This is the “adult phase” of metabolism, and it is rock stable from age twenty to sixty.

This apron of fat has a big job to do—it processes energy for your metabolism, regulates your appetite, controls inflammation, and stimulates your health defenses, including regeneration.

Carbohydrates are our primary energy source. In digestion, most carbohydrates are broken down to glucose, which is consumed by all cells to create energy in the form of ATP. Excess glucose, beyond what we need immediately, can be stored in the liver or muscles as glycogen for near-term use or socked away in adipose tissue (or other places) as fat.

After a person has finished digesting the last calorie from a meal, the first source of backup

1. Don’t Mix High Fats & High Carbs — Avoid metabolic traffic jams


2. Treat Fat Like a Supplement — Saturated fats > PUFAs, time fat intake


3. Use the Fat Hierarchy —
   
   
   • S-tier: MCT, stearic acid (tallow, cocoa butter)
   
   
   • A-tier: EPA/DHA, lauric acid (coconut oil)
   
   
   • B-tier: Olive oil, mac nuts (sparingly)
   
   
   • F-tier: Seed oils, trans fats (never)


4. Leverage Starches

What you may not know is that your basal metabolic rate is responsible for so much more than simply how many calories your body burns at rest. It also sets your heart rate, blood pressure, breathing rate, temperature, the speed at which your cells consume oxygen, and more.

Metabolism is the term for the biochemical process of breaking down the molecular bonds in the fats and sugars for the energy needed to assemble the molecule ATP.
