Weight Management

Evidence-based approaches to sustainable weight loss

The compounds with the strongest clinical evidence for weight management, including GLP-1 receptor agonists and metabolic support agents. Educational summary of published trial data.

Protocol Map

Compounds organized by evidence tier. Foundation compounds have the strongest clinical support. Emerging compounds show promise but lack robust human data.

Foundation

SemaglutidePeer Reviewed

GLP-1 receptor agonist for weight management

FDA-approved for chronic weight management. The STEP clinical trial program demonstrated average weight loss of 15-17% of body weight over 68 weeks in non-diabetic adults. The most extensively studied GLP-1 RA for obesity.

Literature dosing: 0.25-2.4 mg weekly SC -- STEP trial titration schedule

TirzepatidePeer Reviewed

Dual GIP/GLP-1 receptor agonist

FDA-approved dual incretin agonist. The SURMOUNT-1 trial showed up to 22.5% body weight reduction at the highest dose. Acts on both GIP and GLP-1 receptors for enhanced metabolic effect.

Literature dosing: 2.5-15 mg weekly SC -- SURMOUNT trial titration schedule

Commonly Added

MetforminPeer Reviewed

Insulin sensitization and metabolic support

A biguanide with decades of safety data. Often used alongside GLP-1 RAs for additive insulin sensitization. May also offer modest independent weight benefit via AMPK activation.

Vitamin B12Peer Reviewed

Nutritional support during GLP-1 therapy

B12 deficiency is commonly observed during both metformin use and rapid weight loss. Monitoring and supplementation help prevent neurological symptoms and fatigue.

Emerging

SermorelinClinical Data

GH-mediated body composition improvement

A GHRH analog that stimulates endogenous GH release. Some clinical data suggest favorable shifts in body composition (reduced fat mass, preserved lean mass), though evidence is less robust than for GLP-1 RAs.

BPC-157Emerging Research

GI support during GLP-1 therapy

Some practitioners report using BPC-157 to support GI tolerance during GLP-1 RA titration, based on its gastric origin and preclinical gut-healing data. Human evidence for this specific application is limited.

Recommended Monitoring

Lab work and clinical assessments commonly recommended when pursuing this goal. Your provider will determine the appropriate testing schedule for your situation.

Monitoring recommendations based on published clinical guidelines and expert consensus
TestFrequencyPurpose
Comprehensive Metabolic PanelBaseline, 3 months, then every 6 monthsMonitor liver function, kidney function, and electrolytes
HbA1cBaseline, 3 months, then every 6 monthsTrack glycemic control and insulin resistance improvement
Fasting InsulinBaseline, then every 6 monthsAssess insulin resistance independently of glucose
Thyroid Panel (TSH, Free T4)Baseline, then annuallyGLP-1 RAs carry a precautionary thyroid warning; monitor for changes
Lipid PanelBaseline, then every 6 monthsTrack cardiovascular risk factor improvement with weight loss
CBCBaseline, then every 6 monthsGeneral health screening, monitor for nutritional deficiencies
Vitamin B12Baseline, then every 6 months if on metforminScreen for depletion common with metformin and caloric restriction

Lifestyle Foundations

Caloric deficit through whole-food nutrition is the foundation of any weight management approach. GLP-1 RAs reduce appetite but do not replace the need for dietary quality. Protein intake of at least 0.7 g per pound of body weight helps preserve lean mass during weight loss. Resistance training 2-4 times per week counteracts the muscle loss that accompanies rapid fat loss. Adequate hydration (at minimum 64 oz daily) supports the GI tolerability of GLP-1 therapy.
