They should help keep you from feeling deprived and bingeing on higher-calorie foods. For instance: honey has just 64 fat-releasing calories in one tablespoon. Eggs have just 70 calories in one hard-boiled egg, loaded with fat-releasing protein. Part-skim ricotta cheese has just 39 calories in one ounce, packed with fat-releasing calcium. Dark chocolate has about 168 calories in a one-ounce square, but it’s packed with fat releasers. And a University of Tennessee study found that people who cut 500 calories a day and ate yogurt three times a day for 12 weeks lost more weight and body fat than a group that only cut the calories. The researchers concluded that the calcium in low-fat dairy foods triggers a hormonal response that inhibits the body’s production of fat cells and boosts the breakdown of fat.
People with chronically high levels of the stress hormone cortisol tend to carry excess visceral fat. Foods that are high on the glycemic index (GI), which uses a ranking system of 0 to 100, cause more rapid spikes in your blood sugar, in turn triggering the release of cortisol when glucose levels crash. The constant up and down of your blood sugar levels can also lead to insulin resistance — the first step on the road to type 2 diabetes. To help keep cortisol levels stable, choose low-GI foods (with a rating of 55 or less) like beans, lentils, and chickpeas, instead of high-GI options like white rice and potatoes. To find the GI rating of your foods, use the University of Sydney’s database at glycemicindex.com.
The conclusion? Intermittent fasting was just as effective for weight loss as daily calorie restriction. So if you struggle with daily food restriction, fasting might be an easier way to dial back the amount you’re eating without feeling completely deprived. Read more in-depth about how intermittent fasting works (and if you’ll be able to stick to it) here.
This just in: Saturated fat packs on more visceral fat than polyunsaturated ones, according to a recent Swedish study. When subjects ate 750 more calories daily for seven weeks—either in the form of palm oil (saturated) or sunflower oil (polyunsaturated)—the former gained more visceral fat while the latter gained more muscle mass and less body fat. Polyunsaturated fats can be found in nuts, seeds, and fish.
Having a larger waist circumference is a better indicator of health problems than commonly used measurements like body-mass index (BMI), according to a growing body of research. Specifically, having a waist size higher than 40 inches around for men or 34.5 inches for women is correlated with a higher risk for developing type 2 diabetes and heart attack. There's even evidence that having more belly fat is correlated with lower cognitive performance.
Do you even lift, bro? If you’re serious about getting rid of that belly fat fast, resistance training might just be the key. A study from the Harvard School of Public Health found that adding weight training to adult male test subjects’ workouts significantly reduced their risk of abdominal obesity over a multi-year study period, although doing the same amount of cardio had no such effect. Research from the University of Maryland even found that just 16 weeks of weight training boosted study participants’ metabolic rates by a whopping 7.7 percent, making it easier to ditch those extra inches around your middle.
