Originally, GLP-1s like Zepbound were for diabetes and weight loss. A new study just found Zepbound to help with sleep apnea. I break down how effective it is here: open.substack.com/pub/katu300/p/…

GLP-1s are incredibly popular. In this Substack article, I break down research comparing GLP-1s and weight loss surgery. It’s an interesting listen during your morning commute: open.substack.com/pub/katu300/p/…

Hello! Research papers are hard to understand even for science people. My Substack “Science Decoded” breaks down research so that anyone can understand it.

fact snack: The hypothalamus is like your body's thermostat but for energy. It constantly monitors how much energy you have vs. need and adjusts hunger accordingly.

7/ Full breakdown: What the researchers found, how inflammation disrupts appetite control, what it means for metabolic health, and what we still don't know. Read here:katu300.substack.com/p/ultra-proces…

6/ Important caveat: This is CORRELATION, not causation. We can't definitively say UPFs cause these changes without controlled experiments

Your brain’s appetite center is the size of an almond. Ultra-processed foods could be messing with it. Here is what 30,000 brain MRIs revealed.

6/ It’s complicated. I break down the actual trial data, what the safety concerns mean, and what happens next for PTSD research: open.substack.com/pub/katu300/p/…

5/ The FDA questioned the study design. They were worried that the therapists may have downplayed the participants’ symptoms or experiences, making the results seem more positive than they really are.
