People packing one drink with lunch
An individual can is easier to allocate to one lunch than a large bottle. Standard Coca-Cola Zero Sugar and Pepsi Max are options when caffeine and sweeteners are acceptable.
Who is choosing cola for an office lunch?
People choosing a caffeine-free drink
Coca-Cola Zero Sugar Zero Caffeine and Pepsi Max No Caffeine are separate variants. Look for the explicit caffeine-free wording; a no-sugar name alone does not establish it.
People buying for several lunches
A multipack provides separate cans for different days. A large bottle may suit several servings where storage and the instructions for using it after opening work for you.
What should you check before choosing?
Choose the caffeine variant and serving format first, then read the sugars and ingredient declarations on the pack you plan to buy.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars per serving | Read the sugars figure and its serving basis. Coca-Cola Great Britain lists 0g sugars per 100ml for Coca-Cola Zero Sugar; Pepsi UK lists 0g per 330ml can for Pepsi Max. Check the exact variant rather than treating every diet or no-added-sugar label as the same declaration. | I want to know what the can I pack declares, not just what its name suggests. |
| Caffeine | Check the variant name and ingredients. Standard Coca-Cola Zero Sugar and Pepsi Max contain caffeine or caffeine flavouring; their explicitly labelled caffeine-free alternatives are distinct products. | If I avoid caffeine at lunch, a no-sugar claim on its own will not settle my choice. |
| Sweeteners | Read the current ingredients and any phenylalanine statement. The Coca-Cola and Pepsi variants described here use sweeteners; their no-sugar wording does not mean sweetener-free. | I need to check the particular sweeteners and warning on the pack, especially if I must avoid phenylalanine. |
| Pack format | Compare an individual 330ml can with the servings you would pour from a large bottle. Tesco lists its Diet Cola in a 2-litre bottle; check its storage and after-opening instructions if buying it for several lunches. | One can fits the lunch I am packing. For a bottle, I would need somewhere to store what remains. |
Common buying mistakes
-
Assuming no sugar also means no caffeine
Standard Coca-Cola Zero Sugar and Pepsi Max contain caffeine or caffeine flavouring; caffeine-free versions are sold under separate names.
If caffeine avoidance matters, choose a pack explicitly labelled Zero Caffeine, No Caffeine or Caffeine Free and check its ingredients.
-
Reading no sugar as no sweeteners
The Coca-Cola, Pepsi and Tesco products discussed here use sweeteners. The described Coca-Cola and Pepsi variants also carry a phenylalanine statement.
Read the current ingredient list and warning if you need to avoid a particular sweetener or phenylalanine.
-
Choosing a large bottle for just one lunch
Tesco Diet Cola comes in a 2-litre bottle, so one packed-lunch serving leaves an opened bottle to store.
Choose an individual can if you only need one drink; consider a bottle when you have a plan for its remaining servings and can follow its storage instructions.

Questions about no-sugar cola
Does no sugar mean a cola is caffeine-free?
No. Standard Coca-Cola Zero Sugar and Pepsi Max contain caffeine or caffeine flavouring. If you need to avoid caffeine, select a variant explicitly labelled caffeine-free and check the pack.
Can a no-sugar cola still contain sweeteners?
Yes. The Coca-Cola, Pepsi and Tesco products discussed here use sweeteners. Read the current ingredients and any phenylalanine warning if either affects what you can choose.
Should I pack a 2-litre bottle for one lunch?
An individual 330ml can is simpler to allocate to one lunch. A 2-litre bottle such as Tesco Diet Cola makes more sense when you plan to use several servings and can store it as the label instructs after opening.
What should I check on the pack before buying?
Check the exact variant, sugars figure and serving size, followed by the caffeine and sweetener information. If a phenylalanine warning matters to you, read that statement on the physical pack too.
