1. Change your metabolism
Fat doesn’t make us fat, he says. Rather, sugars and carbs do that by triggering a flood of insulin, a hormone that turns fat cells on and off. High insulin levels in the blood stream tell fat cells to pile on fat and store it. Lowering your insulin lets your fat cells release fat, suppressing appetite and cravings and shedding body fat.
Sugar can trigger addictive responses, Ludwig says. It hijacks the brain’s pleasure and reward systems, producing intense, addiction-like cravings. Potatoes and highly processed carbohydrates such as white bread and pasta and refined cereals and snack foods have similar effects: They digest quickly into sugar, raising insulin, calorie for calorie, more than any other food.
Ludwig’s research lab scanned the brains of overweight young men four hours after they’d drunk milkshakes sweetened with corn syrup and found that the drinks activated their nucleus accumbens, the brain center stimulated by addictive substances like heroin, cocaine and alcohol.
To loosen sugar’s grip, Ludwig advises replacing it and high-carb foods with fats to satisfy hunger and quell cravings. Get the fat from nuts, seeds, nut butters, avocados, unsaturated oils, whole-fat (unsweetened) dairy products and — for a treat — dark chocolate that’s at least 70 percent cacao (or cocoa, which is cacao in its roasted, ground form).
Saturated fat raises the body’s LDL (“bad”) cholesterol, Ludwig acknowledges. However, “it also potently raises HDL (‘good’) cholesterol, so the all-important overall ratio of bad to good cholesterol remains largely unchanged. And unlike carbohydrate, saturated fat lowers triglycerides, another important risk factor.”
2. Avoid trans fat
Stay away from even small amounts of one type of fat: trans fat. Read labels and avoid foods with “partially hydrogenated oil,” an industrial oil made by adding hydrogen to liquid vegetable oil to make it harden. It’s common in fast food, fried food and commercially made cakes, cookies, crackers and snacks, including some microwave popcorn. Even small amounts add up, so try to avoid eating it at all.

3. Avoid artificial sweeteners
Artificial sweeteners make it hard to quit sugar as they keep your sweet tooth active, depriving you of the chance to let go the cycle of cravings and taste the subtler natural sweetness of fruits and vegetables. Try cinnamon, nutmeg and allspice to highlight sweetness in some fruits, tubers, squashes and even meats.
4. Avoid low-fat and nonfat foods
When food manufacturers take out the fat they typically add sugar. One example:
Jif Reduced Fat Creamy Peanut Butter Spread has 12 grams of fat and 4 grams of sugar.
Jif Regular Peanut Butter has 16 grams of fat and 3 grams of sugar
Exercise alone has been largely discredited as a weight-loss tool. “Physical activity is crucially important for improving overall health and fitness levels, but there is limited evidence to suggest that it can blunt the surge in obesity,” says the International Journal of Epidemiology, and researchers found that members of a hunter-gatherer tribe burn roughly as many calories as the typical city dweller despite their vastly different levels of activity, according to a report in the New York Times.
But there are many other reasons to move, among them reducing the risk of diabetes, heart disease and cancer. Exercise boosts your sense of vitality and vigor. It replenishes your sense of well-being and pride.
6. Get enough quality sleep
When you’re weary and pushing too hard you’re vulnerable to setbacks and emotional eating. Treat yourself with special care and give yourself credit when you’re giving up the undeniable pleasure of sugar. Take a warm bath before bed, read a good book, indulge in a cup of (unsweetened) herbal tea, get a massage and get plenty of healing rest.
