What do people do once GLP-1 medications succeed at weight loss?

The drugs have been adopted by 1 in 8 Americans, with many achieving their prescribed weight loss. They now face the question of how to keep the weight off, the key issue with any weight loss program that researchers have known about for decades. Each case is unique. Some folks continue to use GLP-1s like Ozempic in minuscule doses, while others taper them off over time.

In 2023, Americans spent more than $50B on weight loss drugs, a number expected to triple or more by the end of the decade.

Risks of GLP-1s include health side effects, counterfeit drugs, and more

This episode interviews researchers and patients who have used semaglutide to explore some of the potential risks associated with using the drug to lose weight. These include insurance challenges, health scares related to counterfeit versions of these drugs, and some users lose their ability to enjoy food.

GLP-1s are linked to reduced worker illness and cost savings—a 2026 economic analysis finds the weight-loss drugs are tied to a 17% drop in worker sick leave days.

Debunking myths about weight loss drugs

Business Insider delves into the research on GLP-1 to highlight the good and bad aspects other stories overlook. Few make it clear that GLP-1 drugs simply don’t work for many people. This deep dive raises a number of questions about the future of GLP-1 and how they will be used.

GLP-1 drugs are under investigation for treating Alzheimer's, Parkinson's, and drug addiction

Researchers are investigating GLP-1 applications for a variety of chronic conditions. One area of interest stems from how study participants using GLP-1 for diabetes and obesity reported describing less longing for wine and cigarettes while taking the medication—intriguing researchers about using the drugs for addiction applications. The drug, they theorize, could bind to receptors that mediate desire. (Some users may experience a paywall.)

GLP-1 helps reduce obesity through a number of mechanisms

Clinical studies show GLP-1 drugs, including semaglutide, promote weight loss through a number of effects. These include reduced appetite, slower emptying of the digestive tract, increased insulin production, and more.

Food companies are exploring 'GLP-1 friendly' diet labels

Producers of foods like Healthy Choice frozen meals are placing "GLP-1 friendly" labels on their food, but there's no regulation about what that label means. Nutritionists say that GLP-1s can help reduce appetite, but healthy, balanced diets are a necessary complement to the medications. Data shows that about half of GLP-1 users quit these medications within a year and then rapidly regain weight, underscoring the importance of also prioritizing healthy eating.

Diabetes drug GLP-1 is a peptide (that's what the 'P' is for).

Weight Watchers began offering access to GLP-1 weight-loss medications in 2023 after losing more than 1.5 million members over the previous two years.

A 201-level at how GLP-1 drugs lead to appetite reduction

It's well-established that drugs which mimic the hormone GLP-1 can help people lose weight and control blood sugar levels, primarily through appetite reduction. This technical review provides an overview of how both natural and therapeutic GLP-1 interacts with the gut and brain to produce its effects.

Not everyone who is a candidate for GLP-1 is choosing to use the drug

One person writes about why, although she's a good fit for the medication on paper, she's decided not to take GLP-1 due to concerns about mental health and other side effects, among other reasons.

Semaglutides, which belong to a class of drugs called GLP-1s, are prescribed for weight loss in combination with diet and exercise because they trigger the release of the appetite-suppressing hormone incretin.

GLP-1s are netting interest for treating autoimmune diseases, but are considered experimental

Already used to treat type 2 diabetes, the novel medications are showing some early promise in experimental studies at reducing inflammation and treating autoimmune conditions including rheumatoid arthritis and inflammatory bowel conditions. But researchers caution that side effects are still under investigation—rarely the medication has caused lupus, an autoimmune disease.

Can you microdose GLP-1 agonists like Ozempic?

GLP-1 agonists like Ozempic can help with weight loss, diabetes, and anti-inflammation. For some users, normal doses are too much. So, they've started "microdosing"—taking a smaller amount than the lowest increment of the drug available. While not yet backed by clinical trials, some doctors observed positive effects for certain people.

Read the FDA's statement on concerns over compound pharmacies

GLP-1 drugs popularity for weight loss and treating diabetes, led to a significant supply shortage and the rise of compound pharmacies, which produce customized drug formulations but lack formal approval from regulators. The drugs are ostensibly the same, but manufacturing methods lead to variations in concentration, filler compounds, and more.

GLP-1 drugs mimic a natural hormone that triggers appetite-suppressing effects

Ozempic, one of the brand names for the drug semaglutide, was originally developed in 2012, to help treat Type 2 diabetes. Among other effects, the drug mimics a naturally produced hormone known as GLP-1, which is released while eating to let our bodies know we are full.

The lack of guidance on getting off GLP-1s leaves patients at risk

Dr. David Kessler, former FDA Commissioner and public health leader, explores how these drugs override the brain’s reward-driven eating habits but have notable side effects. These include developing eating disorders, muscle loss, and intestinal obstruction.

GLP-1s may lower inflammation, possibly helping to combat cognitive decline

An analysis of existing GLP-1 research, published in April 2025, indicated that GLP-1 drugs reduce inflammation, with numerous health benefits. The work notes that GLP-1s were linked with a statistically significant reduction in dementia in randomized clinical trials.

GLP-1s may weaken the effectiveness of birth control and affect other medications, hindering how and when they circulate through the blood.

Tirzepatide: A GLP-1 drug that also acts on separate receptors to promote weight loss

Tirzepatide, like semaglutide, is a GLP-1 drug used in diabetes treatment and for weight loss. Unlike semaglutide, it also acts on glucose-dependent insulinotropic polypeptide receptors, proving a second route to reducing appetite as a means to treat diabetes and promote weight loss.

Peptides like GLP-1 account for 31 of 370 new drugs approved by the US FDA between 2016 and 2023.

How semaglutides are both better and worse than we know

The drugs were developed for use treating diabetes and, later, weight loss, but they have proven helpful with the heart, kidneys, and colon. On the flipside, it may slow digestion and lead to gastroparesis, or stomach blockages, and unexpected babies resulting from the slow effect of birth control pills.

GLP-1 drugs, first used to manage diabetes, were derived from Gila monster saliva.

The popularity of new weight loss drugs has led to a diabetes treatment shortage

The FDA approved Ozempic to help patients with diabetes, but the popularity of semaglutide as a weight loss drug led doctors to prescribe Ozempic to nondiabetic patients who needed to lose weight. Ozempic became so popular that manufacturers could not keep pace with demand, posing risks for Ozempic-users with diabetes.

How weight loss drugs could reduce obesity costs

A detailed analysis from finance giant ING finds semaglutide and other weight loss drugs could significantly drive down global costs stemming from heart disease and other health problems associated with obesity. The benefits will vary, depending on each country’s demographics and drug and healthcare costs.

Medicare doesn’t provide coverage for outpatient prescription drugs

How to properly use semaglutides

This podcast with a nutritionist and a medical doctor discusses how useful semaglutide can be for weight loss. It also outlines the need for patients to set reasonable expectations and to make changes to both diet and exercise as part of an overall weight management strategy. The experts note that failure to make meaningful changes outside of using semaglutide may mean patients need to stay on the drug in order to keep the weight off.
