Please remember, the fat fast was never meant to be a long term thing, just enough to get really resistant people into ketosis.

Have you tried the blood test for ketones? I use the urine strips, which work well for me, but ketones don't show there for some people.

Starting over with Fat Fast today. I think this plan helps as far as kick starting you into ketosis. However over the holidays were rough

I'm into day four. I wasn't going to measure myself til after day five. So far so good. It REALLY does control hunger and catapulted me into ketosis. Not for the faint of heart, but the food choices really aren't too bad. I'll post tomorrow. I hope to be down some!

So how's it going?

I am one of those people who has a really hard time getting into ketosis, I agree, a long term diet of 'fat fast' probably isn't good, but it was never recommended as a long term solution, just a kick start to getting you into ketosis and losing some initial weight for motivation. And don't we all need some kind of motivation? Whether its looking good for an event or overall better health. So I am on day #2 of this. To be honest people shouldn't worry about others doing this thing for long, because it's hard to stay on. I'm going to give it five days and will post results. Others may hate on it, but for some it might be just the thing to kick them into Induction. All those haters will low carb, surely should either 1. read the book 2. realize not everyone can kick a sugar addiction by just 'cutting back' on sugar.

Why do people here have to be so nasty?

I recall that the OP was also taking diet pills because Snookie is the spokesperson.

That's why people are questioning the references.


Also, some of her comments have been completely deleted so you aren't reading the original thread.

If memory serves (been a while since I read the book), the fat fast was intended only for people who couldn't get into ketosis any other way. I believe it was discouraged for people who could get into ketosis doing induction, as it would be too extreme.

As for those who quit Atkins and gained weight, well duh! You go back to eating what made you fat in the first place, of course it will make you fat again. Same thing applies to low calorie diets.

Well, I gained weight adding back carbs. No problem! I just keep them low. I must be doing something right because I have kept at maintenance for a year now.

I feel like some of the responses to the original thread are going a bit too far. Why criticize a person for reading and asking questions in regards to a type of food or diet. I don't think trashing there resources are the way to go about it.

I for one am following an atkins style diet through a Medical center and an MD. I am on a low carbohydrate (50g), moderate calorie (1000 below) and be certain to get at least 75 g of protein in a day. This is a SAFE and effective way to lose weight because its being medically managed.

You do not gain the weight back when you increase your carbs. If you lose a dramatic amount of weight eating around 50 carbs a day you may lose a moderate amount of weight at 100 and you might maintain your weight around 150-250. Going back to old eating habits is how the weight is gained back.

I personally have lost a lot of weight, and my bloodwork has improved on Atkins. I tried the fat fast once, and hated it.. cream cheese and macadamia nuts, water, and chicken w/ mayo. I guess I could have had some avocado if I liked the taste.

However I have lost 130 over 3 years on regular Atkins, so why would I do this to lose faster. It is interesting, and I can say that the higher my percentage of fat, the faster I lose ( and get diarrhea ). By the end of the week I was much lighter, and had a sore bottom.

I think if I wanted to promote the fat fast, I would recommend the chapter of it in his book, and let people read that. This article is quoting from that book, who we are getting it from second hand even from Dr. Atkins.. he read them, and says what they represent. I can say that even as uncomfortable as it was for me, I lost weight. That is no proof on how it will affect others, and most important of all 99% of people would not do this diet. Also I think any temporary diet is not a good idea. Eventually you have to go back to eating less fat, more carbs, and you will gain back some weight.

I eat 27 net carbs a day, 8 serving of vegetables, and most people here would consider my diet extreme, but it is nowhere near as extreme as the fat fast, and Dr. Atkins himself only recommended it for the few people who couldn't lose on Induction.. to break all addictions, and cravings, not for weight loss. He was a cardiologist, not a nutritionist. Weight loss was a secondary effect. He promoted Atkins as a heart healthy diet.

I could argue that it(Atkins) has improved my bloodwork immensely, but that doesn't apply to all people, so I won't waste my time. I think it can be done in a healthy manner, but it is not something people should do just because they can lose a bunch of weight. I think anyone who can do Induction, and then start adding healthy carbs back in while experimenting to see how each one affects them , and find they can have quite a few carbs and lose weight should just do Atkins / low carb. What benefit besides rapid weight loss would they see? would it be temporary? What's the hurry?

