For many years, scientists and medical experts have been trying to find the secret to weight loss. Finally, groundbreaking research has found the answer. The secret to losing weight fast and keeping it off, as well as to improving one’s health is reduced eating frequency. Losing weight fast is as simple as eating only one meal a day, and not consuming any snacks at all. The beauty of the One Meal a Day Diet (OMAD Diet) is that you can eat anything you want and as much as you want in one meal until you feel satisfied. You don't even need to exercise much. However, if you want to lose weight as fast as possible you can follow some diet recommendations and an effective exercise plan. The majority of people today eat three meals plus a few snacks every day. The frequency of eating due to snacking has increased over the past 30 years in the U.S. As snack foods have become more readily available and as snacking frequency has increased throughout the years, so have the rates of obesity. Scientific research has found that increased weight gain is largely a result not of the amount of calories consumed per meal, but rather of eating more frequently per day and irregular eating patterns which leads to a disrupted circadian rhythm. All overweight and obese people have a disrupted circadian rhythm which leads to weight gain and a multitude of health problems such as diabetes and heart disease. The weight and health of the body depend largely on how well the circadian clock is working. No matter what diets or exercises you try, if you don’t reset and correct a disrupted circadian rhythm by resetting methods such as eating one meal a day, you will not lose weight permanently. Researchers have discovered that those with a disrupted circadian rhythm were unable to lose weight and keep it off no matter how hard they tried. We need to follow the healthy eating habits of our ancestors, the hunter-gatherers rather than engaging in the bad habit of eating constantly throughout the day. For our ancestors, it was feast or famine. Humans have evolved to endure long periods of time without food and typically ate a big meal only once a day or less. Most cultures around the world today that are thin and healthy only eat one, two, or a maximum of three times per day and do not snack at all between meals except for children and those with extremely fast metabolisms. The skinny French and Chinese cultures do not snack at all or do so very rarely. People in wealthy, developed countries such as America have access to food whenever they want. This has led people to become “grazers” and to eat whenever they feel like it. Eating frequently and snacking has become an addiction for many, with people always wanting something in their mouth. In recent years, some nutritional and weight loss experts have recommended grazing or having five or six “mini meals,” making people believe that this is a healthy eating habit. However, there are no studies to support this way of eating, and there is plenty of scientific evidence against it. The OMAD Diet is extremely successful in helping all to lose weight fast, and keep it off permanently because it addresses the root cause of weight gain—chronodisruption—as well as several other hidden factors.
