What insulin resistance means
Insulin resistance is when your cells stop responding efficiently to insulin, so the pancreas produces more to keep blood sugar normal. Eventually glucose rises — prediabetes, then type 2 diabetes. Central abdominal fat, sedentary lifestyle, poor sleep, and genetics drive resistance in Indian populations.
The encouraging news: insulin sensitivity can improve with weight loss as modest as 5–7% of body weight, combined with movement and better sleep.
Diet priorities for insulin resistance
- Cut sugary drinks, sweets, and refined snacks first
- Replace large white rice meals with millet or smaller rice portions
- Eat protein and vegetables before starch at meals
- Stop eating late at night — aim for 3-hour gap before sleep
- Prioritise 7–8 hours of sleep
- Add daily walking, especially after meals
- Limit alcohol and ultra-processed packaged foods
Foods that support insulin sensitivity
High-fibre dals, legumes, vegetables, whole millets, fatty fish, nuts, and curd are staples worth building meals around. Intermittent fasting approaches help some people but are not suitable for everyone — pregnant women, people on insulin, and those with eating disorders should avoid unsupervised fasting.
Metformin is often prescribed when lifestyle alone is insufficient. It mainly reduces liver glucose output and is first-line in many Indian guidelines.
Measuring progress beyond the scale
Track waist circumference monthly, fasting glucose, and HbA1c every three months. Improved energy, fewer carb cravings, and better post-meal readings are early wins. Insulin resistance also links to PCOS and fatty liver — treating it helps multiple conditions at once.
