The Science

In order to do this in a scientific way we’re working with nutritionists and statisticians from UC Berkeley.

During the sign-up process, you’ll have the option to be given a diet that we’ve selected for you. The scientific process calls this part of the experiment randomization. The intent is to remove bias—perhaps fans of the 4-Hour Body diet are inherently more motivated than fans of the USDA.

I was skeptical about people accepting our diet recommendation for them, but early joiners have voted 3 to 4 to participate in the randomized trial. (There will also be an opt-out of the randomization step, for those 1 in 4 people who want complete control.)

After we get you going on your new diet, we’ll measure via Lift and occasional surveys:

Are some diets easier than others? The scientific term is adherence.

Weight change. Of course, this is a goal for many of us.

Happiness via mood, energy and enjoyment.

Demographic factors.

Success tips for each diet. In our single-diet trial of the 4-Hour Body last year, we were able to verify the effects of simple meal planning, eggs for breakfast, cold showers, cheat days, and alcohol consumption.

Of course, we’re going to be careful to respect your privacy. All data will be aggregated and anonymized. That’s really important to us.
