London, Tokyo, and Topeka – across the globe, this past week was the worst week for our diets. In no single week does our planet gain more weight.
Here’s the good news: That all ended yesterday – on January 3rd. That’s when our collective worldly wait peaks and starts to decline. We know this because we studied the up and down weigh-ins of 10,000 people around the world that had bought wireless scales (focusing mainly on Americans, Germans, and Japanese) and we published it in New England Journal of Medicine.
It doesn’t matter if you live in Tokyo or Topeka, you start to increasingly gain weight on December 10, and it keeps climbing until January 3rd, After the 3rd, it slowly started to drop for these people. Especially for those who weighed themselves often.
Besides Tuesday being the last heaviest day of this holiday season, the study also has another silver lining. People who weighed themselves at least four times a week, lost half of their holiday weight by the end of January. If you don’t hide from the bad news, it won’t be bad news for very long.
These discoveries are important because they show that the more weight you gain during the holidays, the longer it takes to lose it. Instead of beating yourself up for not shedding holiday weight this year, we would be better off making a resolution to keep weight gain down during the next holiday season,
