FWIW, I just started STC 2.0, but prior to that I had been doing Jiu-Jitsu and Muay Thai on a carnivore diet. For the high intensity stuff, like repeat sparring or rolling rounds, I found that I ran out of gas too quickly. So, I added jasmine white rice back to my diet. That helped with gas tank, although I did notice some minor increase in joint inflammation/muscle soreness. So far on STC 2.0, I've been ok without the carbs, but I'm also not going into that +90% of max heart rate territory, which is where I notice the real need for more carbs in the diet. Hope this helps.

Kyle,
Do you have a recommendation for protein powder? I am still eating a meat-centric, low carb diet, but would like to increase the amount of protein I am taking in without breaking the bank on daily 20 oz. ribeyes. I have looked at several protein powders but they all seem to have stuff I don't want - sucralose, soy products, etc.
Thank you sir!
Brandon

That's a great question. There are a few out there- Jay Robb, Jocko Molk, Naked Whey. I'm sure there are more, but those are the three that come to mind at first. You'll pay a fairly hefty expense for them all as there's more that goes into creating a product like that with the criteria you want, but it's an option.

FWIW, I've had good luck with True Nutrition, https://truenutrition.com/ , and they seem competitive on price. You can also create custom blends if you want to add certain complementary supplements (e.g., BCAAs, etc.). Also, the Costco in my area carries Ascent Protein, which seems to have a good reputation. Ascent Protein is a bit spendy without the Costco bulk pricing. I'm no nutritionist or doc, but those are two options that have worked for me.

Welcome to MTNTOUGH, Stewart! Pumped to have you!

The (bad), but leading advice for nutrition is always "give it a shot...see how you feel..."
With that said, the programs have a fairly high intensity to them. That type of work requires carbohydrate as the main fuel.

So, would you 'survive'? Yes, of course...

Would you be able to keep a pace that pushes your physicality in a way that allows you to get better? Well, that goes back to post one (give it a shot), but we've seen much more favorable outcomes in that type of work when someone is including sources of great, slow-digesting carbohydrates as a part of their nutrition plan.

You're welcome, Stewart. Lots of factors to consider with a T2DM, so be sure to factor all of that in.
But like we say with nutrition: The dose is always what makes the poison....with everything.
