Evidence-Informed Fueling Protocol

RealFUEL+ STRATEGY

Steady Carb Availability
Raw Honey Fuel Source

The Science of Practice

The RealFUEL+ Strategy is built around testing carbohydrate timing, gut comfort, and perceived energy during training. Honey naturally contains glucose and fructose — two carbohydrates that use different intestinal transport pathways (SGLT1 and GLUT5 respectively). Sports-nutrition literature supports practising a fueling plan in training and adjusting intake based on session duration, intensity, sport demands, hydration needs, and gut tolerance.

Diagnostic Objective

Use this page to create a conservative training test plan. The calculator applies published carbohydrate ranges and converts the target into sachets using the carbohydrate amount from your product label.

Fig 1. Published carbohydrate availability guidelines by session duration (ACSM 2016; Jeukendrup 2014). Conservative (lower) and higher-end targets reflect gut-tolerance and intensity context. This is not a clinical blood-glucose model.

Evidence rules applied

  • <45 min: Carbohydrate generally not required.
  • 45–75 min: Small amounts or mouth-rinse may benefit high-intensity work.
  • 1–2.5 h: 30–60 g carbohydrate per hour is broadly supported.
  • 2.5 h+: Up to 90 g/h may be useful for trained guts using multiple-transporter carbohydrate sources.

The 3-Stage Diagnostic Protocol

Priming

Stage 1: The Pre-Load

T-Minus 15 Minutes

1
💧

Fueling Action

Use a small pre-session dose with water if the session is long enough to justify fueling. Log gut comfort and energy.

Testing

Stage 2: Mid-Session

~45 Min / Endurance Zone

2
🍯

Fueling Action

Take fuel gradually and note gut comfort, perceived energy, and whether fluid intake was adequate.

Peak Demand

Stage 3: Late Session

90 Min+ / Threshold

3
🔥

Fueling Action

For longer or harder sessions, test whether the plan holds up near the point where fatigue typically rises. Adjust at next session.

Who This Is For

Test the protocol in training before using it in an event.

Best fit

  • Runs, rides, hikes, or functional sessions over 60 minutes
  • Athletes exploring natural fueling options
  • Training blocks where gut tolerance can be practised

Use caution

  • Medical conditions affecting blood glucose or digestion
  • Pregnancy, medication use, or allergy concerns
  • Race day without prior training practice
