NUTRITION WHY’S #22: CARBS, FATS, AND PROTEINS- Don’t think of carbohydrates, fats, and proteins as three separate categories. They can be converted to each other. The body has metabolic pathways that allow them to be converted so that in starvation or prolonged exercise, the fat is burned first to satisfy calorie needs together with small amounts of carbohydrate. Once the carbohydrate is gone in three days of starvation or 22 miles of running with no extra carbohydrate eaten, body protein becomes the only source of carbohydrate which is needed by all organs in the body but especially the brain and red blood cells. Over time most organs adapt to using fat for energy by burning ketones in without carbohydrates being available except fro the brain and red blood cells. While forced to use protein, the body continues to try to conserve protein until when 1/2 is gone, the immune system shuts down. Even simple infections can be fatal in this condition. Luckily you most likely are not worried about starvation. As a healthy or overweight person, extra calories you eat of any macronutrient will be converted to fat. Next time we will talk about what you should eat from each of protein, fat, and carbs categories for Balanced Nutrition and a Healthy Active Lifestyle!!#drdavidheber #protein #fat #carbs #exercise to learn more go to www.drdavidheber.com and www.herbalifenutritioninstitute.com
