Victoza is a drug designed to control blood sugar levels. It acts similarly to the hormone GLP-1, naturally produced by the pancreas, but in a concentration 8 times greater.
When Victoza enters the bloodstream in addition to controlling blood sugar levels, it promotes satiety within a 24-hour period, causing the individual to have a 40% reduction in the amount of daily calories ingested.
With less desire to eat and with the feeling of satiety promoted by the medicine, caloric intake decreases while the amount of energy spent remains the same, which leads to weight loss without any effort.
