Mark Bell's Power Project The Sugar Diet, Immune Cells & Why Diet Isn’t “Static” | Joel Greene
12 snips
Feb 18, 2026 Joel Greene, a nutrition and longevity researcher and coach, breaks down why the sugar diet can work short-term and how glycolysis, gut bacteria, and immune cell metabolism shift over time. He explores insulin complexity, carbohydrate sources, rhythmic pulses versus rigid routines, and practical eating patterns for long-term metabolic resilience.

Episode notes
Body Is A Dynamic Equilibrium
- The body is not a static machine but a dynamic system chasing a shifting equilibrium.
- Repeated dietary inputs produce curves over time, not fixed linear responses.
Glycolysis Explains Sugar Diet's Quick Results
- Sugar drives glycolysis which strongly promotes leanness in the short term.
- But sugar also steers immune cell metabolism and can shift immune populations long-term.
Sugar Source Shapes Gut Taxa
- Different sugar sources feed different gut taxa and shift the microbiome composition.
- Long-term sugar exposure can create overgrowths that produce unwanted outcomes.
