The Benefits of Intermittent Fasting for Weight Loss in Type 2 Diabetes
Introduction
Losing weight is an important aspect of managing type 2 diabetes. It has been found to lower blood sugar levels and reduce the need for some diabetes medications. New research has shown that intermittent fasting can be an effective way for individuals with type 2 diabetes to cut calories and shed extra pounds.
Understanding Intermittent Fasting
Intermittent fasting refers to a dietary approach that limits eating to a specific time window each day. In a recent study presented at the annual conference of the American Society of Nutrition, patients with type 2 diabetes were assigned to either an intermittent fasting group or a calorie restriction group. The participants in the intermittent fasting group could only eat between noon and 8 p.m. each day, while those in the calorie restriction group were asked to cut their calories by 25%. A control group continued eating as normal.
This study included 57 overweight and obese people with type 2 diabetes who were randomly assigned to each of these groups. After 6 months, it was found that the intermittent fasting group had lost about 4.3% of their body weight, equivalent to approximately 10 pounds for a person weighing 230 pounds. The calorie restriction group, on the other hand, lost about 2.5% of their body weight.
Comparing Intermittent Fasting and Calorie Restriction
Statistical analysis did not show a significant difference in weight loss between the two groups. This means that one method of dieting is not necessarily better than the other. According to William Yancy, MD, an internist and weight management specialist, intermittent fasting should be seen as an alternative approach to calorie restriction, not a superior one.
One possible reason for the small percentage difference in weight loss could be the difficulty in following calorie restriction diets. Many individuals with type 2 diabetes have already been advised to count calories, and tracking their eating habits consistently can be a challenge. In the study, there were weeks when participants did not track their eating as required, and they had to be encouraged to start tracking again.
Sticking to the diet seemed to be more of a problem for the calorie restriction group. Approximately one-third of them did not stay within 200 calories of their goal. In contrast, the intermittent fasting group reported adhering to the diet for 6 out of the 7 days of the week. This meant that the fasting group cut about 100 calories more per day than the calorie restriction group, which was reflected in their weight loss.
Effect on Blood Sugar Levels
The study also measured the impact of both intermittent fasting and calorie restriction on A1c levels, which is a measure of a person’s average blood sugar level over time. It was found that both groups experienced a drop of about 1% in their A1c levels. This indicates that both methods can effectively help manage blood sugar levels in individuals with type 2 diabetes.
Considerations for Individuals with Type 2 Diabetes
Up to 90% of people with type 2 diabetes are overweight or obese, highlighting the importance of weight loss in their care. Even a 5% reduction in body weight can lead to improvements in blood sugar control. In some cases, type 2 diabetes remission can occur with a 10% loss in body weight. However, the effectiveness of these approaches may vary depending on factors such as an individual’s metabolic situation, duration of diabetes, and other factors.
When considering intermittent fasting, it is crucial to take into account a person’s eating habits and whether their meals typically fall outside the time-restricted window. Skipping breakfast or eating little after 8 p.m. may not have a significant impact on weight loss. Additionally, individuals taking certain medications, such as short-acting insulin or sulfonylureas, should be cautious about fasting as it can be dangerous for them.
Conclusion
The findings of this study indicate that intermittent fasting is a viable option for individuals with type 2 diabetes who are looking to lose weight. It provides an alternative approach to conventional calorie restriction diets. If traditional methods of calorie counting have not worked or individuals feel burnt out, intermittent fasting can be a valuable strategy to try. However, it is essential to consult with a healthcare professional before starting any new diet or fasting regimen, especially for individuals with diabetes.
