Well, 1g of carbs or proteins provides 4 calories of energy. The only other source of energy are alcohol and fat. Alcohol provides 7 calories of energy per gram and fat provides 9 calories of energy per gram. So if you want over twice the amount, then the only option is fat.
look at the nutrient info thing :)
malnourishment is most commonly caused by poor nutrient intake, not calories (at least in the U.S.A). Many people are considered malnourished but are actually overweight, because they consume food with a poor nutrient density (foods that do not have a wide variety of nutrients, usually high in fats and calories).
The United States Department of Agriculture has a "National Nutrient Database" which contains details of calories and nutrients in many different foods. http://www.nal.usda.gov/fnic/foodcomp/search/
One cup of cooked broccoli contains approximately 55 calories. Raw broccoli has even fewer calories, with about 31 calories per cup. This makes broccoli a low-calorie, nutrient-dense vegetable, rich in vitamins, minerals, and fiber.
You should eat about half of what you burn during that workout. If you burn 1,000 calories, you should have consumed about 400-500 calories to last long enough to burn twice that amount.
It depends on how many calories a person needs a day. Also on what activities the person does daily.
5 oz glass of pinot noir red wine (147g) has 121 calories.
