Healthy Diet and Exercise!!

it makes everything better, your attitude, self esteem, sex, etc.
But, don't think the ladies much give a damn ( 5'8 215 ) as long as u bring the envelope!!

Once because I was to heavy for the table she had and once because I seen a new lady that didn't know what it take to be a provider. I doubt you will have any issues, because overweight guys are a norm in the hobby.

At least they will most certainly put on that smile and give you the illusion that they are very happy to see you.  Where they will NOT be happy is if you are not clean (freshly showered), not on time and not respectful.

And most importantly...bring the correct donation.  Without that they will be VERY VERY unhappy!

Outside of those little issues...they will love to meet with you.  

Now as far as your own self-esteem issues...go to the gym, walk, run, exercise of any type and work on achieving your own goals.  Why not set up an achievable goal...say losing 20 pounds and reward is a young hottie

As everyone says you will be far from the heaviest guy most providers see. As for your own esteem and health you can work on losing some weight but don't let that stop you from seeing the ladies. They are not looking for a boyfriend, just a clean and respectful client.

...is to get naked with many different beautiful women who don't judge you (not overtly at least). For me, hobbying actually motivated me to eat healthier, sleep earlier and more regularly, and be more active. But what worked for me might not work for you, as it depends a lot on how your mind works.

In my experience, the only weight she's concerned about is the weight of the envelope you give her.  I'm sure they get many guys who weigh a lot more than you.  Relax and enjoy.
