The leafy green is jam-packed with energy-boosting nutrients such as vitamin A, iron, and folate. It can also reduce your appetite—helping to curb your calorie intake and encourage your body to start burning fat—thanks to natural compounds called thylakoids. Swedish researchers found that over three months, women who consumed a five-gram thylakoid supplement from spinach reported a 25 percent reduction in hunger and cravings and significantly more weight loss (11 pounds) than the control group!
This ancient grain will make that flat tire around your waist history! Quinoa is a complete protein, meaning that it contains the complete chain of amino acids that are necessary for muscle building and fat loss. In a 2015 study in the Journal of Diabetes Investigation, researchers discovered that patients who ingested higher amounts of vegetable protein were far less susceptible to metabolic syndrome (a combination of high cholesterol, high blood sugar, and obesity). Before you thought it couldn’t get any better, there’s more: quinoa has the highest level of betaine, according to a Food Chemistry study. Why is that important? Well, a Nutrients study linked betaine supplementation to a revved metabolism and inhibition of fat production.
If you don’t have an established exercise routine, simply walking is the best first step toward weight loss. “Walking is a pretty good entry point for people,” says Gagliardi. This is particularly true if you have been out of the gym for a while and want to ease back into a workout routine. One small study published in The Journal of Exercise Nutrition & Biochemistry found that obese women who did a walking program for 50 to 70 minutes three days per week for 12 weeks significantly slashed their visceral fat compared to a sedentary control group.
A longtime enemy of doctors and dieters, pork has been coming around as a healthier alternative of late–as long as you choose the right cut. Your best bet is pork tenderloin. A three-ounce serving of pork tenderloin has slightly less fat than a skinless chicken breast; It has 24 grams of protein per serving and 83 milligrams of choline. In a study published in the journal Nutrients, scientists asked 144 overweight people to eat a diet rich in fresh lean pork. After three months, the group saw a significant reduction in waist size, BMI and belly fat, with no reduction in muscle mass! They speculate that the amino acid profile of pork protein may contribute to greater fat burning.
Sure, ketchup is tasty, but it’s also a serious saboteur when it comes your weight loss efforts. Ketchup is loaded with sugar — up to four grams per tablespoon — and bears little nutritional resemblance to the fruit from which it’s derived. Luckily, swapping out your ketchup for salsa can help you shave off that belly fat at home without a diet. Fresh tomatoes, like those used in salsa, are loaded with lycopene, which a study conducted at China Medical University in Taiwan links to reductions in both overall fat and waist circumference. If you like your salsa spicy, all the better; the capsaicin in hot peppers, like jalapeños and chipotles, can boost your metabolism, too.
“For some people, it’s knowing, ‘Typically I eat a whole sandwich,’” says Gagliardi. “‘Now, I’m going to make the decision to eat half a sandwich at lunch and save the other half for my dinner and essentially cut my calories in half. And they feel good about that. They’re not having to do math.” To get started, check out these 25 simple ways to cut 500 calories a day.
This classic lunchbox sandwich condiment is teeming with flat-belly nutrients such as cholesterol-lowering monounsaturated fats and is a great source of plant-based protein. According to a recent study presented at the annual Society for Endocrinology conference, researchers found that when protein is digested and broken down into amino acids in your body, one of those amino acids—phenylalanine—triggers hormones that help reduce appetite and ultimately leads to fat burn and weight loss.
