Grocery shoppers comparing fat content
If you want a bar in a regular food order, compare the listed flavour’s total fat and saturates rather than assuming a high-protein or low-sugar description means less fat.
Who is this choice for?
Shoppers prioritising protein and sugar
If protein and sugars matter more to you than a reduced-fat claim, compare those figures alongside fat on the same bar’s nutrition panel. A product can meet one preference without meeting the other.
Shoppers checking allergens and substitutions
If an ingredient or allergen affects your choice, check the selected product and any substitute separately. Tesco advises customers with allergies, intolerances or specific dietary requirements to check labels and allergen information before buying or eating.
What should you check before ordering?
Start with the fat comparison that matches your goal, then check the exact flavour and pack you can order. A direct-from-brand product and a bar available in your grocery basket may suit different shopping plans.
| Priority | What to check | Your needs |
|---|---|---|
| Reduced fat | Look for a comparison with a similar bar, then read total fat per 100g. NHS guidance says reduced-fat wording means at least 30% less fat than a similar product; it does not mean the product is low in fat. | I want a stated reduction, not just a name that sounds lighter. Myprotein says Lean Layered Cookie Dough has 8.1g fat per 100g, 42% less than its cited typical-bar comparison; its White Chocolate and Raspberry flavour is stated as 8.6g and 38% less. |
| Fat and saturates | Compare both figures per 100g across the flavours you are considering. The NHS describes 3g fat or less per 100g as low in fat and more than 5g saturates per 100g as high in saturates. | A relative fat reduction may suit me even if the bar does not meet a low-fat threshold. I would check the saturates figure separately rather than treating total fat as the whole picture. |
| Protein and sugars | Read protein, sugars and fat on the same flavour’s panel; use per-bar figures to understand the stated serving. PhD lists 21g protein, 1.2g sugars and 9.2g fat per 64g Chocolate Brownie Smart Bar. | If protein and sugars lead my choice, I still want to know the fat content. PhD’s Chocolate Brownie figures describe that flavour and serving, not every Smart Bar. |
| Delivery and substitutions | Check the exact product in your basket and any substitution options. Tesco says personal-shopper notes can express a preference, but it cannot always meet them. | I want the bar with my grocery order, but a replacement flavour or brand might have different nutrition and ingredients. I would review the product actually delivered. |
| Ingredients and allergens | Read the selected pack’s ingredients, allergen declaration and precautionary statements; repeat the check for a substitute. Tesco advises checking this information before buying or eating where dietary requirements apply. | When an allergen matters to me, a category filter or brand-range description is not enough. I need the details for the exact bar I receive. |
What can catch you out?
-
Reading “high protein” or “low sugar” as “reduced fat”
Those descriptions refer to different nutrients. PhD lists 14g fat and 5.2g saturates per 100g for Smart Bar Chocolate Brownie, alongside its protein and sugars figures.
Compare total fat and saturates per 100g before deciding whether the bar fits a fat-focused choice.
-
Assuming reduced fat means low fat
A reduction is relative to a comparator. Myprotein states 8.1–8.6g fat per 100g for the two cited Lean Layered flavours, above the NHS low-fat guide of 3g per 100g.
Decide whether you want a reduction against a similar bar or a particular per-100g fat figure, and check the label accordingly.
-
Accepting a substitute without checking its label
A replacement bar may differ in nutrition or allergens. Tesco says shoppers can leave substitution preferences, but those preferences cannot always be met.
Set a preference where offered and check the exact delivered pack before eating it.
-
Missing a product’s consumption warning
PhD and Grenade product pages warn that excessive consumption may cause laxative effects. Quest says its protein bars contain sugar alcohols and that tolerance varies.
Read the warning on the individual product, particularly when choosing a multipack.
Relevant brands and shopping channels
A brand’s range description does not establish the nutrition or allergens of every flavour. Use these references to narrow your search, then check the individual product.
Myprotein
Its Lean Layered range offers a direct-from-brand option with a stated comparison against a typical protein bar.
- Myprotein states 42% less fat for Cookie Dough and 38% less for White Chocolate and Raspberry, using its cited typical-bar comparison.
- The stated 8.1g and 8.6g fat per 100g are both above the NHS low-fat guide of 3g per 100g. Check the flavour and delivery route before ordering.
PhD
Smart Bar is an option to examine when protein and sugars matter more to your choice than a reduced-fat comparison.
- The Chocolate Brownie panel lists 21g protein and 1.2g sugars per 64g bar.
- That same bar lists 9.2g fat per serving. PhD also warns that excessive consumption may cause laxative effects.
Grenade
Grenade’s UK OREO Protein Bar is presented by the brand as a high-protein, low-sugar option, rather than as a documented reduced-fat comparison.
- Grenade states 21g protein for the OREO Protein Bar.
- Check the exact bar’s fat panel and allergen declaration; Grenade’s OREO page also carries an excessive-consumption warning.
Barebells
Barebells has a flavour-led protein-bar range, and Tesco has listed a Soft Protein Bar in its online grocery category.
- Barebells states that products in its protein-bar range have no added sugar.
- Barebells directs shoppers to individual labels for allergens; products may contain lactose or traces of lactose, and bars may contain traces of gluten.
Quest
Quest is a protein-bar range to assess by individual pack if it appears among your UK shopping options.
- Quest states that its original protein bars contain up to 21g protein per bar.
- Quest says its bars use dairy-based proteins and contain sugar alcohols. Check the UK product label and retailer listing for the exact variant.
Tesco
Tesco is an online grocery channel for adding a listed protein bar to a wider food order, not a single bar formulation.
- Its online protein-bar category has included products from several brands, including Barebells.
- Tesco says substitution notes cannot always be accommodated and advises shoppers with dietary requirements to check product labels and allergens.

Questions about labels and delivery
Does “reduced fat” mean a protein bar is low in fat?
No. NHS guidance says reduced-fat wording describes at least 30% less fat than a similar product, while its low-fat guide is 3g fat or less per 100g. Read the per-100g figure as well as the comparison.
Should I compare bars per 100g or per bar?
Use per-100g figures to compare different bar sizes, then per-bar figures to understand the amount in the serving you are buying. Check that both sets of numbers refer to the same flavour.
Can a low-sugar protein bar still contain a substantial amount of fat?
Yes. PhD lists 1.2g sugars and 9.2g fat per 64g Chocolate Brownie Smart Bar. A sugars figure does not replace a check of total fat and saturates.
How can I manage substitutions in a Tesco grocery order?
Add a substitution preference where Tesco offers that option, then check any replacement you receive. Tesco says its personal shopper will try to follow notes but cannot always accommodate them.
Is a dietary filter enough to check a bar’s allergens?
No. Tesco advises shoppers with allergies, intolerances or specific dietary requirements to check the selected product’s label, ingredients and allergen information before buying or eating. Check a substituted bar separately.
