Weight Loss Affiliate

My friend/colleague wants to lose some weight just like me. To be able to do it we are going to sign up into weight loss affiliate. When we mentioned it to our colleagues at work we were surprised that even that our slim colleagues would love to join us. Now this gives me more pressure. They said that they are not trying to shed some pounds but to maintain their health. I really need to do it because right now I am suffering with short of breath because of my heavy weight. Sigh...
