Metformin Weight Loss?
Metformin for Weight Loss
Metformin is a biguanide medication used to treat type 2 diabetes. It works by lowering blood glucose levels by reducing the amount of glucose released by the liver and increasing the amount of glucose used by the muscles. Metformin is also known to cause weight loss in people with type 2 diabetes, although the exact mechanism of action for this effect is not fully understood.
Clinical Studies on Metformin-induced Weight Loss
Several clinical studies have shown that metformin can cause weight loss in people with type 2 diabetes. For example, a study published in the journal "The Lancet" found that metformin was more effective than placebo in causing weight loss in people with type 2 diabetes. The study participants who took metformin lost an average of 2.5 kilograms more weight than those who took placebo.
Another study published in the journal "Diabetes Care" found that metformin was more effective than placebo in preventing weight gain in people with type 2 diabetes. The study participants who took metformin gained an average of 0.5 kilograms less weight than those who took placebo.
How Metformin Causes Weight Loss
The exact mechanism of action for metformin-induced weight loss is not fully understood, but it is thought to be related to the following:
Reduced blood glucose levels: Metformin lowers blood glucose levels, which can lead to decreased appetite and weight loss.
Increased insulin sensitivity: Metformin increases the sensitivity of cells to insulin, which can lead to improved glucose uptake by the cells and reduced food cravings.
Altered gut microbiota: Metformin has been shown to alter the composition of gut microbiota, which may play a role in weight regulation.
