Using GLP-1s

DPP-4

Dipeptidyl peptidase-4, the enzyme that rapidly breaks down the body's own GLP-1 within minutes.

By the glp1.how editorial teamReviewed

DPP-4 (dipeptidyl peptidase-4) is an enzyme that rapidly degrades the body's own GLP-1. Native GLP-1 has a half-life of only about one to two minutes, largely because DPP-4 breaks it down so quickly (Victoza prescribing information (external link), section 12).

GLP-1 receptor agonist medications are engineered to resist this enzyme, which is what lets them stay active in the body far longer than natural GLP-1 does.

  • Can you boost GLP-1 naturally? How food and lifestyle compare to the medications · You can raise your own GLP-1 with protein, fermentable fiber, and exercise, and that part is real. What doesn't hold up is the implied equivalence with the medications. This guide covers what nudges your natural GLP-1, why your body clears it in minutes while the drugs hold it for a week, and why "natural boosting" works as a foundation for treatment and can't replace it.
  • How GLP-1 medications work, in plain language · Semaglutide and tirzepatide copy hormones your gut already makes after a meal. This guide explains what those hormones do, why the medications quiet hunger and 'food noise,' what the second hormone in tirzepatide adds, and how the same signal that cuts appetite can also cause nausea.
  • Gastric emptying on a GLP-1: how much slower, how long it lasts, and what it means for gastroparesis · GLP-1 medications slow the stomach, but the trials show the effect is smaller and fades more than most people assume, especially with the long-acting weekly drugs. This guide covers how much slower, whether it lasts, how gastric emptying is measured, how it differs from gastroparesis, and why the "food ferments in your stomach" claim has no evidence behind it.
  • Restarting a GLP-1 after a missed stretch: what each drug's label says about re-titration · Missed a few weeks of Wegovy, Zepbound, Ozempic, Trulicity, Saxenda, or a GLP-1 pill? Only four labels spell out when to restart at a lower dose: Wegovy injection after 2 missed weekly doses, Saxenda and Victoza after more than 3 days, and Foundayo after 7 missed daily doses. The rest are silent on long gaps. This by-drug reference separates what each label says from what's left to your prescriber, and explains why going straight back to your old dose is risky.
  • Comparing the GLP-1 pills: Ozempic tablets (Rybelsus), the Wegovy pill, and Foundayo · There are now three GLP-1 pills in the US, and they aren't interchangeable: oral semaglutide for diabetes (Rybelsus, now sold as Ozempic tablets), oral semaglutide for weight (the Wegovy pill), and orforglipron (Foundayo). Here's how they compare on approval, how you take them, what the trials found, side effects, cost, and what you give up versus a weekly injection.
  • Every key GLP-1 clinical trial: what it tested, who paid for it, and what it found · STEP 1, SURMOUNT-4, SELECT, LEADER: GLP-1 trial names get quoted everywhere, usually without context. This reference page lists 205 named, completed GLP-1 trials in one place, grouped by drug and by question, with what each one tested, who sponsored it, its headline result, and a link to the published paper. It also lists the trials that finished but have not reported, and shows who paid for the research.
