Food
What the evidence says about what we eat: foods, diets, nutrients, and the eating habits of different places.
Same weight lost, keto cut more liver fat
Fifty-five adults with obesity, prediabetes and fatty liver were given every meal they ate until each had lost about a tenth of their body weight. Insulin sensitivity in muscle rose by about half on all three diets, with nothing to choose between them. In the liver the diets separated: fat inside the liver fell 67 percent on the ketogenic diet against 45 percent on the Mediterranean and very low fat diets, and prediabetes resolved in 50 percent of the ketogenic group against 29 and 7 percent. Forty-two people finished, 14 per group, and every outcome measured was a marker rather than an illness.
Fasting and plain calorie cutting come out almost level
A review of 99 randomised trials found most fasting schedules matched ordinary daily calorie restriction. One pattern edged ahead, by about a kilogram.
