This is summer on a plate. Watermelon, feta and mint is a wonderful combination — sweet, salty, cool and refreshing all at once — and it makes a light, hydrating GLP-1 lunch at around 240 calories. On a hot day, or when your appetite has gone and you want something that slips down easily, this is one of the most genuinely refreshing things you can eat.
A quick word first: I am not a doctor or a dietitian, just someone who lived this. None of these foods or supplements are medication, and if you are on a GLP-1, check anything new with your GP or pharmacist. Right, let us get to it.
For eating well on the jab, see my complete GLP-1 guide, and for staying hydrated, my thoughts on fibre on GLP-1 touch on it too.
Why this refreshing salad works
Sweet-and-salty is one of the great flavour combinations, and this delivers it with real benefits.
It is genuinely hydrating. Watermelon is over 90 percent water, so this salad helps with hydration — and staying hydrated on a GLP-1 is more important, and more often overlooked, than people realise.
Feta balances the sweetness. The salty, tangy feta against the sweet watermelon is what makes this special, and it adds a welcome protein hit.
Light, low-calorie and cooling. At 240 calories it is a genuinely light lunch, perfect for a hot day or when you want something that goes down easily.
The hydration point people miss on a GLP-1
Here is something that took me too long to work out. On a GLP-1, a lot of what people put down to the medication — the headaches, the tiredness, the fuzzy head — is actually mild dehydration. When you eat far less, you take in far less water from food, because a surprising amount of our daily fluid comes from what we eat. Add in that your thirst signals can be blunted along with your hunger, and it is genuinely easy to end up quietly dehydrated without noticing.
A salad built on watermelon, which is more than 90 percent water, is a small but real way to help. I am not pretending one salad solves hydration — drinking enough water is the main event — but water-rich foods genuinely contribute, and on a hot day this both cools you and tops up your fluids. If you get frequent headaches or afternoon slumps on the jab, look hard at your hydration before blaming the medication. It is one of the cheapest, easiest wins going, and refreshing foods like this are a pleasant part of the answer.
The macros that matter
Here is roughly what one serving gives you. Treat these as a guide rather than gospel, since it depends on your exact ingredients and portions:
| Approx per serving | Amount |
|---|---|
| Calories | ~240 kcal |
| Protein | 9g |
| Carbohydrate | 22g |
| Fat | 14g |
| Fibre | 4g |
The protein figure is the one I watch on a GLP-1. As a rough guide I aim for somewhere around 1.2 to 1.6g of protein per kilo of body weight across the day to protect muscle while losing fat, and I judge every meal by how much of that it contributes. I log meals like this in Cronometer (it is free) so I know I am actually hitting my targets rather than hoping. The first time I tracked properly I realised I was eating far less protein than I thought, so if you have never done it, give it two weeks.
What you need (serves 1)
- 2 thick slices of watermelon, cubed (about 200g)
- 40g feta, crumbled or cubed
- A big handful of fresh mint leaves, torn
- A handful of rocket (optional)
- 1 tsp olive oil
- Squeeze of lime
- Black pepper
- Optional: a scatter of pumpkin seeds for crunch and protein
How to make it
- Cube the watermelon and remove any seeds, then arrange in a bowl or on a plate.
- Scatter over the crumbled feta.
- Tear the fresh mint leaves over the top — be generous, the mint is essential here.
- Add the rocket if using, for a peppery edge.
- Drizzle with a little olive oil and a squeeze of lime, and season with black pepper.
- Scatter over pumpkin seeds for crunch if you like, and serve chilled.
- Best eaten cold on a hot day.
Making it more substantial
At 9g this is a light lunch, so on a hungrier day:
Add grilled halloumi or more feta. Halloumi and watermelon is a fantastic pairing and adds a proper protein hit.
Add grilled chicken or prawns. Either turns this into a more substantial, high-protein summer meal.
Add seeds or nuts. For crunch, healthy fats and a little more protein. See how much protein per day.
