I agree with the comments above, those kind of comments are pure toxic b.s

I would tell them where to jump and not even give them any more thought, you don't that kind of negativity in your life.

Also...1000 calories is not very much, I hope you are getting lots of nutrient rich food into your diet while the calorie count is so low, I would hate to see you fall unhealthy on account of others rude and idiotic behavior.

Take care
