There are some great articles about nutrition on the hammer nutrition website that I recommend that everyone check it out. Or you can get the summery from me J
A problem I have always thought about was how many calories do I need for each session to optimize performance and not get fat? After some experimenting and research, I believe I have found the solution thanks to the Hammer Nutrition website and Steve Born’s Article. Less Is Best- The Right Way To Fuel – http://www.hammernutrition.com.au/info-centre/less-best-right-way-to-fuel/
It’s a very interesting article that discusses the myths on fuelling and how the body can only use and consume a certain amount of energy efficiently per hour and overconsumption (more than 300 calories/hour, may lead to “stomach shutdown” and inhibit performance. I found the following table very helpful.
|Loss vs. AssimilationWhat can your body really handle?|
|SUBSTANCE||RATE LOSS/hr||ASSIMILATION RATE|
|Fluids (ml)||1000-3000 (30-90 oz)||500-830 (17-28 oz)|
|Below are the corresponding replenishment values that we have observed for the averagesize endurance athlete (160-165 lbs/72.5-75 kg) who is fit and acclimatized (+/-5%):|

If you want more details, follow the link to the artical and remember these are guidelines and every individual’s needs and situation may be varied. What I like to use in my longer sessions is a mix of Hammer Endurolytes Fizz tablet in water and Hammer choc chip bar. And Hammer Gels and Hammer Perpetuem in water.
