1. Your body cleanses itself when you fast. Do you eat lots of bad food? You might not be aware that diet sodas are full of toxins, and drinking them regularly will make your fasts bad. Also, make sure you get NO calories during the fast. This includes stuff like chewing gum. If you get any calories, you'll re-start the entire fasting process because your body starts burning glucose again. Which means you need another 24 hours to get the full effect.
2. Most people don't have bodies that are used to being in ketosis over long periods of time. If you've done a low-carb diet, you should have an easier time fasting in theory. In fact, you shouldn't notice any bad effects at all. If you haven't, your body isn't very effective at using ketones for energy yet, as the only time it uses them is during sleep (and as you probably know your body doesn't need a lot of energy when sleeping). As you start fasting more, your body will get used to burning ketones and you'll have no problem (other then maybe psychological ones) going 24 hours without eating.
Hope this helped.
Thanks for the reply!
But I don't really eat bad food. I'm on the Anabolic Diet and only eat clean foods. No processed sugars (hardly at all even on carb up day), no transfats, etc.
I eat mostly fish, cheese, vegetables and sometimes nuts/quark cheese.
I'll give it another try, maybe you're right and my body just needs to adapt.
Playboy wrote:After reading this, I'm not sure if you're in a state of ketosis while fasting if ketosis burns muscle. However, everything is pretty simple really:
You usually eat carbs, carbs give you glucose. Both your brain and your muscles prefer glucose, I'm not really sure why but I think it's because fat more practical to store. When there's no more glucose, your brain needs to burn something. That's why we have bodyfat, and the brain (dunno about the muscles) burns ketones instead, which as any ADer or ESEer has felt, are more effective and give you better concentration and more energy. Since the ketones come from your body fat, you won't be lacking energy if you don't eat for a while.
Whether this is ketosis or not, I really don't know. However AD has your body using ketones as the main source of fuel, and so does fasting. No real difference.
Your brains run on glucose because fat can't pass the blood-brain barrier. The only other thing that can pass the barrier are ketones.
Your muscles prefer glucose because of the whole ATP system (creatine phosphate and adenosine triphosphate are the most important forms of energy in weight lifting).
To be honest, I have my doubts on the effectivity of ketones. When I did Cyclic Ketogenic Diet (which is even less carbs than AD), I got Keto-breath, was constantly lethargic, etc.
I never had this problem with Anabolic Diet.
That's why I don't really understand the ketosis thing, or that it's a matter of how deep your ketosis is, etc.
According to an article on T-Nation and an interview with Di Pasquale (from Anabolic Diet), it depends on the person. Some people are way more effective in oxidizing fat to use it as energy than others. Some do perfectly well on 30 grams of carbs a day, while others might need to double that amount.
I'm still experimenting, and I'll keep your comments in mind. Thanks again for the reply, I'll let you people know once I've done another fasting day.
