Shoppers with a 500 kcal meal limit
You want a convenient meal from the freezer and need to check the prepared serving, rather than mistake a per-100 g figure for the whole meal.
Who is this for?
Shoppers comparing protein
You want to compare protein in grams without overlooking the meal’s calories, salt or cooking and storage instructions.
Shoppers checking allergens or individual dietary advice
You need to read the ingredients and product warnings, particularly if an allergy or advice about protein or potassium affects your choices.
What should you check?
Check the prepared portion against the calorie limit before comparing protein; then confirm that the meal’s other label details fit your needs.
| Priority | What to check | Your needs |
|---|---|---|
| Whole-meal energy | Find the kcal for the prepared pack or stated serving. Check the number of servings; do not use a per-100 g figure as the whole-meal figure. | I want the portion I actually eat to stay under 500 kcal. |
| Protein per serving | Compare protein in grams for the whole prepared serving, using the same portion basis as the calorie figure. Do not rely on the range name alone. | Once the meal meets my calorie limit, I want to compare how much protein each serving contains. |
| Salt and ingredients | Read salt per pack, the ingredient list, highlighted allergens and any product-specific warnings on the current label. | Calories and protein are not my only checks, especially when an allergen or individual dietary advice matters. |
| Frozen format | Confirm the storage and cooking instructions for the exact meal. A high-protein ready meal may instead require refrigeration. | I need a meal I can keep in the freezer and prepare using its stated instructions. |
Common buying mistakes
-
Using the per-100 g calories as the meal total
Tesco lists 102 kcal per 100 g but 366 kcal per microwaved pack for its High Protein Tandoori Chicken Masala. Those figures answer different portion questions.
Use the energy figure for the whole prepared pack or the serving you intend to eat, and check the serving count.
-
Assuming a high-protein meal is frozen
Waitrose’s High Protein Moroccan Style Chicken Tagine is listed at 393 kcal per pack, but its storage instruction is to keep it refrigerated.
Check storage, whole-serving calories and protein on the exact product before treating it as a frozen option.
-
Stopping at the calorie and protein figures
Tesco’s Tandoori Chicken Masala lists 1.25 g salt per microwaved pack. Iceland’s Myprotein Katsu Chicken with Rice lists several allergens and warns that it is not suitable for a low-potassium diet.
Compare salt per meal and read the current pack’s ingredients, allergens and warnings.
-
Applying a general high-protein goal to an individual medical diet
Royal Devon University Healthcare NHS Foundation Trust advises that people with kidney disease who are not receiving dialysis may need to avoid eating too much protein.
If you have been given individual advice about protein or potassium, follow your renal team’s or dietitian’s guidance when choosing meals.
Retailer ranges to compare
Range names can narrow a search, but the individual product determines whether a meal is frozen, under 500 kcal and suitable for your protein comparison.
Tesco
Tesco has a frozen Under 500cal Meals category as well as high-protein ready meals.
- Tesco lists its High Protein Tandoori Chicken Masala at 366 kcal and 21.1 g protein per microwaved pack.
- Check the current label for each meal: a category name does not establish its protein, salt or serving details.
Iceland
Iceland describes its Myprotein ready-meal range as meals cooked straight from the freezer.
- The frozen format makes the range relevant when freezer storage is essential.
- Check each meal’s calories and label warnings. Iceland’s Myprotein Katsu Chicken with Rice carries allergen information and a low-potassium warning.
M&S
M&S lists frozen ready meals, High Protein products and its calorie-controlled Count On Us range separately.
- These ranges offer different starting points for checking format, calories and protein.
- A calorie-controlled or High Protein range name does not establish that an individual meal is frozen and under 500 kcal.
Waitrose
Waitrose’s high-protein ready meals provide a useful reminder to check storage as well as nutrition.
- Waitrose lists its High Protein Moroccan Style Chicken Tagine at 393 kcal and 33 g protein per pack.
- That tagine must be kept refrigerated, so it is not a frozen-meal option.

Frequently asked questions
Does “high protein” mean a frozen meal is under 500 kcal?
No. Check calories for the whole prepared pack or serving, then compare protein in grams on the same basis. Tesco lists its frozen High Protein Tandoori Chicken Masala at 366 kcal and 21.1 g protein per microwaved pack, but those figures apply to that product.
Does a chilled high-protein meal meet a frozen-meal requirement?
No. Waitrose lists its High Protein Moroccan Style Chicken Tagine at 393 kcal and 33 g protein per pack, but instructs shoppers to keep it refrigerated. Check storage instructions even when the nutrition figures fit your criteria.
Which allergen details should I read?
Read the current pack’s ingredients and highlighted allergens before choosing. UK food-labelling guidance from the Department for Environment, Food & Rural Affairs and the Food Standards Agency covers ingredients including allergens; Iceland’s Myprotein Katsu Chicken with Rice, for example, lists wheat, soya, barley, mustard, celery and milk.
What if I have been given advice about protein or potassium?
Use your individual clinical or dietitian advice rather than assuming a high-protein meal is suitable. Royal Devon University Healthcare NHS Foundation Trust advises that people with kidney disease who are not receiving dialysis may need to avoid too much protein; also check each meal for product-specific warnings.
