Best Low Calorie Ready Meals UK: Supermarket Ranges Compared
Low calorie ready meals can be useful when a busy week would otherwise turn into takeaway or random snacking. The trick is choosing meals that are filling enough to count as dinner, not just low enough to look good on the front of the pack. This guide compares the ranges each UK supermarket actually sells, with the protein, calories and prices they publish, and shows when a simple homemade swap is better.
For a full week instead of one-off meals, compare the printable 1500 calorie meal plan and the main low calorie foods UK guide.
For named meals at one supermarket, see the Sainsbury's healthy ready meals guide, the Lidl high-protein ready meals and Aldi's protein pots and breads.
Quick Answer: What Makes a Ready Meal Worth Buying?
A good low calorie ready meal should have enough protein, fibre or vegetables to feel like a meal. A 280 calorie pasta pot with little protein can leave you hungry; a 450 calorie curry with lean protein, rice and vegetables may work better inside a 1500 or 1800 calorie day.
Use the front-of-pack calories as a starting point, then check protein, portion size, vegetables and whether you need to add a side salad, soup or yogurt to make it complete.
| What to check | Good target | Why it matters |
|---|---|---|
| Calories | 350-550 kcal for lunch or dinner | Low enough for a calorie-controlled day but not too small |
| Protein | 20g+ if possible | Helps the meal feel more satisfying |
| Vegetables | Visible veg or add a side | Adds volume, fibre and micronutrients |
| Salt | Compare labels | Ready meals can vary a lot by range and sauce |
| Side plan | Salad, veg, fruit, soup or skyr | Turns a small ready meal into a workable meal |
Best Ready-Meal Styles for Calorie Control
These meal types tend to work better than ultra-creamy or pastry-heavy options because they are easier to balance with protein and vegetables.
| Ready-meal style | Best supermarket examples to look for | Easy upgrade |
|---|---|---|
| Chilli and rice | Beef, turkey, bean or lentil chilli bowls | Add salad or extra frozen veg |
| Curry and rice | Chicken tikka, lentil dal, Thai-style curry | Choose leaner sauces and add spinach |
| Stir fry or noodle bowls | Chicken, prawn, tofu or vegetable noodle meals | Add edamame or cooked chicken |
| Soup plus protein side | Chicken, lentil, bean or vegetable soup | Add skyr, eggs, tuna or cottage cheese toast |
| Fish or chicken with potatoes | Balanced chilled meals with veg included | Add microwave veg if the portion is small |
The Ranges Worth Knowing, Supermarket by Supermarket
Each of the big UK supermarkets now has at least one ready meal line built around calories or protein. The table shows what each range is built to, using the figures the supermarket published. We checked them on 24 September 2026; ranges, recipes and prices change after launch and vary by store, so the pack in front of you is the number to trust.
| Supermarket | Range | What it is built to | Pack and price |
|---|---|---|---|
| Tesco | Calorie Controlled | Lower-calorie chilled meals, e.g. Chicken Roast Dinner (252 kcal) and Chicken in Mushroom Sauce (269 kcal) | 370-380g; price varies |
| Sainsbury's | High Protein | At least 31g protein for under 500 kcal | 400g, £3.75 at launch |
| Sainsbury's | Small but Mighty | Under 350 kcal, at least 20g protein, a source of fibre | 300g, £3.00 at launch |
| Sainsbury's | Be Good To Yourself | The calorie-led healthier-choice line | Varies by meal |
| Asda | Protein power pots | High in protein, with at least 80g of fruit or veg per pot | 250g, £2.50 at launch |
| Aldi | Inspired Cuisine Protein Pots | At least 30g protein per serving; frozen | 350g, £1.75 |
| Lidl | Chef Select High Protein | Protein-led chilled meals; nutrition is on the pack, not online | 380g; price in store |
Which One to Pick
For the most protein per calorie, start with Sainsbury's High Protein meals or Aldi's protein pots. Worked out from Aldi's own per-100g figures, the Teriyaki Noodles pot comes to about 35g of protein for about 340 kcal, and at £1.75 it is also the cheapest pot in the table.
For the fewest calories, Tesco's Calorie Controlled meals are the lowest we could confirm, at around 250-270 kcal for the two above. That is small for a main meal, so check the protein and plan a side: salad, microwave veg, soup or a pot of skyr.
For vegetables, Asda's power pots are the only range here built to a fruit-and-veg minimum - at least 80g per 250g pot, which is one of your five a day.
Tesco has also announced six new high-protein ready meals. We could not read their details from Tesco directly, so they are not in the table yet. The individual Sainsbury's meals, with protein and calories for each, are in the Sainsbury's guide linked below.
When Homemade Is Better Than Ready-Made
If you are buying the same ready meal every week, it is worth making a two-portion batch version. Turkey chilli, chicken curry, lentil dal, tuna pasta bake, tofu stir fry and jacket potatoes are all cheap UK supermarket meals that reheat well and give more control over portions.
Ready meals are best used as a backup, a lunch option or a low-effort dinner inside a planned week, not as the entire diet. Pair them with the printable meal plan hub if you want structure without cooking from scratch every night.
