Easy - dont eat until lunchtime, only eat boiled eggs for lunch. Eat a lot of meat and veg for dinner.

You don’t have to starve yourself to achieve it  • Intermittent Fasting and Time-Restricted Eating: Cycling between periods of eating and fasting (such as the 16:8 method or 24-hour fasts) depletes glucose and lowers insulin levels, signaling cells to begin cleanup. • Continuous Calorie Restriction: Consistently reducing daily calorie intake without full starvation forces cells to adapt and repurpose existing cellular components for energy. • Ketogenic Diets: Eating a high-fat, very low-carbohydrate diet shifts the body from burning glucose to producing ketones, mimicking the metabolic state of fasting. • Regular Exercise: Aerobic workouts, high-intensity interval training (HIIT), and resistance training act as acute stressors on muscle and tissue, activating energy-deficit sensors like AMPK that trigger autophagy. • Consuming Specific Polyphenols and Compounds: Certain dietary compounds—such as green tea, coffee, turmeric (curcumin), resveratrol in grapes, and berberine—have been shown in studies to upregulate autophagic pathways. • Optimizing Deep Sleep: The body naturally ramps up cellular repair and waste clearance, particularly in the brain, during deep rest and circadian-aligned sleep cycles. • Managing Chronic Stress: Lowering cortisol and reducing systemic inflammation through mindfulness or gentle movement prevents stress-induced suppression of metabolic balance.

It's this for DT2?
