There is plenty of studies that show more and more people are getting overweight or severely obese every year. The numbers are quite alarming and even young kids who are just starting going to school are getting more and more overweight. This is probably one of the main reasons why people are now obsessed with rapid weight loss diets as well as pills.
The cause of obesity used to be genetics or part of a natural aging process that occurs as people age and as the metabolism slows down, making it harder for older people to burn the food. Now even factors like overeating and bad unhealthy diets filled with fast food that are full of sugar, salt, fats and processed ingredients.
