If there is ONE thing you want to know about aging it is this: SUGAR is aging you and here is why: Insulin plays a crucial role in aging and overall health. It regulates blood sugar levels by helping glucose enter cells for energy. However, when the body becomes resistant to insulin, insulin increases in the body and it accelerates aging and increase the risk of age-related diseases. Basically, the more insulin you have floating around the quicker you age.

What is Insulin?

Insulin is a hormone produced by the pancreas that allows cells to absorb glucose from the bloodstream. It helps maintain balanced blood sugar levels and supports metabolism.

Insulin Resistance: A Hidden Driver of Aging

Insulin resistance occurs when cells stop responding efficiently to insulin, leading to higher blood sugar and increased insulin production. Over time, this can cause metabolic dysfunction and contribute to:

• Chronic Inflammation: High insulin levels promote inflammation, a key driver of aging and age-related diseases.

• Oxidative Stress: Excess glucose leads to oxidative damage, harming cells, DNA, and mitochondria.

• Shortened Lifespan: Studies on calorie restriction and longevity show that lower insulin levels are associated with longer lifespans. (NIH Study)

Insulin Resistance & Age-Related Diseases

1. Type 2 Diabetes – Persistent insulin resistance leads to high blood sugar, damaging organs and blood vessels.

2. Heart Disease – Insulin resistance increases blood pressure, cholesterol imbalances, and arterial plaque buildup.

3. Neurodegeneration (Alzheimer’s Disease) – Often called "Type 3 diabetes," Alzheimer’s is linked to insulin resistance in the brain.

4. Obesity & Fat Accumulation – Insulin resistance promotes fat storage, particularly visceral fat, which is highly inflammatory.

How to Improve Insulin Sensitivity & Slow Aging

✔️ Exercise Regularly – Strength training and aerobic exercise improve insulin sensitivity and glucose metabolism.
✔️ Eat a Low-Glycemic Diet – Avoid processed carbs and sugar; opt for fibre-rich, whole foods. ALWAYS add fat and protein to every meal to slow the uptake of sugar from any carbs you ingest 
✔️ Intermittent Fasting – Fasting lowers insulin levels and improves metabolic flexibility.
✔️ Manage Stress – Chronic stress elevates cortisol, which worsens insulin resistance.
✔️ Prioritise Sleep – Poor sleep disrupts glucose metabolism and insulin function.

Conclusion

Maintaining insulin sensitivity and keeping insulin low is key in healthy aging. Elevated insulin levels and resistance contribute to inflammation, metabolic dysfunction, and accelerated aging. By adopting a nutrient dense whole foods diet, regular exercise, and stress management, you can promote longevity and improve overall health.
