NCT05139420

Brief Summary

This study aims at identifying the neurohormonal biomarkers that characterize individuals at risk of greater metabolic adaptation to weight loss, a disproportionate decline in resting metabolic rate during and after weight loss.

Outcome Measures

Primary Outcomes (1)

  • change in measured and predicted resting metabolic rate during and after weight loss

    resting metabolic rate will be measured by indirect calorimetry every 2 months for 6 months, then every 6 months for an additional 12 month. Predicted resting metabolic rate will be calculated with a mathematical formula at the same time points

    18 months

Secondary Outcomes (7)

  • change in circulating leptin during and after weight loss

    18 months

  • change in circulating thyroid hormones during and after weight loss

    18 months

  • change in circulating GLP-1 during and after weight loss

    18 months

  • change in circulating PYY during and after weight loss

    18 months

  • change in circulating AgRP during and after weight loss

    18 months

  • +2 more secondary outcomes

Study Arms (1)

lifestyle intervention

EXPERIMENTAL

Participants will be enrolled in a weight loss program based on lifestyle changes. They will be given a 6-month subscription to a calorie-reduced meal replacement program that also offers lifestyle coaching.

Other: lifestyle intervention with meal replacement program

Interventions

participants will be enrolled in a medical weight loss program and will be given a 6 month subscription to a calorie-reduced meal replacement program, in addition to lifestyle advice.
