Healthcare professionals these days recommend raw celery for those who suffer from obesity and its associated health problems. This is because celery is a leading thermogenic food. High water content and fiber in celery enhance the pace of weight loss naturally and safely. Vitamins and minerals in celery increase the energy level and keep people active throughout the day. People who consume a cup of raw celery sticks get 16 calories. However, they get all healthy nutrients required for weight loss. The theory is that you can lose weight by eating lots of these negative-calorie foods. Celery is a commonly cited example because it’s mainly water and fiber. Proponents claim that you will burn more calories digesting celery than it contains, for a net loss.
