Green tea has become very popular due to the essential health benefits it brings. It has a very long history in being used by Asians as traditional medicine for many years. In addition to adding to one’s vitality, in recent years scientific research has also shown that green tea can help with weight loss.

The green tea diet is different from all other tea diets because its liquid is extracted by steaming the leaves of the Camellia sinensis plant as opposed to full oxidation. As a result, the green tea diet preserves a lot more antioxidants for the body to use. The fact that green tea is a natural ingredient makes it a healthy drink which anyone can drink with no long term harmful side effects, unlike other drugs for weight loss.

What are the key health benefits of green tea diet?

The green tea can diet can help fight the signs of aging since it contains big amounts vitamins C and E which are antioxidants. This marvelous drink is an outstanding source of polycatechin polyphenols, antioxidants that can fight free radicals that damage cells. Heart attacks, cancer and diabetes are some of the diseases that can be caused by damaged cell membranes. Due to green tea diet’s polycatechin polyphenols, a person has a better chance of evading ailments and keeping himself healthy for a much longer period of time. One can get better vitality by simply drinking green tea diet.

There are currently ongoing studies on another antioxidant which is available in green tea diet which can potentially cure cancer. Epigallocatechin gallate or EGCG found in green tea diet has been discovered to destroy cancer cells while keeping surrounding healthy cells unharmed. By simply drinking green tea diet, one can also reduce the risk of cancer.

Some studies in recent years have also shown that drinking green tea can help lose some weight. It has been noted by a study published in the American Journal of Clinical Nutrition that with the consumption of green tea diet, the body’s total 24-hour energy expenditure is boosted by up to 4%. Green tea diet helps increase the body’s metabolic rates. With its thermogenic properties, it is only natural that green tea diet can also promote faster metabolism of fats and sugars. With the green tea diet, one can therefore lose weight without doing a workout at the gym.

Green tea can also help your body fight any infections. Some recent studies have shown that drinking tea increases the immunity system, thus strengthening the body’s ability to fight diseases.

In recent years, the green tea diet has also been proved to lower blood pressure and also help asthma sufferers. Green tea contains theophylline which can help muscles surrounding bronchial tubes to relax, thus helping asthma sufferers to breathe easier.

With all these benefits of green tea diet, why should you pass up on boosting your body’s vitality and lose weight at the same time?

Are there any downside effects to green tea diet? Even though green tea diet has a reputation for boosting health, scientific evidence of its health benefits are rather mixed.

In an article published in the Archives of Internal Medicine, American researchers collaborated with their Chinese counterparts to discuss the positive effects of green tea diet on cholesterol levels. Using a sample of 240 men and women (average age 55) who possess moderate to high LDL cholesterol levels, the researchers instructed them to retain their usual low-fat diet, green tea diet intake, and activity levels. After three months, those who consumed green tea diet extract with their regular meals lost more than 15% of their total LDL cholesterol levels. This finding therefore further supported the benefits of green tea.

Based on recent studies and experience, the general consensus is that green tea offers several health benefits and also help with losing weight.

Dieting generally involves eating well and exercising. Green tea diet, like all other diets, needs a lot of effort and commitment for those who try it. This diet requires both discipline and dedication for it to make any significant impact on your weight loss goals. With the green tea diet, you lose weight and also keep your body healthy.

"We looked at macadamia nuts because they are not currently included in the health claim for tree nuts, while other tree nuts are currently recommended as part of a heart healthy diet," says Dr. Amy E. Griel, a recent Penn State Ph.D. recipient in nutrition and now senior nutrition scientist at The Hershey Company. "Macadamia nuts have higher levels of monosaturated fats, like those found in olive oil compared with other tree nuts".

Along with Brazil nuts and cashews, macadamia nuts are not included in the U.S. Food and Drug Administration's list of nuts with qualified health claims because the cut-off point is 4 grams of saturated fat per 50 grams of nuts. Macadamia nuts have 6 grams of saturated fat per 50 grams, cashew nuts have 4.6 grams and Brazil nuts have 7.6 grams of saturated fat per 50 grams of nuts.

"Epidemiological studies showed that people who are frequent nut consumers have decreased risk of heart disease," says Penny Kris-Etherton, co-author and distinguished professor of nutritional sciences.

