There are two answers. If you are making the food yourself, you go on a site like this and find out the calorie count for the individual ingredients, add them up, and then divide the number of servings into that number to get the single serving calorie count.
For instance, I just made peanut butter cookies and wondered how many calories in each cookie. There are five main caloric ingredients--Sugar, 775 calories per cup; Flour, 1000 calories per 2 1/2 cup; Peanut Butter, 1520 c. per cup; Butter, 1600 c. per cup; and Eggs, 150 c. for 2 large eggs. The total of all that is 5045 calories. I divided that by 73, the number of cookies the recipe made, to equal about 69 calories per cookie.
It's pretty hard to find out the calorie count in store-bought food without the panel of nutritional information on the side of the box. You could call the manufacturer and they'd tell you. A lot of restaurants are posting the caloric content of their foods on menus.

(q=Heat in calories or joules) (T=temperature) (ΔTwater=Tfinal-Tinitial) (spefic heat of water= 4.18 J/g °C)
(Masswater = Mass of water in box - mass of box w/o water)
(joules to calore conversion 1 calorie=4.184 Joules)

∙ 13y agoIf you are eating processed food the number of calories per serving should be listed on the package under "Nutrition Facts". If you are eating at a restaurant, you can ask to see the nutrition facts of the food you want to order or you can check online before you go out to eat. Most restaurants show the nutritional information of their different food choices on their website.
If you would like to keep track of the number of calories you consume daily, there are many Calorie Count websites out there that will help you with that. See the Related Linksbelow.

Does cooking add calories to food?
Answer- It depends whether or not you're adding something caloric to your food! If you fry it, yes. Oil/shortening contains calories. Eating food+oil contains more calories than the food alone. If you boil it in water, no. water has no calories. Heating the food in an oven or microwave will not add any calories. It is important to remember that food preparation certainly can change the nutritional values of a foodstuff. When you start adding caloric items such as butter or sugar to a product, (surprise, surprise) you'll end up with more calories to the finished item. Sometimes, especially in the case of salads, added dressing or cheese can end up having many times more calories than the vegetables themselves. Be aware of this when making food choices.
