  • After the 1 hour mark, you need to have at least 30 to 60 grams of carbohydrates per hour

Why do I need to individualize my nutritional plan?

09:55 -​

  • There is a lot of misinformation regarding nutrition​, and what you read in the headlines may not apply to you. The person who wrote that headline or news story does not know your individual history, background and any underlying health conditions
  • You need a good amount of high quality carbohydrates
  • You need fluid that is individualized to you based on your sweat rate.
  • You should know your energy and calorie needs so you know if you are eating enough to support your training

What do you need to know to individualize your sweat rates?

12:01 -

  • Get on a scale before you workout, without clothing​.
  • Do your workout, and keep track of how much fluid you consume during the workout, don’t use the restroom during this period.
  • You get back on the scale after the workout and you will see how much you lost and then put that info into the computer to see your sweat rates.
  • Use this spreadsheet to help you with the math of calculating your sweat rate.

How to individualize nutrition for a 40 year old female who is a beginner triathlete and training 5 to 6 hours per week?

13:48 -

  • You need a enough carbs to fuel your training.
  • A good amount would be about 4 to 5 grams of carbohydrates per kilogram of body weight per day.
  • This ensures you have the right amount for training as well as recovering for the next day.
  • A good amount of protein would be about 1 to 1.2 grams per kilogram of body weight.
  • Keep your fat in check, don’t go overboard, but have some healthy fats.
  • For your carbs, include complex carbohydrates, grains (especially whole grains), fruits, vegetables, low-fat dairy, and beans in the 4 to 5 grams of carbs per kilogram of body weight.

Listener question: Are grains and wheat really evil?

15:26 -

  • There is a place for every type of carbohydrate in the diet​.
  • Be strategic and smart on when you are going to have which type of carbohydrate.
  • You need the right kind at the right time. Closer to your workout and immediately after a workout it's okay to have some faster, more refined carbohydrates as the body is going to use them immediately anyway.

How to individualize nutrition for an advanced age-grouper, someone trying to qualify for Kona?

18:04 -​

  • You should focus on carbs because everytime you go out on a 4 to 5 hour bike ride, your body only has 2,000 calories of stored carbohydrate.
  • You need to replace that during the workout or you will either not perform in the workout or compromise how you feel after the ride.
  • If you're training 20 hours per week you will need 9 to 10 grams of carbohydrates per kilogram of body weight spread out throughout the day.
  • Know your calorie level and make sure you are meeting that on a daily basis.
  • Your protein should be around 1.2 to 1.8 grams per kilo of weight per day.
  • Make sure your protein intake is high enough, especially right after workouts.
  • You need 20 to 25 grams of protein and about 75 grams of carbs within that 45-minute window after workout to ensure you are really giving your body what it needs to recover.

Should advanced age-groupers try to emulate what the professional triathletes eat?

20:29 -

  • Pros are often genetically predisposed to great metabolism.
  • We need to focus on our own specific nutrition because unlike the pros, we can't get away with poor nutritional habits.
  • If the pros are eating right, then follow it. Otherwise, it will not work out the same for you.

  • Periodize your nutrition as you would your training
