The Claim

A 12-week hypocaloric meal replacement program in obese adults is associated with significant reductions in body weight, body mass index, and waist circumference.

Source: Preservation of muscle mass assessed by ultrasound during a meal replacement-based hypocaloric intervention in obese individuals: a real-world clinical trial.

In plain English

Obese adults who followed a 12-week hypocaloric meal replacement program experienced measurable decreases in body weight, body mass index, and waist circumference.

See the scientific wording

In obese adults, a 12-week hypocaloric meal replacement program was associated with significant reductions in body weight, body mass index, and waist circumference, indicating effective weight loss.

Why this might work

When the body takes in fewer calories than it burns, it starts breaking down stored fat for energy. This causes fat cells to shrink, which reduces overall body weight, waist size, and body mass index.

  1. Study: Preservation of muscle mass assessed by ultrasound during a meal replacement-based hypocaloric intervention in obese individuals: a real-world clinical trial.

    This study found that when older adults with obesity replaced one meal a day with a special shake for 12 weeks, they lost weight, shrank their waistlines, and lowered their BMI — just like the claim says. Their muscles even got stronger, which is a bonus.
