I have been fat for something like 22 years, (I am now almost 55), for the most part. Sure, I dieted the weight off , and gained it back with it's new extra pounds. I also had (have) a good life. I do everything a nonobese person does. I did/do not allow being fat to stop me. Dancing, swimming, riding, badminton, hiking, you name it. Being fat always made those things more difficult for me than for my skinny-minny friends, but I actually felt perversely proud of the fact that even though I was well overweight, I could still hold my own in all those activities. Just like my skinny friends playing badminton with a 50 lb pack on their backs. Just try that! I soldiered on. But . . .
Now here comes the big HOWEVER. ..
It cannot go on forever. You cannot deny the weight and its' effects on your body or the toll it takes. You have to work harder and harder to overcome it, and it wears you down, joint by joint.
Most of the pictures posted show young people .. You cannot get back your knees once they are trashed. And, you will find that the thing you love most in the world - riding- will become harder to do, more painful and you will be less able to do it. Of course, age itself plays a part, but I hate to say this, but being fat will make you age harder than those who are not fat for many years of their life. AND, the longer you are fat, the harder it is to take the weight off. The older you get, the harder it is to take the weight off.
Sure, you should most definitely love yourself and immerse yourself in life without self hate or shame. But, try to keep in mind the very far distant future.
Think of it this way; "if it's hard to take off weight now (and it surely is), will it be easier next year? (I assure you it won't). Do I want hard or harder?"
