Strict low-fat label checkers
If a low-fat designation matters to you, start with total fat per 100g. NHS guidance describes 3g or less per 100g as low for food; check saturated fat and salt separately.
Who needs which checks?
Single-serving convenience shoppers
If you want one frozen meal for a quick dinner, check the serving size and whole-pack nutrition. Calories, protein and vegetable content answer different questions from total fat.
Shoppers comparing meal sizes
Compare pack weights and stated servings alongside nutrition. A pack intended for two and a single-serving meal do not represent the same amount of food.
What should you compare?
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Compare total fat on the same per-100g basis. NHS guidance describes 3g or less per 100g as low for food; also read the serving or whole-pack figure. | I need a meal that meets a low-fat criterion, rather than one identified only by its calorie count or range name. |
| Other nutrition | Read saturated fat and salt per 100g, then check the figures for the amount you expect to eat. Check fibre where it is declared. | Lower total fat is only part of my decision; I also want to see what a full meal contributes. |
| Pack size | Check pack weight, stated servings and whether the nutrition figures refer to one serving or the entire pack. | A meal for one suits me differently from a pack designed for two, even if their per-100g figures look similar. |
Common selection mistakes
-
Reading calorie or protein claims as low-fat claims
These describe different measures. For example, Waitrose & Partners lists 3.4g total fat per 100g for Birds Eye Get Real Protein Thai Red Chicken Curry, despite its protein-focused presentation.
If a low-fat designation is your requirement, check total fat per 100g before using other claims to distinguish meals.
-
Stopping at the total-fat figure
Total fat alone does not describe a meal’s saturated fat or salt. The amount eaten also matters when a pack contains more than one stated serving.
Compare these label figures on the same basis, then check the serving or whole-pack values for the amount you plan to eat.
-
Relying only on an online ingredient listing
Iceland notes that ingredients, nutrition and allergen information can change, so a product page may differ from the pack in hand.
Check the actual packaging for ingredients, allergens, nutrition, storage and cooking instructions, particularly if you must avoid an allergen.
Relevant brand and retailer references
Tesco
Tesco Groceries lists frozen ready meals, including 400g Hearty Food Co meals, and offers an under-500-calorie navigation category.
- The listing gives shoppers identifiable frozen meal formats to compare.
- Neither the category nor a calorie description establishes a meal’s total fat per 100g.
Waitrose
Waitrose & Partners publishes per-100g nutrition and serving information for named frozen meals.
- Its frozen Chicken Tikka Masala & Rice lists 3.4g fat per 100g, while its frozen Pea & Asparagus Risotto lists 3.5g per 100g.
- Both listed total-fat figures exceed the NHS’s 3g-per-100g low-fat guide for food; check each product rather than assuming a frozen range qualifies.
Iceland
Iceland says its Slimming World range includes ready meals.
- The range provides named meals whose individual labels can be checked.
- A range name does not establish total fat for every meal. Iceland advises checking the actual pack because product information can change.
Birds Eye
Waitrose & Partners lists Birds Eye Get Real Protein Thai Red Chicken Curry as a 350g frozen meal.
- The listing gives per-bowl protein and per-100g fat figures for comparing distinct label measures.
- It lists 3.4g total fat per 100g, above the NHS’s 3g-per-100g low-fat guide for food.
Asda
Asda lists Weight Watchers from Heinz Chicken Tikka Masala as a frozen ready meal.
- Check the individual meal’s nutrition label: its brand and category do not establish its total fat per 100g.

Questions about choosing frozen meals
What does “low fat” mean on a frozen meal label?
NHS food-label guidance describes 3g total fat or less per 100g as low for food. Read the total-fat value, not just a calorie statement or the name of a meal range.
Does “low in saturated fat” also mean low in total fat?
No. They are separate nutrition values. Waitrose & Partners lists 3.4g total fat per 100g for Birds Eye Get Real Protein Thai Red Chicken Curry, which exceeds the NHS’s 3g-per-100g low-fat guide for food.
Should I compare figures per 100g or per pack?
Use per-100g figures to compare meals on the same basis, then check serving or whole-pack figures for the amount you intend to eat. A pack may contain more than one stated serving.
How should I prepare a frozen ready meal?
Follow the cooking and storage instructions on the actual pack for the product and appliance you are using. Do not substitute instructions from a different meal.
Can I rely on an online allergen listing?
Check the actual packaging before eating. Iceland warns that ingredients, nutrition and allergen information can change, so an online listing should not replace the label on the pack.
