Gina, I would just plunge right in. There will always be another "food" holiday right around the corner, so don't push off starting the diet until there's not one on the horizon. I started just before Christmas the first time. I'm not going to lie: it was tough making it through Christmas and New Years. But, it's something I was determined to accomplish.
And, for everyone who gets discouraged: I've been completely on plan for weeks, but when I jumped on the scale this morning, I was UP 5 POUNDS. I worked really hard in the yard yesterday digging out a brick patio and stacking the bricks. So, I know my muscles are retaining major water. If the same thing happens, know that it's water weight and/or muscle gain. In the long run, it's not a problem in the least. It's not even a setback. It's just the way our bodies operate.
Have a FANTASTIC, ON-PLAN week. We deserve it!
