why do some ppl drop weight so easy?

I don't believe there is a good answer for that question.

Metabolism! Everyone's is different.

I would say metabolism. Some people just naturally burn fat faster then others. Me and my husband are the perfect example. He can eat whatever he wants and as much of it and seems never to gain ANY weight, but me, if I ate 1/2 of he did I would gain pounds fast! I am so jealous of him!!

Don't loose heart, it sounds like you are doing GREAT!! I am just NOW starting to get serious about my weight loss and with my snail type metabolism, I've got a long road ahead of me...

If you'd like to burn fat faster maybe try increasing your cardio? Are you calorie counting? Best of luck to you!!

Whenever I lose a significant amount of weight its always done in a relatively short period of time--I.E. months, not years. Its because of my all or nothing mentality--I can't just cut back a little. I have to either cut WAAAYYYY back and severely restrict myself every single day compared to my previous life--or else just keep at things the way I was (eat whatever I want). I'm like that with everything in life--call it an addictive personality I guess? I have to either be addicted to eating or starving. I think thats prob what the difference is in some people.

I say that the upside to you losing the weight more slowly is that you are making positive lifestyle changes that you can obviously stick with and her losing the weight so fast puts her at risk for gaining back the weight as quickly as she lost it! Don't give up! YOU have the right idea. Patience is a virtue right??!!

Thanks guys! Its good to get some encouragement! I know I probably need to increase my weight lifting. I have been afraid to, I dont want to get a bulky.

Building up bulk is actually very very difficult for us women, as it requires a good amount of testosterone! Don't worry about it and give it a try. If you do turn out to be an exception and start putting on some bulk, you can always cut back. It WILL reduce the bulk.

Woman don't get bulky! You would have to lift some heavy weight to bulk up. Besides, muscles look great on gals! Here's a good article! Hit those weights and you are guaranteed to burn more calories.

Metabolism as someone mentioned above is definitely part of it. Also, some people are better at going cold turkey then others. For some of us it's a long term struggle, where we find it difficult to stick to eating healthy consistently and so it takes us much longer. Add a slow metabolism to a weak will and the struggle increases. I'm not trying to suggest that you have a weak will or anything. I guess I'm just saying that the time and effort it takes to lose weight varies for everyone. It's not just a physical struggle but a mental one as well. Your co-worker may have been able to stick to eating healthy entirely without any drawbacks and while it is frustrating that other people don't seem to have to struggle as much, it's important to remember that focusing and comparing yourself to others, even in terms of how long it takes other people to lose weight, is not going to help you. I always try to make myself feel better by thinking that the harder you struggle for something, each goal you achieve on the way will matter that much more and you'll get alot more out of it then what you had originally aimed for. I know it's not immediate comfort and I'm not sure it even makes much sense lol but that's the best I could come up with. Don't get discouraged. Keep going and goodluck!

I think you already gave the answer. She dieted and you changed to a healthy lifestyle. You lost fat and built lean muscle which gives you a much better chance of keeping it off.

Bet you look better than her in a bikini though:laugh:

I would say it's metabolism and this:

I've always figured that people exactly like her (heavy fast food and soda consumption) have bodies that just simply wanted out of their eating style. Their bodies go, "WHOA, no more fries?! Finally!!" resulting in drastic weightloss.

If someone was to hit the drive thru 4+ times a month and suddenly give it up then they may drop a lot of weight quickly.
When I started watching my portions I lost about 5 lbs in a week, but I still ate junk. Now that I'm watching not only what I eat but how much of it I've lost more (and exercise).
