Energy metabolism is how the body converts food into ATP, the fuel that powers every cell. Calories alone don’t determine health—fuel type does. Glucose requires insulin and has limited storage, while nutritional fats produce ketones that enter cells easily, generate more stable energy, and place less stress on metabolism. Ketogenic metabolism supports mitochondrial efficiency, lower insulin demand, reduced inflammation, and long-term metabolic resilience.

Muscles power every movement, from walking to your heart beating. Like cats stretch instinctively, we should too—especially with age. Starting in your 30s, muscle loss accelerates unless you act. Daily stretching, strength training, and a protein-rich diet—especially complete proteins and key nutrients like vitamin D and magnesium—help preserve strength, mobility, and independence for life.
