Gym-goers who want a cold fizzy drink
If you have been sweating, drink water for hydration first, as the NHS advises. You can then choose a can for its flavour, checking its sugar and caffeine content.
Who is choosing these drinks?
The useful distinction after a workout is between replacing fluid and choosing a fizzy drink for its taste alongside a snack.
Shoppers comparing sugar across multipacks
Look at the nutrition for one can and the exact variant name. Regular and zero-sugar drinks from the same brand can have different sugar figures, while some drinks with no added sugar still list naturally occurring sugars.
People avoiding caffeine after exercise
For an evening workout, or whenever you do not want caffeine, look for an explicitly caffeine-free variant. Do not assume that a zero-sugar cola or another flavour from the same brand is also caffeine-free.
What should you compare?
Decide what you want to drink after sweating, then compare individual cans before committing to a multipack.
| Priority | What to check | Your needs |
|---|---|---|
| Hydration | The NHS says water is the best way to replace fluid lost through physical activity. If you want carbonation without a sweet soft drink, consider sparkling water. | After sweating, I want a drink for hydration first. I can choose a flavoured can separately to have with my snack. |
| Sugar per can | Compare the stated serving size and sugars on the nutrition label. Pepsi UK lists 15g sugars in a 330ml regular Pepsi can and 0g in a 330ml Pepsi Max can; check the variant rather than relying on the brand name. | When I take a can from the fridge, I want to know its sugar figure—not just how many cans came in the pack. |
| Caffeine | Check the exact product name and ingredients for caffeine or an explicit caffeine-free statement. Pepsi UK lists caffeine in Pepsi Max; Your Coca-Cola UK describes Fanta Orange Zero as caffeine-free. | I may want fizz after an evening session without choosing a caffeinated variant by mistake. |
| Sweeteners and ingredients | Read the ingredients on the current can, including any phenylalanine statement that matters to you. Zero-sugar and no-added-sugar descriptions do not tell you every ingredient. | Before buying several cans, I want to check what is in this particular flavour and variant. |
| Pack and serving size | Check the number of cans, the volume of each can and whether the nutrition figures are given per 100ml or per can. Use the same basis when comparing two drinks. | I want a pack size that fits how I will use it, with a clear figure for the can I actually drink. |
Common buying mistakes
-
Treating a fizzy can as the hydration plan
A can chosen for flavour does not change the NHS advice that water is the best way to replace fluid lost through physical activity.
Drink water first or alongside your snack. If it is the fizz you want, sparkling water is another option.
-
Assuming every variant has the same sugar figure
Pepsi UK lists 15g sugars per 330ml regular Pepsi can, compared with 0g per 330ml Pepsi Max can. The brand name alone does not distinguish them.
Check the complete variant name and compare sugars for one can before choosing a multipack.
-
Reading “zero sugar” as “caffeine-free”
Pepsi UK lists caffeine in Pepsi Max, while Coca-Cola GB identifies Coca-Cola Zero Sugar Caffeine Free as a separate caffeine-free variant. Ingredients also differ between drinks.
If you want to avoid caffeine, look for an explicit caffeine-free statement and check the current can label.

Frequently asked questions
Should a fizzy drink be my main drink after the gym?
Choose water to replace fluid after sweating: the NHS says it is the best way to do so after physical activity. Have a fizzy soft drink for its taste alongside your snack if you want one, or try sparkling water if it is the carbonation you prefer.
How do I compare two can multipacks?
Check the exact variant, the number and size of cans, and nutrition for one can on a comparable basis. Pepsi UK, for example, lists 15g sugars in a 330ml regular Pepsi can and 0g in a 330ml Pepsi Max can; those figures describe different drinks, not a difference caused by pack size.
Which fizzy-drink variants are caffeine-free?
Look for an explicit caffeine-free statement on the particular variant. Coca-Cola GB describes Coca-Cola Zero Sugar Caffeine Free that way, and Your Coca-Cola UK does so for Fanta Orange Zero. Pepsi UK lists caffeine in Pepsi Max, so zero sugar alone is not a caffeine-free guarantee.
Is a zero-sugar fizzy drink the same choice as water?
No. A zero-sugar soft drink may contain sweeteners or caffeine, depending on the variant. For replacing fluid lost through sweating, the NHS recommends water; choose a flavoured can separately according to its label and the taste you want.
