‘I’ve been doing keto for weeks and I feel worse, not better.’

I hear this all the time. And usually, they were never actually doing keto.

Here’s the thing. Your body prefers glucose. As long as there’s enough sugar around, it’ll burn that first and leave your fat stores untouched.

Your body hates making ketones, so unless you send the message that glucose is unlikely to arrive any time soon, it’ll wait for the next hit rather than fire up the ketone production machinery.

That feeling of being tired, hangry, weak and dizzy?

That’s your body desperately waiting for glucose.

The clarity and steady energy on the other side of that? You don’t get there if you keep reintroducing glucose. You stay in limbo.

So if you eat low-carb all day but top up with something carbohydrate rich at night, you never make the switch to burning fat. You just carry the hunger of a carb-burner without ever getting the steady energy of a fat-burner.

Not enough carbs to feel fuelled. Not low enough to tap into your fat. The worst of both worlds. Tired all day, wired at night, hungry the whole time.

If you’re going to do it, commit properly. The halfway house gives you the downside of both.

Save this for the next time someone tells you keto made them feel worse.

Two things make a diet great. Neither is complicated.

One: eat more micronutrient-dense whole foods. Nuts, seeds, berries, veg, quality meat.

Two: cut back hard on the pro-inflammatory ultra-processed stuff.

Most people who walk into my clinic tired, foggy, flat, dealing with a flaky scalp, only want to do the first one. Add the good stuff, ignore the rest. It feels productive.

Here’s the catch. You can eat all the berries and greens in the world, but if you’re still putting away a tub of ice cream or a stack of pastries every day, the symptoms that brought you in probably aren’t going anywhere.

Not all tiredness is the same.

Both kinds of tiredness involve a buildup of adenosine throughout the day, but the kind of tiredness resulting from poor sleep also brings with it a dysregulation of several hormones and neurotransmitters, and it’s this dysregulation that leads to the ‘hungry ghost’ feeling, that predisposes you to the kind of impulsivity that leads to another poor sleep.

All hail ODOUROUS FLATUS.

If your farts are abundant and smell like rotten eggs, it’s often the result of excess protein making its way to parts of the digestive tract that it normally wouldn’t. Once it’s there, it gets putrefied by the microbes that live there. Unless you provide their preferred substrate- fermentable fibre.

Two fixes- best deployed concurrently. Reduce protein intake to a sensible volume, and increase fibre intake (gradually).

Fermentation of fibres like resistant starch still produce gas, particularly if you introduce too much too fast. But it is far less ODOUROUS 🏛️

**Firstly, if you’re on a prescribed SSRI, do not cease taking it. SSRIs do help some people, but not simply by ‘elevating’ serotonin. It’s what happens downstream of reuptake inhibition over weeks that bring about the benefits**

The idea that supplementing with a precursor to raise serotonin will lead to elevated mood is one of the most persistent oversimplifications in consumer neuroscience.

No neurotransmitter works alone. Each is held in check by the others.

The post-lunch dip is a circadian phenomenon, not a pathology.

Core body temperature and subjective alertness both fall in a predictable trough roughly seven to nine hours after waking, independent of what you ate. It was present in adolescence too but it was simply masked by higher baseline arousal.

Low-stimulation, sedentary tasks remove that masking, which is why the same physiology becomes conspicuous in your thirties.

Bright light exposure, movement, or a really short nap address it more reliably than additional caffeine.

Collagen is technically a protein. It’s just not the type that does the things that most people are counting protein for. 

If a significant share of your daily intake is collagen, your logged protein and your usable protein have diverged, and your tracking app won’t tell you that, because none of them model amino acid profile.

You can’t measure a signal in a noisy room.

And if you lowered the noise in that room, maybe you’d be less fixated on measuring a new signal anyway.

My last post was about protecting your reserve capacity: becoming more discerning about the unnecessary demands that leave you with less capacity for the challenges that matter.

But protecting capacity and expanding capacity are not quite the same project.

Reserve capacity is not one generic pool of energy. It is the spare functional range available across multiple systems when demand rises.

Your cardiovascular system has reserve. Your mitochondria have respiratory reserve. Your muscles have force-producing reserve. Your thermoregulatory system has additional heat-producing capacity. Even your response to psychological threat can become better calibrated through graded challenge and successful recovery.

The practical implication is specificity.

And adaptation requires a sufficiently specific signal, repeated at a recoverable dose, with enough time and resources to build from it.

Protect your energy.

Then decide what you are protecting it for.