Last, A large % of the population have no need to do low carb.. EVER..

This upsets me for this reason.. I think low carb is beneficial to some people, me included.. However when people think of Atkins, or even low carb in general they think of Induction. This leads them to quote 20 carbs, or no carb. So while I am arguing that this is 2 weeks of one form of low carb, and 95% of the time on a low carb diet, you wouldn't be even at that level, you throw out 90% fat, low carb.

I hope you are trying to promote low carb, but you are scaring more people than attracting them. I think if I was thinking of low carb, and read this thread, I would reconsider. Lean meats, 10-12 servings of vegetables, fruit, cheese, nuts, with butter, and olive oil is a big enough leap for people to make. Being able to add back in other carbs as they move up the carb ladder is what we should be promoting. For the few who can't handle certain carbs, we want them to just cut those particular carbs out, not all carbs, and most temporarily. If they have no addiction or trigger foods, they can do something like South Beach, which has lower carbs, or just eat a cleaner diet like SP promotes.

I could go on.. I don't want to seem angry, but I think you are doing harm. A small group of people need low carb, and this does not help with the us vs. them attitudes. Nobody is going to support a 90% fat diet. I am glad you found success with it personally, and hope you reach your weight loss goals doing regular low carb or any other plan that works for you.

Just wanted some thoughts on Atkins. Women's World magazine seemed to approve in a recent article. They say it has changed drastically from what it used to be. HMMM?

As I said earlier in the thread, it is a short term diet. And for what it's worth, the Keckiwick & Pawan study is from *1956* & was published in the Lancet which is a peer reviewed journal. The fact is, researchers have known the effects of carbs for over a 100 years. I'm adding carbs back to my diet and upping my calories beginning at the end of the week, but this has been an eye opening experience for sure that I won't forget.

Everybody breath...OK are we all feeling better.

To the original poster: I respect your choice as an adult to eat as you wish and select a weight lose program as you desire.

But realize that is a site dedicated to a healthy and safe weight loss approach that one can follow and implement for the rest of one's life.

Yes, there are ways to cut calories, alter nutrient percentages that brings about a faster weight loss. Staying on such an approach for one week will probably not harm a healthy adult---but it is in no way and approved, healthy, safe, evidence based, or appropriate weight loss technique.

Yes, there are folks who are medically at risk and need a much faster form of weight loss. They often use a very low calorie diet (800 calories); but... they need to be monitored weekly by their team of health professionals to assure safety along the way.

Many of the links that you provide are not peer-reviewed, published, quality research studies. A good site to locate such research is at:

We encourage our members to reference such reliable research studies to support nutrition and weight loss information.

Thanks for using our Sparkpeople guidelines in the future.

It is not a healthy way to lose weight and no matter how you slice it, if you continually consume less than your daily caloric requirements you will lose weight.

Do you know how to do research?

Wikipedia doesn't count as research. Neither do websites that are picking and choosing what "facts" to report and then try to sell you something.

Google scholar - actual published research articles and abstracts - did not show anything on Atkin's fat fast.

How do you know there is research if there isn't anything published?

If it works for you and you are healthy, fine. But that doesn't mean the results are applicable to everyone.

The Atkins Fat Fast is part of Robert Atkins legacy; he wrote about it in the New Revolution book. As far as the other researchers go, Keckiwick & John Benoit et al, no there is not as much written about them in widely available print but I take it on my own personal experience, which is about 15 years of dieting and 10 years solid on lower carb/paleo/primal type diet that hell yes this Fat Fast thing is true. But actually, to find out more about who John Benoit is an what was the nature/scope of his professional work you would need to do your own research, something I suspect you are probably too lazy to do........

Here is an introductory wikipedia article to get your started: Medical Research related to low carbohydrate diets:

Where's the study or the abstract of the study to prove efficacy?

You can't just quote an article with no resources cited as being legitimate; and then keep repeating the link to this article as something to be regarded as fact.

I looked up the Kekwick Diet on Google Scholar... First piece of research that comes up is from 1964 "The effect of high fat and high carbohydrate diets on rates of weight loss in mice"

Mice are not people and the research isn't current.

