You Can
Canadian researchers reported that dieters with the most organochlorines (pollutants from pesticides, which are stored in fat cells) experienced a greater than normal dip in metabolism as they lost weight, perhaps because the toxins interfere with the energy-burning process. In other words, pesticides make it harder to lose pounds. Other research hints that pesticides can trigger weight gain. Of course, it’s not always easy to find—or to afford—a whole bunch of organic produce. So you need to know when organic counts, and when it’s not that important. Organic onions, avocados, grapefruit? Not necessary. But choose organic when buying celery, peaches, strawberries, apples, blueberries, nectarines, bell peppers, spinach, kale or collard greens, cherries, potatoes, and imported grapes; they tend to have the highest levels of pesticides. A simple rule of thumb: If you can eat the skin, go organic.
5. Get Up, Stand Up
Whether you sit or stand at work may play as big a role in your health and your waistline as your fitness routine. In one study researchers discovered that inactivity (four hours or more) causes a near shutdown in an enzyme that controls fat and cholesterol metabolism. To keep this enzyme active and increase your fat burning, break up long periods of downtime by standing up—for example, while talking on the phone.
6. Drink Cold Water
German researchers found that drinking 6 cups of cold water a day (that’s 48 ounces) can raise resting metabolism by about 50 calories daily—enough to shed five pounds in a year. The increase may come from the work it takes to heat the water to body temperature. Though the extra calories you burn drinking a single glass don’t amount to much, making it a habit can add up to pounds lost with essentially zero additional effort.
7. Eat the Heat
It turns out that capsaicin, the compound that gives chili peppers their mouth-searing quality, can also fire up your metabolism. Eating about one tablespoon of chopped red or green chilies boosts your body’s production of heat and the activity of your sympathetic nervous system (responsible for our fight-or-flight response), according to a study published in the Journal of Nutritional Science and Vitaminology. The result: a temporary metabolism spike of about 23 percent. Stock up on chilies to add to meals, and keep a jar of red pepper flakes on hand for topping pizzas, pastas, and stir-fries.
8. Rev Up in the Morning
Eating breakfast jump-starts metabolism and keeps energy high all day. It’s no accident that those who skip this meal are 4 1/2 times as likely to be obese. And the heartier your first meal is, the better. In one study published by the American Journal of Epidemiology, volunteers who got 22 to 55 percent of their total calories at breakfast gained only 1.7 pounds on average over four years. Those who ate zero to 11 percent of their calories in the morning gained nearly 3 pounds.
9. Drink Coffee or Tea
Caffeine is a central nervous system stimulant, so your daily java jolt can rev your metabolism 5 to 8 percent—about 98 to 174 calories a day. A cup of brewed tea can raise your metabolism by 12 percent, according to one Japanese study. Researchers believe the antioxidant catechins in tea provide the boost.
10. Fight Fat With Fiber
Fiber can rev your fat burn by as much as 30 percent. Studies find that those who eat the most fiber gain the least weight over time. Aim for about 25 grams a day—the amount in about three servings each of fruits and vegetables.
