A study compares intermittent fasting and calorie restriction to determine which diet reduces the risk of type 2 diabetes more.

As rates of Type 2 diabetes continue to rise, many people are looking for effective ways to reduce their risk of developing the condition. Two popular approaches are intermittent fasting and calorie restriction, both of which have been shown to have potential benefits for blood sugar control. But which diet is better at reducing the risk of Type 2 diabetes? In this article, we explore the evidence behind both approaches and compare their effectiveness when it comes to diabetes prevention.


Intermittent fasting and calorie restriction are two popular weight loss diets that have gained much attention over the past few years. Both these diets have been shown to have potential health benefits, including reducing the risk of Type 2 diabetes. A recent study published in the Journal of Clinical Investigation has compared the effects of both these diets on diabetes risk and has found that intermittent fasting may be more beneficial in reducing the risk of Type 2 diabetes.

The study involved 46 overweight participants who were randomly assigned to either an intermittent fasting diet or a calorie restriction diet. Those in the intermittent fasting group were allowed to eat only during an 8-hour window each day, while those in the calorie restriction group were instructed to reduce their daily calorie intake by 25%. After 12 weeks, the researchers found that both diets led to weight loss and improvements in insulin sensitivity. However, the intermittent fasting group had greater reductions in fasting insulin levels and insulin resistance, which are important markers for diabetes risk.

These findings are consistent with previous research that has shown the potential benefits of intermittent fasting for improving metabolic health. In addition to reducing diabetes risk, intermittent fasting has also been shown to improve blood pressure, cholesterol levels, and overall cardiovascular health. However, it is important to note that intermittent fasting may not be suitable for everyone and should be approached with caution, especially for individuals with certain medical conditions or who are pregnant or breastfeeding.

Overall, the results of this study suggest that both intermittent fasting and calorie restriction can be effective for weight loss and reducing the risk of Type 2 diabetes. However, intermittent fasting may be more beneficial in improving certain markers of diabetes risk. Regardless of which diet one chooses, it is important to maintain a healthy and balanced diet that includes plenty of fruits, vegetables, and whole grains while limiting processed foods, sugary drinks, and excess saturated and trans fats. Additionally, regular physical activity and stress reduction techniques can further improve metabolic health and reduce the risk of chronic diseases like diabetes.


With an increasing incidence of diabetes across the globe, it is natural for people to explore different diets that can help manage or prevent the condition. This article has highlighted the differences between the popular diets of intermittent fasting and calorie restriction when it comes to reducing the risk of type 2 diabetes. While both diets show some promise in this regard, it is important to understand that there is no one-size-fits-all approach to diabetes prevention or management. It is advisable to consult a healthcare professional before embarking on any diet, especially if you have diabetes or other health conditions. Factors such as individual preferences, lifestyle, and medical history should also be taken into account before choosing a diet for diabetes prevention or management. Ultimately, it is essential to lead a healthy lifestyle that includes regular physical activity and a balanced diet, to reduce the risk of type 2 diabetes and other chronic conditions.
