Hi Alisson welcome to the Forum.
No Alisson I don't think he is worth listening to because he is still trying to work it out himself.
He continues to regain the weight he has lost and hasn't figured how to make it permanent. In 2007 he was 255lbs (115.9kg), in 2010 he was 292lb (132.7kg) and in 2012 he was 295lb (134kg)...notice that with each regain he has put on more weight. Each cycle is about 2 years long and at the moment he is about half way through this cycle (nearly lost it - and ready to put it on again).
He has figured out the mechanics of weight loss (most of which are common sense and readily available elsewhere) but doesn't understand how to keep it off. He seems to be more about revealing his hidden (by fat) abs and enlarging his public profile than what is the most important factor of all - creating a healthy lifestyle that works in his life forever.
He seems to believe it is about motivation and will power. Whilst being motivated and having will power will help in the short term these things will fail (and his life shows that they fail). What is required is character transformation. Becoming the healthy person you should be. That means fundamentally change the core of your very being. Change is the price you have to pay for permanent success - that's a price too dear for some.
I would stack up my credentials against his any day. Like him I too started out not knowing a thing. Unlike him I started out close to my 52th birthday - with a bad back, chronic asthma, belly hernia and ingrown toenails. My starting weight was 338.9lb (153.7kg) and after exactly 60 weeks I weighed in at 146.8lb(66.6kg). This was the only time that I have attempted to lose weight in my entire life and have kept it off for 2 and a half years now. I think my track record is better than his wouldn't you say? Check out my photos in the Before and After Photo Section of this Forum for visuals. So you see that I'm not just talking the talk - I'm walking the walk as well.
