If I start my day late and have breakfast late, then yes, I find it difficult. I am currently full after only 800 calories so far- we all have days like that. Then, there are days with 2000 calories where I am RAVENOUS!
Ultimately, I've heard it's never a good idea to go below 1200 for a day since your body will think it's starving, and your metabolism will slow. Maybe try to slowly work your way up, so you don't negate your hard work? Like, have 900 tomorrow with a treat or something? I do believe you that you are full...maybe something light like a yogurt or some hummus?
I am still relatively new on this though. What does everyone else think?
