Is there any support for eating addiction?

I got excellent support through my GP.
Referral to a dietitian, and ongoing weekly meetings to reduce my eating, targeted at reducing my obesity.
I was prescribed a meter and test strips, so we could work together to create a profile of foods that didn't cause me spikes, and together we reduced my eating dramatically.
I also got referred to an NHS gym for a period, which started me on the way to exercising regularly.
The courses are there, but you do have to ask for them initially.
