Of late there’s been a lot of attention paid to different diets/philosophies on food. Among the popular philosophies out there are the Paleo diet, the Atkins diet, the Zone diet, the South Beach diet, the Mediterranean diet, and more. One interesting similarity these diets have is a higher proportion of fat and protein than the typical American diet which is very high in carbohydrate. In reading research studies and speaking with people who’ve tried various dietary modifications one thing stood out; people who eat lots of carbohydrate (60+% of total daily calories) tend to burn carbohydrate during exercise and throughout the day whereas people with less carbohydrate consumption (50% or less of total daily calories) tend to burn more fat. Then along came the idea of Metabolic Efficiency Training, put forth primarily by Bob Seebohar, MS, RD, CSSD, CSCS (http://www.fuel4mance.com). In this method of eating, you focus on proteins, h ...

Being a physiologist and athlete, I know the value of regular laboratory testing to dial in training zones, pacing strategies, and fueling strategies. At BCSM we offer a test called the F.U.E.L. test. The F.U.E.L. stands for Fuel Use Evaluation with Lactate profile. In this test we are looking at your total caloric expenditure as well as the amount of fat and carbohydrate being utilized by the body in addition to looking at your lactate profile to determine your optimal training ranges and predict race paces. Knowing all this data, we can then assist you in planning how many calories you should consume during long training sessions and races. The F.U.E.L. test provides a ton of information that is invaluable to any athlete looking to improve performance in races lasting longer than 2-3 hours. Above are the results of a 2008 F.U.E.L. test I performed. Note that at 8:06 min/mi pace I burn nearly 1000 calories per hour, 740 from carbohydrate, 216 from fat. Knowing that I can ...

For a few years I’ve been dabbling in ultra-running and run a handful or 50 and 100 mile races in that time. My biggest struggle has always been fueling for these long races. In my first 50, I ran 30 miles without eating, because I could not hold any calories down at the pace I wanted to maintain. Needless to say I ended up walking 15 miles in a hypoglycemic haze then stopped and ate at the last aid station. I felt miraculously wonderful after eating, and ran the last 5 miles well, probably the best I felt the entire race. In later ultras I experimented with different fuel sources: drinks, gels, solids, real food, more salt, less salt, etc. I learned how to calm an unsettled stomach with Tums, ginger, Coke, etc. but the reality of the situation was, I can not consume enough calories while running the pace I want to run to sustain that pace. The only solution then, was to run slower, and I still dealt with some severe GI issues on my first 100 miler (first bathroom brea ...
