Evidence-based performance fueling: high carbs scaled to training load, moderate protein, lower (not low) fat. Sports-nutrition consensus, not a health philosophy.
High Carb Athlete is a performance-fueling approach for people who train. The pattern is high carbohydrate scaled to training load, moderate protein, and lower-but-not-low fat: built to fill glycogen stores, power high-intensity and endurance work, and speed recovery. It comes straight from the mainstream sports-nutrition consensus, the way endurance and high-volume athletes are actually advised to eat.
The framing matters. This isn't a health-vs-disease philosophy and it isn't a universal "best diet." It's the evidence-based answer to a narrower question: how do I fuel hard training so I can do more of it, perform on race day, and recover in time to go again.
Muscle and liver glycogen are the limiting fuel for high-intensity and prolonged exercise. Run low and you feel it: legs go heavy, output drops, the session falls apart. Carbohydrate is the body's premium fuel for hard training, and this preset is built around that fact.
This is the central principle. Carbohydrate needs scale with how much and how hard you actually train. It isn't "eat carbs constantly," it's "fuel the work you're doing." Hard day, more carbs. Easy day, fewer carbs. The numbers below make that concrete.
Carbohydrate availability around training is the point: fuel before the session, top up during long ones, refill fast after. The same daily carb total spread carelessly performs worse than one timed around the work.
This is the evidence-based way to fuel athletic work, distinct from the app's health-framework presets. It answers a specific question, how do I train and recover better, rather than "what is the universally best way to eat?"
Hit your carbs from quality whole-food sources: rice, potatoes, oats, fruit, bread, pasta. Sports drinks and gels earn their place around long sessions and fast recovery, not as the default. Keep fat sources whole, the app's low-PUFA principle still applies, you don't need seed oils to eat high-carb.
Glycogen binds water, roughly three grams of water per gram of glycogen. Loading up can add a few pounds on the scale, that's stored fuel sitting in the tank, not fat gain. Race-day legs feel full for a reason.
The clearest, most useful piece of the sports-nutrition literature is the carbohydrate-by-training-load guidance. These are daily ranges in grams of carbohydrate per kilogram of bodyweight, the way Burke and others present them, with the band you sit in depending on what training actually looks like that day.
~8 to 12 g/kg/day for 24 to 48 hours before the event, while tapering training. Favor easy-to-digest, higher-GI carbs, race-day legs want fuel, not fiber.
~30 to 90 g of carbohydrate per hour, with well-trained guts pushing up toward ~120 g/h. Glucose-fructose mixes absorb best, this is largely Jeukendrup's research.
~1.0 to 1.2 g/kg of higher-GI carbohydrate per hour for the first ~4 hours to refill glycogen fast. Glucose-fructose combinations refill liver and muscle best, and adding protein (roughly a 3:1 carb-to-protein recovery meal) speeds glycogen repletion and supports repair.
~1.4 to 2.0 g/kg/day, spread across meals. Enough to support training without crowding out the carbs that actually fuel it.
Fills the rest of the calories, generally ~20 to 35% of energy. Not below ~20%, fat is still needed. This is high-CARB, not no-fat.
Numbers reflect the sports-nutrition consensus (Burke, Jeukendrup, ISSN, GSSI). They're targets to fuel training, not medical advice, and they assume you're actually training.
The signature trio: rice, potatoes, banana. Around them sit oats, bread, pasta, and other whole-food starches, fruit and fruit juice for portable fuel, and sports drinks or glucose-fructose mixes for long sessions and fast recovery. Quality protein and whole-food fats fill the rest of the plate.
Here's the shape of a HIGH training day, a long or hard session as the centerpiece. Carbohydrate is timed around the work: loaded before, sipped during, slammed after, then continued through the day to keep refilling. On an easy day or rest day, the same person scales the carbs down. That's the periodization principle in practice.
Oats with banana and honey, or rice with eggs. A coffee. Carbs loaded before the work so the tank is full when the session starts.
Carbohydrate on the move, a sports drink, a banana, a glucose-fructose gel or chew. Aiming roughly 30 to 90 g of carbohydrate per hour, more for the well-trained gut.
A higher-GI carb plus protein meal or shake within the recovery window, roughly a 3:1 carb-to-protein ratio. Rice with chicken and fruit, or a recovery shake. The goal is refilling glycogen fast.
A big carb base, rice, potatoes, or pasta, with lean protein and vegetables. The plate genuinely looks like a third of it is starch.
Fruit, yogurt, a sandwich. More carbs to keep refilling between sessions or before tomorrow's work.
Another generous carb portion, potatoes, rice, or pasta, with protein, whole-food fats, and vegetables. Hydration with electrolytes through the day given sweat losses.
The same person eats noticeably fewer carbs, the lower end of the daily band. Carbohydrate is periodized around training, not held constant. Heavy day, more carbs. Easy day, less.
Honest framing: this is mainstream, well-supported sports-nutrition science for fueling athletic performance, but it's performance guidance for athletes, not a universal best diet for health. Not medical advice.
High Carb Athlete isn't one person's framework. It's the mainstream sports-nutrition consensus, drawn from the AIS, ISSN position stands, Jeukendrup's lab, and the GSSI's hydration and fueling work. The carb-by-training-load numbers, the during-exercise targets, the post-session recovery ratios, all come from that body of research.
One of the most cited voices in sports nutrition. Her work shaped the carbohydrate-by-training-load guidance the preset is built on.
Carbohydrate-during-exercise research, including the glucose-fructose absorption work that underpins the 30 to 90 (and up to ~120) g/h targets and modern sports fuels.
