Even if you do meet your goal, it's nearly impossible to keep off the weight over the long term: "The amount of restriction required [to maintain that number] will make you so hungry that you’ll eat everything in sight—it’s survival instinct," Dr. Seltzer says. And since calorie restriction gradually slows your metabolism, your body will be less prepared to burn the foods you binge on, he adds. That could mean gaining more pounds than you lost in the first place.
Clinical nutritionist Stephanie Moore says intermittent fasting could be a great way to challenge the body to burn more fat and maintain muscle. Some studies have also found that regular short-term fasts could boost metabolism by 3.6 to 14 percent. Intermittent fasting is a convenient way to restrict calories without consciously trying to eat less. Many studies show that it is an effective weight loss strategy if people don’t overcompensate calorie-wise with their meals. Here are nutritionist-approved ways to speed up your metabolism.
Dairy products contain varying amounts of lactose (milk sugar), which slows down weight loss. What’s more, part of the protein in milk generates a significant insulin response, which can have the same effect. Consequently, cutting back on dairy products may accelerate weight loss. This applies especially to dairy products typically lacking in fat, such as regular milk and various yogurts, but be careful with full-fat dairy such as cream and cheese all the same. And don’t forget whey protein powder, which is pure milk protein.
Consequently, researchers have widely discredited the hCG diet, which involves using hCG injections, pellets, sprays, or drops, and consuming as few as 500 calories daily. The diet is problematic not only because there’s a lack of research on hCG supplements, but also because the calorie requirement is dangerously low, potentially leading to nutrient deficiencies, fatigue, hormone imbalances, blood clots, and other issues. Thus, most experts agree the hCG diet is not safe for anyone, the Mayo Clinic notes. (35)
You may be tempted to skip meals like breakfast when you're trying to lose an extreme amount of weight, but those who succeed at weight loss make breakfast a priority. Try a poached egg on a slice of whole-wheat toast covered in one-eighth of an avocado and served with 1 cup of sliced strawberries and a 6-ounce container of nonfat Greek yogurt for 420 calories. A 1/2-cup serving of low-fat cottage cheese with a sliced banana and an English muffin with 2 teaspoons of peanut butter also makes a good breakfast option on your weight-loss diet. That option contains 440 calories. Or enjoy a breakfast smoothie by blending 12 ounces of nonfat Greek yogurt with 2 tablespoons of ground flaxseeds, 3/4 cup of blueberries, 1 cup of raspberries and ice for 400 calories.
The plan laid out in the book Flat Belly Diet! says you will lose up to 15 pounds in 32 days. The first phase offers an initial anti-bloat plan, followed by four weeks of strict eating that incorporates healthy monounsaturated fats at every meal. While the diet has no research to support it, the plan is loosely based loosely on the Mediterranean diet, which is highly backed by research.
To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
The Mayo Clinic health experts designed this plan to produce long-lasting behavior change—and lasting weight loss. You can lose six to ten pounds in the Lose It phase by adding healthy habits and ditching unhealthy ones. Food choices are built around the Mayo Clinic Healthy Weight Pyramid and bulky, low-calorie foods that fill you up fast—an idea that scores well in studies. The Live It phase teaches more advanced weight-loss skills to help make it stick. This diet plan’s main restrictions are to eat out less, not expect overnight weight loss, and seek your healthcare professional’s approval before starting. Don’t miss these 13 weight-loss foods that will help you shed pounds fast.
The Centers for Disease Control and Prevention suggests subtracting 500 to 1,000 calories from your usual intake each day to lose at a healthy rate. First, keep a food diary to estimate the number of calories you currently eat, then subtract the calories to determine your weight-loss calorie needs. For example, if you currently eat 2,300 calories a day, to lose 1 to 2 pounds a week you need to reduce your intake to 1,800 calories or 1,300 calories a day, respectively.
Close the Kitchen at Night. Establish a time when you will stop eating so you won't give in to the late-night munchies or mindless snacking while watching television. "Have a cup of tea, suck on a piece of hard candy or enjoy a small bowl of light ice cream or frozen yogurt if you want something sweet after dinner, but then brush your teeth so you will be less likely to eat or drink anything else," suggests Elaine Magee, MPH, RD, WebMD's "Recipe Doctor" and the author of Comfort Food Makeovers.
