Nutrition Reviews Time-restricted feeding and risk of metabolic disease: a review of human and animal studies [moderate evidence]. The British Journal of Nutrition Effect of Ramadan fasting on some indices of insulin resistance and components of the metabolic syndrome in healthy male adults [weak evidence].
These concerns are based on clinical experience and extrapolation from scientific studies; there are very few studies directly addressing the effect of fasting on eating disorders.
However, it was a short study and did not focus primarily on people with a history of anorexia or bulimia.

Further, some studies have shown an increase in LDL particle size with intermittent fasting. Larger LDL particles are thought to be less atherogenic than small, dense LDL particles. The adjusted RMR did not decrease by a statistically significant amount in the ADF group, while it did in the daily caloric restriction group.
However, the difference in RMR decrease between the ADF and daily caloric restriction groups did not reach statistical significance. This is based on the clinical experience of low-carb practitioners and was unanimously agreed upon by our low-carb expert panel. You can learn more about our panel here [weak evidence].

Not only can they make it easier for you to stick to your fast, but they will also encourage natural fat loss and boost your metabolism. Intermittent fasting programs, such as the OMAD diet, help regulate blood sugar levels, reduce the risk of developing cardiovascular disease and diabetes, and prevent hunger pangs.
Whenever we eat, our blood sugar levels naturally rise as our bodies digest the glucose in our food. The hormone insulin, produced by the pancreas, aids in regulating these levels by stimulating glucose storage in cells.
In short—by eating just one meal per day on the OMAD diet, you can reduce the number of sugar spikes your body experiences throughout the day.
This lower frequency and intensity of insulin spikes can assist in managing your average sugar levels and trigger the burning of glucose and fat for energy, reducing the need for insulin.
Following this diet can help stabilize your blood sugar levels , which can positively impact your overall health. Fasting has been linked to reduced inflammation in the body. Chronic inflammation can lead to various health issues and increase the risk of heart disease, type 2 diabetes, and certain types of cancer.
The OMAD diet can help the body promote the production of anti-inflammatory signaling molecules and reduce the production of pro-inflammatory signaling molecules, helping you reduce inflammation in both its acute and chronic variants. Reduced inflammation can, in turn, help ease the symptoms of autoimmune disorders , reduce the risk of certain diseases , and improve your energy and mood.
Fasting regularly can help you improve insulin resistance , which can prevent the development of cardiovascular diseases. This is because insulin regulates blood sugar levels, which can reduce the risk of weight gain and diabetes, both factors for heart disease.
The regulation of these two kinds of lipids can reduce the risk of cardiovascular disease s like stroke, heart failure, or coronary artery disease. People commonly start intermittent fasting to lose weight , reduce body mass index numbers, and effectively burn fat. By eating only one meal per day, you enforce a calorie restriction on yourself, resulting in a calorie deficit necessary for weight loss.
Moreover, once you have gone through at least 12 hours without eating, your body will reach the state of ketosis, boosting your weight loss process even further.
It is also believed that fasting for brief periods can enhance metabolic health , aiding in weight reduction even after fasting. A strict OMAD diet, like many other weight loss approaches, has certain downsides.
Many of its adverse effects will disappear as your body adjusts, but you should be aware of them before making any lifestyle changes. While this approach may result in weight loss for some people, it can also increase the danger of malnutrition or a lack of critical nutrients required for optimum health.
When you just eat one meal per day, it becomes harder for your body to get all the critical nutrients it needs, such as vitamins, minerals, fiber, and other important components of a balanced diet.
Malnutrition can trigger symptoms like:. Undernutrition can also lead to the development of chronic diseases when it becomes a permanent issue. If you feel any of the symptoms mentioned above, either during your fast or a few days later, consider getting a check-up to ensure you stay adequately nourished.
The OMAD diet is a highly restrictive eating pattern involving consuming only one meal every 23 hours, which can trigger intense hunger and binge eating episodes. This can be harmful to your health, since ingesting an inadequate amount of food during the eating window can result in extreme hunger and even lead to binge eating.
Sufferers of compulsive eating tend to overeat large amounts of food quickly, often choosing high-calorie snacks and meals with bad fats and added sugars.
These kinds of foods, when consumed abruptly and in large quantities, can cause weight gain and various symptoms such as headaches and digestive issues. In fact, having an empty stomach during this diet can raise ghrelin levels the hunger hormone , further fueling appetite and potentially leading to binge eating.
If you decide to try the OMAD approach, plan your meals ahead and get rid of any foods that could keep you from sticking to your plans. Eating disorders are significant mental health conditions with long-term and sometimes fatal implications. Restrictive diets like the OMAD diet can intensify disordered eating patterns and contribute to an unhealthy fixation with food and weight.
