How to reverse pre-diabetes in 21-days: Metabolic doctor shares complete plan

In a 2024 statement, the World Health Organisation (WHO) shared that 'The number of people living with diabetes rose from 200 million in 1990 to 830 million in 2022. (And) Prevalence has been rising more rapidly in low- and middle-income countries than in high-income countries.' This highlights the urgent need to prevent or manage diabetes, which is a fast-growing lifestyle disease. In fact, many people are unaware that they are in the pre-diabetes range, however, if detected early it can be reversed or controlled with the help of proper diet and exercise.

Talking about this, Dr Sudhanshu Rai- Metabolic doctor & Sports Physio- recently shared his eight tips to reverse pre-diabetes naturally in 21-days. "Your body can reverse sugar resistance— one habit at a time. Start the 21-Day Sugar-Control Challenge and feel the difference from Day 3," his post read. Here are his tips:

A 2022 study titled 'Effect of a High Protein Diet at Breakfast on Postprandial Glucose Level at Dinner Time in Healthy Adults' highlights the importance of having a protein-rich breakfast. This is because starting your day with a protein-rich breakfast helps you regulate blood sugar and prevent post-meal glucose spikes. Protein slows down digestion, keeping you fuller for longer and reducing cravings later in the day.
So include protein-rich food items in your breakfast, like eggs, Greek yogurt, cottage cheese, among others.

A short 10-minute walk after every meal can have a huge impact on your blood sugar levels. How? Well, walking burns glucose-- thus walking 10 minutes post-meal can help lower post-meal blood sugar spike. This was also proven in a randomised controlled trial in 2025 titled 'Positive impact of a 10-min walk immediately after glucose intake on postprandial glucose levels'.
However, do remember-- to gain maximum benefits, consistency is the key.

Did you know the sequence in which you eat your food matters the most? So, start your meals with fiber-rich vegetables, followed by protein, and finishing with carbohydrates. This slows sugar absorption and reduces glucose spikes; it also stabilises energy levels and minimises food cravings.
A 2024 study titled 'Food order affects blood glucose and insulin levels in women with gestational diabetes' found that consuming vegetables first, then proteins, and carbohydrates last hugely improved glycemic control and insulin sensitivity, thus reducing after-meal glucose and insulin levels by up to 37%, as compared to the reverse order.
So, begin your meal with salad or sautéed veggies, then move to lentils or chicken, and save rice or chapati for last.

Refined carbohydrates like white rice, white bread, and maida are digested faster and this causes rapid blood glucose spikes. Meanwhile, whole grains like brown rice, quinoa, oats, or millets digest slowly due to the high-fibre content in it. This keeps you satiated for longer and also reduces rapid blood glucose level rise, as per a study in Frontiers.

So, swap white refined carbs for higher-fiber grains to improve your insulin response. However, do note that portion control is important too.Also See: Ice cream for people with diabetes: Know its effects on blood sugar and smart consumption tips​

Eating late in the night, just before going to sleep, gives your body little time to process glucose before sleep. This in turn leads to higher fasting blood sugar. So, instead, aim to finish your dinner at least 3 hours before bed. Following this habit allows insulin levels to stabilise overnight.
A 2021 study on PubMed Central found that people eating dinner early (around 6 PM) had significantly lower blood glucose levels from dinner time through the night and the next morning, compared to those eating late (around 9 PM). The late dinner group showed higher blood glucose fluctuations and overall higher 24-hour glucose levels.
Also, choose a light dinner — like soup, dal, or grilled vegetables — to keep digestion smooth. It will also help you get better quality sleep.

Sleep in one of the most underrated natural medication, it seems. Sleep deprivation is directly linked to insulin resistance and increased hunger hormones. And so, getting 7–8 hours of quality sleep helps your body relax, repair, regulate blood sugar, and manage weight.
A systematic review titled 'Does Insufficient Sleep Increase the Risk of Developing Insulin Resistance' in 2022, showed that sleep loss correlates with insulin resistance, increased inflammatory markers, and impaired glucose tolerance, emphasizing adequate sleep's role in metabolic health.
So, maintain a consistent sleep routine, limit screen time before bed, and create a dark, cool sleeping environment for good quality sleep.

Chronic stress increases cortisol levels, which spike blood sugar and promote fat storage in the body, as per a 2022 study titled 'Stress-Induced Diabetes'.
On the contrary, just five minutes of deep breathing or meditation daily can help reduce stress hormones, lower inflammation, and improve insulin sensitivity.
This small daily practice can help calm your mind, reduce cravings, and help the body heal naturally.

Dr Rai further shared that one should monitor their fasting blood sugar and HbA1c levels to see any progress or change. HbA1c reflects your average glucose levels over 3 months. Tracking these numbers keeps you accountable and helps detect any early warning signs for diabetes.

"By Day 3: Energy feels steady, by Day 7: Cravings ease up," Dr Rai shared. He added, "Run it 6 weeks to reset metabolism and numbers."

Consuming a healthy diet can keep sugar levels in control

Research from the Harvard T.H. Chan School of Public Health revealed that when combined with modest calorie reduction and regular physical activity, the Mediterranean diet can reduce diabetes risk by nearly one-third among people with metabolic risk factors.

To check your blood sugar at home, start by preparing your glucometer, test strips, and lancet device. Wash your hands thoroughly with soap and warm water to remove any residue that could affect the reading. Insert a test strip into the glucometer, then prick the side of your fingertip using the lancet to obtain a small drop of blood. Gently place the blood on the test strip and wait a few seconds for the glucometer to display your reading. Record the results carefully in a logbook or app. For accurate monitoring, test at consistent times, such as fasting, before meals, or after eating and share your readings with your doctor for better diabetes management.
