Wondering if anyone has heard of or has had any personal experience with the Johnson UpdayDownday Diet, also known as the SIRT1 Lifespan Diet and the The Alternate-Day Diet. Apparently it's been featured in a few magazines, including "Women's Day".
From what I can gather, Dr. Johnson is a New Orleans plastic surgeon who struggled with his own obesity and developed the diet in 2003.
There are no special foods, products or supplements to buy and they don't sell any. However, they do recommend commercially prepared shakes the first two weeks. They do not sell any shakes, so you can purchase whatever shakes are available at the local grocery store.
There's not even a book yet on the diet, although the website indicates that a book is forthcoming.
Basically, you alternate every other day on the diet. On an upday you eat whatever you want until you feel satisfied. On a downday you limit your calories from 20% to 50% of normal. There's a calculator on the site to help you figure it out.
Based on the calculator and my stats (gender, height, weight, age, activity level, weight loss vs maintenance mode), my upday calorie limit is 2,020 and my downday calorie limit is 505.
The whole thing sounds plausible. There is a forum on the official website, but it has very little activity.
You can read about it and how to do it at the official website (link below) or Google Johnson Upday Downday Diet:
The website doesn't sell anything, there's nothing to buy and I'm not affiliated with it in anyway. Hopefully, the link won't be removed as spam. If so, just Google it.
I'd really like to hear if anyone has any personal experience with this diet as I'm seriously considering giving it a try. Perhaps if there's enough interest we can start a Johnson Upday Downday club or challenge.
Any interest?
