Stop looking for the magic bullet, the achieve optimum weight AND TO MAINTAIN it one has to get healthy first, but what is true health?
The media and the fat cats don't want the masses to become healthy otherwise too many would live for too long and pensions must be paid!
The fat cats with their big corporations want you to rely on supplements, drugs, their cheap and addictive food and toxins to make money IN 25 years drinking water will be more expensive than petrol, imagine how much money there is to make by selling bottled water. Why is that when doctors prescribe a course of anti-biotics most of the time they don't suggest you taking probiotics after you got better?

  

Anti-biotics wipe out bad and GOOD bacteria in the gut so you are left with an even weaker immune system, probiotic supplements and foods recolonize the gut with good bacteria so again why are we not advised to eat buttermilk (kefir), sauerkraut and other fermented products?
Maybe without a strong immune system chances are bigger you stay sick and buy more drugs. Stomach problems, depression, headache, flu and stuff that can be treated (not healed) with over-the-counter drugs are fairly cheap and heavily advertised on TV and other media and of course if you are not 100% healthy you are not 100% happy either, mood swings can be nicely treated (not healed) with things like shopping for clothes and gadgets, entertainment, anything that gives you a kick will do because your body can't produce happiness hormones meanwhile stress, cheap sugary and fatty food and the lack of physical activity makes many ill and fat and unhappy.
 If you think you want to start fresh in the new decade, make a change for yourself then its time to get selfish and do what is good for you, plenty of information is out there, self-help books, websites and even organizations so you can start your journey. I personally recommend the following sources :
