Recent British research has shown that consuming green tea extract greatly increases the burning of fat and it additionally benefits insulin sensitivity in healthy men. In the study the men engaged in half an hour of moderate intensity exercise before and after taking the green tea extract or a placebo. In the case of the men who took the green tea extract their fat oxidation was more than 15% greater compared with the men who took the placebo. For the men who took the green tea extract their fat burning proved to be a larger contributor to their total energy expenditure.
In the second half of the study the researchers measured the subjects’ glucose tolerance before and after they consumed the green tea extract. The researchers found that after consuming the green tea extract the subjects showed improvements in insulin sensitivity. A similar study in Japan reported that adults suffering from visceral-type obesity showed reductions in body fat, blood pressure, and low density lipoprotein (LDL) after consuming a high-catechin green tea extract. The results of these two studies indicate that consuming green tea extract can provide anti-aging effects against both cardiovascular disease and diabetes. This is good news for seniors who are concerned with taking preemptive anti-aging steps to improve their senior health.
