Questions about the claimed benefits of weight loss 25.10.2025 8:25
I write a lot here about the fallacy of blaming health issues on body size. Today I want to talk about the tendency to credit weight loss for physical, psychological, and social benefits. For example, someone will (at least short term) lose weight and offer a testimonial about how much better they feel, how much more they are doing in the world etc. Or a study will determine that Health Related Qu...

Quick Guide - Expanding Thinking About Weight And Health 18.10.2025 3:47
I got the following question from reader Katrina: “You spoke to my doctoral program recently and in the Q&A you said something about poking holes into people’s thinking where better ideas could fall in. In the past I’ve talked to my doctor about research. I love the research posts you make but I know my doctor isn’t going to read or listen to something that long (he really should he just won’t!) D...
New Drug to Tolerate Weight Loss Drugs? 15.10.2025 10:41
One of the things I’m seeing with the rise of GLP-1 weight loss drugs is other companies trying to use these drugs as a profit center. Today we’ll look at a drug that is seeking approval to help those who take GLP-1s avoid some of the adverse events.

Identifying Two Dangerous Lies in Weight and Healthcare 11.10.2025 6:29
I write a lot here about the specific lies, obfuscations, and shenanigans done by the weight loss industry. But there are two overarching lies that I think may do the most harm in weight and healthcare sometimes consciously and sometimes subconsciously - as part of the unstated background of decisions around purchasing, care, and accommodation.

Reader Question - What’s in it for Novo Nordisk? 08.10.2025 11:27
After I posted the final part of my 3-part series on GLP-1s and kidney function, I got a question from reader Liza:“I appreciate how you always talk about how the authors get money from the drug company, I think it’s important to know. As I read this newsletter [ GLP-1 and Kidney Function Part 3 ] I was wondering if it is possible to calculate how much the drug company themself would make?” This i...

In part 1 and 2 we explored the document “Person-Centered Conversations: Weight Management and Type 2 Diabetes” that was put out by the Association of Diabetes Care and Education Specialists (ADCES) as a “framework” document.

Today we’re going to l...
Analyzing ADCES Conversation Guide for Weight and Type 2 Diabetes - Part 1 24.09.2025 7:30
I recently got this question from reader Emily: I work as a diabetes educator and the place where I work just sent this document to everyone and told us that we should use it when talking to “o-word” patients. It doesn’t seem right to me at all can you do some analysis so I can push back? Thanks for asking Emily, I will do my best. The document she is referring to is called “Person-Centered Conver...
GLP-1s and Kidney Function - Part 3 20.09.2025 25:05

GLP-1s and Kidney Function Part 1 13.09.2025 22:03
As I promised, I’m doing some deep dives into the research and claims around GLP-1 agonist drugs for actual health uses other than their use in managing Type 2 Diabetes. For this series, I’ll be doing the deep dives as well as analyzing the studies using the framework that I discussed here . Kidney-related health is one of the claimed uses I’m most often asked about with GLP1s, that providers have...

What if they tell you that you have to weigh-in? 03.09.2025 5:40
This came up during a monthly Subscriber Ask Me Anything . Many patients, of all sizes, choose to opt-out of routine weigh-ins for a lot of reasons. But what happens when you decline a routine clinical weigh-in (again, not a medically necessary weigh-in that has a specific medical purpose like dosing medication,) but one that is just being done because you are at a doctor’s office) and they tell y...
Reader Question - Framework for Analysis of All These Other GLP-1 Uses 30.08.2025 8:31
I recently heard from reader Evelynn who asked : It seems like every other day I see a new supposed use for the GLP drugs. This just seems fishy to me. Are they really some kind of all purpose wonder drug? Get full access to Weight and Healthcare at weightandhealthcare.substack.com/subscribe

In part 1 we discussed the issues with the study “Energy expenditure and ob*sity across the economic spectrum” by McGrosky et al. Literally hundreds of people reached out to me to write about it and most of them were asking about the article from the Washington Post “What causes ob*sity? A major new study is upending common wisdom.” Today I’m going to talk about that article. If you haven’t read p...

Questions About Weight and Surgical Complications Part 1 - The Basics 09.08.2025 6:21
BMI-based denials of care are devastating and can have serious negative impacts on people’s health, lives, and quality of life. In some cases they are, in fact, life or death. I have a series here that talks about this in detail, including options if you are dealing with a BMI-based denial of care and resources if you want to fight them. Today I want to talk about a common reason that is used to (...
ABC News' Love Letter to Diet Drugs - Part 2 Sell the Premise, Sell the Bit 06.08.2025 13:08
In part 1 I started discussing the ABC News article “GLP-1s work but when they're stopped, the effects stop too: Expert” We discussed the fact that in order to buy the claims their “expert” makes, you first have to buy the dubious claim that simply existing in a higher-weight body, regardless of actual health status, is a health condition requiring treatment (which I wrote about in detail here and...
ABC News' Love Letter to Diet Drugs - Part 1 Buy the Premise, Buy the Bit 02.08.2025 8:35
There are a couple of online articles floating around that literally hundred of you have asked me to write about. One is the Washington Post “reporting” on the study about eating and body size. That study is…a lot, so while I’m slogging through that article and the study it references, today I’m going to write about the other article. Published by ABC News and called “GLP-1s work but when they're...

4 Questions to Ask Before Making Health Recommendations to Higher-Weight People 26.07.2025 7:39
A couple years ago I wrote a piece about what to think about before offering unsolicited advice to higher-weight friends/family/strangers about their health . Today’s piece extends from that. While it can apply to family/friends/randos at the drug store, this is intended for healthcare providers and other health/public health professionals and educators whether you are one yourself, or you want to...
Weight Loss Is Not a Substitute for Healthcare: Part 5 - What Can Be Done? 23.07.2025 9:46
In part 1 we discussed the basics of substituting weight loss for healthcare and accommodation. In part 2 we discussed issues with the likelihood of achieving weight loss, even if it was appropriate to insist that higher-weight patients become thinner before accessing care (and I do not think it is). In part 3 , we discussed the issues of weight loss being promoted as a solution to accessibility....
