Short answer: Yes, to a large degree. Meal regularity, carbohydrate quality, adequate protein and fibre, and regular movement improve insulin resistance markedly in most people. Medication decisions rest with your doctor; the nutrition plan is the foundation at every stage.
What is insulin resistance?
Cells respond less to insulin, so the body produces more of it. Signs include sleepiness after meals, sugar cravings, abdominal fat and difficulty losing weight. Diagnosis is by blood tests.
Five changes that work
- Meal regularity: regular main meals instead of long fasts and grazing
- Carbohydrate quality: whole grains, legumes and vegetables instead of white flour and sugar
- Protein at every meal: eggs, yoghurt, legumes, meat, fish
- Fibre: at least 25–30 g a day
- Order: vegetables and protein first, carbohydrates last
Movement
Even a 10–15 minute walk after meals improves the blood-sugar response; strength training 2–3 times a week builds muscle and insulin sensitivity.
