I dont think the time matters when youre generally eating through the day. What can be bad for you is going all day without eating and then eating a days worth of food in the evening. I dont actually know if this matters to weight loss, but it can cause problems with blood sugars and insulin resistence.
For a lot of people the evening is a time for sitting in front of the telly, which generally in our house leads to crisps, sweets etc. I think not eating in the evening helps people get out of that sort of habit. But if your hungry after dark, eat!! Ots not like you will turn into a gremlin!
