CLAIM:
Post-meal walks can significantly lower blood sugar levels and help prevent diabetes. Regularly walking for 10 minutes after meals improves digestion and may stop a person from developing diabetes altogether.
FACT:
Post-meal walks can help lower blood sugar spikes and improve glucose control, with studies showing benefits even from short walks of 10–30 minutes. However, there is no evidence that this habit alone can prevent diabetes, as long-term risk depends on overall lifestyle, diet, and genetic factors.
India is facing a growing diabetes crisis. Nearly 7.7 crore adults in the country are living with type 2 diabetes, while another 2.5 crore are prediabetic—putting them at high risk of developing the condition. What is more concerning is that over 50% of people remain unaware of their diabetic status, increasing the chances of complications such as heart disease, stroke, kidney failure, and vision loss.
In this backdrop, simple lifestyle interventions often gain attention online.
In a viral reel posted by Instagram creator Priyanka Bhatt, a commonly suggested habit for managing blood sugar has been highlighted.
In the reel, Dr Akshat Chadha, a lifestyle consultant, explains that post-meal walks can be beneficial, especially for people with diabetes or prediabetes. He describes it as a simple practice - walking for about 10 minutes after finishing a meal, whether at home or in the office. For those unable to walk, he suggests alternatives like calf raises.
He further explains that he has “seen really good results with post-meal walks,” noting that they help reduce postprandial (post-meal) blood sugar levels. According to him, the practice also aids digestion, adding that “if you digest better, your sugar levels automatically come down and you are not going into diabetes basically.”
The reel has gained 2.98 lakh views, 2,826 likes, and 6,594 shares.
So, should you start walking after meals to keep diabetes away?
Studies suggest that post-meal walking, whether for 10, 15, or 30 minutes, can help reduce blood sugar spikes and improve glucose control. However, it is important to note that while this habit supports diabetes management, it is not a standalone solution to prevent or cure the condition.
A 2015 study involving people with type 2 diabetes examined different walking speeds after meals. Participants performed 30-minute walking sessions one hour after lunch at varying intensities. The findings showed that compared to natural walking, “fast walking markedly improved postprandial glucose excursion in an intensity-dependent manner without any adverse effects.” The study concluded that “fast walking acutely reduced postprandial blood glucose levels,” highlighting its potential role in diabetes management.
Building on this, a 2017 study focusing on individuals with type 1 diabetes explored shorter durations of activity. Participants walked for 15 minutes immediately after consuming a carbohydrate-rich drink. The results showed that post-meal walking significantly reduced blood sugar spikes. As the study notes, “fifteen minutes of postprandial walking can blunt the spike in BG and overall glycemic response to a breakfast beverage in young adults with T1DM and may be an effective and realistic component in the management of T1DM (type 1 diabetes).”
More recent research continues to support these findings. A 2022 study on healthy individuals found that 30 minutes of brisk walking after meals “substantially reduced the glucose peak,” regardless of the type or composition of the meal. The researchers concluded that postprandial walking “improves the glycemic response after meals with different carbohydrate content,” making it a practical tool in daily life.
Interestingly, even shorter durations may be effective. A recent 2025 trial comparing different walking timings found that a “10-min walk immediately after a meal appears to be an effective and feasible approach for the management of hyperglycemia,” with participants showing lower overall blood glucose levels compared to when they remained inactive.
Expert advice
Dr Rajiv Kovil, Head of Diabetology and Weight Loss Expert at Zandra Healthcare, explained that while the idea behind post-meal walking is valid, there is no evidence to suggest it can “prevent diabetes on its own.”
Dr Kovil highlighted that post-meal blood sugar is an important but often overlooked factor. While most people focus on fasting glucose and HbA1c, he noted that “post-meal glucose is independently associated with cardiovascular risk and endothelial dysfunction.”
Explaining the mechanism, he said that after a carbohydrate-rich meal, blood glucose rises and muscles become the primary site for glucose absorption. Light to moderate activity helps improve this process. “If someone does light to moderate physical activity, insulin-dependent and non-insulin-dependent glucose transport increases, and that helps,” he said. He added that “short bouts of activity immediately after a meal help postprandial glucose levels more effectively than longer bouts at other times of the day.”
Based on this, he recommends consistency over intensity. “My advice to most patients is to do a 15–20 minute walk after every meal rather than one long walk,” he said.
He also pointed out that post-meal walks can improve insulin sensitivity, support weight management, and reduce triglyceride spikes that contribute to endothelial dysfunction. Calling it a “very low-cost” intervention, he said it can be easily incorporated into daily routines.
However, he emphasised that diabetes prevention requires a broader lifestyle approach. Referring to long-term research such as the Tübingen Family Study, he said that “all diabetes prevention studies show that it is lifestyle together. Walking alone is not enough.”
He further suggested that timing may play a role, noting that a post-dinner walk could be particularly helpful as nighttime is often “the most vulnerable period for weight gain, high sugar, high triglycerides and high lipids.”
