I first interviewed Dr. Michael Ruscio in the podcast episode "Why Healthy People Get Broken Guts, And What You Can Do About It." In that discussion, we delve into: -Dr. Ruscio’s personal diet, and what his typical day looks like (including his meal of choice at Whole Foods)… -The surprising things that happen to your gut when you combine calories and high levels of physical activity… -Whether athletes should fast, and what happens when an exercise enthusiast “stops the flow of calories” and fasts… -How an “elemental diet” works to reduce stress on the gut… -When you actually should consider starving the bacteria in your gut… -Whether you can combat “overstressing” the gut with food by simply using things like digestive enzymes… -The biggest mistake most people make with cleanses, enemas and detoxing… -How you can heal damage to the valves passing through your gut… -If you could test anything and everything going in your gut, what you should test… -And much more!

Today, Dr. Ruscio is back with the latest research on carbohydrates and the gut, and during Part 2 of our discussion, we dive into:
-Michael's take on the statement that "all carbs get converted to glucose so there is no such thing as bad carbs" and whether there is a consensus regarding the role of all carbs, good carbs, bad carbs, high carbs and low carbs...[8:11]
-Why Michael doesn't like food allergy tests or use them much in his practice...[13:10]
-The role of carbohydrates or carbohydrate avoidance when it comes to a digestive condition like IBS (gas, bloating, abdominal pain, constipation, lose stools)...[19:40, 21:45 & 32:10]
-How the microbiota influences this and whether people with digestive conditions need to feed their healthy bacteria in order to feel better, and if so, how do they do that if they're eating low carb...[20:20 & 23:45]
-Whether a low carb diet really damages your thyroid...[40:40]
-The impact of artificial sweeteners on a low-carb diet and the truth about stevia...[56:15]
-Whether you really need to run like the plague when a supplement or bar has, say, 10g or 20g of carbohydrates...[52:30]
-The impact of a low-carbohydrate diet on testosterone levels...[64:30]
-And much more!
