if you just started a GLP-1, you probably have a lot of questions. this post is for my patients who are on these medications and for folks who want to learn more about them and how to maximize the use of them.

what is a GLP-1? how does it work?

GLP-1s are peptide hormones that tell your brain that you are satisfied. they affect how sugar and food are handled by your body, by changing the amount and rate at which insulin is released by your pancreas.

ultimately, these medicines slow gastric transit (the rate at which food passes through your stomach, into your intestines, and out of your body). because food stays in your stomach longer, a common side effect is nausea, vomiting, constipation, and abdominal pain. this particularly happens if you keep trying to eat the amounts of food you did before you started the medicine, or if you go to a higher dose too quickly.

I heard that compounding pharmacies aren't safe.

this depends on which compounding pharmacy you are using, and whether or not the pharmacy sends their medicines for third-party testing to ensure their products contain the type and dose that they claim.

it's important to ask the pharmacy explicitly for information about this before deciding to order medicine.

body roundness index
dear reader, there’s a new metric on the block: body roundness index. i’m in favor, because even though it’s imperfect, it’s better than BMI. body mass index (BMI), which is a measure the ratio of your weight to height, does NOT take into account your muscle mass or where you’re

“how much protein do I need?”
0.8-1.2 grams per pound of body weight (ideal body weight) this varies depending on your muscle mass, your activity level, and your goals. it also can vary depending on whether you’re recovering from injury or surgery, or trying to BUILD muscle mass (you need more if you are!
