Using products to lose the weight

I was talking to a guy at the gym and he was talking to me about all of the stuff that he wants to buy and currently using to lose weight. He rattled off three things that he is taking which he relies on everyday and I just thought to myself that if he spent that money on healthy foods and more natural alternative, he would lose weight. So many people are dependant on chemicals to do the job quicker and easier with little to no work. Sometimes this makes me sad to know that the world will eventually become weaker body and mind and become the end to our world.
