The Claim

In obese adults undergoing a two-month weight loss intervention, a very-low-calorie ketogenic diet produces a mean weight loss of 9.7 kg, which is significantly greater than the 1.67 kg mean weight loss produced by a standard low-calorie diet.

Source: MRI estimated changes in visceral adipose tissue and liver fat fraction in patients with obesity during a very low-calorie-ketogenic diet compared to a standard low-calorie diet.

In plain English

Obese adults who followed a very-low-calorie ketogenic diet for two months lost an average of 9.7 kilograms, while those who followed a standard low-calorie diet lost an average of 1.67 kilograms.

See the scientific wording

In obese adults undergoing a two-month weight loss intervention, a very-low-calorie ketogenic diet resulted in a mean weight loss of 9.7 kg, significantly greater than the 1.67 kg loss observed with a standard low-calorie diet, indicating a substantial difference in short-term efficacy for weight reduction.

Why this might work

When the body runs out of sugar for energy, it switches to burning fat, which produces ketones. These ketones reduce hunger signals and cause the body to break down stored fat for fuel, leading to rapid weight loss.

1 study
  1. Study: MRI estimated changes in visceral adipose tissue and liver fat fraction in patients with obesity during a very low-calorie-ketogenic diet compared to a standard low-calorie diet.

    In this study, obese people who ate a very low-calorie keto diet lost almost 10 pounds in two months, while those on a regular low-calorie diet lost less than 2 pounds — showing the keto diet worked much better for quick weight loss.
