So you’re training most days, putting in everything into every workout. Doing some mobility and skills work at home. Your logging your workouts and watching every available video on CrossFit you can find. But despite all this you are still only doing CrossFit by half. Why?

In Greg Glassman’s Fitness in 100 Words he starts it with the paragraph. “Eat meat and vegetables, nuts and seeds, some fruit, little starch and no sugar. Keep intake to levels that will support exercise but not body fat.”

·         There is a reason it’s written that way. This is because fitness and health is determined not only by what you do with your body but also by how you fuel it. If you think that you can train harder to justify a poor diet then you are sadly mistaken. When I say this I’m not only talking about body composition such as weight and body fat. I’m also talking about your health and performance. Your nutrition has a huge influence on these factors, your risk of chronic disease your ability to grow muscle to minimise inflammation and to be able to deliver optimum performance is massively determined what you eat. Every cell in your body relies on being fuelled with the correct macro and micro nutrients. For a simple example of having a poor macronutrient balance if you are deficient in protein you can suffer from the following:


·         A sluggish metabolism

·         Trouble losing weight

·         Trouble building muscle mass

·         Low energy levels and fatigue

·         Poor concentration and trouble learning

·         Moodiness and mood swings

·         Muscle, bone and joint pain

·         Blood sugar changes that can lead to diabetes

·         Slow wound healing

·         Low immunity


For micronutrients having a healthy dose of omega 3’s can help reduce inflammation, help with fat loss, brain function and even may have an anabolic effect to help grow muscle.

These are just a couple of examples of areas where your nutrition may be lacking. This combined with excessive starchy carbohydrates, sugars and alcohol will again cause health and performance issues.

Lots of people tell me they eat well most of the time but often under a more thorough analysis the reality is quite different to the perception. I’m going to talk further about how we can improve diets in future blogs but for now go away with one key thought.  Rather than adding an extra training session into your week (for example Sundays is are off day here at CrossFit Chiltern) use the hour you would work out that day to plan and prepare your meals for the week. Make one of your weekly WODS (workout of the day) a food planning WOD.
