Is there any difference between "I am going meat-free" and "I am going meat-less"?
In my opinion, there is not any. I may be wrong.
The meaning of "-less" and "-free" is "without".
There is no difference in as much as they both mean "I will no longer eat meat". However, I find your second sentence unnatural. I would use:
I'm going meat-free.
I'm going to adopt a meatless diet.
Even then, I'd be more likely to use "meat-free diet". If you're only talking about meat, then those are your options. If you're giving up meat, fish, shellfish, gelatine and rennet, then "I'm going vegetarian" would be more normal.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
