Metformin primarily works by improving insulin sensitivity. This means your body uses insulin more effectively to transport glucose from your bloodstream into your cells for energy. Reduced blood glucose levels subsequently lower insulin production. This process impacts appetite by influencing hormones like ghrelin, the “hunger hormone”. Metformin can decrease ghrelin levels, leading to a reduction in feelings of hunger.
Metabolic Changes
Beyond appetite regulation, metformin also affects metabolism through several mechanisms. It can slightly increase energy expenditure, meaning you burn more calories at rest. Additionally, it might influence the gut microbiome, potentially altering how your body processes and absorbs nutrients. These combined effects contribute to weight loss in some individuals.
Individual Variability
However, it’s crucial to understand that weight loss with metformin is not guaranteed. Response varies greatly between individuals. Factors such as genetics, diet, exercise levels, and overall health significantly influence the outcome. A balanced diet and regular exercise remain vital components of successful weight management, regardless of medication.
