The first time I was doing keto, about 15 years ago, I went to a DO for a completely unrelated reason. It was my first visit with this DO so he was doing all of the initial check in stuff. The exchange went like this:

DO: You weigh 216 lbs. At your height that makes you obese

Me: okay

DO: Are you on any sort of special diet?

Me: yeah, I'm on the keto diet

DO: keto? Why are you on the keto diet?

Me: well, you did just call me obese...

I chose a DO for this very reason. However, during my first appointment, they started by praising my fitness and said he wished all his patients looked this healthy. He then proceeded to say my LDL was too high and he was going to put me on statins. I was like slow down.

Not necessarily. There are plenty who practice pretty mainstream medicine.

I've had good luck with both MDs and DOs. When I have to switch doctors, I pretty much interview them to see if I want to be their patient.

Anecdotal of course, but I went to a DO recently at the end of my 15 day fast to get some blood work done. Didn’t even bat an eye when I told him I was mostly high protein keto and just finishing a 15 day fast. Ordered the bloodwork and then when the results came in he correctly interpreted it and told me why certain values were higher than the normal range due to my fasting and keto diet. Because I’ve done this a while now I knew roughly where my numbers would/should be and why, but it was a pleasant surprise to have a doctor who was also familiar with both keto and extended fasting who could also explain why the numbers were what they were without freaking out and reaching for the prescription pad.

My daughter is a DO. She chose a DO program because it was less competitive ( but perhaps more rigorous because in addition to allopathic medicine they must learn osteopathic manipulation).

They had exactly TWO lectures on nutrition. Both professors taught them what they needed to know to pass the exams to get their licenses to practice medicine, and both talked positively about keto off the record . One was an endocrinologist and he talked about his struggle to stop hospital RDs from shoving carbs into his diabetic patients to no avail.

In pediatric residency daughter was one of 2 DO’s in her program. She swallowed the whole “kids with type one have to have normalcy in their lives do carbs are OK. We just adjust insulin for it. Hypos are more dangerous than too many carbs.”

So mostly no.

They are taught to give lip service to wholistic ideals. But many practice allopathic medicine in the traditional MD way. Some rogue independent practitioners might embrace keto, but they are often pariahs in the community because they may also be anti-vax and do a lot of unproven treatment for things like lime disease and fibromyalgia type cases.

The good DOs often keep a low profile because they get a lot of flack from the MD’s and also the community who doesn’t always understand what DO’s are.

Our beloved family doctors who delivered both of my kids were DO’s and one of them was the medical director of our oldest and largest city hospital. But they weren’t different than any MD I’ve had since they retired. One told me to go on an 800 calorie diet of all carbs to treat my PCOS weight gain 🙄

I had an MD endo who taught me about low carb. He told me I could get pregnant and I laughed at him. Six months later I was pregnant. 🤣. He understood what my DO did not.

My PCP is a DO and my first DO that I am aware of. Honestly, didn't even notice at first (new state, new medical system, etc.) and didn't know what a DO was until I looked it up. Anyway, he's very supportive of my keto diet for my diabetes control and we have discussed it quite a bit over the last couple of years since I started seeing him. He's a very attentive doctor and I feel very comfortable with him being so supportive.

Generally speaking, yes.

And sometimes someone goes to DO school bc they can't get into med school

It's not a simple yes or no

I’ve had to train all my PCPs.

I’m an MD and I’ve been keto for years. Not sure it has much to do with training. My own MD docs have all had no issues that I’m keto. My MD neurologist even gave me some great research papers in support of keto for migraines.

My PCP is a DO, and I'm happy with her. Other MD, not at all.

She understands Keto and asks appropriate questions, IMHO.

About 75 percent of my doca are DOs or in the past were DOsall my docs are keto familiar regardless.

My DO acts like a typical PCP. My Naturopath is much more progressive.

I think it goes by the individual doctor. lots.of DOs follow the mainstream ideas.

I don’t bother with doctors unless something is wrong. So I am basically on the once every five years plan.
