Time to start looking at the science behind what we are doing – clearly Fat is a great energy source, so lets use it. 

Metabolic efficiency training

The more efficient we are at burning fat, the more we can preserve our limited and precious carbohydrate stores, and the longer and faster we can go before we have to introduce sports supplements.

The body has approximately 80,000 calories stored as fat and only between 1,400-2,000 calories stored as carbohydrate, making fat a huge resource. Once your glycogen (carbohydrate) stores are empty, fat is metabolized into fuel, albeit very slowly and inefficiently—hence the dreaded “bonk.” Fat is a great energy source, as long as you have glycogen or supplemental sports nutrition along with it. Along with the performance benefits, ME training improves body composition and body weight, lowers triglyceride levels, stabilizes blood sugars and improves lipid profiles.

Strategy 1: Food combining
Athletes can work toward better metabolic efficiency by stabilizing blood sugar levels through modifying meal composition. When we eat a plate of carbohydrates (pasta, potatoes, bagels, cookies, etc.) the body releases insulin and suppresses the fat burning system. By eating a combination of carbohydrate, lean protein and healthy fat at each meal and snack, we stay full longer, release less insulin, stabilize our blood sugar and burn fat for energy.

Strategy 2: Nutrient timing
Although athletes benefit from sports nutrition supplements in training and racing, during the off season when the focus is on building a base, additional nutrition support is not needed. By having a metabolically efficient meal or snack before and after your two to three hour easy ride, water and electrolyte beverages are sufficient.

Strategy 3: Smart meal planning
It’s best to get carbohydrates from nutrient-dense whole foods such as fruits and vegetables, keeping your immune system and body healthy and strong. If you’re wondering how to put this all together, read on for a few examples of metabolically efficient meals.
