I've made a massive determined effort to really up my veg intake and in general make sure all my meals are bursting with nutrients. Prior to that, I was eating fairly well overall, but due to tiredness I'd slipped into dinner being something like a pile of toast three days a week. Now four weeks into eating loads of veggies and proper dinner everyday, I was hoping to have more energy and just feel a bit better but I don't really feel different at all 
I have autoimmune illnesses so it's probably just that. Am I right to think if I wasn't ill I'd have experienced some benefits by now? Or AIBU can it take months to feel more energy from a diet change?
