Green Tea Component Does It Promote Energy Expenditure?

Green tea contains a chemical called epigallocatechin gallate (EGCG), which promotes fat loss and protects the cells from free radicals produced naturally during metabolism. A study in the European Journal of Clinical Nutrition, found that caffeine (200mgs per day for 3 days) increased energy expenditure, while EGCG (300 or 600mgs per day for 3 days) had no effect. Several studies found that EGCG and green tea promoted weight loss and reduced the risk of some types of cancer. However, these studies are controversial, and more research is needed before this supplement is recommended for weight loss or cancer prevention.

Leucine Improves Blood Sugar Control

Leucine is a branched-chain amino acid that serves as a building block for new proteins, and is a key signalling chemical for protein synthesis and blood sugar regulation. A study in Nutrition Metabolism, conducted by Columbia University in New York City, found that leucine improved blood sugar control in obese and diabetic mice. The mice were given leucine supplements in their drinking water for 8 months. Leucine stimulates insulin release by the pancreas and promotes the production of the amino acid glutamine, which is important for immune system health. Long-term supplementation of leucine improves the efficiency of insulin metabolism in people with type II diabetes.

Alpha-Lipoic Acid Promotes Caloric Expenditure

Lipoic acid supplements increase the size and number of mitochondria, according to a study from the China Agricultural University in Beijing. The mitochondria are the powerhouses of the cells that provide the body’s energy needs, determine endurance exercise capacity, and greatly influence lifespan. Lipoic acid protects the mitochondria from highly reactive free radicals produced naturally from during metabolism. It also helps to stabilise blood sugar metabolism. Supplementing lipoic acid in aging mice improved energy metabolism and increased cell mitochondria production. It also improved body composition, blood sugar regulation, and increased energy expenditure and fat-free weight (lean mass). Lipoic acid, also known as alpha-lipoic acid, might be an effective anit-aging supplement that promotes metabolic health.
