Does L-Theanine Help With Weight Loss?

Many government websites claim that there is recent research on mice and L-theanine in which they administrate L-theanine in mice; it is proved that L-theanine helps in reducing fat growth in mice. L-theanine activates the browning of subcutaneous white adipose tissue (WAT), which stores the excess energy, and browning of WAT occurs when WAT cells become more like brown adipose tissue, which is responsible for burning calories in the form of heat.

Benefits Of Weight Loss

L-theanine is present in the tea leaves. It has some benefits in boosting metabolism and speeding up weight loss. Many other psychological effects also promote weight loss, such as:

1. Manage Craving

Most of the extra calories you eat are because of carvings and stress eating. Basically when your stomach is full, but your mind signals you to eat something tasty.

It has been shown that l-theanine raises gamma-aminobutyric acid (GABA) levels, a neurotransmitter that suppresses appetite. Additionally, it has been proven that L-theanine raises glutamine levels, an amino acid that has been observed to reduce appetite or cravings.

2. Improving Fat Burning

By activating brown adipose tissue (BAT), L-theanine may boost the body's capacity to burn fat. Compared to white adipose tissue (WAT), the type of fat that is normally stored around the abdomen and thighs, brown adipose tissue (BAT) is more metabolically active and produces heat.

3. Improving Insulin Sensitivity

Many research suggests that L-theanine enhances insulin sensitivity, which may lower blood sugar levels and encourage fat reduction.

A hormone called insulin promotes the body’s use of glucose as energy. Weight gain may result from the body’s reduced ability to utilize glucose when insulin sensitivity is reduced.
