Do not assume a ready-to-drink family pack fits a strict keto eating plan. Tesco Groceries lists 10g carbohydrate in each 200ml Yazoo No Added Sugar carton, while the reviewed litre bottles list 17.6g to 20.5g per 200ml across Tesco Groceries and Sainsbury’s. Choose a portioned pack only if its declared carbohydrate fits the planned allowance; making a shake from ingredients whose labels you can check offers more control over the recipe, but takes preparation.
Compare the amount you will actually drink with your planned allowance. Tesco Groceries lists 10g carbohydrate per 200ml Yazoo No Added Sugar carton; the reviewed litre bottles list 17.6g to 20.5g per 200ml across Tesco Groceries and Sainsbury’s.
The Yazoo No Added Sugar Chocolate multipack contains six 200ml cartons, so each person can take a defined portion. Tesco Groceries declares 10g carbohydrate per carton; the pack format does not, by itself, establish keto suitability.
A litre bottle can be poured for several people, but portions need measuring when carbohydrate intake matters. The reviewed Yazoo, Tesco and Sainsbury’s bottles contain five 200ml servings, according to their retailer listings.
Start with carbohydrate for the portion someone will drink, then decide whether individual cartons, a shared bottle or a homemade recipe suits the household.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate per portion | Compare the declared carbohydrate per carton or measured serving, not just per 100ml. Tesco Groceries lists 10g per 200ml Yazoo No Added Sugar carton; the reviewed litre bottles list 17.6g to 20.5g per 200ml across Tesco Groceries and Sainsbury’s. | I need to know whether the amount in my glass or carton fits the carbohydrate allowance I am using. |
| Label wording | Read the total carbohydrate line even when the front of the pack says ‘no added sugar’. Tesco Groceries lists 10g per 200ml for Yazoo No Added Sugar and 14g per 200ml for Mars No Added Sugar. | A no-added-sugar claim catches my eye, but I do not want to mistake it for a carbohydrate-free drink. |
| Pack and storage | Choose between fixed 200ml cartons and a bottle you will measure when pouring. For a bottle, follow its refrigeration and post-opening instructions; Tesco Groceries says to refrigerate its 1-litre chocolate flavoured milk and consume it within five days of opening. | Several people may want separate drinks, or we may prefer one shared bottle that we can finish within the time stated on its label. |
| Recipe control | If making a shake at home, check the carbohydrate declaration and intended quantity of each ingredient. Do not assume a homemade recipe meets a particular allowance. | Different people in the household may need different portions, and I can make the drink rather than buy it ready to serve. |
| Prescribed diets | For a medically prescribed ketogenic diet, use the individual guidance of the treating team rather than a retail label claim. The British Dietetic Association says medical ketogenic diet therapy should be managed by an experienced ketogenic diet team. | If a ketogenic diet has been prescribed, I need the treating team to assess the exact drink and portion. |
The wording does not describe total carbohydrate. Tesco Groceries lists 10g carbohydrate in a 200ml Yazoo No Added Sugar Chocolate carton.
Check the carbohydrate line for the portion you intend to drink, then compare it with your planned allowance.
The reviewed litre bottles contain five 200ml servings. Their declared carbohydrate per serving ranges from 17.6g to 20.5g across Tesco Groceries and Sainsbury’s listings.
Measure the amount poured rather than assuming each glass is one labelled serving.
A large bottle may not suit a household that drinks small portions infrequently. Tesco Groceries instructs shoppers to refrigerate its 1-litre chocolate flavoured milk after opening and consume it within five days.
Check the instructions on the bottle you buy and choose a pack size the household can use within its stated period.
An unfinished bottle may mean wasted drink.
A no-added-sugar claim does not show that a drink fits an individual medical prescription. The British Dietetic Association says medical ketogenic diet therapy should be managed by an experienced ketogenic diet team.
Ask the treating team to assess the current label and intended portion before including the drink.
These figures describe the named drinks and portions, not every product made by each brand.

Eight individual 330ml bottles provide defined portions for sharing. Check the current label’s carbohydrate amount per bottle before deciding whether one fits your planned allowance.
No. The claim does not mean the drink contains no carbohydrate. Tesco Groceries declares 10g carbohydrate per 200ml Yazoo No Added Sugar carton and 14g per 200ml portion of Mars No Added Sugar; compare the amount you would drink with your planned allowance.
Yazoo No Added Sugar Chocolate 6 x 200ml has the lowest declared figure among the reviewed family-format products, at 10g per carton according to Tesco Groceries. The reviewed litre bottles declare 17.6g to 20.5g per 200ml across Tesco Groceries and Sainsbury’s; the lower figure does not establish that a carton fits every keto plan.
Follow the instructions on the bottle you buy. Tesco Groceries says to refrigerate its 1-litre Chocolate Flavoured Milk after opening and consume it within five days; do not apply that period to a different drink without checking its label.
Do not assume a supermarket drink fits an individual prescription. The British Dietetic Association says medical ketogenic diet therapy should be managed by an experienced ketogenic diet team; ask the treating team to assess the exact product label and intended portion.