The researchers used a controlled feeding study to compare a heart-healthy diet with 1.5 ounces a small handful of macadamia nuts to a standard American diet. The participants had slightly elevated cholesterol levels, normal blood pressure and were not taking lipid-lowering drugs. Researchers randomly assigned participants to either the macadamia nut diet or the standard American diet and provided all meals for the participants for five weeks. The participants then switched diets and continued eating only food provided by the researchers for another five weeks.

The Healthy Heart diet with macadamia nuts did reduce total cholesterol, low-density lipoprotein cholesterol and triglyceride levels compared with the standard American diet. The researchers reported in the current issue of the Journal of Nutrition, that the macadamia nuts reduced total cholesterol by 9.4 percent and low-density lipoprotein by 8.9 percent.

Individual calorie levels were used for each participant so that they did not gain or lose weight during the study. Both diets were matched for total fat, containing 33 percent calories from total fat. The Heart Healthy diet with macadamia nuts had 7 percent saturated fat, 18 percent monosaturated fat and 5 percent polyunsaturated fat. The standard American diet had 13 percent saturated fat, 11 percent monosaturated fat and 5 percent saturated fat.

"We found that the reduction in LDL or bad cholesterol we observed was greater than would be predicted by just the healthy fats in the nuts alone," says Griel. "This indicates that there is something else in the nuts that helps lower cholesterol".

The macadamia nut diet included macadamia nuts as a snack, mixed into meals, as a salad topping and in cookies and muffins. The total fat was the same in both diets. Macadamia nuts were substituted for other sources of fat and protein in the diet. Switching skim milk for 2 percent milk and adding some macadamia nuts kept fat levels even.

"I think the bottom line is that Macadamia nuts probably should be included in the list of nuts to have a qualified health claim," says Kris-Etherton.

Your friend can eat whatever she wants and still fit into her prom dress, but you gain five pounds if you just look at that chocolate cake. Before you sign up for Weight Watchers and that gym membership, though, you may want to look at some recent research from Tel Aviv University and save yourself a few hundred dollars.

A womans waistline may have less to do with rigorous exercise and abstaining from sweets than it does with the genes of her parents, as per a new study by Prof. Gregory Livshits from the Sackler Faculty of Medicine at Tel Aviv University and his colleagues from Kings College in London. Dr. Livshits and colleagues have found a scientific link between the lean body mass of a woman and her genes. Theyve determined that thinness like your smile or the color of your eyes is an inheritable trait.

Bad News First, Then the Good
Prof. Livshits, whose findings were reported in the Journal of Clinical Endocrinology and Metabolism (2007), says, The bad news is that a number of of our physical features, including our weight, are dependent on our genes. The good news is that women still have an opportunity to go against their genetic constitution and do something about it.

Until now, researchers were not sure to what extent environmental influences and genetics played a role in a womans body size. When controlling for the variance of age, the differences in womens body sizes can be predicted in the genes more than 50 percent of the time, the scientists found.

Prof. Livshits conducted his study on more than 3,000 middle-aged women in the United Kingdom who belonged to either an identical or fraternal twin pair. He measured their total lean mass, one of the three major components of body weight, and compared it to markers in their genes.


A Slim Chance?
Additional collaborative research between the two teams, which builds on the past study, is would be reported in the next few months. It may help pave the way for a skinny gene test, which one day may help women trying to lose weight understand what kind of battle they can expect.

Those without the lean genes, however, will always find it harder to stay slim, predicts Prof. Livshits. But before your diet falls by the wayside, consider Prof. Livshits contention that genetics can be overcome.


Curb Your Enthusiasm
Its important to not have high expectations, he warns. Women need to know that what they can do about their body weight particularly when they age is relatively little, and they will do it only with much difficulty.

Very few studies to date have been able to associate a bodys lean mass with genetics. The topic is a specialty at the Tel Aviv University lab, one of the top labs in the world to study the genetics of aging of body composition. This area includes the study of bone, fat and lean mass as it develops in a person over time.

Research on body composition components their growth, degradation and genes is part of Prof. Livshits ongoing work on aging and health. Issues such as weight gain are complex, he says, particularly when age is factored in.

So dont get too jealous of your friends dress size. It may be mostly out of your hands and in your DNA.
