Wow, Fletch, thanks for putting this out there. I can totally relate...the vacation, the cold, the not wanting to get on the scale. You are really holding yourself accountable and I really admire that!
I've had some setbacks too, recently, from vacation and a couple days sick; missed workouts, comfort foods, etc., etc. I went back onto plan and the 5 vacation pounds came right off. I am back on plan from being sick last weekend (how could two days produce 6 pounds; the math doesn't add up
) and it's not really coming off now, so I needed to hear your excuses and your no BS attitude toward getting back.
Can you do something less intense, like a 20 minute walk, just to remiind your body it can move and respond to exercise? Also, tell yourself your body can heal itself quicker if you put heathy food into it. Fruit sorbets, although they do have sugar, are better options than ice cream and shakes, or you could make a fruit smoothie and even throw some protein powder in there. Staying away from dairy might be a good idea if you're congested, though...so I'm thinking lots of frozen fruit in a blender.
I'm reminding myself that I did this before and I can do it again, and so can you! You know what you need to do and once you are a few days back into it, you will feel awesome and successful. The most important thing is to stop with the excuses, which you did. Just let your old, good habits take over, be diligent with your food log, and keep posting and/or journaling. You'll get there.
