Hey guys, so I recently had a question from someone that wanted to know, will protein

bump me out of ketosis?

Okay, they're concerned if I eat too much protein, am I going to be in ketosis?

Well, let's just take a look at this book right here, Guidance Physiology, page 830.

It says, other factors that stimulate insinsecretion, amino acids.

In addition to excess glucose stimulating insulin secretion, many of the amino acids have a similar

effect.

Amino acids administered in the absence of a rise in blood glucose cause only a small increase

in insulin secretion.

However, when administered at the same time that the blood glucose concentration is elevated,

the glucose induced secretion of insulin may be as much as doubled.

So the behavior of protein in a low carbohydrate environment is acts very, very differently.

So if you want to know what that means, it's roughly 0.7 grams per kilogram of lean body mass.

So for myself, I need about 58 grams of protein per day, okay?

So that's somewhere between 5 to 7 ounces, depending on the type of protein you consume per meal.

But I wanted to mention this one point about the purpose of protein.

Sometimes people think it's a backup fuel source, it's not.

When you go on a fast, even a fast for like two days or even three days, your muscles aren't

there to act as a backup fuel. You're not going to create atrophy of your muscles, okay?

The purpose of protein is to replace body tissue parts.

So it's not going to be acting primarily as a fuel reserve, okay?

It can turn protein into glucose, but that's going to be mainly dietary protein.
