A good GLP-1 newsletter can save you hours of scrolling through forums and comment threads, and The GLP-1 Effect is one of the most useful we have come across. It is written by Lucas Veritas, who describes it as a free, science-backed resource for people on medications like Ozempic, Wegovy, Mounjaro and Zepbound. His archive now runs to more than 70 posts, which is a lot to take in if you have only just found it.
So we went through his own list of most-read posts and picked five that we think are worth your time. We chose practical pieces that help you understand what is happening and ask better questions, rather than posts that tell you what to do with your dose. Below, you will find a short summary of each one and a link to read it in full on The GLP-1 Effect.
One note for transparency: we are in touch with Lucas, and his newsletter and the Pep blog are featuring each other. The five picks and the summaries are our own.
Why Read a GLP-1 Newsletter at All?
Your prescriber covers the medical side, but appointments are short. Meanwhile, most day-to-day questions come up at home: what to eat when nothing sounds good, whether a stall is normal, or what a new study really means. A well-run newsletter fills that gap in a few ways:
- It translates research. Long studies get turned into plain language you can read in five minutes.
- It collects what works. Practical tips from many people end up in one place, instead of scattered across social media.
- It arrives on its own. You do not have to go looking, so you keep learning even in a busy week.
However, no newsletter knows your health history. Therefore, treat what you read as background and as a source of questions for your care team, not as instructions.
5 Posts From The GLP-1 Effect Worth Reading
1. 33 One-Sentence Tips for Beginners
If you are in your first month, start with 33 One-Sentence Tips for Beginners. As the title suggests, each tip is a single line, so you can read the whole thing over a coffee. It covers the basics that people often wish they had known on day one: taking photos and measurements before you start, drinking more water than you think you need, eating protein and fiber regularly, keeping up a simple walking habit, and not comparing your results with anyone else’s. It is a quick, friendly checklist rather than a deep dive. For more detail on the early weeks, pair it with our own tips for new GLP-1 users.
2. Protein: 7 Key Questions Answered
Protein is the nutrition topic that comes up most on these medications, and Protein: 7 Key Questions Answered handles it in a clear question-and-answer format. Lucas explains the commonly cited intake ranges, why spreading protein across the day matters, and what to try when your appetite is too low for a full meal. In addition, he shares a handy label trick for spotting foods that are truly high in protein, and he makes the case for whole foods over living on shakes. Your own target depends on your body and your health, so check it with your clinician. For a starting estimate to bring to that conversation, try our free GLP-1 protein calculator, and see our guide to GLP-1 muscle loss for the strength-training side.
3. Weight Loss Plateaus: The Science Explained
Almost everyone hits a stall, and it tends to feel personal when it happens. In Weight Loss Plateaus: The Science Explained, Lucas reframes it. He walks through set-point theory, which is the idea that your body defends a weight range and needs time to accept a new, lower one. As a result, a plateau looks less like failure and more like a normal part of the process. The post is short, well referenced, and reassuring without being fluffy. When you are ready for practical next steps, our GLP-1 plateau guide covers what to review with your prescriber.
4. Big Semaglutide Study Deep Dive: 28 Benefits, 16 Risks
This is the research explainer of the bunch. Big Semaglutide Study Deep Dive breaks down a large 2025 analysis from researchers at the VA St. Louis Health Care System, published in Nature Medicine. The study followed close to two million U.S. veterans with diabetes and compared people who started a GLP-1 medication with people on other treatments across 175 health outcomes. Lucas sorts the findings into two readable lists. On one side are outcomes that were less common in the GLP-1 group, including several heart, brain and infection-related conditions. On the other are outcomes that were more common, such as digestive problems, kidney stones and pancreatitis. Keep in mind that the study was observational and looked at veterans with diabetes, so it shows associations rather than proof of cause. Even so, it is one of the widest views of these medications so far, and his summary makes it easy to follow.
5. Maintenance Mode: What Happens After You Reach Your Weight Goal
Most GLP-1 content is about losing weight. Far less is written about what comes next, which is why Maintenance Mode stands out. Lucas describes the mental shift from chasing progress to protecting it, and he is honest about the worries that come with it, such as fear of regain and the long-term cost of treatment. He then reviews several studies on what helps people hold their results, including the role of regular exercise alongside medication. If you are close to your goal, it is a thoughtful read. Our guide to stopping GLP-1 medication covers the related question of what tends to happen if treatment ends.
How to Get More From Any GLP-1 Newsletter
Reading is a good start. However, advice lands better when you can check it against your own experience. A few habits help:
- Read with your own data nearby. A post about plateaus is far more useful when you can see your actual weight trend. If you log doses, weight, protein and side effects, you can track it free with Pep.
- Turn tips into questions. If something sounds relevant, write it down and raise it at your next appointment.
- Check the date. Prices, coverage rules and approvals change quickly, so look at when a post was last updated.
- Leave dosing to your prescriber. Any change to how much you take, or how often, is a decision for your care team.
GLP-1 Newsletter FAQ
Is The GLP-1 Effect newsletter free?
The GLP-1 Effect describes itself as a free resource, and the five posts above were all open to read on its website when we published this roundup.
Can a GLP-1 newsletter replace advice from my doctor?
No. A GLP-1 newsletter is a helpful way to learn the background and feel less alone, but it cannot account for your health history, other medications or lab results. Always confirm changes with your prescriber.
Which post should I read first?
If you are new, begin with the 33 one-sentence tips, because it is the quickest overview. If you have been on treatment for a while, the plateau and maintenance posts will probably feel more relevant.
