Weight Loss Pills: Foundayo vs Wegovy

So last week, a patient sat down in my office, right, pulled like her phone and said, Doc, you know, I saw a video. There's a pill now. Actually, two pills. Which one do I take? And can I stop my shot? Well, she's talking about the GLP-1, weight loss injections and whatnot, right? And now there are pills. And wait, can I just take your berberine instead? You know three questions in eight seconds, very efficient. I respect it. My patients are great asking questions and honestly those are the three questions I'm getting every single day. So let's do this properly. Who am I? I'm Dr. Ahmet Ergin. I am an endocrinologist at the Diabetes, Thyroid and Hormone Center of the Treasure Coast in Port St. Lucie, Florida and now we have an office in Vero Beach. Today we are going deep on the new GLP-1 weight loss pills, Fondayo versus Wegovy, right? What the studies actually show, side effects, cost, who should take, which and where lifestyle and supplements like berberine may be fit. It's a long one, but grab a coffee, you know, black coffee, maybe, you know, no sugar. I'm watching you. Okay, so first, what are we even talking about? GLP-1 is a hormone your gut makes when you eat. It tells your pancreas, Hey, food's coming. Release some insulin. It tells your liver, Calm down. Stop dumping sugar. It slows your stomach so you feel full longer. And it talks to your brain, the appetite center, and turns down the volume on what people now call food noise. That constant. Is there chocolate in the house? There's chocolate in the house. I know there's chocolate in the house. Drugs like Ozempic, Wegovy, Monjaro, Zepbound, they copy or amplify that hormone. And until recently, almost all of them were shots, once a week, in the belly or thigh. Now we have pills, two big ones for weight loss. The first is the Wegovy pill. That's oral semaglutide, the same molecule as Ozempic and Wegovy injections, just in a tablet. FDA approved it on December 22, 2024 for weight management, and, this is important, it also carries an indication to reduce the risk of heart attack, stroke, and cardiovascular death in adults with overweight or obesity and established heart disease. Same as the Wegovy shot. The second is Foundio. The generic name is Orforglipron, which, I'm sorry, sounds like a Lord of the Rings character. Orforglipron, son of Glipron. Eli Lilly makes it, and the FDA approved it April 1st, 2026. Not a joke, despite the date. And here's the interesting part. Fondayo is not a peptide like semaglutide. It's what we call a small molecule. Why do you care? Because peptides are fragile. Your stomach acid wants to destroy them. So the semaglutide pill needs a special absorption enhancer, and it needs very strict rules. Empty stomach, small sip of water, Wait 30 minutes before you eat or drink anything else or take other pills. Fondayo doesn't need any of that. You can take it with or without food, any time of day. That's a big deal for real life. I mean, I have patients who can't remember whether they took their pill, let alone whether they waited 30 minutes. Okay, part everybody wants to know. How much weight do people actually lose? Let's start with the Wegovy pill. The main trial is called Oasis 4, 64 weeks, a 25 mg daily dose versus placebo in adults with obesity or overweight with health problems, not diabetes. Two ways to read the results, and I want to explain this because it trips people up. If you count everybody who started, including people who quit, forgot pills, whatever, the semaglutide pill group lost about 13.6% of their body weight. Placebo lost about 2.4%. If you look only at people who actually stayed on the drug the whole time, it was about 16.6% versus 2.7%. So for a 220-pound person, We're talking roughly 30 to 36 pounds, on average. And about 3 out of 4 people on the pill, 76 out of 100, lost at least 5% of their weight. On placebo, about 31 out of 100 did that just from, you know, diet advice and being in a study. Now Foundio. The big trial is called ATTAIN-1. 72 weeks. More than 3,000 adults with obesity or overweight. Also without diabetes. Three doses tested, 5.5, 9, and 17.2 milligrams. At the top dose, 17.2 milligrams, counting everyone who started. People lost about 11.2% of their weight versus 2.1% on placebo. Among people who stayed on it, it was about 12.4% versus 0.9%. And in absolute numbers, and you know I love absolute numbers, About 55 out of 100 people on the top dose lost at least 10% of their weight. On placebo, about 13 out of 100. And 36 out of 100 on the top dose lost at least 15%. Versus about 6 out of 100 on placebo. So... If you line them up side by side, and I have to be careful here because these are different trials, different people, different lengths, the Wegovy pill looks like it produces a bit more weight loss on average. Roughly 14% versus 11%, if you count everybody. We don't have a head-to-head trial yet, so I'd say the semaglutide pill may be somewhat stronger. Foundio is much easier to take. That's the trade-off in one sentence. And for context, the shots are still the heavyweights. Tirzepatide, the Zepbound shot, produces more weight loss on average than either pill. So if someone needs the maximum effect, very high BMI, serious complications, the injection may still be the better tool. Pills are about convenience, needle-free options, and, potentially, access. What about blood sugar, since this is