Micronutrient adequacy at low total intake — does this still hold?

Micronutrient adequacy at low total intake — does this still hold? — that is the question, and I have not found it answered plainly anywhere I have looked.

Collecting what is known about Micronutrient adequacy in one place, because it is currently spread across a category, two tag pages and a thread that is hard to find.

This is a summary rather than new work, and I have attributed each part to where I found it.

I had written a reply contradicting the opening post and deleted it. Here is what survived.

Two claims get bundled together under Micronutrient adequacy and they need separating. The descriptive one — this is what was observed — is usually well supported. The causal one — this is why — usually is not.

Almost every disagreement in threads like this one dissolves once you say which of the two you are making.

Adding the measurement that the opening post says would settle it.

Distribution across the day appears to matter less than total for most outcomes, and it matters practically because a single large meal is harder when appetite is reduced.

The mechanism is plausible, which is not the same as established.

Protein supplements: whey, casein, and plant-based protein powders can help hit targets when whole-food intake is limited by appetite. Protein quality (all essential amino acids) matters more than form.

That is the version I use. It may not be the version that is correct.

That is consistent with mine, for whatever one more account is worth.

Picking up post #4: that is the part I would want checked first.

I changed my mind about Micronutrient adequacy after someone here asked me for the source and I could not produce one. That is worth saying out loud because it is the ordinary way it happens.

On post #7 — agreed on the reasoning, with one qualification.

What would change my mind on Micronutrient adequacy is a second dataset collected by someone with no stake in the first. Until then I hold it loosely and I would rather say so than pretend to more.

Micronutrient adequacy becomes a real question at very low total intake and is much less discussed than protein.

The reasoning is more useful than the number, which is why I have shown it.

Timing of protein: spreading protein intake across the day, with some at each meal, is more practical than trying to hit the whole target at one sitting on suppressed appetite.

That is the honest state of it as of this week.

Density matters more than quantity when total intake is limited. The same protein in a smaller volume is the whole game.

Anyone with a larger sample, please post it.

Fibre: adequate fibre intake supports fullness and gut motility, both of which matter during the gastrointestinal effects of these compounds. High fibre on top of appetite suppression requires attention to hydration and gradual introduction.

I have seen it go both ways, which is why I hedge.

Everything in post #9 holds. The case it does not cover is the one I have.

Where intake has fallen a long way, protein is usually the first thing to fall because it is the least appealing macronutrient when appetite is reduced.

Fine by me. I had wanted a stronger conclusion and there is not one available.
