The Claim

A caloric restriction of 400 kcal per day for 6 months in obese adults at increased risk of type 2 diabetes results in an average weight loss of 3.3 kg and significant reductions in visceral and total body fat mass.

Source: Potential effects of reduced red meat compared with increased fiber intake on glucose metabolism and liver fat content: a randomized and controlled dietary intervention study.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

Obese adults at increased risk of type 2 diabetes who reduce their daily calorie intake by 400 kcal for six months lose an average of 3.3 kg and experience significant decreases in fat around their organs and throughout their body.

See the scientific wording

Caloric restriction of 400 kcal per day for 6 months results in an average weight loss of 3.3 kg in obese adults at increased risk of type 2 diabetes, accompanied by significant reductions in visceral and total body fat mass.

Why this might work

When a person eats 400 fewer calories each day, their body uses up stored iron, which lowers iron levels in the liver. Less iron in the liver means fewer harmful molecules are made, which lets the liver burn fat more efficiently and stop making new fat. This causes fat to decrease in the liver and throughout the body, leading to weight loss.

  1. Study: Potential effects of reduced red meat compared with increased fiber intake on glucose metabolism and liver fat content: a randomized and controlled dietary intervention study.

    When people who are overweight and at risk for diabetes cut 400 calories a day for six months, they lose about 3.3 kg and reduce fat around their organs and body — no matter what else they eat. The study proves this happens just from eating less.