Why sweet and salty is such a winning combination
There is a reason sweet-and-salty combinations are so universally loved, from salted caramel to this watermelon and feta salad: the contrast makes each element taste more intense. The saltiness of the feta makes the watermelon taste sweeter and more vivid, while the sweet, watery melon tempers the sharp saltiness of the cheese. Add the cooling mint and a squeeze of lime for acidity, and you have got all the elements of a genuinely sophisticated dish from about four ingredients. It is a brilliant example of how contrast, rather than richness, can make food exciting. On a GLP-1, where you want maximum flavour and satisfaction from smaller portions, learning to use contrast like this — sweet against salty, cool against sharp — is a genuinely useful skill. It makes light, healthy food feel anything but boring.
Best fresh and chilled
This is at its best made fresh and served cold, so it is a make-and-eat salad rather than a big prep job. You can cube the watermelon ahead and keep it chilled, then assemble in a couple of minutes. If taking it out, keep it cold and add the dressing just before eating. A refreshing, quick option for my meal prep ideas for Mounjaro on hot days.
How it fits a full day of eating
This is a light, refreshing lunch rather than a high-protein one, so I lean on the rest of the day — a protein-solid breakfast from my high-protein breakfasts and a proper high-protein dinner — or add halloumi, chicken or prawns to the salad itself. On its own it is more of a cooling, hydrating light meal, and I am honest about that.
Add a protein and it becomes a complete summer meal. Otherwise high-protein snacks or a protein shake covers the gap. As always on a GLP-1, it is the day’s total protein that matters, not the single meal — and a hydrating, refreshing lunch has its own value on a hot day. My complete GLP-1 guide explains how I balance it.
No appetite today?
This is one of the best options for a no-appetite day — cool, sweet, hydrating and barely there, it slips down when nothing heavier will, and it helps with fluids at the same time. Even a small bowl is worthwhile. When you cannot face preparing anything, HelloFresh keeps ready meals coming. More in what to eat with no appetite.
Supplements that pair well
Since hydration is the theme, this pairs naturally with keeping your electrolytes up — Electrolytes are worth having on a hot day or if you get frequent headaches on the jab. A daily Super Supplemental covers general gaps when eating light. The free Lily & Loaf lifestyle analysis matches a routine to your goals.
Frequently asked questions
Does watermelon and feta really go together?
Wonderfully — the sweet, watery melon against the salty, tangy feta is a classic summer combination. The contrast makes both taste better. It is a genuine crowd-pleaser once people try it.
Is watermelon OK for weight loss?
Yes — it is low in calories, over 90 percent water and genuinely hydrating and refreshing. It satisfies a sweet craving for very little, which makes it a smart choice on a hot day.
How do I make it a proper meal?
Add grilled halloumi, chicken or prawns for a protein hit. Halloumi and watermelon in particular is a fantastic pairing that turns this into a substantial summer lunch.
Can watermelon really help with hydration?
It genuinely contributes, being over 90 percent water, though drinking enough water is still the main event. On a GLP-1, where mild dehydration is common, water-rich foods are a pleasant help.
Is the mint essential?
Yes, really — the fresh mint lifts the whole salad and ties the sweet and salty together. Do not skip it; it is what makes the dish rather than being a mere garnish.
The bottom line
Watermelon, feta and mint salad is summer on a plate — sweet, salty, cool and hydrating for around 240 calories, and one of the best things to eat when it is hot or your appetite has gone. On a GLP-1, where mild dehydration is common and often mistaken for medication side effects, a water-rich lunch is a genuinely useful, refreshing win. Add halloumi or chicken to make it a complete meal. To match your supplements to the summer and your goals, the free Lily & Loaf lifestyle analysis is a quick, no-pressure check.
The tools I lean on
If you are putting a GLP-1 routine together, this is the order I would do it in, free tools first:
- Track a fortnight of food in Cronometer so you can see your real protein and calories.
- Take the free Lily & Loaf lifestyle analysis to find the supplements actually worth buying.
- Start an Audible trial for something to listen to while you cook or walk.
- Keep HelloFresh on standby for the weeks cooking from scratch just is not happening.