SugarMD? Foundio isn't approved for type 2 diabetes yet. It's being studied. But in the diabetes trials, it lowered A1c by about 1.2 to 1.6 points versus placebo, depending on the dose. That's a meaningful drop. Oral semaglutide, as Rybelsis, has been used for diabetes for years. Okay, side effects. Let's be real. These are GLP-1 drugs. The side effects are mostly in the gut. Nausea. Vomiting. Diarrhea. Constipation. Sometimes all four in the same week. Which is impressive, honestly. In a terrible way. In ATTAIN-1, at the doses they used, nausea hit roughly 29 to 36 out of 100 people, versus about 10 out of 100 on placebo. Vomiting, about 13 to 24 out of 100, versus about 4 on placebo. Constipation, 22 to 30 out of 100, versus about 9. Most of it was mild to moderate, and it happened mostly when the dose was being increased, which is why we go up slowly. Start low, go slow. Every endocrinologist's favorite phrase. And how many people quit because of side effects? At the top dose of Foundio, about 10 out of 100 people stopped because of adverse events, versus about 3 out of 100 on placebo. So, most people tolerate it, but not everyone. The Wegovy pill's side effects look a lot like the Wegovy shots. Nausea, diarrhea, vomiting. Then there are the less common but important class warnings. Pancreatitis. If you get severe belly pain going to your back, that's an ER trip, not a let's wait and see. Gallbladder problems, especially with fast weight loss. Dehydration, which can hurt your kidneys if you're vomiting a lot. Low blood sugar if you're also on insulin or sulfonylureas like glipizide. And, I mention this every time, slowed stomach emptying can change how other pills are absorbed. Thyroid pills, birth control, some others. So if you're on levothyroxine, recheck your TSH after you start. I literally just did a whole video on that. There's also the thyroid C-cell tumor warning on the semaglutide products, from rodent studies. If you or your family have medullary thyroid cancer, or MEN2, these aren't for you. Hashimoto's alone is different. Now here's the thing that keeps me up at night. Not literally. Okay, sometimes literally. What happens when you stop? We have good data on this from the injection version of semaglutide. In the Step 1 trial extension, when people stopped semaglutide after a year, they regained about two-thirds of the weight they'd lost within the following year. Two-thirds. Within a year. So, and I say this with love, These medicines are not a car wash. You don't go through once and come out clean forever. For most people, they work while you take them. It's more like blood pressure medication. You take it, the pressure's good. Stop, it comes back. Which is exactly why, and you knew I was going to say this, what you build while you're on the drug matters so much. So let's talk about the foundation, because if I'm being honest, and I always try to be, lifestyle is not the boring part. It's the part that decides whether you keep the weight off, whether you keep your muscle, and whether you need the drug forever. Number one, protein. When you lose weight fast, you lose fat. Great. But you also lose muscle. And muscle is your glucose sponge. It's where sugar goes after a meal. Lose muscle, and your metabolism gets worse, not better. So I want protein at every meal. Many experts suggest something like 1.2 to 1.6 grams per kilogram of body weight a day during weight loss. Your doctor can help I can help you personalize that, especially if you have kidney disease. Number two, resistance training. Two to three times a week. Bands, weights, body weight, doesn't matter. Squats from a chair count. I'm not asking you to become a bodybuilder. I'm asking you to tell your muscles, hey, we still need you. Number three, the post-meal walk. 10 minutes after your biggest meal. It's one of the most underrated tools in diabetes. Your muscles pull sugar out of your blood without needing as much insulin. And if you wear a CGM, Like in my last video, you can literally watch it work. Number four, food order. Vegetables and protein first. Carbs last. Small trick, real effect on post-meal spikes. Number five, sleep. Bad sleep makes you hungrier and more insulin resistant. No pill fixes a four-hour night. And here's the evidence that lifestyle is real medicine. The Diabetes Prevention Program, the DPP, took people with prediabetes. In the placebo group, about 11 out of every 100 develop diabetes each year. In the intensive lifestyle group, about 7% weight loss and 150 minutes of activity a week, it was about 5 out of 100. Metformin was about 8 out of 100. So lifestyle beat the drug. That was 2002, and it's still one of the most important studies in the field. Okay, the third question from my patient. Can I just take your berberine instead? And I have to answer this one carefully, because I make it. So you should be a little skeptical of me. That's healthy. Short answer, no. Berberine is not a GLP-1 pill. It's not going to make you lose 14% of your body weight. Anyone who tells you berberine is nature's ozempic, that's marketing, not medicine. I don't say that. Here's what berberine does do. It activates AMPK. That's the cell's fuel gauge, the same pathway metformin works on. When AMPK turns on, your muscles take up more glucose. Your liver makes less sugar. And your cells get more insulin-sensitive. And the evidence is decent. A 2022 meta-analysis in Frontiers in Pharmacology pooled 37 