Green tea extract: Of the most popular weight loss ingredients, this seems to be one of the safest. However, it’s not guaranteed to work well enough to really cause noticeable results. Reported adverse effects may include headache and urinary tract infections, although these are rare. Possible benefits include a mild increase in energy expenditure and fat oxidation.
One of the reasons your metabolism isn't burning away fat as efficiently as you'd like? Look to your magnesium levels. This essential micronutrient is required for the body to produce and store energy, and also helps boost lipolysis (a process by which your body releases fat from its stores to use as energy)—yet 75 percent of Americans do not get their RDA of this important metabolism-boosting mineral. Just a half cup of pumpkin seeds provides nearly 100 percent of your daily magnesium needs.
Fat burners have ingredients, such as caffeine and green tea, that act as a hunger suppressant. These help to ward off those cravings and decrease your overall hunger. Your body produces a hormone called leptin that is responsible for telling your body it is full and doesn’t need more food. This helps reduce the urge to overeat or snack throughout the day.
Kickstart your morning—and your metabolism—with this warming spice. Cinnamon contains powerful antioxidants called polyphenols that are proven to alter body composition and improve insulin sensitivity (which means it keeps blood sugar stable, preventing hunger-inducing spikes and crashes). Japanese researchers found that mice who ate a daily helping of cinnamaldehyde (the ingredient that gives cinnamon its flavor) lost belly fat, while those who skipped the spice did not. Add it to your overnight oats or sprinkle some in your coffee to reap the benefits.
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.
Spending more time in the kitchen can help you shed belly fat, as long as you’re cooking with the right foods, according to a 2017 study. After analyzing data from more than 11,000 men and women, U.K. researchers found that people who ate more than five homemade meals per week were 28 percent less likely to have a high body mass index, and 24 percent less likely to carry too much body fat than those whole only downed three meals at home.
