Weekly shoppers comparing total fat
If you are buying several meals for the freezer, comparing fat per 100g helps you judge similar products without confusing a smaller portion with a lower-fat recipe.
Who these checks are for
Shoppers planning portions
If you choose single-serve meals for convenience, check the nutrition for the amount you will eat as well as the per-100g figures. Calorie-controlled branding does not answer every question about fat or salt.
Shoppers comparing protein and saturated fat
If protein is part of your comparison, read total fat and saturated fat separately. A meal’s protein positioning does not settle either measure or its suitability for someone avoiding an allergen.
What to check when choosing
Start with comparable per-100g figures, then check the portion, ingredients and preparation details of each meal you might add to the freezer.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Compare total fat per 100g across similar meals. NHS food-label guidance describes 3g of fat or less per 100g as low fat for foods; check the actual figure rather than a range name. | I want to compare recipes without letting different pack sizes obscure the total-fat figure. |
| Saturated fat | Read saturates separately from total fat, both per 100g and for the portion you plan to eat. A low-saturated-fat description does not establish low total fat. | Lower saturated fat matters to me, but I also want to know the meal’s total fat. |
| Portion and salt | Check pack weight and stated servings, then compare calories, fat and salt for the amount you expect to eat. | If I am eating the whole pack, I want figures that reflect the whole meal rather than a smaller stated serving. |
| Ingredients and allergens | Read the current pack’s ingredients and allergen advice, including when buying a familiar meal again. Iceland advises shoppers that product information can change. | Someone in my household needs me to check the specific pack before I buy or prepare it. |
| Storage and cooking | Check the pack’s freezer-storage directions and the cooking method and standing time for that particular meal. | I am stocking up for the week and need to store and prepare each meal as directed. |
Common mistakes to avoid
-
Assuming a calorie-controlled range is low in fat
Tesco’s frozen Under 500cal category and M&S Count On Us branding identify calorie-focused options, not the total-fat value of every meal.
Check total fat per 100g on the exact product before adding it to your basket.
-
Comparing only the calorie or serving figure
Different pack and serving sizes can make front-of-pack figures difficult to compare directly.
Compare similar meals per 100g first, then read calories, fat, saturates and salt for the amount you intend to eat.
-
Treating low saturated fat as low total fat
Waitrose lists Birds Eye Get Real Protein Thai Red Chicken Curry at 3.4g total fat per 100g, although its listing describes it as low in saturated fat. That total-fat figure is above the NHS low-fat guide of 3g or less per 100g.
If total fat is your priority, check its figure separately from saturates.
-
Relying on an old online ingredients list
Ingredients and allergen information can change, which matters when someone in the household must avoid an ingredient.
Read the current physical pack’s ingredients and allergen advice before preparation.
Retailer and brand references
These ranges can help you find meals to compare, but their category names do not replace the nutrition and storage information on an individual product.
Tesco
Tesco Groceries has a frozen Under 500cal Meals category that includes Tesco Calorie Controlled meals.
- A calorie-based category offers a starting point for browsing frozen meals.
- Check each product’s total fat per 100g; the category name does not establish that it is low fat.
M&S
M&S has a frozen ready-meal range and separately describes its Count On Us dishes as calorie controlled.
- The two ranges provide ways to browse ready meals and calorie-controlled dishes.
- Confirm that a particular Count On Us dish is frozen and check its own total-fat figure.
Waitrose
Waitrose lists own-label and branded frozen ready meals, including products with individual nutrition panels.
- An individual panel lets you compare total fat and saturates as separate values.
- Check the current listing and pack for the particular meal you plan to buy.
Iceland
Iceland lists Slimming World frozen meals and describes its MyProtein range as offering high-protein, low-fat meals.
- Its frozen-meal ranges offer products to assess using individual labels.
- A range-level description does not establish the nutrition or allergens of every meal; read the current pack.

For a weekly freezer shop, compare this 350g meal with similar frozen ready meals using the current pack’s per-100g nutrition and the values for the amount you intend to eat. The product information flags milk and barley and says bones may remain; check the pack’s allergen advice and follow its cooking directions.
Questions about frozen ready meals
Does “calorie controlled” mean a frozen meal is low in fat?
No. Calorie positioning does not establish a meal’s total-fat value. Compare total fat per 100g on the specific product: NHS food-label guidance describes 3g or less per 100g as low fat for foods. Then check the values for the portion you will eat.
How do I compare frozen meals in different pack sizes?
Use the per-100g nutrition figures to compare similar meals, then read the per-serving or whole-pack figures for the amount you expect to eat. Check how many servings the manufacturer assigns to each pack.
Can a meal be low in saturated fat but not low in total fat?
Yes. Waitrose describes Birds Eye Get Real Protein Thai Red Chicken Curry as low in saturated fat, while listing 3.4g total fat per 100g. That exceeds the NHS low-fat guide of 3g total fat or less per 100g, so check both figures when total fat matters to your choice.
What should I check when buying for someone with a food allergy?
Read the ingredients and allergen advice on the current physical pack each time. Iceland advises that website product information can change, so an earlier online listing should not replace the label of the meal you are preparing.
How should I store and cook frozen ready meals?
Follow the storage, cooking and standing-time instructions on each meal’s pack. Methods differ between products, so use the directions for that meal and the appliance you are using.
