Calo vs Simmer Eats: Which Service Makes Healthy Eating Truly Effortless?
Eat Well, Effortlessly, and Without Compromise.
Healthy eating in the UK is having a bit of a moment, and honestly, it makes sense. People are paying more attention to what’s on their plate, but here’s the catch: wanting to eat better and having the time to make it happen are two very different things. In reality, life gets in the way. Between work, errands, and trying to have some kind of social life, cooking from scratch can feel like climbing a mountain after a long day.
That’s where healthy meal delivery services step in. They promise to take the pressure off while keeping your nutrition on track. But the gap is widening; convenience alone isn’t cutting it anymore. People want quick meals, yes, but they also want quality, freshness, and transparency.
Not all services are built the same. Let’s unpack two of the UK's leading meal prep services, Calo vs Simmer Eats and see which one actually makes eating well feel effortless, not like another task on your to-do list

What Makes Calo the Best Option for Effortless Healthy Eating?
Personalisation: Built for You, Not the Masses
This is where the gap really widens. One of Calo’s biggest advantages is that everything is fully personalised to your needs. It’s like choosing between a tailored suit and something straight off the rack, one just fits better, right? Let’s break it down simply:
Calo Meals
- Fully personalised calories and macros
- Built around your goals, preferences, and lifestyle
- Ability to adjust portions, swap meals, and exclude ingredients, all in seconds
Simmer Eats
- Fixed, pre-portioned meals

The takeaway:
Simmer Eats gives you a fixed plan. Calo gives you your plan.
It’s the difference between wearing something that “fits okay” and something tailored exactly to you. If you like things done your way, don’t compromise when it comes to your food. It’s simple, just let Calo do the work for you.

Variety: A Menu that Never Gets Old
Let’s be honest, nothing kills consistency faster than food boredom. And when it comes to eating well, sustainability only works if the menu keeps evolving and the food is actually worth it. The Calo kitchen offers you an ever-changing menu:
Calo Menu
- 100+ meals weekly
- 20+ daily options
- New dishes every 2 weeks
- Calo meal plans cover everything, including high-protein, vegan, halal, gut-friendly, and more
Simmer Eats
- 16 rotating dishes weekly
- Around 50 meals per month
The takeaway:
Simmer Eats gives you a decent rotation. Calo gives you a menu that moves with you. One feels like replaying your favourite songs on repeat, the other like discovering an endless playlist with new tracks every day. Both have their appeal, but the Calo menu speaks for itself.
Quality: Fresh Hits Different
Calo meals are like getting a freshly prepared dish from a high-end restaurant, just without leaving your house.
- Cooked daily
- Freshness you can taste
- 100% natural ingredients
- No processed fillers
- Chef-prepared
- Nutritionist-approved
Simmer Eats keeps things clean too, but meals are:
- Cooked in small weekly batches
- Stored for up to 5 days
- Built more for practicality than freshness
The takeaway:
If Simmer Eats is like a home-cooked meal prepped on Sunday, Calo meal prep feels like that same meal made fresh every single day. A noticeable upgrade in taste, texture, and overall experience.
Full Flexibility & Total Control: Nutrition on Your Terms
Calo gives you the flexibility to adjust timing, swap dishes, or pause orders anytime. Meals arrive fresh, exactly when and where you need them. Your nutrition keeps pace with your life, so you never really miss a meal.
Simmer Eats works on a weekly drop, once your order is placed, there’s little room to adjust. Meals arrive in bulk, stored in the fridge for up to 5 days. Miss a delivery? Your meals are left in a safe spot, but you don’t get the same on-demand convenience that Calo provides.
