Regarding the Crack the Fat Loss Code Diet:
About 10 years ago I lost 85 lbs on Atkins. So I have a fair amount of experience with low carb diets....but clearly this diet is unique.The first 7 days definitely seem like an "Atkins Style" diet.
I got into a very strong ketosis (as evidenced by the dark pink ketose strips run under your urine stream, which you can get from the pharmacy for $10) I think this is where some confusion lies. The main weightloss in the first week of any ketogenic diet is mainly water weight and just a couple pounds of fat after the 3rd or 4th day. The body is depleting the glycogen stores in the liver and you are urinating the water out. After about 3 days you are urinating ketone bodies, a bi-product of the breakdown of stored body fat. That's why the ketose dip stick turns pink.

The gal who lost 16 lbs in her fist week probably has a lot more weight to lose than someone losing only 7 or 8 (all things being equal). Or if someone the same weight has been eating low carb for awhile before starting the diet, they may not have the same glycogen stores in their liver. So don't be disappointed if you only lose 4 or 5 the first week. As long as your ketose dip stick is light pink (tracing) to dark purple....you are burning your own body fat...and that the goal right?
I am on day 11 and very happy with a 9 lb loss. (I have thyroid issues so I have to fight for every pound) I haven't had a carb up day yet but so far my ketose strip is still at least light pink (means I am tracing in ketosis and burning my own body fat).
I will be curious to see what happens 24 hours after carb-up day or a cheat day down the road. This is about how long it takes for the carbs to knock you out of ketosis. I usually feel lousy for a few hours while my body is fighting to get back into ketosis. (cold, sleepy, hungry, craving carbs) I hope that isn't the case here. However, drinking lots of water and getting back on track (low carb)right away, gets you back into ketosis pretty quickly. I am guessing this is what is going to happen.
My frustration with Atkins is I could only do it for a month at a time because of carb cravings and plateaus....so I would alternate Jenny Craig with Atkins. I never really lost on Jenny but I got all the carbs I wanted and it gave me a break until I was ready to resume Atkins...and at least I didn't gain on Jenny

.
I hope this diet will be the best of both worlds. More weight loss than a Jenny Craig but less boring than Atkins. I'm Psyched!
