Insulin RESISTANCE Is The Reason You're Fat!?

Summary

Dr. Michael Diamonds explains that insulin helps move glucose from the blood into cells. With insulin resistance, cells respond less effectively, so the pancreas may release more insulin while blood sugar remains elevated for longer. He says insulin resistance can make weight loss harder and may progress to prediabetes and type 2 diabetes.

Factors associated with insulin resistance include family history, obesity, inactivity, calorie-dense diets high in sugary foods, nicotine, and poor sleep. Symptoms may not be obvious, though a larger waistline can be a warning sign. He recommends discussing blood glucose, cholesterol, and blood pressure checks with a doctor.

Strategies discussed

• Move more: Gradually build activity through walks, swimming, sports, or gym sessions. Track steps and work toward a personal daily goal; he suggests starting around 8,000 and increasing over time. Add movement by taking the stairs or parking farther away.
• Improve sleep: Aim for about eight hours and keep consistent bed and wake times. Limit late-day caffeine, try relaxation practices such as deep breathing or meditation, and reduce screen use before bed.
  • He shares a “10-3-2-1” routine: no caffeine 10 hours before bed, finish eating 3 hours before, avoid fluids 2 hours before, and avoid screens 1 hour before.
• Adjust eating habits: Increase protein and fiber, reduce junk food and portion sizes, and choose less sugary, more filling foods.
• Work toward fat loss: Create a calorie deficit by eating less, exercising more, or combining both.
• Reduce risk-related habits: He highlights quitting smoking and reducing habits such as smoking and drinking.
• Make changes sustainable: Start with small, manageable habits rather than attempting a drastic diet or lifestyle overhaul all at once.
• Seek medical guidance: If concerned about insulin resistance, consult a healthcare professional about appropriate testing and advice.
