				What do you think of a diet in which 40% of the calories comes form carbohydrates 40% comes from protein, and 20% comes from fat?

				In 2002, The Institute of Medicine published the Acceptable Macronutrient Distribution ranges (AMDRs) which reflects the range for each energy source associated with reduced risk of chronic disease while providing adequate intakes of essential nutrients such as vitamins and minerals. The AMDRs recommend that 10-35% of your caloric intake come from protein, 45-65% from carbohydrates, and 20-35% from fat. The percentages you are asking about are high in protein and a little low in carbohydrates. While a higher protein intake has not been proven to have any adverse health effects, keep in mind that animal sources of protein are often accompanied by high levels of fat, saturated fat, and cholesterol. Therefore, lean, low-fat cuts and sources are recommended. As for a low carbohydrate intake, carbohydrates are necessary to provide energy to your cells and they provide many nutrients (fiber, minerals, vitamins, phytochemicals) that you cannot find in other food sources. Therefore, an intake of only 40% of your daily calories from carbohydrates may not be enough to adequately fuel your body and meet your nutrient needs.
