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.
“The alkaline diet often has a focus on eating lots of fresh produce and unprocessed foods, which could be a good thing,” says Hultin. “However, keep in mind that this is not an evidence-based therapeutic diet. When people take it too far — for instance, drinking baking soda — or become too restrictive or obsessive over food choices, it can definitely turn negative.”
Second, take a few photos of yourself to keep your motivation up. "Most of the people who come to me are doing it for a reason," he explains. "They're going on vacation, competing in a bodybuilding show, or maybe going to a reunion. I always have them strive for that goal. I take front, side, and back pictures of them at the beginning and have them post the photos on their mirror at home. I tell them, just keep looking at that picture and think of what you're going to look like in a few weeks."
Lastly, consider how the diet plan can be incorporated into your lifestyle and whether it’s sustainable for you over the long-term. Most weight loss fails because of the dieter’s inability to maintain their commitment. Price, time requirements for meal planning and preparation, satisfaction and flexibility with your lifestyle are therefore essential to your success, no matter which diet plan you choose.

If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.
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.
Most low-carb diets advocate replacing carbs with protein and fat, which could have some negative long-term effects on your health. If you do try a low-carb diet, you can reduce your risks and limit your intake of saturated and trans fats by choosing lean meats, fish and vegetarian sources of protein, low-fat dairy products, and eating plenty of leafy green and non-starchy vegetables.
Grilling coaxes sweet-savory depth from endive and red onion in this delicious vegetarian side dish. Fresh figs lend a bright, jammy acidity in the summer, but don't hesitate to use dried come winter. Leave the root ends attached when trimming your onions and endive, so they hold together and don't slip through the grill grates. Serve as a salad, or eat alongside grilled chicken, steak, salmon, seared scallops or whole roasted fish.
Before you start the meal plan, make a pot of the Veggie Soup. Make 2 servings of Overnight Oats, so they can soak in the fridge. It’s also super helpful to prep your veggie snacks—make 4 bags filled with baby carrots and sugar snap peas, and 3 bags filled with broccoli and cauliflower, for alternate days. And if you really want to get ahead, you could also grill the chicken breasts and cook the quinoa and brown rice in advance.
