Tea for Weight Loss / Diet

Tea has been used for weight loss since thousands of years. Some of it’s ingredients make Tea a very strong aid for weight loss and diets. I’m sure most of you have already heard about Oolong or Wu Yi diet tea and wondered, does Tea really work for a diet or weight loss program? Yes it does!!

There are three incredible ingredients in tea that work synergistically to influence the metabolic and nervous systems to help with weight loss and keep it off.

There is hard science behind the tea weight loss connection that explains the synergy of the Tea by it’s powerful ingredients: caffeine, L-theanine, and epigallocatechin-3-gallate (EGCG).

Caffeine is not all bad. It is a natural stimulant that has been shown to boost the process known as thermogenesis, or the generation of heat in the body. This process is at the center of weight loss; it is the way in which fat molecules are „burned”. Thermal energy is divided into calories; the more energy that is expended, the more calories you will burn. Numerous studies have shown that caffeine increases energy expenditure.
A study published in the American Journal of Clinical Nutrition in 1989 concluded that „caffeine at commonly consumed doses can have a significant influence on energy balance and may promote thermogenesis in the treatment of obesity.”

In another study published in the American Journal of Clinical Nutrition, this one is 1999, scientists studying the use of green tea extracts concluded that tea not only promoted thermogenesis, but that unlike caffeine alone, which arouses your nervous system and speeds up your heartbeat, the use of green tea extract was ”not accompanied by an increase in heart rate.” To summarize these two studies, the consumption of tea will increase the burning of calories and promote weight loss without increasing your heart rate.

L-theanine (el-THEE-uh-neen) is a non-protein-based amino acid that constitutes between 1 and 2 percent of the dry weight of tea leaves. Caffeine makes up only about 0.5 percent.
Several minutes after the caffeine has entered your system, the L-theanine is secreted from the small intestine into the blood system and into the brain where it stimulates alpha brain waves, which produce a state of relaxed and effortless alertness, thus canceling out the harmful effects of the caffeine.
Because of L-theanine’s effect on alpha brain waves, it is a natural medicine for the relief of stress, anxiety and tension.

When stress levels decrease, so do levels of cortisol, a hormone that, when stimulated, increases appetite and influences where body fat will be stored (mainly in the abdominal region).

So it seems that L-theanine not only reverses caffeine’s harmful effects but assists to reduce stress, which in turn reduces appetite and the storage of fat in your body.
EGCG is more than a potent antioxidant. It forms a powerful combination with the caffeine and L-theanine and it’s a potent factor in stimulating weight loss. Studies have shown that green tea extracts (containing EGCG) markedly inhibit enzymes in the pancreas that help to digest fat in vitro (in a test tube), which may translate into reduced fat digestion in humans.

So next time your your considering a diet or weight loss porgram, you should definetly look at tea as an easy and efficient way to help you keep those extra pounds off.
