Prescribed on cardiovascular grounds rather than for weight, and almost everything written for patients assumes the opposite.

Relative versus absolute is the distinction that gets lost: a 20% relative reduction on a high baseline risk is a large absolute benefit, and the same relative figure on a low baseline risk is a small one.

So the question, as narrowly as I can put it: how much of the SELECT benefit is plausibly independent of the weight loss, and whether that distinction changes anything practical.

Tell me what I have not thought of.

Short answer first, then the reasoning. Albumin binding above 99% is the whole reason weekly dosing works, and it is also why the trough matters more than the peak. People who dose late are not losing a peak, they are letting the trough fall, and the appetite effect tracks the trough.

All true, with one condition: that curve is for people who reached the dose on schedule. Anyone who slowed the ladder for tolerability is on a different, flatter curve, and comparing yourself with the published mean will make you feel like a non-responder when you are not.

Agreed, though "tolerable" needs defining. A dose you tolerate by eating almost nothing is not tolerated, it is being paid for somewhere else — usually in lean mass, sometimes in adherence three months later.

If somebody has the primary source to hand I would rather cite it than paraphrase it.

From the other side of the consultation, briefly.

Vitamin deficiency cascade with cardiovascular risk: after 6+ months of reduced food intake, I developed a subtle but important pattern: low B12 → elevated homocysteine → increased cardiovascular risk marker.

The connection: B12 is a cofactor for homocysteine metabolism. Without adequate B12, homocysteine accumulates. This is ironic — taking a CV-protective medication while developing a CV risk factor from reduced nutrition.

Solution: comprehensive vitamin supplementation and regular lab monitoring. Don't let the medication's benefits be undermined by nutritional deficiencies.
