While the most exact way to measure visceral fat is by MRI or CT scan, an at-home approach is to calculate the waist-to-hip ratio by dividing the waist measurement by the hip measurement. For example, if the waist measures 56 inches and the hips measure 45 inches, dividing 45 into 56 gives a ratio of 1.2. A waist-to-hip ratio higher than 0.95 in men and 0.85 in women significantly increases the risk of a heart attack or stroke. Simply measure the waist to identify if there is a higher probability of excess visceral fat. In men, a waist measurement over 40 inches (and in women, a waist measurement over 35) indicates an unhealthy accumulation of visceral fat and an increased risk of health problems.
Your lower belly fat may also be a result of sedentary behaviors. If you aren't burning the calories you consume, the excess accumulates in your belly. Getting more active, such as working up to 150 minutes -- or longer -- of moderate-intensity cardiovascular activity per week helps. You'll also benefit from being active all day long with small movements such as fidgeting and pacing.
Most detox teas contain caffeine, probably because this stimulant may suppress appetite, trigger your digestive system to let go of waste, and help you shed water weight. A caffeine-induced energy boost may also lead to working out a little longer or harder than usual. However, too much caffeine can also be risky (see above) and interfere with getting enough sleep–and catching too few zzzs may ultimately undo the tea's weight-loss effects. In fact, too little shuteye has been shown to trigger excessive eating and weight gain and even slow metabolism, which can make it easier to gain weight even if you don't eat extra calories. A good rule of thumb, regardless of where your caffeine is coming from, is to nix it at least six hours before bed. And if you're trying to shed pounds, commit to making adequate sleep a top priority.
In men, adequate levels of testosterone are necessary to maintain a healthy fat distribution. However, research has shown that the presence of visceral fat can interfere with testosterone production, further exacerbating the storage of fat in the belly. Excess abdominal fat not only reduces testosterone production, but is also associated with a rise in the female hormone estradiol in men. It is unclear if testosterone decline associated with aging disrupts the production of testosterone, or if the accumulation of fat via weight gain leads to lower levels of testosterone. Either way, the reduction of visceral fat via lifestyle changes is beneficial for overall health in men.
This is the result of a lazy thyroid, the gland being responsible for producing hormones that control the metabolism. A lower metabolism is surely a trigger for weight gain, but it’s not just the excess belly fat that gives headaches to this group of people: they also tend to have poor circulation and cold extremities, hair loss, saggy underarm skin and brittle fingernails.
