Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, due to a mean loss of fluid, body fat or adipose tissue and/or lean mass, namely bone mineral deposits, muscle, tendon, and other connective tissue. Weight loss can either occur unintentionally due to malnourishment or an underlying disease or arise from a conscious effort to improve an actual or perceived overweight. Intentional weight loss is the loss of total body mass as a result of efforts to improve fitness and health, or to change appearance through slimming. People are being advised to do all sorts of crazy things, most of which have no evidence behind them. Over the years, however, scientists have found a number of strategies that seem to be effective. Here are weight loss tips that are actually Faster and safety. There are ways to rev up your metabolism so you burn calories and lose weight more quickly.

Drink green tea: When a recent study compared the metabolic effect of green tea with that of a placebo, researchers found that the green-tea drinkers burned about 70 additional calories in a 24-hour period. Green tea contains small amounts of caffeine, but it is also loaded with powerful antioxidants called catechins, which are also believed to work synergistically with the caffeine to enhance fat burning. There are many studies showing that green tea can help you lose weight.

 Avoid calories in a glass:  Scientists now know that the body does not register liquid calories in the same way it does solid calories. Drinking grande caffe mocha, for instance, won’t make you feel satiated the way eating a bowl of pasta will. This means that although the caffe mocha actually has a greater number of calories than the pasta, you’re still more likely to want a second cup from Starbucks than another plate of linguine. So monitor your intake of juice, soda, coffee drinks and wine.

Get some sleep: As funny as it sounds, sleep deprivation may make you fat and not just because you’re susceptible to cases of the late-night munchies .Women who get less than four hours of sleep per night have a slower metabolism than those who snooze for a full eight hours, according to researchers at the University of Chicago.

Go for an evening walk: Exercising at any time is good for you. But evening activity may be particularly beneficial because many people’s metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you’ve stopped moving. What that means for you, those dinner calories have less of a chance to take up permanent residence on your hips.

Eat more protein: Protein is the single most important nutrient when it comes to weight. Eating a high protein diet has been shown to boost metabolism by 80 to 100 calories per day, while helping you feel so satiated that you eat up to 441 fewer calories per day. Simply adding protein to your diet is one of the easiest, most effective and most delicious ways to lose weight.

Add 20 minutes of exercise per day: whether you exercise or not, you can get a leg up on all those other weight-loss wannabes by doing a little something extra each day. Take the stairs instead of the elevator; walk to the bus, train, or all the way to the office; window-shop with your best friend rather than sit over coffee. Taking the dog out, gardening and even housecleaning all increase the number of calories you expend.

Weight loss in individuals who are overweight or obese can reduce health risks, increase fitness, and may delay the onset of diabetesWeight loss occur when the body is expending more energy in work and metabolism than it is absorbing from food or other nutrients. It will then use stored reserves from fat or muscle, gradually leading to weight loss.
