About it

Black Cat Smooth Peanut Butter is a high-energy spread primarily composed of peanuts, providing a rich source of fats and proteins. For endurance athletes, this product serves as a dense energy source with 96.6 kcal per 15g serving. While it offers 3g of carbohydrates per serving, its primary macronutrient is fat, at 8.2g per serving, which can be beneficial for long-duration, lower-intensity activities where fat oxidation is prioritized. The protein content of 3.9g per serving supports muscle repair and maintenance. Due to its high-fat content, it is best consumed well before or after intense sessions to avoid gastrointestinal distress. Its natural peanut oil content contributes to its smooth texture and provides essential fatty acids. However, its low carbohydrate content makes it less suitable for immediate energy needs during high-intensity workouts.

For endurance who it suits

Endurance verdict

Black Cat Smooth Peanut Butter is a dense energy source suitable for long-duration, low-intensity activities. Its high-fat content supports fat oxidation, making it beneficial for ultra-endurance athletes. However, it lacks the quick-release carbohydrates needed for high-intensity efforts or immediate pre-race fueling. It is best used as a supplementary energy source or recovery snack.

Who it is for

Black Cat Smooth Peanut Butter is ideal for endurance athletes engaging in long-duration, low-to-moderate intensity activities where fat oxidation is a key energy pathway. It's suitable for those who require a calorie-dense food source to meet high energy demands, such as ultra-endurance runners or cyclists. Athletes looking for a protein-rich snack for muscle maintenance will also benefit.

Best sessions

This peanut butter is best suited for long, steady-state sessions like ultra-endurance events or long training rides where fat metabolism is a primary energy source.

Pros
  • High in energy and healthy fats
  • Provides a good amount of protein
  • Natural ingredients with minimal processing
  • Versatile for various dietary needs
Cons
  • Low carbohydrate content for immediate energy
  • High fat may slow gastric emptying
  • Not suitable for mid-race fueling
  • Limited sodium for electrolyte replacement
Watch out for
  • Potential for gastrointestinal discomfort if consumed pre-race
  • High fat content can delay gastric emptying

Fuelling science in short

During a session

Not recommended during workouts due to high fat content, which can slow gastric emptying and lead to gastrointestinal discomfort.

Glycaemic profile

With 3g of carbohydrates per serving, the glycemic impact is minimal. The high fat content slows gastric emptying, providing a sustained energy release rather than a quick spike.

Electrolytes

Contains 20 mg of sodium per serving, which is minimal compared to the 300-600 mg/hr sweat loss in endurance athletes. Potassium content is unspecified.

  • Every dayUSE

Black Cat Smooth Peanut Butter is not suitable for pre-race or during-race fueling due to its high fat content, which can slow gastric emptying and provide insufficient quick-release energy. It can be cautiously used for recovery if paired with carbohydrates to support glycogen resynthesis. Its high energy density makes it suitable for everyday training as a calorie-dense snack.

NOT RECOMMENDED for pre-race use because its high fat content can slow gastric emptying and lead to gastrointestinal discomfort, which is undesirable before a race.

Pair it with
  • Pair with a banana for quick carbs and potassium.
  • Combine with whole-grain bread for a balanced macronutrient profile.
  • Add to a smoothie for a calorie-dense recovery drink.

For practitioners the evidence

Evidence grade: B — Supported by sports nutrition guidelines and studies on fat metabolism and gastric emptying.

In a carb load

Black Cat Smooth Peanut Butter is unsuitable for carb loading due to its low carbohydrate density of 18g per 100g. A 15g serving provides only 3g of carbohydrates, contributing minimally toward the 600-840g daily target for a 70kg athlete. The high fat content may increase satiety, making it impractical to consume in large quantities without exceeding fat intake recommendations.

Digestion and absorption

The high fat content in Black Cat Smooth Peanut Butter slows gastric emptying, delaying the time it takes for nutrients to reach the small intestine. Once there, proteins are broken down by brush-border peptidases, while fats undergo emulsification and absorption. The minimal carbohydrate content is absorbed via SGLT1 transporters. The high fat content may delay the insulin response, providing a slower release of energy.

Recovery

While Black Cat Smooth Peanut Butter provides some protein (3.9g per serving) for muscle repair, it lacks sufficient carbohydrates to meet the 1.0-1.2g/kg/h target for glycogen resynthesis in the first 4 hours post-exercise. Its high fat content does not contribute to immediate recovery needs and should be paired with a carbohydrate-rich food for optimal recovery.

Downsides

The high fat content may cause gastrointestinal distress if consumed close to exercise due to slowed gastric emptying. The low carbohydrate content limits its use for quick energy needs. High fat foods can also pose a dental risk if consumed frequently without proper oral hygiene. Athletes with peanut allergies should avoid this product.

Don't use it when
  • Do not use within 90 minutes of race start due to high fat content.
  • Avoid during high-intensity sessions needing quick energy.
  • Not suitable for those with peanut allergies.
Clinical risks
  • High fat content may slow gastric emptying and cause GI distress.
  • Low carbohydrate content limits quick energy availability.
  • Potential for allergic reactions in individuals with peanut allergies.
  • Frequent consumption without oral hygiene may increase dental caries risk.