Summary:
Losing weight is crucial for managing type 2 diabetes, and new research suggests that intermittent fasting can be an effective way to cut calories and shed pounds. In a study involving overweight and obese individuals with type 2 diabetes, those in the intermittent fasting group lost about 4.3% of their body weight after 6 months, while those in the calorie restriction group lost about 2.5%. Both approaches showed a similar drop in A1c levels, indicating blood sugar control. However, it is important to note that the difference in weight loss between the two groups was not statistically significant, suggesting that intermittent fasting is an alternative approach rather than a superior one. Compliance with calorie restriction diets can be challenging, making intermittent fasting a more feasible option for some individuals. Prioritizing weight loss is crucial for managing type 2 diabetes, and even a small reduction in body weight can have significant health benefits. However, the effectiveness of weight loss methods may vary depending on individual factors such as metabolic situation, duration of diabetes, and medication use. It is important to consult with a healthcare professional before embarking on any new diet or fasting regimen, especially for individuals with diabetes.

July 25, 2023 – Losing weight is an important part of type 2 diabetes care – it could help lower blood sugar and reduce the need for some diabetes drugs. To shed the extra pounds, new research shared on Monday shows that intermittent fasting is an effective way to cut calories for people with type 2 diabetes.
Intermittent fasting refers to eating only within a limited time window. In this study, featured at the annual conference of the American Society of Nutrition, patients assigned to that group could only eat between noon and 8 p.m. each day – a practice also called time-restricted eating – with a 1-hour grace period. The people in the calorie restriction group were asked to cut their calories by 25%, and a control group continued eating as normal.
In total, the results included 57 overweight and obese people with type 2 diabetes who were randomly assigned to each of these groups.
After 6 months, those in the intermittent fasting group lost about 4.3% of their body weight – equal to about 10 pounds of weight loss for a person weighing 230 pounds – and people in the calorie restriction group lost about 2.5% of their body weight.
Statistical analysis showed no significant difference between the two groups for weight loss, meaning one method of dieting isn’t necessarily better than the other.
“Let’s not think of this as an approach that’s better than calorie restriction,” said William Yancy, MD, an internist and weight management specialist at Duke Lifestyle and Weight Management Center in Durham, NC. “It’s an alternative approach to calorie restriction.”
The reason for the small percentage difference could be because calorie restriction diets tend to be harder to follow, and people have probably tried to cut calories before, according to study author Vasiliki Pavlou, a registered dietitian nutritionist in the Chicago area.
“People that have type 2 diabetes, they’ve already been to the doctor, they’ve already been told to count calories,” said Pavlou, a doctoral student at the University of Illinois Chicago. There were many weeks, she said, when people in the study did not track their eating as required, and “we’d have to encourage them to start tracking again.”
Sticking to the diet seemed to be more of a problem for the calorie restriction group – about a third didn’t stay within 200 calories of the goal, according to Pavlou. The intermittent fasting group reported that they stuck to the diet 6 out of the 7 days of the week.
That meant the fasting group cut about 100 calories more per day than the calorie restriction group, which was reflected in their weight loss, Pavlou said.
A1c levels – the measure of a person’s average blood sugar level over time – dropped by about 1% in both the intermittent fasting and calorie restriction groups.
Up to 90% of people with type 2 diabetes are overweight or obese, and losing weight is an important part of care. Studies have shown that even a 5% reduction in body weight can reduce blood sugar, and type 2 diabetes remission can occur after a 10% loss in body weight – but it depends on the person.
“It depends on the individual, their metabolic situation, how long they’ve had diabetes, what kind of approach they’re following, maybe what medicines they’re taking,” Yancy said. “There’s a lot of different factors involved in remission.”
Intermittent fasting could work well for the right person – but it depends on a person’s eating habits and whether their meals usually fall outside the time-restricted window, or it could depend on how well a person follows rules, according to Yancy.
“Some people might not eat much after 8 o’clock, and some people might skip breakfast,” he said. “And if that’s the case, then it’s not going to make a big impact on their weight, probably.”
The people in the study generally had advanced type 2 diabetes and were taking a mix of medications, so the results might not apply to people with a more recent type 2 diabetes diagnosis.
Considering the effect of the diet on medications is also important. Not eating can be dangerous for patients taking short-acting insulin or sulfonylureas, Yancy said.
These findings show intermittent fasting is another option for patients with type 2 diabetes who are trying to lose weight. “If you’ve tried calorie counting, that’s not working for you or if you’re kind of burnt out, this is something else that you could try,” he said.
