health risk of doin FULL BLOWN KETO,NO CARBS UP

[MindGame]

"SKD. This is where you just restrict carbs, go into ketosis, and stay there for long periods until you've reached your fat loss goals" -Keto.org

this is what i was basically doin for 3weeks straight,can this be harmful? in a way if i do 4weeks? is their signs i should look for?

Harmful? Someone else may answer that, but it definitely isn't optimal, in my opinion.

Among other things, you lose the benefits that the refeed has on your leptin levels. Try reading some of Lyle Mcdonald's more recent statements, like this:

Basically, he is now saying that it isn't the Keto protion of the CKD that works, but the fact that you use a periodic carb-up, or refeed.

Most people here seem to swear by the Keto diets. That's fine; whatever works for you. But I have to agree with Lyle; basically any low-calorie type of diet (with some caveats, like enough protein, EFA's, etc) will work during the week, as long as you are doing some form of refeed.

thx,what is leptin levels?

 

[Hoffmeister]

My personal, very simplified take on it is that the refeed raises the level of leptin, which in essence "resets" your bodies metabolism, and keeps it from going into "starvation" mode.

But here are some more detailed explanations:

Remember too, that a Standard Keto Diet is a lot different than CKDs in the number of carbs you consume. After the induction phase of an SKD, you want to begin to gradually up the carbs until you are just barely still in ketosis. You don't stay completely carb restricted like you do on CKDs. The added carbs helps keep liver and muscle glycogen replenished and will help with leptin levels too. If you completely carb restrict ~<20g/day for extended time, your body will have to make glucose from protein in order to feed the brain and liver. In the absence of enough dietary protein to fuel that and muscle repair, you will sacrifice muscle. My opinion is that SKDs are good for people that aren't going to be working out intensely.. If your only exercise is light to moderate cardio, and you want to lose weight, it's a good way.. If you are lifting, it's very hard to balance getting enough carbs against the risk of knocking yourself out of ketosis. I hope this helps.

i had to do that for 3 months and the only possible negative may be loss of a bit of muscle

i've been in ketosis for 3 months at a time in the past and had absolutely no problems at all...

trained hard... eat steaks and eggs like crazy... actually gained lean muscle and cut bodyfat like a mofo!

blood tests actually showed improvements and lowered cholesterol...
