GLP-1 Medications 101: What They Are and How They Work

So, youโve heard about GLP-1 medicationsโOzempic, Mounjaro, Zepbound, and the rest of the gangโand now youโre wondering what all the fuss is about. Do they actually work?
Are they some kind of magic weight loss potion? And most importantlyโwhat the hell can you eat while on them?
Buckle up, because weโre about to break it all down in a way that actually makes sense. No boring medical jargon, just real talk about what GLP-1s do, how they help with losing weight, and what you need to know before jumping in.
What Are GLP-1 Medications?
Letโs start with the basics: GLP-1 receptor agonists (catchy, right?) are a type of medication that was originally created to treat type 2 diabetes.
But, surprise surprise, they also happen to be brilliant at curbing appetite, regulating blood sugar, and helping people lose weight without feeling like theyโre constantly at war with their fridge.
Some of the most well-known GLP-1 medications include:
- Mounjaro โ Also known as Tirzepatide, a bit of a powerhouse when it comes to fat loss.
- Zepbound โ The new kid on the block, and letโs just say it means business.
- Ozempic/Wegovy โ The classics, famous for reducing appetite and stabilising blood sugar.
These bad boys work with your body to keep hunger levels in check, so you donโt feel like you need to eat your entire kitchen at 9 pm. Sounds dreamy, right?
How Do GLP-1s Actually Work?
Hereโs the science-y bitโbut donโt worry, Iโll keep it simple. GLP-1 medications mimic a natural hormone in your body called glucagon-like peptide-1 (hence the fancy name). This hormone does three big things:
- Slows down digestion โ You feel full for longer, which means no more wandering into the kitchen just because you’re bored.
- Tells your brain youโre satisfied โ Bye-bye mindless snacking!
- Regulates blood sugar โ Less sugar crashing, more steady energy.
The result? Weight loss that actually feels manageable.
And because youโre naturally eating less, itโs much easier to stick to an easy meal plan for the week, whether you’re following a vegetarian diet, looking for vegan recipes, or just trying to keep things balanced with a high-protein approach.

The Perks of GLP-1 Medications (a.k.a. Why Everyoneโs Talking About Them)
Alright, letโs get into the juicy benefits of being on one of these meds:
โ Effortless portion control โ No more battling your willpower at every meal.
โ Steady, sustainable weight loss โ This isnโt some crash diet nonsense.
โ Improved metabolism โ Your body gets better at handling food, instead of storing every bite as fat.
โ Better blood sugar control โ Whether you have diabetes or not, itโs a win-win.

Side Effects: The Not-So-Fun Part
Alright, I wonโt sugarcoat itโGLP-1s come with a bit of a learning curve. Some of the most common side effects include:
- Nausea โ Your stomach might need time to adjust, especially in the first few weeks.
- Digestive issues โ Think bloating, constipation, or (on the flip side) running for the loo.
- Fatigue โ Because your body is adjusting to eating less.
The good news? Most of these symptoms settle down over time, and there are ways to manage them. Check out my post ‘8 Foods to Avoid If Youโre Serious About Thriving on GLP-1 Medications‘ for tips on minimising side-effects!
Keeping your meals light but nutrient-dense can helpโthink GLP-1 breakfast ideas like scrambled eggs with avocado, Greek yoghurt with berries, or a high-protein smoothie.

Who Should (and Shouldnโt) Use GLP-1s?
Not everyone needs a GLP-1, and theyโre not a “get skinny quick” pill (because letโs be real, that doesnโt exist). These meds are best suited for:
- People who have struggled with weight loss for years and need extra support.
- Those with a high BMI or weight-related health issues like insulin resistance.
- Anyone looking for a long-term lifestyle change, not just a quick fix.
Who shouldnโt take them?
- People who just want to drop a few pounds for a holiday.
- Those with a history of certain thyroid conditions or pancreatitis.
- Anyone looking for a way to avoid healthy eating altogether (youโll still need to make smart food choices!).

What to Expect When You Start GLP-1s
If youโre thinking of trying Mounjaro, Wegovy or Zepbound, hereโs what the first few weeks might look like:
Week 1-2: Appetite starts to drop, but nausea might kick in. Stick to easy-to-digest foods (GLP-1 diet recipes with high protein and fibre help!).
Week 3-4: Cravings lessen, portions shrink naturally, and energy stabilises.
Month 2+: Weight loss starts to show, and side effects improve.
Itโs also a great time to build solid eating habits that focus on high-protein, fibre-rich meals.
