Stubborn weight gain with no diet change — what is the first oMeds step?

Short answer

Weight gain is routed by metabolic and hormonal context. GLP-1 (semaglutide/tirzepatide) for BMI-eligible candidates with insulin resistance signals; TRT or BHRT when hormone biomarkers match; Lipo-B for adjunct metabolic support.

Full answer

Weight gain rarely has a single driver. Provider review reads fasting insulin, A1C, lipids, total/free testosterone, estradiol, TSH, and cortisol context before initiating any pathway. BMI-eligible candidates with insulin resistance or weight-related comorbidity are routed to GLP-1 pathways (semaglutide or tirzepatide); titration and side-effect review happen on the recalibration cadence. Men with confirmed low testosterone and central adiposity are evaluated for Testosterone Optimization in parallel. Women in perimenopause with matching biomarkers are evaluated for BHRT. Lipo-B is an adjunct, never a primary pathway. Every plan is synchronous-video reviewed.

Unexplained weight gain?
Unexplained weight gain commonly reflects thyroid dysfunction, insulin resistance, hormonal shifts (perimenopause, low testosterone), sleep loss, medications, or cortisol dysregulation.
Can high insulin cause weight gain?
Yes — chronically elevated insulin promotes fat storage, suppresses lipolysis, and drives hunger and cravings. It is both a cause and a consequence of weight gain, which is why the two reinforce each other and why early intervention matters.
Can thyroid cause weight gain?
Yes — but typically modestly. Frank hypothyroidism slows resting metabolic rate and causes fluid retention, producing weight gain on the order of 5–15 pounds. Larger gains are rarely fully explained by thyroid alone and require the full metabolic workup.
