The GOLO diet is a short-term weight-loss plan based on eating nutritious whole foods. The diet emphasizes whole foods over processed foods, encourages healthy fats, minimizes added sugars, and all of the meals are portion-controlled. The diet is based on getting your insulin under control, rather than reducing caloric intake or cutting out entire food groups, as the key to a properly functioning metabolism. The company behind the GOLO diet believes that many struggle to lose weight and keep it off due to their hormones, particularly insulin, which plays a key role in metabolic function. The diet is calorie-restricted, which is likely why some people lose weight on it. The diet requires that you significantly reduce your caloric intake, and the money you spend is for the Release supplement, which is a blend of plant extracts and minerals that is supposed to help regulate insulin and glucose levels. The diet is designed to keep your blood sugar steady and stave off hunger. Although the diet emphasizes healthy foods, it is a short-term weight-loss plan, and it is unclear whether it is safe or effective for long-term weight loss.
