I will not.
I didn't wait to start my weight loss efforts until the new year. I started two days before Thanksgiving. I'm glad I did. I believe I put the most difficult time of year behind me at the beginning of the journey rather than balloon another 5 or 10 pounds and then start with a "new year's resolution." Anyway, I learned... "do it today" is better than "start next year." I'm down 16 lbs in the last 5 weeks... 19 lbs more... and I'm no longer a "Clyde."
I've been specific about some goals. I have daily goals on caloric intake (2200 cals); exercise (1000 cals); carbohydrates (100 net carbs). I have monthly goals for weight loss (10, 9, 8, 7, 6, 5 = 45 lbs in 6 months.) I've joined a year long running competition (1000 miles in 2013.) I will do at least one century ride by July 31. I'll run a 5K by July 31.
Have you though about it (and written it down) on how you will improve over the next year? I'd love to hear it. Nobody wants to continue living their lives forever with a 30+ BMI.
