Reduce blood sugar in just 15 mins: Not medicines, CMC Vellore-trained doctor shares one basic habit that works better than fancy fixes

As diabetes continues to affect millions of people, experts are increasingly urging individuals to focus on simple, consistent habits that can make a meaningful difference. While many patients look for supplements, specialised diets or new medications to control their blood sugar, doctors say one of the strongest tools is something most people can do anywhere. A recent example shared by senior diabetologist Dr Brijmohan Arora highlights how quickly the body can respond to basic movement, reinforcing the growing evidence that walking remains one of the most effective ways to support metabolic health.

In an Instagram post, Dr Arora, who studied at CMC Vellore and specialises in managing diabetes, blood pressure, cholesterol, fatty liver and obesity, shared an update from his Continuous Glucose Monitor (CGM) showing his glucose level dropping from around 107 mg/dL to 96 mg/dL within 15 minutes. He pointed out that he did not take any supplement or follow a strict diet during this time — the only change was a simple walk during a routine market visit.

He explained that CGM devices allow people to observe how their body reacts moment-by-moment. As he noted, once walking begins, the muscles act like “glucose sinks,” pulling sugar out of the bloodstream and helping bring levels down naturally. According to him, this immediate impact is why walking remains a powerful tool for people dealing with diabetes, prediabetes and insulin resistance.

Walking as a powerful metabolic habit

Dr Arora stressed that walking is affordable, safe and accessible, making it a reliable everyday strategy for people who struggle with rising HbA1c levels or consistently high CGM readings. He added that increased belly fat or worsening blood sugar trends are strong reasons to start walking regularly, even if the steps are small. His message focuses on consistency rather than intensity, emphasising that small daily actions can trigger important metabolic improvements.

Research shows faster walking cuts diabetes risk

Evidence also supports the role of walking in preventing diabetes. Harvard Health highlighted a study published in the British Journal of Sports Medicine in November 2023, which pooled data from over 508,000 adults across ten studies conducted over two decades. The findings showed that faster walking speeds were linked with progressively lower diabetes risk.

The analysis reported that brisk walking between 2 mph and 3 mph corresponded to a 15% reduction in risk, while walking 3 mph to 4 mph brought a 24% reduction. People who walked faster than 4 mph experienced a 39% lower risk. While the study was observational and cannot confirm a direct cause-and-effect relationship, Harvard Health explained that brisk walking is already known to support blood sugar control, weight management and cardiovascular health.
