One of the strangest things about taking a GLP-1 medication can be realizing that you're simply not thinking about food the way you used to.

Breakfast comes and you're not particularly hungry. You get busy, lunchtime passes, and suddenly it's mid-afternoon and you've barely eaten. Or you make the same dinner you've eaten a hundred times, sit down with what used to be a completely normal portion, and after a few bites you're done.

Medications commonly discussed in the GLP-1 conversation include Ozempic, Wegovy, Mounjaro and Zepbound, although they don't all contain the same medication or have the same approved uses. What they can have in common is a pretty dramatic change in appetite and how quickly you feel full.

Eating less may be part of the experience, but your body hasn't stopped needing protein, vitamins, minerals, fibre and fluids. That's why GLP-1 nutrition deserves a little attention of its own.

The goal isn't to create another diet with a long list of rules. It's to make the food you are eating count, especially on the days when there isn't much room for it.

One thing I really don't love about some of the GLP-1 conversations online is how much attention is paid to eating less and how little is paid to eating well.

Research has found that people taking GLP-1 medications can substantially reduce the amount of food they eat. A major 2025 nutrition advisory reported reductions in calorie intake of approximately 16% to 39% in GLP-1 studies. When there's considerably less food coming in, it makes sense that there may also be fewer opportunities to get the nutrients your body needs.

That doesn't mean taking a GLP-1 automatically gives you a vitamin deficiency. It means this is probably not the time to make how little can I eat? the goal.

Instead, start looking at what's making it onto the smaller plate.

Current expert guidance has identified nutrients including iron, calcium, magnesium, zinc and several vitamins as ones that may deserve attention when food intake becomes very low. The answer isn't to run out and buy every vitamin on that list. It's to recognize that when your appetite changes significantly, the quality and variety of what you're eating become more important too.

Imagine you sit down to breakfast and what used to be two eggs, toast and fruit now feels like far too much.

You don't need to force yourself through the old breakfast simply because that's what you're used to eating. If you know you're probably going to be full after a small amount, think about what you'd most like your body to get from that smaller meal. Protein is a good place to start.

During significant weight loss, we don't only lose body fat. Some lean body mass can be lost too, which is why researchers and healthcare professionals have become increasingly interested in protecting muscle while people are using GLP-1 medications.

That might mean eggs at breakfast, Greek yogurt when a full lunch sounds like too much, cottage cheese and fruit, chicken or fish at dinner, beans or lentils, or a smoothie with a good source of protein when drinking something feels more appealing than chewing through a meal.

You don't need to chase an enormous protein number you saw someone recommend on TikTok. Protein needs aren't identical for everyone, and your healthcare provider or dietitian can help you figure out what's appropriate for you.

And there's another part of protecting muscle that we shouldn't forget: you have to use it. Strength or resistance exercise, adjusted for your abilities and health, is an important partner to adequate protein during weight loss. Current GLP-1 nutrition guidance emphasizes the two together rather than treating protein alone as the solution.

This sounds almost too simple to mention, but it can make meals much less overwhelming.

If your appetite has changed, your plate can change too.

GLP-1 medications affect hunger and fullness and can slow the movement of food through the stomach. For some people, a large meal that once felt perfectly normal can now leave them feeling uncomfortable.

Start with less. If you're still hungry, you can always have more. If you're not, you haven't spent the entire meal staring at a huge plate and feeling like you're supposed to finish it.

Smaller meals and snacks throughout the day may also be easier than trying to fit all of your nutrition into three large meals. Interestingly, current guidance notes that nausea can sometimes be worse after going long periods without eating, so skipping food all day because you're not hungry and then trying to eat dinner may not feel particularly good either.

A yogurt at ten o'clock, half a sandwich at lunch and something small again later may work better for you than forcing yourself through meals your appetite simply isn't interested in anymore.

There will probably be foods that sound wonderful one day and completely unappealing the next. That's okay.

Ideally, you still want variety. Fruits and vegetables provide vitamins, minerals, fibre and other beneficial compounds. Whole grains and legumes can contribute fibre and nutrients. Eggs, dairy foods, meat, fish, beans, nuts and seeds can provide protein along with a range of vitamins and minerals.

