What is simple for some is not so simple for others, and it certainly can become more difficult once you've passed a certain stage. I can't bring myself to shit on these people for leaning on an aid to help them, but if it makes others feel better to do so, go off, I suppose.
The problem is that people want to lose the weight it took them 10+ years to gain, in 3 months. That's just not possible. It took a long time to put it on, it's going to take a long time to take it off the natural way.
Taking the shortcut of taking a drug to lose weight is not going to teach you anything. It's not going to make you change your eating habits and eat a healthy diet.
It's the same thing as fad diets. All of this is a temporary solution to a long term problem. It doesn't work out long term. But I'd argue that taking a drug is much worse than a crash diet, due to all of the side effects.
Instead of giving these people drugs, why don't we just educate them on the healthy way to lose it through exercise and diet, which is a lifestyle change that will be better for them long term?
And yes, I'm sorry, it is sheer laziness for about 99% of the people out there who got fat and are trying to lose weight, but can't stick to a plan of diet and exercise to lose it.
Exercising is called "working" out for a reason. It takes work. And work isn't always fun or easy. But it's doable for everyone.
