What is REDs?
RED-S (Relative Energy Deficiency in Sport) occurs when energy intake doesn’t meet the energy expended through exercise and daily life.
While REDs is about total energy, carbohydrates play a critical role because they are the primary fuel for cognitive function, recovery, hormones, and everyday movement, exercise, training, and activity.
The RED-Scue Philosophy
Across cultures and sciences, the same truth appears in different language:
• Sports science calls it Low Energy Availability (RED-S)
• Traditional Chinese Medicine calls it Qi deficiency
• Ayurveda calls it low Agni and low Ojas
• African endurance cultures simply fuel for volume with carbohydrates
Same root problem: not enough usable energy.
RED-Scue exists to bring fuelling back to basics:
Real food.
Enough carbohydrates.
Consistent energy.
Built from lived experience with RED-S and LEA.
What is LEA?
Low Energy Availability (LEA) happens when your body doesn’t get enough fuel for the work you demand of it. Over time, this becomes RED-S, affecting:
• Energy levels
• Hormones
• Bone health
• Immunity
• Performance & recovery
The main macronutrient missing?
Carbohydrates.
Most runners, HYROX athletes, team-sport players, and busy professionals simply don’t eat enough — putting themselves at risk.
RED-Scue exists to make fuelling simple, practical, and culturally grounded — without fear of carbs, diet culture, or ultra-high-protein sports products that can often upset the gut.
RED-S impacts 67% of people and low carbohydrate intake impacts 95.8%

~ Only 4% of elite athletes meet carbohydrate needs (Melin et al., BJSM)
~ 95.8% of active people are under-fuelling (Hackney et al., Int J Sports Physiol Perform, 2025)
~ Low energy availability is the driver of RED-S, disrupting hormones, glucose control and recovery (Mountjoy et al., IOC Consensus)
Yet...
Carbohydrate + adequate energy intake preserves glycogen, stabilises blood glucose, improves recovery and protects performance (Jeukendrup 2011; Clinical Nutrition ESPEN 2025).
