I think when you have a lot to lose it's easy to get in the mind set, that "this is what I MUST do".
We're taught that if we lower calories, we'll lose weight.
Often times, what we don't hear (whether because we don't have the information, or we just don't want to hear) is that too low of calories and our body just stops burning them efficiently.
While losing weight I have learned that regardless of how QUICKLY I would like this weight to come off, if I don't do it in a healthy and reasonable manner, it will just come back and there is NO way, I'm ever going to go through THIS again
Your heart is a muscle Wimic - think about what happens if calories are too low and instead of fat, you're losing muscle.
Trust me, I have *walked* in your shoes - I've looked all too closely at the underbelly of 260 pounds. It is overwhelming.
Sometimes we think "This isn't possible" other times we think "Extreme positions call for extreme measures".
Please consider looking at upping your calories, check out or and see what they suggest as a range.
