In plain English

Obese adults following a conventional diet plan do not lose significant weight in the short term or long term over three years.

See the scientific wording

In obese adults participating in weight reduction programs, a conventional diet plan is associated with no significant short-term or long-term weight loss over a 3-year period, suggesting it may be ineffective for sustained weight management in this population.

Why this might work

When a person eats less, the body slows down its energy use and makes the person feel hungrier, so weight loss stops even if eating stays low.

  1. Study: Short-Term and Long-Term Effects of Weight Reduction Programs Offered at the Guthrie Clinic

    The study found that when obese people tried a standard diet without extra help, they didn’t lose any weight — not even at first, and not even after three years. So yes, the usual diet plan didn’t work for long-term weight loss.
