In the end, “low-carb” meant about 30 percent carbs and 45 percent fat, while “low-fat” was about 29 percent fat and 48 percent carbs. Despite not being required to cut calories, participants were eating an average of 500 calories less, and what they were eating was high quality. The low-fat group was encouraged to choose whole grains, a variety of beans and lentils, seasonal organic fruit, organic low-fat milk and lean meats. The low-carb group was pointed toward high-quality oils and fats, organic avocados, hard cheeses, nut butters, grass-fed meat and pasture-raised eggs. “Everyone was supposed to have vegetables all day long as much as they could, have a salad every day, and no added sugar and as little refined flour as you could get,” Gardner said.
They designed two diets that were very similar to each other, and unsurprisingly got similar results.

- matt_wulfeck 9y agoAlmost everyone I know (including myself) would not consider a diet that was 45% fat as low carb. The fat should be much higher and the carbs much lower.
- WillPostForFood 9y agoTotally agree - the proposed diets were very middle of the road, non-controversial, and similar.

This could also be simply attributed to being watched. That to me is a huge confounding factor that needs to be carefully isolated in all diet studies. The huge success of personal fitness trackers suggests people tend to have healthier lifestyles when they measure their actions, even if it's for their own personal record (let alone for sharing on social media or being studied).
- AstralStorm 9y agoThis is why cross study design is better. In both cases the vigilance is applied nullifying it as a factor. The trouble is that diets take very long to apply so a cross design study would take many years.
