Many people who go on a low calorie diet are looking to cut as many calories out of their diet as possible. While this is good, people should also realize that they need to ensure that their diet is still healthy for their body weight. That means that those who are becoming calorie obsessed should take care not to cut too many calories out of their daily diet. Before you decide what your daily calorie count is, you really need to take the time and figure out the least amount of calories you need to have for your age, weight and height. In the event that you decide to go lower than those calories you should promptly consult your doctor.
