You just ate a full meal. You consumed enough calories. So why are you hungry again 45 minutes later?
Or maybe it's 3 PM—you've eaten plenty, but you're running on fumes, struggling to focus, and craving something sweet or starchy.
Most people blame willpower, blood sugar, or a lack of protein. In Part 2 of Zane Griggs' series on seed oils and mitochondrial health, he explores a different possibility: what if the problem isn't how much energy you're eating, but how efficiently your cells are converting that food into ATP?
In this episode, Zane breaks down the difference between food energy and cellular energy, how your mitochondria convert calories into ATP, and why inefficient energy production may contribute to hunger, cravings, fatigue, brain fog, poor recovery, and stubborn body composition.
He also continues the mitochondrial story from Episode 1, exploring how PUFA-rich mitochondrial membranes may contribute to proton leak and cardiolipin damage, how lipid oxidation products such as 4-HNE and MDA can interact with mitochondrial DNA, and why these processes may become increasingly relevant as we age.
Zane also explains what these issues can look like in everyday life: feeling unsatisfied after meals, afternoon cravings, energy crashes, poor exercise recovery, and body composition that doesn't seem to respond proportionately to your diet and training.
This is Part 2 of the Healthy AF series examining seed oils, mitochondrial function, and metabolic health.
