Well it certainly wouldn't be a bad idea to see him - it will cost you nothing and could well get some advice to help you along to you goal?
I also believe that if you starve your body especially if it is used to having more food then your metabolism will slow down and protect itself, hence, you stop losing weight.
When I first started on this journey early October I went about it all wrong and more or less went on a strict low fat diet - I gained, yes... gained weight! Half a kilo to be exact! Once I joined this forum and received some valuable advice - I ate more - and started losing weight. In fact, I eat more now than I did before, just healthier eating. With a few things that perhaps I shouldn't eat - but am still losing the weight. I am currently working on the 80/20 theory - I stick to a low fat diet 80% of the time and have say some chocolate, or a bacon sandwich once a week.
I have just realised that I have rambled on a bit - might have to get a publisher if I keep on
But IMHO I would go and see him, you could well come away armed with something very important to you.
