Most of us don’t run more than two marathons a week or work out at all hours of the day, so this way of eating is not recommended, even for high school and college players and people who exercise regularly. However, this information certainly brings into question traditional thinking and, as so often with these studies, leaves us wondering if this type of eating could benefit other types of athletes or moderately active people. We’ll need to continue to watch the research for more answers.
It’s important to remember that carbohydrates are an essential part of a healthy, well-balanced diet and provide fuel for your workouts in the form of glycogen, which is stored in the liver and muscles. Fat, however, must be broken down into fatty acids before it can be used as fuel, and only endurance athletes who vigorously exercise throughout the day are able to use up all their glycogen stores before their bodies start using fat. A ketogenic diet, like the ones the article reviews with 85 percent of the diet from fat, forces your body to use fat more readily as an energy source. This is referred to as a ‘ketoadaption’ and takes several weeks to achieve.
Still, it’s not a good idea to overdo it on carbohydrates or fat for all your meals. Fats should only comprise 20 to 30 percent of your total daily calorie intake per meal (think two slices of avocado). Carbohydrates should make up 40 to 50 percent of your meal, and sources of good carbohydrates include vegetables, fruits, legumes, and whole grains. Government experts have offered suggestions for the 2015 Dietary Guidelines, (due to be published in the fall) which encourage Americans to cut down on meat, added sugars, and starchy, high-carb foods and include more fruits, vegetables, whole grains, and healthy fats into their diets.
