New year's resolution is tough to keep. It's a promise that never fulfilled. Never wait for a new week, month, or year to do something important. Just do it the same time or the next day. I was losing weight one ounce at a time until I put on an extra 20 lbs over the Christmas holiday, and the new year is not over yet. Leave the weight loss for the women.
The best way for significant weight loss is to take a big dump and weigh yourself after. You will be surprised to drop 10 lbs in one bathroom visit.
