Despite the common perception that you need to drop pounds slowly in order to maintain your weight loss, the exact opposite is true. In fact, you’re more than five times as likely to succeed in your long-term weight-loss goals if you start out of the gate by dropping pounds rapidly, according to a 2010 study in the International Journal of Behavioral Medicine . To set yourself up for weight loss success, make sure you focus on diet and exercise.

Like a marathoner stretching before the big run, eating half a grapefruit before a meal can enhance your body’s fat-burning performance. A study published in the journal Metabolism found that this “warm-up” tactic can help whittle your middle—by up to an inch—in just six weeks! The scientists attribute the powerful effects to the grapefruits’ fat-zapping phytochemicals. The fruit can interact negatively with certain medications, so as long as you get the green-light from your M.D, plan to have half of a grapefruit before your morning meal and add a few segments your starter salads to reap the benefits.
The benefits of chowing down on whole fruits are clear, and eating an apple each day can help prevent metabolic syndrome, a disorder associated with abdominal fat, cardiovascular disease, and diabetes. The red or green fruits are a low-calorie, nutrient-dense source of fiber, which research has proven to be integral to reducing visceral fat. A study at Wake Forest Baptist Medical Center  found that for every 10-gram increase in soluble fiber eaten per day, visceral fat was reduced by 3.7 percent over five years.
By now, you probably know that coffee can help curb your appetite. But did you also know it can boost your metabolism? Since coffee contains the antioxidant chlorogenic acid (CGA), it can actually increase your body’s use of fat for energy. Research has additionally shown that CGA can slow the release of glucose and lower insulin resistance to inhibit weight gain after eating a meal.
Lately, we’re noticing protein-packed everything—from breads to nut butter and milk. While you don’t need to load up on weird franken-foods to amp up your intake of the nutrient, if you’re trying to drop a few pounds, then it’s wise to keep some high-protein snacks on hand. Noshing on these can prevent eating something high-calorie every time hunger strikes.
Salmon is a rich source of high-quality protein and provides plenty of "good" fats: omega-3 fatty acids. A diet rich in omega-3 fatty acids helped people feel more satisfied when they were watching their calories, per a study in Appetite. Eating salmon can be a delicious and versatile way to get your recommended two weekly servings of heart-healthy fish.
_{Healthy midnight snacks are OK, but try not to graze in the window of time between breakfast and lunch. A study published in the Journal of the American Dietetic Association found mid-morning snackers typically eat more over the course of a day than afternoon snackers. Furthermore, researchers found that dieters with the mid-morning munchies lost an average of 7 percent of their total body weight while those who did not snack before lunch lost more than 11 percent of their body weight.}

Calcium and vitamin C team up well to boost metabolism, and broccoli is just one of several healthy foods that contain both nutrients. What sets broccoli apart from the others, however, is that the green veggie also contains kind of fiber that’s been shown to increase the digestion, absorption and storage of food, also known as the thermic effect of food or TEF. Combine a revved up metabolism with an increased TEF and you get a match made in weight loss heaven!

The American Heart Association recommends that the amount of added sugar consumed in a day shouldn’t exceed 25 grams for women and 37.5 grams for men, but since the sweet stuff is in everything from bread to tomato sauce, most Americans aren’t adhering to those guidelines and they’re fatter for it. In a review of 68 clinical trials and studies, New Zealand researchers reported in the British Medical Journal that increasing sugar intake meant increasing body weight while reducing sugar meant reducing body weight. Additional research has shown that cutting back on the granular stuff is one of the fastest ways to lose weight.

Coconut oil may be high in saturated fat, but that doesn’t mean you should write it off completely, especially when it comes to weight loss. In fact, a study of 30 men published in Pharmacology found that just two tablespoons per day reduced waist circumference by an average of 1.1 inches over the course of a month. What’s more? At roughly 117 calories per tablespoon, coconut oil (which has a versatile high smoke point) is an ideal cooking companion so long as you don’t use it every day and rotate in other cooking oils such as heart-healthy EVOO.