But this is real life, and nausea doesn't care that you planned salmon and broccoli for dinner.

If yogurt and berries sound manageable, eat yogurt and berries. If soup sounds better than a plate of meat and vegetables, have the soup. If a smoothie lets you combine fruit, yogurt and another protein source on a morning when breakfast sounds impossible, that's useful.

You don't have to force yourself through a giant salad because it's "healthy" when your stomach is telling you absolutely not.

Over the course of the week, keep looking for opportunities to bring variety back in. Think about what you can add to the foods you're already tolerating rather than constantly worrying about the foods you aren't eating perfectly.

When your appetite disappears, sometimes your usual eating and drinking cues seem to get quieter right along with it.

You may also be getting less fluid from food simply because you're eating less. If you're dealing with nausea, vomiting or diarrhea on top of that, hydration becomes even more important.

Keep water where you can see it. Sip throughout the day rather than waiting until you're thirsty and trying to drink a huge glass all at once. Soup, smoothies and foods with a high water content can contribute fluid too.

If you're vomiting repeatedly, having significant diarrhea, struggling to keep fluids down or noticing symptoms that make you concerned about dehydration, call your healthcare provider. That's not the time to simply tell yourself you'll try to drink more tomorrow.

If you've ever looked at another meal and thought, Nope. Not happening, you'll understand why smoothies, soups and other drinkable options can be so helpful.

They aren't a loophole or a lesser form of nutrition. Sometimes they're simply an easier way to get something into your body when your appetite isn't cooperating. Current GLP-1 nutrition guidance specifically recognizes smoothies, protein drinks, soups and other lower-volume options as practical choices when eating enough becomes difficult.

It's actually one of the reasons we've become so interested in the idea behind SmartSips at Nutramin.

Our current SmartSips were created for kids, but the idea behind them is wonderfully simple: a multivitamin doesn't necessarily have to be another pill or gummy you have to remember. It can be something you mix into the water you're already drinking.

And yes, we're working on an Adult Smart Sips formula too.

It's still in development, so we're not suggesting that adults use the children's version. But as we've learned more about the different ways people's nutritional routines can change throughout life, we've become even more excited about where a sippable adult multivitamin could fit.

A multivitamin can't take the place of protein, balanced meals or the personalized advice you may need while taking a GLP-1. But when appetite changes the way you eat, having another easy way to keep up with an everyday vitamin routine may be genuinely useful.

Constipation can become an issue for some people taking GLP-1 medications, which inevitably leads to the advice: eat more fibre.

That's reasonable advice, but there's a little more to it.

If you haven't been eating much fibre and suddenly decide tomorrow is the day you're going to consume as much as humanly possible, your digestive system may have some thoughts about that.

Foods such as oats, beans, lentils, berries, vegetables, fruit and whole grains can gradually bring more fibre into your meals. Fluids matter alongside fibre too, which brings us right back to keeping that water bottle nearby.

If you're already dealing with significant nausea, bloating, constipation or other digestive symptoms, talk with your healthcare provider about what you're experiencing. You don't have to assume that feeling miserable is simply the price of taking the medication. Sometimes symptoms, eating patterns or the way a dose is being tolerated need a closer look.

This may be the part of the GLP-1 conversation we most want people to hear. A smaller appetite isn't an invitation to stop nourishing yourself.

Your body still needs protein. Your bones still need nutrients. Your muscles still need to be used. Your digestive system still needs fibre and fluid. Your body still needs vitamins and minerals to do thousands of ordinary jobs every single day.

There will be days when you eat beautifully balanced meals and days when the best you can manage is a yogurt, half a sandwich and whatever sounded tolerable at dinner. You don't need to turn either day into a moral judgment about how well you're doing.

Pay attention to the pattern instead.

If you're consistently eating very little, struggling with nausea, having trouble getting enough protein or fluids, or wondering whether your smaller diet is covering your nutritional needs, bring that information to your healthcare provider. Those are useful things for them to know.

GLP-1 medications can change hunger in a way many people have never experienced before. Learning how to eat with that new appetite can take some figuring out.

You don't need to do it perfectly. You just want the food and drinks you can manage to give your body as much of what it needs as possible.
