About this trial

The GRAMS study objectives are to assess the musculoskeletal changes that occur after weight loss using GLP-1 based therapy. A lifestyle intervention with diet and exercise is included to assess any mitigating effects are provided, versus a control group with regular exercise and diet.

Trial outcomes

Primary outcomes

1

Changes in fat free mass (FFM) using DXA imaging. FFM equals all body composition that is not fat mass. This includes bone, skeletal muscle, organs, water and all connective tissues. The unit of measurement is in kilograms (kg) at baseline, 3 and 6 mo.

DXA (Dual energy Xray absorptiometry)

Time frame
Baseline and time 3, and 6 months.

Secondary outcomes

1

MRI (thigh) without contrast

To assess for muscle quality (% of skeletal muscle to intermuscular fat)

Time frame
Month 1 (baseline), month 3, month 6 (final visit)
2

Osteocalcin

Blood draw, metabolism biomarker

Time frame
Month 1 (baseline), month 3, month 6 (final visit)
3

Irisin

Blood draw, bone health biomarker

Time frame
Month 1 (baseline), month 3, month 6 (final visit)
4

Procollagen 1 N-terminal peptide (P1NP)

Blood draw, bone health biomarker

Time frame
Month 1 (baseline), month 3, and month 6 (final visit)
