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.
Based on my experience in nutrition counseling, most of us tend to snack on foods that aren’t nutrient-dense, but are high in calories. For example, skipping sugary beverages is often the easiest way to lose weight faster. You don’t feel full from drinks — even the ones that do contain calories — so swapping those out for sparkling water or unsweetened tea and coffee is the best place to start. Other major culprits often come in refined grains like cereals, chips, crackers, and cookies.

"The best thing you can do for your belly is to give up processed foods. A study in the journal Food & Nutrition Research found that our bodies burn only 50 percent as many calories digesting processed foods as they do real foods. So it's like eating twice as much, even if the calories are the same!" — Mark Langowski, celebrity trainer, CEO and Founder of Body By Mark 


"A study published in Nutrition Journal found that participants who ate foods high in monounsaturated fats for lunch (in this case, half an avocado) reported a 40 percent decreased desire to eat for hours afterward. Monounsaturated fats from sources like olive oil, nuts and avocados can reduce cholesterol, promote weight loss, even boost memory." — David Zinczenko, author of the Zero Belly Cookbook
"Don't buy low-fat dairy products. They're usually loaded with sugar. Besides, an American Journal of Clinical Nutrition study found that the more high-fat dairy products a person ate, they lower their risk of diabetes; the more low-fat dairy products, the higher their risk. — Mark Langowski, celebrity trainer and author of Eat This, Not That! for Abs
"Burpees are such a great way to activate multiple muscles, get the heart rate up and burn mega calories. In one single burpee, you work your legs, arms and abs and you also elevate the heart rate to increase cardiopulmonary strength. If you're looking to lose weight, incorporating them into your workout routine is a must."—Kit Rich, celebrity trainer and co-owner of SHIFT by Dana Perri
"There are many foods that aid weight loss, but one that I often recommend to my clients and eat myself is grapefruit. Researchers at Scripps Clinic in San Diego found that when obese people ate half a grapefruit before each meal, they dropped an average of 3.5 pounds over 12 weeks. Apparently, the tangy fruit can lower insulin, a fat-storage hormone, and that can lead to weight loss. Plus, since it's at least 90% water, it can fill you up so you eat less. However, if you are on certain medications you should not have grapefruit or grapefruit juice, so check the label on all your prescriptions, or ask your pharmacist or doctor." — Patricia Bannan, MS, RDN, author of Eat Right When Time is Tight.
"One of the keys to long-term and sustainable weight loss is to cut total calorie intake, and there's no better way to do that than by eating just a little bit less of what you currently eat. Once you get into a habit of reducing portions—especially of sugary, fatty and other nutrient-poor foods—you can fine tune your diet to incorporate more nutrient-rich foods. But paring portions is still the best first step [in an effort to lose 10 pounds]." — Elisa Zied, MS, RDN, CDN, author of Younger Next Week
"It's far more difficult to eat a healthier diet and fit in exercise if you don't plan ahead. Plan out your meals for the week ahead and go grocery shopping over the weekend to ensure you have the ingredients you need on hand. If you can, do some meal prep in your downtime—cut fresh veggies, marinate your protein, cook up a batch of whole grains in advance. When you're prepared you're far less likely to order takeout. — Jessica Fishman Levinson, MS, RDN, CDN, culinary-nutrition consultant and founder of Nutritioulicious
"If weight loss is the goal, I recommend learning how to properly deadlift. Deadlifting recruits more muscle fiber at once than any other exercise. More muscle working equates to more blood flow, an increased heart rate, more metabolic demand and output. It's compound, multi-joint and more bang for your buck, not to mention you'll develop an excellent posterior from them." — Victoria Viola, PN Certified Nutrition Coach, NSCA CPT, Co-Founder, Excelerate Wellness, LLC
It's a one-time investment you'll never regret. Here's why: Strength training builds lean muscle tissue, which burns more calories — at work or at rest — 24 hours a day, seven days a week. The more lean muscle you have, the faster you'll slim down. How do you start strength training? Try some push-ups or a few squats or lunges. Use your free weights to perform simple bicep curls or tricep pulls right in your home or office. Do these exercises three to four times per week, and you'll soon see a rapid improvement.

What if we told you that you could make 20 percent of your belly disappear this year—poof, just gone? Penn State University researchers compared those who consumed avocado oil with those who consumed a flax-safflower oil blend. Those on the canola oil diet—just three tablespoons daily did the trick—lost nearly 2 percent of their belly fat in just one month. For more ways to enjoy big, bold flavors, burn flab with these healthy fats.
