Dietary Fiber
The indigestible plant matter that feeds satiety, steadies glucose, and counters GLP-1 constipation.
Fiber is the plant material human enzymes can't break down — soluble forms gel and slow absorption, insoluble forms add bulk and speed transit — and most adults eat half the recommended 25–38 grams. Its weight relevance is triple: fullness per calorie, flattened glucose curves, and a gut microbiome that itself produces GLP-1-stimulating compounds.
On medication it takes on a fourth job: countering the constipation that slowed transit plus smaller meals produce. The climb should be gradual with water alongside (fiber without fluid worsens the problem it solves); food sources — vegetables, beans, berries, oats — beat supplements, with psyllium as the respectable bridge. "Protein first, plants beside" covers most of nutrition during treatment in five words.