randomized trials with about 3,000 people with type 2 diabetes. Berberine lowered A1c by about 0.63 points on average, fasting glucose by about 15 mg per deciliter, and post-meal glucose by about 21 mg per deciliter. And side effects overall weren't higher than control. Most of the trials were small, and a lot were done in China, so the certainty is moderate, not perfect. Our SugarMD Super Berberine uses dihydroberberine, which is better absorbed than regular berberine, so you can use a lower dose and, for many people, get fewer stomach issues. So where does it fit? Three places. One, if you have prediabetes or early type 2, and you're working on lifestyle and you're not ready for, or don't need, A prescription. Two, if you're on a GLP-1 and you want extra support on the glucose side, talk to your doctor, especially if you're on insulin or sulfonylureas, because you don't want lows. Three, maybe, and I want to be clear that we don't have great trials on this yet. As part of a plan after you come off a GLP-1, alongside the lifestyle habits you built, that's a reasonable idea, but it's not proven. So I won't oversell it. Okay, money. Because nobody can take a medicine they can't afford. Zepbound Self-Pay starts at $149 a month at the lowest dose through Lilly Direct. Higher doses cost more. With commercial insurance and the savings card, eligible patients may pay as little as $25. Medicare Part D. Eligible patients may pay $50 a month starting July 2026. The Wegovy Pills starting dose also launched with savings offers around $149 a month. Prices change constantly. And insurance coverage for weight loss is still a mess. So check current pricing before you decide. Don't trust a YouTube video from six months ago. Including this one. Okay, let me think out loud like I would in clinic. Not a rule, just how I reason through it. If you want the most weight loss from a pill, and you can handle the morning routine, empty stomach, small sip of water, wait 30 minutes, the Wegovy pill may be a good fit. And if you have established heart disease, it has that cardiovascular indication, which matters. If your life is chaotic, shift work, kids, you take 10 other pills in the morning, you're on levothyroxine and you're tired of the empty stomach dance, Foundio's no-rules dosing is genuinely attractive. Slightly less weight loss on average, much simpler. If you need maximum effect, very high BMI, serious complications, honestly, the injections, especially tirzepatide, are still the strongest tools we have. If you have prediabetes or mild insulin resistance and you're not a candidate for these, lifestyle first, a CGM to learn your patterns, and something like super berberine is a very reasonable starting point. And if you're pregnant or planning pregnancy, or you have a history of pancreatitis or medullary thyroid cancer, different conversation. We need to talk. Okay, before I wrap up, let me hit a few questions from the comments on my last GLP-1 videos. Rapid fire. Let's see how rapid I can actually be. Historically, not very. Can I switch from my shot to a pill? Sometimes, yes, but it's not a one-to-one swap. The doses are completely different, and you may need to restart lower and work back up. Please don't do this on your own. Talk to your prescriber, because switching wrong is a great way to spend a weekend hugging the toilet. Can I take these with metformin? In general, yes. They're commonly used together in type 2 diabetes. Metformin plus a GLP-1 is a very standard combination. The bigger concern is insulin or sulfonylureas, where the doses may need to come down so you don't go low. Will I lose muscle? You might. Any fast weight loss can take some muscle with it. That's why I spent so long on protein and strength training. It's not optional. It's the whole game. What about ozempic face? That's not a drug side effect exactly. It's what happens to the face with rapid fat loss, especially as we get older. Slower, steadier weight loss and keeping muscle seem to help. Your face will thank you. So will your knees. Is it okay if I only lose 8%? Yes! Honestly, yes. Even 5-10% weight loss can meaningfully improve blood sugar, blood pressure, and fatty liver. You don't need to look like a fitness influencer for this to be a win. Most fitness influencers don't look like that either, by the way. It's lighting. Do I have to take it forever? Maybe. Maybe not. For a lot of people, it's long-term. Like blood pressure medicine. For some, after building really solid habits, we can try lowering the dose and watching closely. That's a decision we make together. With data, not one you make because you ran out of refills. Here's my honest take after all of this. These pills are good news, real good news. More options, no needles, potentially better access. And that matters for millions of people. And you may, you might think differently. It may not work for you. And they're definitely not magic. They are tools, right? They work best and the results last longest when they sit on top of good habits. Protein, strength training, walking, sleep. And when somebody is actually monitoring you, your labs, thyroid, if you're on thyroid medicine, et cetera, your muscle, your blood sugar, Very important. And please, please, do not buy these online from sketchy websites. Compounded or counterfeit GLP-1 products are a real problem. Get them through a legitimate prescriber and a legitimate pharmacy that is not online.
