How is your new year going? Hopefully you're not discouraged or giving up on yourself. Remember this - you didn't get where you are overnight; you're not going to get to where you want to be overnight either.
It takes four weeks for you to notice your body changing, eight weeks for your friends to notice, and 12 weeks for the rest of the world to notice.
Don't give up. In the words of Dora the fish (from Finding Nemo), "Just keep swimming, just keep swimming."
On another unrelated note, here's an article I found interesting about different diets you may hear about. I object to the D-word on principle and hate it in practice, as I'm sure you do too. There is never a quick fix for anything, and your health is no exception.
Lastly, one of my guilty pleasure TV shows is back on the air - "The Biggest Loser." I love my fatties and love watching the transformation they so successfully make - not just physically but emotionally and mentally as well. It may look like their changes are happening quickly and dramatically, but that's the magic of TV. They're not you. These people are morbidly obese and making extreme changes to their bodies. This is NOT normal. Don't get discouraged if you're not able to see such dramatic changes in yourself as quickly as it appears they're making.
This applies to anything - not just health and phsyical transformations. Give yourself time, be patient with yourself, and enjoy whatever you're doing! Keep doing good things!
