Course overview

2

Carbohydrates are the athlete's main fuel

Carbs are fuel; more carbs usually means better performance

3

Calories are not all the same fuel

Carbs, fat, and protein each behave differently during exercise

4

Fuel use changes with intensity

Low intensity burns fat; high intensity demands carbs

5

Ketones: sometimes fuel, sometimes useless

Ketones can power easy efforts but stall at high intensity

Unit 2

Why keto and carnivore fall short for hard sport

Strong evidence beats one person's good feeling

Carb timing: four hours before training

Far out from training, eat slow-digesting complex carbs

Carb timing: one hour before, and during

Close to training, switch to fast simple and liquid carbs

Why protein, fat, and fiber backfire right before training

Heavy, slow foods before hard effort cause gut trouble

After training: carbs plus protein

Refuel and rebuild together, like chocolate milk

Unit 3

Carb loading: when it helps and when it hurts

Loading carbs helps endurance but slows power athletes

How to actually carb load (and train your gut)

Real loading is a lot of carbs, and your gut needs practice

Hydration and reading your urine

Urine color tells you whether you need water or salt

Water beats electrolyte supplements for most people

Most athletes already get plenty of sodium

Food covers your other electrolytes

Magnesium, potassium, and calcium come from fruit and veg

Unit 4

Creatine 101: what it is and the dose

Creatine monohydrate is the best-evidenced legal performance aid

Creatine: safety and common myths

Creatine is safe for most people; timing and loading do not matter

Creatine: powder and tablets, not gummies

Creatine breaks down in liquid, so avoid gummies

Caffeine: alertness, not energy

Caffeine sharpens you but is not fuel; dose and time it right

Sleep is a performance tool

Bad sleep hurts performance, recovery, and weight

Unit 5

Aspartame and artificial sweeteners are safe within limits

Diet sweeteners are safe at normal intake and can help fat loss

Sustainable fat loss, no gimmicks

Small deficit, high protein and fiber, lift, walk, sleep

Common mistakes to unlearn

The classic sports-nutrition traps in one place

Nutrition for concussion recovery

A healing brain needs more energy, omega-3, protein, and color
