Summary
Episode #213
In this Fasting Q&A episode, hosted by Coach Lisa Chance, Dr. Jason Fung answers questions from the TFM Community:
- Can you compare T1D, T2D, LADA, and MODY? [01:52]
- What are the best fasting protocols and diet for autoimmune conditions? [11:40]
- Is it possible to be successful if you eat mostly vegan/vegetarian, as I worry about the higher carbs with this type of eating? [13:44]
- Does each hour you fast have added benefits? [20:44]
- A recent study done by University of Colorado Boulder confirms that metabolically healthy women tend to experience menopause later, with the study linking later menopause (age 55+) to better vascular health and reduced heart disease risk. Could you discuss how this research connects metabolic health factors like mitochondrial function and insulin sensitivity to delayed menopause onset and improved cardiovascular outcomes? [25:44]

| 0:00.0 | if you eat a meal at 9 p.m. versus 6 p.m., there's a measurable difference. You can take the same |
| 0:05.6 | meal, but there's a measurable difference in terms of how high your glucose and how high your |
| 0:10.0 | insulin goes. Same meal, same food. |
| 0:19.0 | Hello, my name is Lisa Chance, and I'm a fasting coach here at Tfm and we are here today with |
| 0:24.6 | our very own Dr. Jason Fung for our monthly Q&A. |
| 0:28.6 | In this monthly Q&A, Dr. Fung answers questions submitted by our TFM community members. |
| 0:35.6 | And hello to our podcast listeners who will be able to listen to this Q&A with Dr. |
| 0:41.4 | Fung in a few weeks after our regular community members. |
| 0:45.0 | So Dr. Fung, I'm going to dive right in here and I have somebody send several questions |
| 0:51.6 | in about LADA and the difference between that and type 1 diabetes |
| 0:57.2 | and the diagnostic on that. And I realized that we really hadn't looked at Modi either. Is that how |
| 1:03.4 | you pronounce it, M-O-D-Y? Moody, yeah. And I thought it would be nice if you could compare |
| 1:08.4 | those three, Type 1, Lata, and Modi. |
| 1:12.1 | And tell us how you differentiate insulin level and fasting blood sugar levels. |
| 1:18.1 | Yeah, so there's really two types of diabetes, type 1 and type 2. |
| 1:22.8 | And they're basically, when you say diabetes, it basically means that there's too much glucose in the blood, right? |
| 1:30.5 | That's how it's diagnosed. But the pathophysiology is different between type 1 and type 2. |
| 1:35.5 | Essentially, you have too much insulin in type 2 diabetes and two little insulin in type 1 diabetes. |
| 1:42.1 | And it seems strange, but they both actually cause the same |
| 1:45.2 | high blood glucose. So diabetes itself just means high blood glucose. You could have something |
| 1:50.5 | completely separate like steroid-induced diabetes, which is caused by a certain medication. And that |
| 1:56.1 | is separate. But again, it causes high blood sugars and therefore it's called diabetes. But the two main |
