Burgers are not better than hot dogs because like you really can only eat two burgers because they are so big. You can eat 2 hotdogs instead of eating 1 burger for the people who love to eat because everyone loves food. But burgers sometimes are raw and hot dogs can't really get raw.
Even though burgers are not healthy for you, they provide a good source of protein and they don't have a lot of sugar in the burgers. Also , you can add more toppings than rather just putting ketchup on it.
