First off change your name! You need to start thinking positively about your self! FatBlubber? Bahh!
How about Soon2BSvelt?
You don't want to lose a lot of weight FAST, you just think you do, but if you go on some crash diet you WILL gain it all back.
Also, do not go on "A diet" you need to change "Your diet". Start small, maybe choose mustard over mayo, get wheat bread over white, start drinking diet/low cal soda and start walking around with a water bottle. Sometimes hunger is thirst in disguise.
Does you family eat cr@p all the time? Is there anyway to limit how much empty calorie food come into the house? If you can, do! Request that your folks don't buy the cr@ppy foods that will tempt you. Fill the house with fruits and veggies and lo cal dressings. You can eat a lot of fruits and veggies for much fewer calories. Start looking at lables. If something is all fat and sugar, look for something else
If you are not active at all, start slow. If the best you can do it walk to the mailbox, then walk to the mailbox. After a few days walk to the mail box then across the street and back. Then down the block, etc . . . If you try to do too much all at once it is likely that you will get discouraged.
If you can find a buddy to encourage you do so, even if your buddy is already in good shape. you need someoone you can rely on to help you get motivated (these people tend to be difficult to find). If you have a dog, then you do have a motivating buddy. When Fido has to "go" take him for a walk instead of opening the back door.
And this part is very important, WHEN you fall off the wagon (because we all do) DO NOT look at it as a failure, look at it as "I will do better tomorrow." One slip is not a failure and all is certainly not lost. Even thin fit musclebound folks eat cheesecake occassionally.
it is harder to lose weight than to gain, so do not expect to lose 60 pounds in 6 months. Do it healthy, take baby steps and do it right and you will have a mush greater chance of long term success.
On a personal note, I was about 30 pounds overweight when I was a teenager. it wasn't until I got out of my folks house, and went away to college and could chose my own groceries and really have control over what I would and would not eat that I lost the weight. I've kept it off for 15 years so far.
Finally, come here whenever you need a hand!
