. I hope you feel better soon. Sounds awful and I hope it doesn't interrupt your holiday.
Julie. I aim for 2,000 calories, and usually fall between 1,900 and 2,100. When I started my routine, and started eating as clean as I could, I also found it hard to get all my calories. I did it, but I had to work at it. For me I think it was because I was so used to starving all day and eating all night that when I started eating breakfast, mid-morning snack, lunch, mid-afternoon snack, I was feeling completely full all day. That's changed for me, I think in direct correlation to how much I work out. I think my body wants all those calories, and I find myself hungry by the time I get to meal times, but satisfied with what I eat. I think this is a good sign because I'm pretty sure my metabolism is working a little more normally, and it's good to feel hungry when I get to my food.
I'm sure everyone is different, and your past eating habits, lifestyle, and body chemistry will affect things. But that's my perspective.
