Why do so many thin people drink Starbucks all the time when each drink is approximately 500 calories?

Specialty coffee drinks, like those sold at Starbucks, are high in caffeine, which gives energy, and perks drinkers up. They are also filling. So, if all you have is one drink, and replace a meal with it, you will not gain weight. Also, it is trendy to drink high-end coffee drinks. Keep in mind that the number of calories in coffee depends on the type of coffee drink. Espressos have 5.4 calories and black coffee possibly 10 or less. Its the lattes, cappaucinos and hot chocolates that have a lot of calories.
