I don't want to do it for me....Why????

Show yourself instead of "him" that:
1. You can do really hard things, and losing weight was just one of the really hard things you decided to do.
2. You are one of the lucky ones. You can make what is hard appear easy to others. You make others jealous of what you can accomplish. And you know this because you were once on the other side.
3. You've always deserved more, but now you know when you expect more you have the power to actually get more out of life.

I do hope you learn not to rely on men for your self-worth. Men don't deserve that much power over who you are and how you feel.

What's difficult? You eat less than you burn and be totally honest with yourself. The weight comes off. That motivates you to carry on. Eventually people notice. That motivates you to carry on. And on. And on. You don't even have to exercise, the calories in versus calories out equation still works. Exercise just means you can eat more and you're making yourself more healthy into the bargain.

It really is that easy. Instead of thinking how hard it is, start getting involved in the mechanics of it and see, actually, how easy it is. Let your calorie allowance drive what you eat, for example, feel like a donut? 450 calories, are you joking? Have a banana instead, only 90 or so calories. Walk up a flight of stairs instead of using the lift or escalator.

This should not be about showing anyone how clever you are, this should be about being fed up of being fat and unhealthy.

You're right it's not difficult. Recently since I gained all my weight back, I have been saying how I wished I could just lose the weight, but it's so hard. Then one day, I had the realization that no it's not hard. You either do it or you don't. You either stuff your face with a whole pizza (like I can do), eat a piece or 2 in moderation and still enjoy it, or you don't eat it. Really, unless you are facing a health issue, weight loss is not as hard as we all like to make it out to be. It comes down to determination-how bad do you want it and the simple thought of eat less move more. I am certainly not belittling anyone's efforts-I weigh 300 lbs-clearly I don't have it down, but looking at it from a new perspective is helping me.

I'll admit to that in the beginning, a piece of my motivation was to show someone off. When I told my brother that I planned on rejoining WW, he rolled his eyes and said "here we go again". I was hurt and pissed off by that. He had a point, I had tried many diets and failed but it still sucked that he didn't have confidence in me or couldn't put the past behind and just be encouraging. But I turned that hurt and mad into motivation and it got me through a few points in the first six months or so when I'd normally have slacked off or even given up.

As someone else said, your motivations and methods will change as you go along anyway. If this works for you now, who's to argue with that?! Maybe six months from now when you're feeling more confident, you'll realize it's all about you and his opinion doesn't mean crap anymore.

I wouldn't say your way of thinking is wrong, but keep this in mind - if he's still not impressed when you lose the weight, are you going to think this was for nothing? Or, are you going to flip him off and realize that your well-being is more important than his opinion? I'm just saying that people don't want to be wrong, and you don't want to base this effort on something that may never happen (i.e. him being impressed).

This. I've seen people just quit because they lost a lot of weight and people around them refused to notice or compliment them. If you do it because you're expecting someone to react favorably, you might want to look for other reasons.

I agree with all the aforementioned here. Sure it may work for right now, but you may be setting yourself up for a bigger let down than you can bargain for. I remember watching a weightloss show on MTV and the girl did it to impress some guy or hope he'd like her. Not only was he not impressed, but he told her to go back and lose more. Dig deep within yourself and find that YOU are worth this hard work, this trouble, and this sacrifice. It shouldn't be for some guy, some dress, some class reunion, some vacation, or some other event; but for you, your health, your betterness, and your increasing your chances of living a healthier life.
