Low energy is one of the most common complaints in medicine, coaching, and everyday life, yet it is one of the least precisely understood. People describe it as fatigue, burnout, brain fog, weakness, lack of motivation, or feeling “offline.” Athletes feel it when they cannot train. Patients feel it when they cannot work. High performers feel it when discipline no longer works. The problem is that “low energy” is not a diagnosis. It is a surface description of a system-level failure, and two people can experience nearly identical symptoms while the underlying biology is completely different. Treating them the same way helps one person and harms the other. To understand low energy correctly, you have to stop asking how to boost energy and start asking why energy is being limited in the first place. At the deepest level, there are two dominant failure modes. In one, the body cannot produce enough energy. In the other, the body is deliberately suppressing energy production. The first is mitochondrial damage, a capacity problem. The second is inflammatory inhibition, a regulatory decision. One is a broken engine. The other is a functioning engine with the brakes applied. Subjectively they feel similar. Biologically they are opposites. Everything that follows depends on recognizing which one you are dealing with. A simple model helps. Imagine the body as a car. The mitochondria are the engine. They take fuel and oxygen and convert them into usable energy in the form of ATP. Inflammation acts like the central control computer, deciding how much power the engine is allowed to produce. If the engine is damaged, pressing the accelerator does little. If the computer is limiting output, the engine could perform, but is being intentionally restrained. In both cases the car goes slow. Only one responds to pushing harder. Mitochondria exist inside nearly every cell and are responsible for producing ATP, the molecule that powers muscle contraction, nerve signaling, hormone synthesis, immune regulation, tissue repair, and cognition. Without adequate ATP, nothing in the body functions well. Energy production depends on intact mitochondrial membranes, functioning enzymes, proper redox balance, sufficient oxygen delivery, and a steady supply of micronutrients. When any part of this system is damaged, the maximum amount of energy the body can generate drops. This is not a motivational issue. It is a hard ceiling.

Is here someone who has experience with it? 🙏

Is there any difference between kenetic vs kenetic pro besides the amount of ketones? Are the tastes of the different flavors the same? When I calculate the per mg dose, the regular kenetic comes out to be a lot less expensive even when I use the discounted price that Anthony Castore offers through his buyers club. At higher doses, the Pro is more convenient, but not at a cost perspective.

This Retatrutide carbs vs no-carbs discussion is a perfect example of the kind of work we’ll be doing inside the Cellular Intelligence Circle. I am attaching a video so you guys can get a sense of what to expect. Not hot takes. Not protocols copied from the internet. Not arguing teams or tribes. Instead, I’ll show you how I actually think. How I zoom out, identify what system is really being affected, and trace decisions back to first principles like cellular energetics, redox balance, signaling hierarchy, and context. You’ll see how to move beyond surface-level debates and start asking better questions. The kind of questions that cut through hype, confusion, and false certainty. The goal of the Circle isn’t to tell you what to think. It’s to teach you how to think for yourself. If you’re tired of conflicting advice, overconfident influencers, and protocols that work in theory but fall apart in real humans, this community is built for you. We’ll break down topics like peptides, metabolism, training, recovery, fat loss, and longevity in a way that connects the dots instead of fragmenting them. We kick off in February, and each month will center around a focused agenda designed to build real understanding, not just information overload. Members will get long-form breakdowns, case studies, monthly live Q&A discussions, and practical frameworks they can actually apply. If this video made you stop and rethink the question instead of picking a side, you’re exactly who this was built for. More details coming soon…. The Cellular Intelligence Circle launches February.

With Red light therapy, is it better to utilize in the evening before bed, or upon waking? For more systemic effects, not localized healing.
