Improving insulin sensitivity does not necessarily require extreme diets or eliminating entire food groups. Regular physical activity and balanced nutrition can help the body use glucose more effectively and support healthier blood sugar levels.
Insulin is a hormone that helps glucose move from the bloodstream into cells, where it can be used for energy. When the body becomes less responsive to insulin, known as insulin resistance, blood glucose levels may rise. Over time, this can increase the risk of prediabetes and type 2 diabetes.
Fitness coach Aditi Agrawal, who has studied molecular biology and cellular pathways, highlighted the role of skeletal muscles in glucose regulation in an Instagram post. Muscle tissue uses glucose for energy, making movement and exercise important parts of metabolic health.
Here are four lifestyle approaches that may help improve insulin sensitivity.
Strength training: Exercises such as squats, resistance-band workouts and weight training help build and maintain muscle. Active muscle tissue uses glucose, and regular resistance exercise can support better blood sugar regulation.
Movement after meals: A short walk after eating can help working muscles use some of the glucose released into the bloodstream during digestion. Even light movement may be helpful for people who spend long periods sitting.
Include protein in meals: Foods such as eggs, lentils, beans, yoghurt, fish and tofu provide protein that supports muscle maintenance and overall nutrition. Protein is best included as part of a balanced meal rather than treated as a standalone solution for insulin resistance.
Eat more fibre: Vegetables, fruits, whole grains, legumes, nuts and seeds provide dietary fibre. Fibre-rich foods can slow digestion, support fullness and help moderate post-meal blood sugar changes.
These habits can contribute to better metabolic health, but results vary between individuals. People with prediabetes or diabetes should follow personalised medical advice and prescribed treatment rather than relying on lifestyle changes alone.