FUNSTYLE Posts: 180

Um, there was a substantial study done by a researcher named John Benoit and also a man named Keckiwick as well as Atkins himself. Google it online, it is true!!

To help these metabolically resistant people, Dr. Atkins has modified what he calls "the most effective weight-loss eating pattern ever described." British researchers Alan Kekwick and Gaston Pawan developed it, and Frederick Benoit and his team confirmed its superiority in burning off fat, compared to an absolute total fast. This extreme diet consists of 1,000 calories daily, comprised of 90 percent fat. No other weight-loss regimen has matched its ability to burn off stored fat. Dr. Atkins modified the Kekwick diet to make it as enjoyable as possible and dubbed it the "Fat Fast." He tried it on scores of patients and found it often worked for those who were unable to lose weight in any other safe, drug-free way.


The fat fast was shown to PRESERVE muscle tissue and burn ONLY fat, something the other 1,000 calorie diets were unable to do!

Do your own research!!

Never take health advice from a web page that has a shopping cart at the top.

There's no research behind what they're saying here. They don't cite their sources, and from the description here, the "experiments" involved comparing people on a 1000-calorie nearly all-fat diet to people on a diet that didn't specifically restrict calories. Here's how they themselves describe it:

"Lowering the caloric intake accelerates the need to burn up body fat�thus the 1,000-calorie limit.
The Fat Fast is one controlled carb program where you do have to count calories."

Wow, lowering caloric intake accelerates burning body fat? Really? Who'da thunk it?

They didn't compare people on this 1000 calorie diet to people on any other 1000 calorie diet. Without that comparison, this is just silliness. Eat 1000 calories of macadamia nuts, brie cheese, whipping cream, and mayonnaise, and you'll lose weight. Eat 1000 calories of chicken breast, whole wheat bread, spinach, and bananas, and you'll lose weight. Eat 1000 calories of Twinkies and Pixie Stix, and you'll lose weight. There's nothing in this article that would refute that.

I am only doing the fast, not the actual Atkins diet. Have done higher protein, lower carb type diet for a decade, works fine for me. I am actually trying to *gain* back some weight but in the meantime thought I would try the fat fast to see if it does indeed melt fat off the body. Quite happy to say that it DOES.

FUNSTYLE Posts: 180
1/16/12 4:55 P

Nope you would have to read the research to underestand. It is a *short-term* diet- a few days to a week at most. And no, 1,000 calories is not too low for a few days at most!

High fat diets do help weight loss dramatically. I did one long time ago and I lost a lot in just a few months. For me, the issue was that the diet didn't prepare my mind for the long run. When i reached my goal weight and went back to eating normal, I gained all the weight back at an incredible speed. I could see my belt getting larger and larger every week. At the end of a year I regained everything back plus about 30% more...

But if you do it watching calories and as a temporary fix to lose the first pounds, then I guess it could be useful.

Yeah, I read the New Diet Revolution and technically, it all makes sense. Strangely, today with a combination approach of high carbs at the beginning and high protein now I've lost at a higher speed than I did with Atkins, just 12 years later... Maybe it's all about the calories, but hey, what do I know...

Make a planned exit from the diet to a balanced approach and you most likely should be fine. Remember to check your biochemistry regularily in the meantime.

Best of success.

1,000 calories is too low. Good luck with it, but I feel the Atkins diet is misguided. I know a couple people who tried it and now that they're off it, they are just as overweight as ever. In order to have success with any diet, it needs to be sustainable otherwise it becomes too difficult to maintain.

90% fat? No thank you! I believe that it is the 1,000 calorie limit that is making you lose weight. I like fat and all, but I prefer to walk not slide.

I've been doing this the last few days and it is really eye opening. From what I've read, Atkins and other researchers found this to be the most effective short-term fat loss approach in the world- a diet of 1,000 calories and 75-90% fat. This type of diet was shown to be more effective than 1,000 calories of carbs, or carbs with protein etc, showing ultimately that the body loses fat best on a diet high in fat. On the high fat diet participants lost only fat, not muscle. Atkins wrote about it in his New Revolution book and there is some info about it online. Very interesting and worth checking out.
