Would you believe that by limiting the number of hours in a day that you eat you could lose weight, slow the aging process, improve insulin sensitivity, and lower your risks for cardiovascular disease, diabetes and cancer?
That’s exactly what modern research is telling us.The journal Cell in an article entitled Promoting Health and Longevity through Diet: From Model Organisms to Humans tells us that limiting daily food intake to a 5 to 7 hr time window while consuming the normal number of calories can improve health when compared with a standard three to five meals per day.
Another journal, Cell Metabolism, presents the article Time-Restricted Feeding Is a Preventative and Therapeutic Intervention against Diverse Nutritional Challenges. It describes experiments done on mice, which are near enough to humans to tell us what will be effective for us.
The experimenters tested various conditions including time restricted feeding (with 8-9 hours food access) seven days a week, and time restricted feeding only five days a week. Time restrictions only 5 days a week is of particular interest because it reflects a more relaxed feeding schedule we normally use on the weekends.
They tested diets that were high in fat, and diets that were high in both fat and fructose. You probably know that fructose is particularly important since it is being added to almost all manufactured and processed foods found in the grocery store. Consuming a high fructose diet can cause glucose intolerance and fatty liver disease.
They found that the benefits of time restricted feeding were proportion to the fasting duration. That is, the longer the mice went each day without food, the more healthy the mice become. So even though they consumed the same number of calories, the duration of the fasting interval were the controlling factor.
For mice on a high fructose diet, they found that when they increased the availability of food from 9, to 12, to 15 hours a day, the percentage of fat mass increased in a linear fashion. The longer the mice had to eat their allotted food, the fatter they became.
The journal Nutrition Reviews presented an article Time-restricted feeding and risk of metabolic disease: a review of human and animal studies. This article indicated that animal studies of time restricted feeding have shown “reductions in body weight, total cholesterol, and concentrations of triglycerides, glucose, insulin, interleukin, and tumor necrosis factor-α as well as with improvements in insulin sensitivity.” They go on to indicate that human studies confirm these results.
Time restricted eating may just be the key you are looking for in your weight loss journey. After all, the longer your body goes without consuming sugars, the longer your body will be forced to burn fat. And, that’s what will provide long lasting health to an overweight generation.
Time-Restricted Eating May Reverse Diabetes & Obesity
Prof. Satchin Panda, Amandine Chaix, and Amir Zarrinpar of the Regulatory Biology Laboratory at the Salk Institute explain their discovery that time-restricted eating shows signs of reversing the effects of obesity and diabetes in mice.
