This week on Fat Science we answer your questions in another, always-popular mailbag episode. Join Mark Wright, Andrea Taylor, and Dr. Emily Cooper and learn why some people don’t respond to GLP-1 medications, get the latest on new, oral weight-loss drugs, and explore the science behind elevated liver enzymes.

Dr. Cooper offers practical insights backed by metabolic research. She also addresses gluten-free diets, flavored seltzers, craving pathways in the brain, chronic pain management, and the importance of consistent eating patterns for metabolic health.

Key Takeaways:

• About 20% of people may not respond to GLP-1s due to genetic and metabolic differences; deeper lab and genetic testing may be needed to uncover root causes.
• New oral GLP-1 options like Orforglipron are on the horizon, promising greater convenience and accessibility.
• Transient increases in liver enzymes can occur with rapid weight changes; regular monitoring and medical guidance are important.
• The POMC pathway in the brain plays a crucial role in cravings and metabolism—medications like Contrave can help by targeting this pathway.
• Flavored seltzers are generally fine, but watch for BPA-lined cans; gluten-free isn’t always healthier unless medically necessary.
• Chronic pain medications often impact metabolism—exploring underlying metabolic causes and non-GABA, non-opioid alternatives with providers is key.
• Consistent, “patterned” eating supports metabolic stability and brain function.

Personal Stories & Practical Advice:

• Andrea shares how tweaking her medication “cocktail” and eating patterns improved her results.
• Dr. Cooper and Mark discuss real-life snack strategies for fueling brain power and avoiding metabolic pitfalls.
