Appetite Regulation
Balancing of hunger and satiety hormones (ghrelin, leptin) supporting appropriate caloric intake and preventing overeating. Influenced by fiber, protein, and certain supplements.
TL;DR
Appetite is governed by ghrelin, leptin, GLP-1 and blood-sugar stability. Protein, viscous fibre and adequate sleep do most of the work; glucomannan and berberine offer modest additional help.
Why It Matters
Dysregulated appetite drives most weight regain after dieting, because energy restriction raises ghrelin and lowers leptin for months afterwards. The clinically meaningful levers are macronutrient composition, meal timing, sleep duration and fibre intake. Supplements act at the margin. Sudden appetite loss or a marked unexplained increase deserves medical evaluation rather than self-treatment.
How to Measure
Rate hunger and fullness on a 0-10 visual analogue scale before and two hours after meals for a week. Useful labs: fasting insulin and glucose with HOMA-IR, HbA1c, leptin where available, and TSH. Continuous glucose monitoring can expose the post-meal crashes that trigger snacking.
Biomarkers
Optimization Protocol
Anchor each meal with 25-40 g protein and 8-10 g fibre; this alone changes satiety more than any supplement. Sleep 7-9 hours, since short sleep raises ghrelin and lowers leptin within two nights. Front-load calories earlier in the day. Supplement layer: glucomannan 1 g with 250 mL water 30 minutes before meals, psyllium 5-10 g/day, berberine 500 mg twice daily for those with insulin resistance, and correct low vitamin D and iron, both of which distort appetite signalling.

Typical Timeframe
Protein and fibre changes shift hunger ratings within 3-7 days; insulin-sensitising effects of berberine take 8-12 weeks.
