 Before you deal with anything, you need to understand what the problem is. So if you say obesity, what do you mean by obesity? So there's what is called the body mass index. So you take the weight of the patient and divide it by the height, the square of the height, which will give you a figure. Now it's expected that ideal weight should be anything. Once you make that, your BMI should be less than 25. Between 25 and 29, you're considered to be overweight. Above 30, you are considered to be obese. Above 35, your person is considered to be morbidly obese. Now all those things come with... And so you see that there are two parameters, your weight and your height. To a large extent, you may not be able to control your height per se, but you can control your weight. So there are different models. So the primary thing there is your intake is far more than your output. Hence there will be storage of the excess as fat. So one, two things you can do. First would be to manage the intake. And I use the word manage, I didn't say reduce, manage the intake. Because some people go like, oh I want to lose weight and then you start to fat fast. And you go like, I'm not eating again. It doesn't work like that. So manage your intake and at the same time, manage your output. So exercise is a very important portion of that. Now of course the other thing there now would be to get checked because there are certain conditions like hypothyroidism and hypothyroidism that affect how the body's hormones manage what is taken into the body. So if there's a problem with any of those, then the person, no matter what you do with those things, there will be a problem. In some cases there's options for intervention, whereby you can do surgery to either reduce the size of the tummy or to put in a balloon just to reduce. And the treatment essentially is based on what level you fall at in that BMI spectrum. It serves as a guide but it's not a hard and fast rule. Usually we start out with very simple things. Modify, manage your diet, exercise, stay healthy, remove your stressors and if there are medical conditions, get them treated for starters. And then you can build on that platform.
