You know, I think that if I had a nutritionist cooking for me, and a television camera up my rear end 24 hours a day, and a personal trainer forcing me to work out 5 hours a day...that yes, I would lose weight faster than I am right now.
But, is that going to be sustainable, when I go back home to regular life? Probably not.
Someone losing 100 pounds in a year's time IS fast weight loss. VERY fast, actually.
A healthy rate of weight loss for most people, is in the 1-2 pounds a week range. This is with a healthy, reduced calorie diet, and regular exercise. What you will find, is that when you are at your higher weight of over 200 pounds...that you will see larger losses at first-you might lose 2, 3, 4, or even more pounds in the first week. After that, you might see 2 or 3 pounds a week for a few weeks. After that, however, it will slow down a bit. When you get very close to goal...you might only be losing 1/2 a pound a week.
My advice, is don't compare yourself to a reality show...especially one where the contestants are REMOVED from reality. (Home, family, jobs, kids, etc.) Those people have no responsibilties at the time, other than losing weight.
For those of us with kids, jobs, and households to take care of...we have to do what fits into our lifestyles. If that means you have time on Saturday for a 1 hour workout...but Wednesday night is too hectic and you only have 20 minutes for exercise...then it is what it is, and you move on. It doesn't mean that you are not putting your all into it...but that you have to strive a balance between the demands of life.
Also, enjoy the ride. If you decide that you want to lose 50, 70, or 100 pounds...it doesn't mean that you are not going to reap the rewards of weight loss until you hit that number. Trust me, there are lots of rewards along the way...
~When you realize after losing 30 pounds, that you have to go buy all new pants
~When someone who hasn't seen you in a couple of months notices that you have lost some weight
~When you go from plus size clothes, to misses size clothes
~When you realize that the workout video or class that you couldn't do through to the end at first, is now easier and you can finish every last rep.
There are LOTS of wonderful things along the way...enjoy the ride, instead of just concentrating on the end number.
If you started out at say, 220 pounds...then you should feel happy, and proud, when you reach 210, 200, 190, 180, etc.-not just when you reach goal.
Is it possible, however, to lose 100 pounds in 3 months? Not really. That would mean losing more than 1 pound a DAY, every day, for 3 months.
