Solo shoppers comparing total fat
If you usually eat the whole ready-meal pack, compare fat per 100g between similar meals and check the figure for the full pack. The NHS food-label guidance defines low fat as 3g of total fat or less per 100g.
Who is this choice for?
Shoppers considering calorie-controlled meals
A frozen meal with a stated calorie limit can help narrow your choices, but it does not establish that the meal is low in fat. Tesco lists 350g Calorie Controlled meals in its frozen under-500-calorie category; compare their current labels before choosing one for a reduced-fat purchase.
People with limited freezer space
Individual packs make it easier to plan how many meals to store. Check the space available before buying several, and choose a pack size you expect to eat rather than assuming every meal-for-one portion suits you.
What should you check?
Start with comparable nutrition figures, then check whether the whole pack, storage needs and cooking directions fit the meal you are planning.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Compare similar meals per 100g; NHS guidance defines low fat as 3g or less per 100g. Check the full-pack figure and number of stated servings as well. | I expect to eat the whole pack, so its total matters alongside the per-100g comparison. |
| Other label figures | Read saturated fat and salt per 100g and for the amount you will eat. NHS guidance classifies more than 5g of saturated fat or 1.5g of salt per 100g as high. | A lower total-fat figure is not my only consideration; I want to compare saturates and salt between meals too. |
| Portion and storage | Check pack weight, stated servings, the number of packs you plan to buy and the freezer space they require. | Will these meals fit in my freezer, and is each pack an amount I plan to eat at one sitting? |
| Preparation and ingredients | Check the current pack for allergens, ingredients, storage directions and cooking instructions for your appliance, including any stated wattage or standing time. | I need a meal I can prepare using my appliance, with ingredients and allergen information I can check before eating. |
Common buying mistakes
-
Assuming calorie-controlled means low fat
A calorie figure and a total-fat figure answer different questions. Tesco’s frozen under-500-calorie listing identifies meals to compare, but does not establish that each one is low in fat.
Use the category to make a shortlist, then compare total fat per 100g and for the pack on each current label.
-
Looking at total fat alone
In its 2025 assessment of 1,511 chilled and frozen ready meals from 11 major UK retailers, Action on Salt & Sugar classified 56% as high in salt and 42% as high in saturated fat. A total-fat comparison does not replace those separate label checks.
Compare saturated fat and salt on the same per-100g basis, then check the figures for the amount you will eat.
-
Treating pack weight as a nutrition claim
A 350g or 400g meal may be intended as a convenient individual pack, but its weight alone says nothing about its fat or salt content.
Check the stated servings and nutrition for the full pack if that is the amount you plan to eat.
-
Stocking up without checking the pack
Freezer capacity limits how many individual meals you can store. Ingredients, allergen details and preparation directions also need checking on the product you receive; Iceland advises that its published product information can change.
Check storage space before buying several packs, and follow each meal’s current cooking and defrosting instructions.
Retailer and brand references
These ranges offer different starting points for comparing frozen meals; their range names do not establish the fat content of every product.
Iceland / Slimming World
A product-level low-fat statement is available for Slimming World Free Food Lunch Bowls Pasta Bolognese 400g, according to Iceland’s listing.
- The listing identifies this specific 400g frozen meal as “Low Fat”.
- Check its current pack for nutrition, allergens and preparation directions; the retailer advises that published product information can change.
Tesco
Tesco’s frozen under-500-calorie category lists 350g Calorie Controlled Chicken Tikka Masala and Lasagne as meals to compare.
- The category gives calorie-led shoppers identifiable frozen options.
- A place in that category does not establish low-fat status; compare each product’s current nutrition label.
M&S
M&S describes Count On Us as calorie controlled and lists frozen ready meals separately, including products in 270g and 400g packs.
- The two ranges provide different places to look for portioned dishes and frozen meals.
- Count On Us is not a frozen-only range, and these range listings do not establish that a particular frozen meal is low in fat.
Waitrose
Waitrose lists several 400g frozen ready meals, including Beef Lasagne, Cottage Pie and Vegetable Lasagne.
- The listed meals offer different recipes in the same 400g pack size for label comparison.
- The range listing does not establish a lower-fat claim for those individual meals.

Myprotein Chicken Tikka 350g
The 350g frozen meal is described by Joybuy as suitable for microwave cooking from frozen. For a reduced-fat comparison, check the current pack’s total fat per 100g and per pack, alongside saturated fat, salt, allergens and the exact cooking directions.
Questions about frozen meals for one
Which fat figure should I compare?
Compare total fat per 100g across similar meals, then check the figure for the full pack if you will eat it all. NHS food-label guidance defines low fat as 3g of total fat or less per 100g; check the pack’s stated number of servings rather than assuming it contains one.
Does “under 500 calories” mean low fat?
No. A calorie limit does not tell you whether a frozen meal meets the NHS low-fat label threshold. Check its total fat per 100g, along with saturated fat and salt, before comparing it with another meal.
What should I check besides total fat?
Compare saturated fat and salt per 100g and for the amount you will eat. NHS guidance classifies more than 5g of saturated fat or 1.5g of salt per 100g as high, so a lower total-fat figure does not settle those separate comparisons.
Can I use an online listing to check allergens?
Use the listing to shortlist meals, but read the actual pack before cooking or eating. Iceland advises that ingredients, nutritional content and allergy information published online can change.
Can I defrost a frozen meal and refreeze it?
Follow the instructions for the specific meal rather than applying one rule to every product. Iceland’s listing for Slimming World Free Food Lunch Bowls Pasta Bolognese 400g says to use it within 24 hours once defrosted and not to refreeze it; check your chosen pack for its own directions.
