Most athletes today still consume too much carbohydrates, too little protein and usually too little or about the right amount of fat, but from the wrong sources. Now, I’m not advocating a low carb diet for athletes, only a more sensible approach with a more balanced macronutrient breakdown combined with proper nutrient timing.
My first encounter with separating and timing macronutrients (apart from post workout nutrition) was in 1998 when I discussed this topic via e-mail with Don Lemmon (rest in piece, my friend). Don had a lot of ideas; some crazy and some good. In 2000 I wrote about separating fats from carbs and to consume meals containing lean proteins, vegetables and fats during the day with carbs only around the workout. This article got a more detailed follow-up in Exhale Magazine in 2003 (it’s called “Att äta på rätt sätt“, and is still available in Swedish on this website).
In that article I laid the foundation for sensible healthy nutrition and I still build my nutrition programs from that same foundation. We all have the same basic needs, but how we live and exercise calls for individualization of that foundation.
When I meet with endurance and/or performance athletes they usually get between 60 to 70 percent of their energy from carbohydrates, and most of those carbs come from high-starch and high-sugar foods. That’s just plain mad! But that’s not all; they don’t know zilch about nutrient timing either.
Actually, those athletes will perform much better, and improve their health considerably, when they adjust their carb intake to 40 to 50 percent of their total daily calories.
Usually, I start most of them out on 40% carbs, 30% protein and 30% fat. After that I might increase the carb up towards 50% or even 55% if they have excellent carbohydrate tolerance. If someone does, I might bring his fat down to 20%, but most of the time fat intake will stay between 25-30% with proteins filling up the rest.
It’s also important to understand that protein (especially BCAA) is needed for recovery. By consuming high amounts of protein (compared to the old outdated recommendations), athletes can rapidly reverse the breakdown of muscle and thereby reduce recovery time and train at a greater intensity at the next training session.
Now, the key here is nutrient timing. Most of these carbohydrates should be consumed around your training. Your body can handle carbs much better during and after a workout. Your muscles can refill and build up all the glycogen they need when they get starch and sugar in the immediate post-exercise window following a training session. Eating carbs all day long will not result in better filled glycogen stores. It will only contribute a high insulin load, fluctuating energy levels and several modern diseases such as diabetes, inflammation, obesity and other chronic diseases.
During the rest of the day, all meals should be built around lean proteins (lean meat, fish, poultry, eggs etc), colorful vegetables and healthy fats (equal parts from monounsaturated, polyunsaturated and saturated fats). Add one or two pieces of fruit a day and your all set.
Guess what? This is actually the same underlying concept I use when I design nutrition program for bodybuilders and power athletes as well.
