So if you normally burn 1750 calories per day (10,500 calories per week) and you want to lose 1 pound of weight per week, you need to reduce your calorie-intake by 3,500 calories - or, 500 calories per day. This means consuming about 1250 calories per day.Fat contains 9 calories per gram, while protein and carbohydrates contain 4 calories per gram.
There is not an actual RDA (recommended daily allowance) for carbohydrates. Between 50 and 55 percent of a person's calories should come from carbohydrates, which are your body's main fuel source. Include whole grains, fruits, vegetables and low-fat dairy products into the daily diet. For example, if you eat 1,250 calories a day, you should have about 125 grams of carbohydrates a day (based on 50 percent of the calories coming from carbs).
