Every macronutrient has its own pharmacokinetic profile. And when you understand those profiles, you stop guessing and start prescribing—for yourself.

Consider the two most overlooked players in this game.

Protein is the "high-affinity ligand" in the metabolic world. Research consistently shows that protein has the highest thermic effect of food (TEF) of any macronutrient—meaning you burn 20-35% of the calories you consume from protein just through the process of digestion and absorption . A landmark study found that protein treatments resulted in a 13-fold higher thermic effectcompared to carbohydrate, with nearly 25% of the calories from protein being expended over a 3-hour postprandial period . That's not magic. That's metabolic efficiency.

Fibre functions as a time-release capsule. Studies comparing high-fibre and low-fibre meals found that fibre slows digestion, increases fullness, and modulates the thermic response—essentially creating a "slow-release" energy profile that stabilises blood sugar and keeps you fuller for longer . When you eat whole fruit instead of fruit juice, you're swapping a rapid-release bolus for a sustained-release formulation. The sugar is the same. The delivery system is everything.

The bottom line? Not all calories are processed equally. Protein and fibre are the "pharmaceutical-grade" ingredients your metabolism needs to function optimally.

Moving forward through the belts
This newsletter has been running for 26 weeks now and the basics have been covered and we are now going to move forward into refining the kata of our lives rather than just learning new concepts.

We are looking to deepen the mind-body connection and gaining a greater appreciation for our own personal pharmacology.

The ongoing focus will be to now focus on Tsuoy-sa (Diligence) - – the consistent, mindful effort required to move from temporary change to a permanent state of being.

Here's the advanced strategy: re-engineer your plate composition to leverage the thermic effect . At every meal, ensure that:

This isn't calorie counting—this is metabolic design. You're creating the conditions where your body has to work harder to digest what you've eaten. The 30% Rule is your shortcut to leveraging the pharmacokinetics of food, every single time.

Martin had been on a weight loss plateau for six months. He was eating "healthy"—low fat, moderate portions, plenty of salads. But the scale refused to budge. When I asked him to map his typical day, it was a glucose rollercoaster: cereal for breakfast, a sandwich at lunch, pasta at dinner. Carbohydrate. Carbohydrate. Carbohydrate. He was spiking his insulin all day, storing fat, and never giving his body a chance to burn what he had already stored.

We changed the pharmacokinetics. Protein at every meal. Fibre with every carbohydrate. He started breakfast with eggs and spinach instead of cereal. He swapped his sandwich for a protein-packed salad with chickpeas. Dinner became protein-first, with vegetables covering half the plate. Within two weeks, he felt a difference. Within four, the scale started moving again. "I'm eating the same calories," he said, "but I feel like I'm burning more." He was. He was using food as a metabolic tool—not a source of guilt.

"The food you eat can be either the safest and most powerful form of medicine, or the slowest form of poison."

This week's practice is diagnostic. For three days, track every meal and snack. At the bottom of each entry, mark two numbers:

Your goal by the end of the week: protein and fibre at every single eating event. Not perfection—just awareness. The habit begins with noticing.

Stay sharp. Stay consistent. And remember: you are what you absorb, not just what you eat.

Until next time
