The Claim

A 6-month web-based weight loss program delivered to Mexican adults with overweight or obesity resulted in significant reductions in body mass index, waist circumference, and body fat percentage, but did not result in significant improvements in systolic blood pressure, fasting glucose, lipid profiles, or most health-related quality of life domains at 3 or 6 months.

Description
1 study reviewed
In plain English

In Mexican adults with overweight or obesity, a 6-month online weight loss program lowered body mass index, waist size, and body fat percentage, but did not change systolic blood pressure, fasting glucose, blood lipids, or most quality of life measures after 3 or 6 months.

See the scientific wording

A 6-month web-based weight loss program delivered to Mexican adults with overweight or obesity resulted in significant reductions in body mass index (BMI), waist circumference, and body fat percentage, but did not significantly improve systolic blood pressure, fasting glucose, lipid profiles, or most health-related quality of life domains at 3 or 6 months.

Why this might work

When people eat fewer calories than they burn, their body breaks down fat stores to use as energy. This makes the body smaller and less fatty, but it doesn't automatically fix blood pressure, blood sugar, or cholesterol levels, or make people feel better in daily life, because those changes need more time or different kinds of signals.

  1. Study: Efficacy of an Online Weight Loss Program for Mexican Adults: Findings From a Randomized Controlled Trial

    An online weight loss program helped Mexican adults lose weight and shrink their waistlines, but didn't improve their blood pressure, blood sugar, or how they felt overall after six months — just like the claim says.
