Having a healthy digestive system is essential for an optimal metabolism. This is because during the digestion process, our body breaks down food into nutrients, absorbs them and uses them to perform different functions, including energy production. Therefore, if the efficiency of our digestive system is reduced, it can lead to slow digestion, limited absorption of nutrients and a slowed metabolism, contributing to weight gain. In addition, an imbalance in the gut microbiota, called dysbiosis, with an excessive proliferation of certain pathogenic bacteria and/or a decrease in good bacteria, can lead to various disorders such as chronic inflammation, insulin resistance and metabolic disturbance, which prevents good weight management.
