How many calories are in a hamburger?

The number of calories in a hamburger vary depending on who prepares it and what types of condiments or other foods are added. For example, a Big Mac from McDonald's contains 550 calories, as reported by Calorie King, while a regular hamburger from Five Guys Burgers & Fries contains 700 calories, according to the corporate website. When consumers prepare their own burgers, they enjoy greater control over the number of calories.

Reducing the calories in a burger could involve scooping out the inside of the bun or substituting whole wheat bread, as stated by Eating Well. Making smaller beef patties or substituting ground turkey for beef can also reduce the calorie count.
