A reader sent a link this morning to an interesting study of alternate day fasting for obese adults.
Even though the study participants ate whatever they wanted on their non-fasting days, they lost an average of 5.6 kilograms (about 12 pounds) after eight weeks, Dr. Krista A. Varady of the University of Illinois at Chicago and her colleagues found. […]
"People lost anywhere from about 7 pounds to about 30 pounds and that was in a very short amount of time," Varady said. And, she added, the program was pretty easy for the study participants to follow.
So, what did they do? Apparently oblivious to the underlying paleo principle at work, they’ve made the shocking discovery that if you simulate unavailability of food that people begin to revert to a normal [hunting] weight. News flash: wild animals including wild humans don’t have pantries and refrigertors or local supermarkets & restaurants. They’ve got to hunt, gather and prepare their food, and they’ve also got to think and plan in case migration or other measures will be required for future food. That all adds up, and it’s why HGs are typically lean.
To test alternate-day fasting in obese adults, Varady and her colleagues had 12 obese women and 4 obese men begin by eating normally for a two-week control period. Then, for eight weeks, they ate just 25 percent of the calories they needed to maintain their weight, between noon and 2 p.m., every other day.
So, they ate with no restrictions every over day, and on the "fasting" days they ate 25% baseline caloric intake in a 2-hr feeding window. So, not even a true fast in the way we typically do but still quite impressive in terms of results.
I’m fasting today until dinner and got in a pretty intense workout a couple of hours ago. This was my last meal, roasted chicken and a simple sauce. I had no chicken stock, but I do keep some of the Trader Joe’s paste packets around for just such contingencies. No unpronounceable ingredients. So, two chicken and one vegetable in 1 1/2 cups of water, to a boil; add about 1/2 tsp of tarragon, 1/2 tsp of bay leaves, and a light shake of paprika. Then, about 1/3 cube of sweet organic butter. Reduce, then just a 4-finger dash of potato flour to thicken, which is no more than about 5g of carb.
No veggies. Instead, I had a few walnuts and then 5 frozen cherries in some full fat yogurt.
