I've been a bit stuck in my weight lately and yesterday I had a "Gaaaahhh!" type of day, which resulted in my allowing myself to eat not only half of a cheese pizza (frozen type), but also a pint of Oikos Chocolate Frozen Greek Yogurt. (Which is AH-mazing.)
Were you eating enough before? Your body will store fat if it doesn't get enough to eat, causing you not able to lose weight. Then you eat and your body goes into crazy mode.
There are things the human body does that shouldn't even be questioned. No matter how hard we try we cannot control out body, we just can't. We can steer it in the right direction, we can be consistent about how we care for it but at the end of the day we simply have no control what happens. My good friend got cancer and died - there was no family history and she was as healthy as they come. Ok that's a little depressing I know but it's been on my mind a lot, losing her is hard enough, but the why and the how is unexplainable. You can't control everything. Especially with calorie counting.
