I gave up explaining to people why I did this. I agree with Swizzly, time will show him there is nothing "easy" about this route. It's a major and drastic approach to weight loss. But I will add, exercise plays a great role if you want to take full advantage of the procedure. Find something you like.
For me it's walking. It's easy, simple, effective. I never liked to exercise, because I got tired so fast, could not do much, and felt so self- conscious at the gym. But the more I lose, the more I am able to do, the more I want to do. I put on my favorite music and just get going on the treadmill or the park.
Good luck on your journey.
