Everyone wants a flatter belly, especially when warmer weather dictates lighter clothing. When it comes time to hit the beach or pool, will you be ready to dive in? To even head in the direction of belly-baring status, you must first know thine enemy – your abdominal fat. Afterward, read on to see what you can do to help chisel a trimmer tummy.
How to measure your Waist-to-Hip ratio (either metric or customary):
1) Standing relaxed, with a flexible tape, measure waist at smallest area – or if this is not apparent, mid-way between the lowest rib and top of hip bone.
2) With feet and thighs together, measure hips at the widest portion of your buttock.
3) Divide waist measurement by hip measurement to get your ratio. The ratio should be less than 0.9 for men; less than 0.85 for women.
No matter your current physique, the following approaches may help you achieve obtaining a flatter belly.
Greater physical activity is associated with lower waist circumference and waist-to-hip ratio. It’s no secret that moving muscles are the furnace for fat burning. Exercise is really essential in fat metabolism. Exercise burns fatty acids (in processes called lipolysis and oxidation), contributing to reduction in body fat. Aside from exercise aiding in fat-burning, a developing theory is that fat cells, including those in the abdomen, are temporarily ‘starved’ when blood flow is focused to moving muscles.
True, you can’t spot reduce, selectively dropping fat from only one area of the body. But new research indicates that certain types of exercise can reduce belly fat more than others. While the same level of calories are burned with each, anaerobic high-intensity intermittent training has been shown to produce greater abdominal fat reduction than continuous aerobic training.1
Calorie restriction (regardless of energy source) affects both visceral fat and subcutaneous fat. This is only true to an extent, as very low calorie diets end up with the losses of visceral fat regained weeks afterward. In fact, modest weight loss, even 5% body weight for overweight individuals, is enough to reduce visceral fat, regardless of method. One study showed that 4 different calorie-reduced diets were equally effective in reducing abdominal fat, with most loss coming from subcutaneous fat.2
A greater intake of fat and carbohydrates, typical of Western diets, is associated with higher waist circumference. Conversely, those following a Mediterranean style diet were less likely to gain abdominal fat over 10 years.3 This style reflects a focus on plant-based foods (like vegetables, fruit, and whole grains) with moderate protein intake, minimal animal fats, and a prominence of olive oil, all resulting in a low saturated fat intake. The bulk of research indicates conventional nutritionally-balanced plans are as effective as high protein diets in reducing abdominal fat.
Green tea (vs. black) is made with the youngest leaves, which have the most catechins. See our related article – Nutrition is Sprouting this Spring!
At a certain threshold, catechin compounds in green tea can impact abdominal fat. These compounds (prominently ECGC) may have affect the sympathetic nervous system in a way that influences fat distribution. It takes about the equivalent of 5 cups of tea, or 500 mg catechins, for an effect. Studies with significant finding used catechin-enhanced beverages.4,5 More is not better… consuming >800 mg ECGC in one sitting would be like slamming a gallon of green tea all at once, and instead of acting as an antioxidant (as it does at lower levels), you’d get pro-oxidant effects! Also, having smaller servings spread throughout the day is more effective than a single huge dose.
For the most catechins, look for quality packaging to ensure better storage with minimal exposure to oxygen, light and moisture. Also, don’t take highly concentrated EGCG green tea extracts or supplements while taking acetaminophen.
Though it won’t change your belly fat, adjusting your posture could improve the appearance of your midsection. Tilt your pelvis when standing so that your tailbone is in (pointed down, not out), as shown to the right.
