Detox teas that combine caffeine with diuretics can trigger the loss of water weight. Just two cups of water weighs one pound on a scale, so shedding fluid can make you look and feel lighter–even if you haven't lost an ounce of body fat. Detox teas can also trigger a laxative effect, which causes your body to eliminate waste from your GI tract, another result that can make your stomach flatter, and allow you to feel lighter, even if your lean-to-fat ratio remains exactly the same. If this quick-fix effect gives you the confidence boost and motivation you need to start eating healthier and working out–the real keys to getting healthy and lean–terrific (assuming the teas are even safe to drink–see below). Just remember: If you go back to your former less-than-stellar eating or exercise habits, or stop drinking the tea, you can gain the weight right back just as quick as you dropped it.
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.
Before a workout, turbocharge the fat-blasting effects by sipping a cup of green tea. In a recent 12-week study, participants who combined a daily habit of 4-5 cups of green tea each day with a 25-minute sweat session lost an average of two more pounds than the non tea-drinking exercisers. Thank the compounds in green tea called catechins, belly-fat crusaders that blast adipose tissue by triggering the release of fat from fat cells (particularly in the belly), and then speeding up the liver’s capacity for turning that fat into energy.
Unless you hit the genetic jackpot, the chances are that your tummy isn’t immune to showing its fat gains. Something interesting is that there are different kinds of belly fat, and they all require different techniques for shedding it. Belly fat isn’t merely an issue of appearance. Sure, it looks and feels nice to have a shredded tummy, but more important are the health implications.
