As I mentioned ketogenic diets are huge

and I firmly believe that they can be very beneficial for weight loss,

for all kinds of health conditions, but so can low-carb.

I think sometimes we forget about low-carb.

I think some of it may have to do with how do you define a ketogenic diet.

There's different definitions.

From the people I've talked to,

let's say most people would... maybe 20 g or less per day as a ketogenic diet.

I don't know, some people would say it depends on the individual,

and that's kind of how I feel

because people will produce ketones at different carb levels,

depending on lots of things, insulin sensitivity and how active they are.

But let's say 20 g or less per day.

And over that it would be like a very low-carb to low-carb diet.

So I think they can both be beneficial.

You need to find what works best for you.

You know when we do diet studies comparing low-carb or ketogenic diets,

it's always compared to a high carb diet whatever it is.

To the Mediterranean diet or to the Dash diet or to a low-fat diet.

It's never comparing less than 20 g per day to 50 g per day.

I don't know if that study is ever going to get done,

I think we'd all be interested in it,

but I think also I would suspect that if you did like a crossover study

where you had people follow each for a month

with the washout period in between,

you would find that some people did better in terms of blood sugar, weight,

just how they felt overall, with a very, very low-carb ketogenic diet

and others would do better with a little more moderate intake of carbs

and then some would have really no difference.

And I just think it is important to keep in mind.
