A few years ago I gave a talk to a small group about metabolic health. The premise was simple: most of us have lost touch with the signals our bodies are constantly sending. We override hunger with schedules, override fatigue with caffeine, and override discomfort with distraction. And we wonder why things start breaking down.

As a biochemical engineer, I spent years studying biological systems professionally, at Nutrartis, working on cardiovascular health products. But it took a surprisingly long time before I turned that same analytical lens on my own body with any real honesty.

The metabolic pendulum

Here's something that I find most people don't fully appreciate: your body runs on two primary fuel sources, glucose and ketones. The relationship between them is not a choice you make once (like picking a diet) but a dynamic cycle your body navigates every day, every meal, every hour of sleep.

When you eat carbohydrates, blood sugar rises and insulin follows. The body stores energy, runs on glucose. When you fast or eat mostly fats, insulin drops, the body shifts to burning stored fat and producing ketones. Both states are natural, both are necessary. The problem isn't either fuel source; it's getting stuck at one extreme.

Constant snacking, high-carb meals throughout the day, keeps insulin elevated, keeps the body locked in glucose mode. Over time, this can lead to insulin resistance, metabolic syndrome, and a cascade of downstream effects that are well-documented in the literature. On the other extreme, never eating carbs at all has its own set of concerns.

The body seems to function well when it can move between these states fluidly, the way it would naturally if we ate in rhythm with our activity and circadian cycles. The natural metabolic cycle isn't a fixed position; it's a wave.

What struck me about this

When I started studying this in detail, what struck me wasn't the biochemistry itself, which is fairly well-established. It was how precisely it parallels what I was learning in other domains.

The body, like any complex system, has its own intelligence. It self-regulates, adapts, compensates. But it can only do this when conditions allow, when the inputs are varied enough and spaced appropriately for the feedback loops to operate.

When we override those loops through constant feeding, chronic stress, disrupted sleep, sedentary living, we're essentially jamming the signal. The body keeps trying to communicate, but we've made ourselves unable to hear it.

The goal isn't a perfect diet. It's metabolic health, where weight loss, if it happens, is a consequence, not the objective. Feel better, look better, while enjoying the process.

A few principles that have worked for me

I want to be careful here. I'm not a nutritionist, and individual variation is real. What follows is what I've found useful based on the research I've studied and my own experiments. Your mileage will vary.

The deeper parallel

What I keep returning to is how similar this is to inner work more broadly. In both cases, the fundamental challenge is the same: learning to listen to a system that's already communicating, but whose signals we've been overriding for so long that we've forgotten how to hear them.

Your body knows when it's hungry and when it's full. It knows when it needs rest. It knows when it's inflamed. But these signals compete with habits, cravings, social conventions, and the constant noise of modern life.

The parallels with emotional life are striking. We override our emotional signals too, suppressing discomfort, performing fine-ness, staying busy to avoid sitting with what's actually there. The result, in both cases, is a system running on overrides instead of intelligence.

The work, in both domains, seems to start in the same place: paying attention. Not adding new inputs, not optimizing aggressively, but first learning to perceive what's already happening. The Happinetics framework begins with exactly this premise, that perception is the foundational function, the body's and the psyche's "sensor," the part that makes contact with reality. Without a clear perception function, we are operating blind, on false or incomplete data.

Whether the domain is metabolic health or emotional well-being, the starting point seems to be the same humble, unglamorous act: feeling what's actually there.
