Green Tea Shows Body Weight and Fat Benefits

Unwealthy weight is a growing public health concern affecting millions of adults. In the last thirty years, the number of overweight adults has doubled.  OUnhealthy weight is associated with a slew of health concerns. It has impacted the nation as a whole leading to a less productive workforce and skyrocketing healthcare costs. 1-5

With two-thirds (67 percent) of the American population overweight, more and more Americans are earnestly seeking weight loss products resulting in an escalating market for a wide range of weight loss aids.

Be Proactive in Providing Nutritional Solutions

Weight is not just a problem in the United States. According to the World Health Organization, the overweight population across the globe will be more than 1.5 billion by 2015 with related health costs rising beyond $117 billion in the US alone. 6 The weight crisis should prompt supplement companies to play a proactive role in providing a variety of nutritional solutions to help mitigate the problem. Although the weight loss industry is competitive, successfully designed entry-level products hold tremendous potential for growth. The industry is booming, and supplement companies that showcase a well-designed formula that is backed by science have a major advantage.

Green Tea and Healthy Metabolism

Despite green tea being alien to our western culture, it has had phenomenal success as a powerful antioxidant and is a widely sought-after health ingredient in functional foods and beverages. Beyond the benefits of green tea supplements for fat oxidation, it is believed to play an effective role in promoting cardiovascular health, supporting healthy glucose levels already withing the normal range, and supporting oral health. 7 With research supporting its metabolism increasing properties, green tea is now establishing itself as an effective ingredient in the weight loss market. Its appeal lies in its ability to burn calories more quickly, thereby enhancing the weight loss results of any diet regimen.

How Green Tea Promotes Healthy Weight Loss

In contrast to black tea which is crushed and fermented, green tea is steamed or pan-fried and therefore, retains a large percentage of tea polyphenols known as catechins. The four main polyphenols contained in fresh tea leaves are epigallocatechin gallate (EGCG), epigallocatechin, epicatechin gallate, and epicatechin. Of these, the polyphenol that plays the biggest role in promoting weight loss is epigallocatechin gallate (EGCG) found in green tea.

Researchers at Pennsylvania State University studied the gamut of laboratory, epidemiological, and human intervention studies demonstrating the benefits of green tea weight loss and concluded that green tea may have great potential to support weight management. The consumption of 3 to 10 cups of green tea a day was seen to promote weight loss, and help maintain body weight following weight loss. 8

How does green tea work its weight loss magic? After reviewing the extensive research on green tea weight loss, scientists have proposed three mechanisms by which EGCG may support weight loss results. 9

  • EGCG may increase energy metabolism and fat oxidation.
  • EGCG may also inhibit fat cell development, called apidogenesis.
  • EGCG may help the body to excrete fat more efficiently by reducing lipid absorption during digestion.

Green tea contains about half the caffeine content of coffee. Scientists have observed that EGCG needs a stimulated nervous system, which caffeine provides, to produce its fat burning effects. A daily dose of 300 mg of EGCG was seen to increase fat oxidation by 33 percent. However, a combination of 300 mg of EGCG and 200 mg of caffeine increased fat oxidation by almost 50 percent! 10

More Exciting Benefits Associated With Green Tea Supplementation

A separate study, reported in the Nutrition Journal, shows that the benefits of green tea weight loss may include increased post-meal satiety. This study is the first to show that green tea not only promoted increased satiety increased, but subjects in the study reported feelings of fullness and having had enough to consume. 11

Popular Delivery Systems for Green Tea Weight Loss Supplements

Green tea weight loss supplements can be manufactured in several convenient delivery systems such as tea bags, liquid extracts and capsules.

A new delivery system for green tea is the nano-encapsulation of EGCG and its application in a variety of supplement forms. Nano-encapsulation would allow EGCG particles to have good transparency and allow EGCG to be added to all types of liquid supplements, including dairy and sports drinks. Frost & Sullivan report a booming market for green tea extract with a growth of 13 percent over the next 7 years. 12
