Although their efficacy and safety are constantly scrutinized by the FDA and other organizations, manufacturers of thermogenic “diet pills” often claim that taking these supplements can help improve weight loss almost effortlessly by boosting your metabolism (the rate at which you burn calories). Some may also be at least somewhat helpful for decreasing your appetite, curbing cravings for junk foods and giving you more energy, which can be used for physical activity.
Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time without exercise. Berries are loaded with antioxidants, which can help reduce inflammation throughout the body, and research from the University of Michigan reveals that rats given a cherry-rich diet shaved off a significant proportion of their belly fat when compared to a control group. Berries like strawberries, raspberries, blueberries, and blackberries are also loaded with resveratrol, an antioxidant pigment that has been linked to reductions in belly fat and a reduced risk of dementia, to boot.
Those trans fats on your menu are hiding out in plain sight and sabotaging your lean belly plans every time you eat them. If a food product says it contains partially hydrogenated oils, you're eating trans fat, which can increase your risk of heart disease, high cholesterol, and obesity with every bite. In fact, research conducted at Wake Forest University reveals that monkeys whose diets contained eight percent trans fat upped their body fat by 7.2 percent over a six-year study, while those who ate monounsaturated fat gained just a fraction of that amount. Instead of letting harmful trans fat take up space on your menu, fill up with these healthy fats.
The researchers explain that people who cook their own meals may simply have other good-for-you habits, like exercising more. However, they also concluded that home cooks ate more fruits and vegetables (along with a wider variety of foods), have healthier methods of prepping their food, and splurge less on foods high in calories and sugar. Consider any of the healthy eating books below to get started.
Some cheat meals are better than others. And a high-carbohydrate, moderate-protein meal, however "naughty," can help you stay on track. The reason: Carbohydrates have the greatest influence on leptin levels, which help you burn fat and feel satisfied. And protein has the greatest influence on satiety because of its influence on appetite-regulating hormones and high thermic effect—the process of digesting protein requires more energy of your body than any other macronutrient. So, go ahead and grab a bowl of spaghetti and meatballs. Contrary to popular belief, pasta is actually a fairly low-glycemic food, meaning it won't drastically spike your blood sugar levels.
There’s a key difference between how supplements are regulated versus how medications or other drugs are. Dietary supplements are considered safe until proven unsafe, while the opposite is true of prescription drugs: They’re kept out of the public’s hands until clinical trials show they’re generally effective and also unharmful to the majority of patients taking them.
Research also finds that drinking frequently—even if it’s a moderate amount—can set you up for excess pudge. Not only do the beverages themselves contain unnecessary calories, but once you start sipping too much, your inhibition also plummets, according to one 2016 study. The result? You’ll have a hard time resisting that late-night slice of pizza. So if you're going to imbibe, stick to one drink per day for women and up to two drinks for men. (Order one of these lowest-calorie alcoholic drinks.)
One thing a fat burner won't do, however, is fix a broken diet. If you're eating for healthy fat loss, the way Krissy Kendall, Ph.D., explains in the comprehensive guide "How to Lose Weight," then a thermogenic fat burner can help with the other stuff: boosting energy, helping to curb appetite, promoting fat to be used for energy, and even increasing your metabolism and core temperature—what is known as "thermogenesis"—so you burn more calories throughout the day.
Each slice of grapefruit you add to your salad acts like a match to spark your body's fat-burning ability. A study published in the journal Metabolism found that those who ate grapefruit for six weeks lost a full inch off their waistlines. What's behind the belt-tightening effect? The fruit is rich in phytochemicals, bioactive compounds that recent research shows stimulate the production of a hormone called adiponectin, which is involved in the breakdown of body fat. Japanese research suggests the smell of the juicy fruit can "turn on" calorie-burning brown fat cells, promoting the breakdown of body fat while reducing appetite.
This Asian veggie dish is made by fermenting a blend of cabbage, radishes, and scallions with a seasoned paste of red pepper, salted shrimp, or kelp (koji) powder. Fermented foods are great for healing your gut thanks to the high levels of probiotics, but the unique strains found in kimchi may also help you stay slim: Researchers at Kyung Hee University in Korea induced obesity in lab rats by feeding them a high-fat diet. The group that got a Lactobacillus brevis supplement— the culture strain found in kimchi—was able to suppress the diet-induced increase in weight gain by 28 percent! If kimchi isn't your thing, also consider adding one of these probiotic foods for a healthier gut to your diet.
