Why This Medication Changes the Rules

GLP-1 medications work partly by slowing gastric emptying — food stays in your stomach longer, which is a big part of why you feel full on less. The tradeoff is that your fullness signal now arrives later than it used to, and later than your eating pace might expect.

Eat at your old speed, and you’ll blow past comfortable fullness before your body has a chance to tell you to stop. That’s when patients report the nausea, bloating, and reflux that get blamed on the medication, when the real cause was often the pace of the meal.

The 80% Rule

A simple, practical target: stop eating when you feel about 80% full — comfortably satisfied, not stuffed. This is a behavioral habit, not a precise clinical threshold, but it’s a genuinely useful one on this medication specifically, given how the delayed-emptying physiology works.

How to Actually Slow Down

Put your fork down between bites. Chew fully before your next bite. Give a meal at least fifteen to twenty minutes before deciding whether you need more. Most patients who make this one adjustment report meaningfully fewer GI symptoms within the first couple of weeks.
