Which one is most effective in permanent weight loss.

didn't try the meat fast but with the egg fast I didn't lose a pound or an inch and it knocked me OUTTA ketosis...

starnge since i was only eating eggs, butter and mayo for 2.5 days but...

???

Really, your the first person who said they didnt lose.

yah it figures!!!

i don't know what/how the hell happned
i was sooooo good at following it
and actually it wasn't too bad to do

adn i was pretty boring with my menu
hardboiled with mayo or scrambled in butter!

maybe i just really have a reluctant metabolism but i was sooo disappointed when i was outta ketosis

??????

can't hurt to try it though
meat fast may be more interesting though

Neither
Rapid weight loss is the goal of the fat fast not permanent.
The life change that you have to go through to get weight to stay off is the entire plan and that means making the changes for the rest of your life by learning what foods you can and cant eat.
You can stay with induction as long as you want to lose weight and then move on to the other phases of Atkins. You can start with the fat fast and then move onto induction -12 days is the maximum of the fat fast where you limit your calories to 1000 for 4 days then 1200 for a week. The menu is more varied than the egg fast, but it should give the same results.
Only if you are resistant to weight loss should you try this.
