Who is choosing?

Training with a high-cocoa preference

If a clearly stated cocoa percentage matters to you, treat the bar as an optional snack rather than assuming that more cocoa makes it a better carbohydrate choice before exercise.

Eating shortly before a workout

If you need a snack before training, compare carbohydrate and fat per 100g and choose something you already tolerate. Sports Dietitians Australia advises familiar foods that are high in carbohydrate and low in fat before exercise.

Buying food for a school setting in England

Check the school-food requirements that apply to the setting. England’s school-food framework and its retail rules on promotions of certain products are separate matters; neither should be treated as a single UK-wide school-meal rule.

What should you check?

Decide whether the snack is mainly for carbohydrate before training or for the taste of high-cocoa chocolate. Then check the exact pack for its nutrition, ingredients and portion information.

PriorityWhat to checkYour needs
Pre-workout snack Compare carbohydrate and fat per 100g, then consider your portion and time before exercise. Sports Dietitians Australia advises familiar, well-tolerated, high-carbohydrate, low-fat foods. I’m eating soon before training and want a familiar snack that agrees with me. I won’t assume a dark bar is the right carbohydrate choice.
Cocoa content Read the declared cocoa-solids percentage, not just the word “dark”. Lindt Excellence and Divine state 70%; Tesco’s listing for Cadbury Bournville Classic states 36% minimum. I want a stated high-cocoa bar, even if that is a different priority from getting carbohydrate before a workout.
Ingredients and allergens Read the current ingredients and allergen statement for the exact variant, including any “may contain” warning. Do not use cocoa percentage to judge dietary suitability. For me, the precise pack and its ingredient statement matter more than whether the wrapper says “dark”.
Individual exercise plan If you use insulin or other glucose-lowering medication, follow your agreed exercise plan rather than choosing a bar by cocoa percentage. North Cumbria Integrated Care describes exercise-related carbohydrate and medication decisions in an individual care context. I need to use the carbohydrate source and plan agreed with my diabetes healthcare team, not treat chocolate as a substitute.

Common buying mistakes

  • Assuming more cocoa means better pre-workout fuel

    Montezuma’s lists 18g carbohydrate and 53g fat per 100g for Absolute Black 100% Cocoa. Sports Dietitians Australia’s pre-exercise guidance instead favours foods high in carbohydrate and low in fat.

    Choose a higher cocoa percentage for that preference, not as a shortcut for choosing a carbohydrate snack. Compare both nutrients on the current pack if you plan to eat before training.

  • Assuming every dark bar fits the same dietary requirements

    “Dark” describes the chocolate, not the full ingredient or allergen declaration. Suitability can differ between products and variants.

    Check the exact pack’s ingredients, allergen statement and “may contain” warnings rather than relying on the cocoa percentage or wrapper.

  • Confusing school-food rules with retail-promotion rules

    England’s Requirements for School Food Regulations 2014 define confectionery to include chocolate. Department of Health and Social Care guidance on certain retail promotions also applies to England, but addresses a different setting.

    For school provision, check the applicable school-food framework and UK nation. Assess any retail-promotion question separately under the current rules for the product and retailer.

  • Using chocolate instead of an individual diabetes exercise plan

    Exercise-related carbohydrate and medication decisions depend on individual circumstances. North Cumbria Integrated Care’s guidance discusses them in the context of a plan agreed with a diabetes healthcare professional.

    If you use insulin or glucose-lowering medication, follow your own team’s advice on exercise and the carbohydrate source to carry.

Brand references for dark chocolate

These figures describe the named bars, not every product made by each brand. The nutrition values below are per 100g so that bars with different pack sizes can be compared on the same basis.

Cadbury Bournville

Tesco lists Bournville Classic as dark chocolate with 36% minimum cocoa solids.

  • Tesco lists 60g carbohydrate and 28g fat per 100g for Bournville Classic.
  • Its stated cocoa content does not meet a 70% cocoa preference. Check the exact variant’s ingredients and allergens before buying.

Lindt Excellence

Lindt Shop UK states 70% minimum cocoa solids for its Excellence Dark 70% 100g bar.

  • The declared cocoa content makes the bar identifiable for a 70% cocoa preference.
  • Lindt lists 34g carbohydrate and 41g fat per 100g; compare those figures with your reason for eating before exercise.

Divine

Divine describes its 90g dark chocolate bar as a 70% cocoa product.

  • Divine lists 31.7g carbohydrate per 100g, alongside the stated cocoa percentage.
  • Its listed fat content is 44.3g per 100g, which matters when comparing it with the lower-fat foods favoured in Sports Dietitians Australia’s pre-exercise guidance.

Montezuma’s Absolute Black

Absolute Black is presented by Montezuma’s as a 100% cocoa bar.

  • The stated cocoa percentage answers a specific 100% cocoa preference.
  • Montezuma’s lists 18g carbohydrate and 53g fat per 100g, so it is not a close match for a carbohydrate-focused pre-workout snack.

Questions about chocolate before training

Is high-cocoa dark chocolate a useful main snack immediately before a workout?

It is less aligned with the cited pre-exercise guidance than a familiar, carbohydrate-rich, lower-fat food. Sports Dietitians Australia recommends foods high in carbohydrate and low in fat before exercise; the assessed Lindt 70%, Divine 70% and Montezuma’s 100% bars contain 41g, 44.3g and 53g fat per 100g respectively. If you choose chocolate for its taste, consider whether you already tolerate it at that time before training.

Does “dark” on a wrapper mean at least 70% cocoa?

No. Check the declared cocoa-solids percentage: Tesco lists Cadbury Bournville Classic at 36% minimum, while Lindt Excellence Dark 70% and Divine’s 70% bar state 70% cocoa. The label, rather than the word “dark”, tells you whether a bar meets your cocoa preference.

Can chocolate replace my diabetes exercise plan?

No. If you use insulin or glucose-lowering medication, follow the exercise and carbohydrate plan agreed with your diabetes healthcare team. North Cumbria Integrated Care’s patient guidance discusses exercise-related decisions in an individual care context, not chocolate as a universal choice.

Are school-food and retail-promotion rules for chocolate the same in England?

No. England’s Requirements for School Food Regulations 2014 define confectionery to include chocolate, while Department of Health and Social Care guidance on certain retail promotions addresses a separate retail setting in England. Check the requirements applicable to the particular school setting or retail promotion; do not extend an England-specific conclusion across the UK.
