    Does anyone have any experience with high fat low carb diets AKA ketogenic diets?

    I've heard many claims about it improving concentration, raising IQ and cognitive function but it sounds a bit too good to be true.

    Also, why are carbs considered to be the most terrible thing you can put in your body by some people (mostly those promoting Paleo diets)?

    The only medical/neurological benefit I've ever heard is that such diets may reduce seizure frequency in some epileptics. Have never seen any substantiated claims about IQ or cognitive function. Can you cite the studies?

    No studies, just claims by people supporting/being on the diet.

    The only studies I could find were related to epilepsy and and weight loss.

    For example, this article mentions increased GABA levels and "neronal protection".

    I've also heard others like Dave Aspey talk about improved cognitive function with no citations.

    I think the most verified thing one can say is that a high fat diet is more likely to have an adverse effect on intelligence, as it increases the risk of stroke and mini-stroke. Evidence for this is fairly substantial.

    Many yrs ago(20) did the low fat,low carb diets, cycled carbs over 3 day periods and after the metabolism adjusting I did have periods of good energy levels and mental clarity. Although on lower carb and higher energy expenditure days I would get a bit testy.

    I did try a high fat low carb(under 50g/day) and made it all of 5 days. Ketosis is no fun, no joke.

    Sounds like purple-n-gold got smarter after only 5 days of the diet. He'd probably be working in nuclear physics if he had stuck with it another week.

    Google is your friend - dude. Ketogenic diet is WAY more hardcore then Paleo for what its worth. It's an extremely difficult diet.

    I get the feeling on this forum most people don't really want to KNOW the answer to these questions..

    It's like I heard that x or y does that. That seems hard. That x or y thing is stupid right? (Someone chimes in yeah stupid). Poster yeah thats what i thought.

    I really like it, but I can't go Carb free forever. Carbs help me focus when I play tennis for example. But eggs/bacon in the morning, a chicken salad at lunch and ground turkey seasoned and mixed with with squash, broccoli and lima beans with melted cheese is a good example of a daily diet I follow. Difference is that I like to cheat once a week because I think the body needs some carbs.

    Everyone is different. I have been doing modified Atkins (carbs every 1-2 weeks, no sugar, no dairy, no wheat). I normally eat 1-1.5 pounds of meat every day and I feel absolutely great. Furthermore I've lost 25 pounds.

    If I do have energy foods they are always low GI.

    I love ketosis!

    It seems like what you've been doing is a light version of Carbnite. It claims that a low carbs diet coupled with a really high intake of high GI carbs once a week is the best way to lose fat while keeping the muscle loss to a minimum.

    I started it a week ago (so didn't have a carb nite yet) but so far, staying under 30 grams of carbs a day hasn't been hard at all.

    Similar to the TNT Diet. Four weeks of low-carb, high fat, moderate protein. Then you can continue along one of a couple of paths depending on your goals. I am on path least centered on weight loss and most on muscle gain--low carb five days a week, except around exercise, when I have high GI carb/protein before and after. Then two days of low-fat, high carb (mostly low GI), high protein.

    Best shape of my life. Best part is that my mood/energy levels are high and even. Food-wise, I like it because you never get in a rut with always changing things up. I don't beat myself up over cheating. No paleo-esque claims of "eating the right way." It just works for me.

    Yes, this works for me too.

    The biggest challenge is to not get too liberal with the carbs. It is easy to let things slip too far. But I generally find 1-2 days a week where I eat carbs at night before I play tennis to be perfect.

    It's all about finding what works for you.

    How are you guys counting your fibrous carbs and beans? I know some low carb diets dont figure in veggies, but beans and lentils can have a good amout of complex carbs in 'em.

    Generally, fiber isn't counted "against" you for purposes of carb counting. I get all of the fiber I need most days from greens and other non-starchy veggies. I love all beans, so I'll usually cook a crock pot of them for my carbo-load days. Plus, I consume a lot of fruit smoothies before/after workouts.

    I'm not actually sure exactly if what I'm doing would even be considered "low carb." Considering how many windows of time in which I am eating carbs, it really feels like a balanced diet. I just know the net effect is that I eat better than I ever have. Processed foods are the main casualty.

    Ketogenic or low-carb (hence the low part of the name) are not carb free or zero carb. Most of them recommend starting off eating a small amount of carbs while always eating some vegetables each day and then gradually eating more carbohydrates until you find the level your body tolerates well. I've been on a low-carb diet since February 2011 and feel great. My blood numbers for LDLs, HDLs, triglycerides, etc were all excellent the last time I had them checked earlier this year.

    I'm in my 50s and lost about 25 pounds after adopting this way of eating. Sometimes I fall off the wagon but overall I stick to it by keeping starches and sugars at a minimum. I rarely eat bread or potatoes now but sometimes I'll indulge in a chocolate almond bar or two or some other sweet. I don't worry about being in ketosis at all but I do have ketositx and test sometimes but really just out of curiosity rather than an obsession over being in ketosis.

    As far as athletically I haven't had any negative impacts. I lift once or twice a week and after being a 3.5 since 2005 I got bumped up to 4.0 at age 54 so it isn't hurting my tennis. If anything the weight loss helped a good bit and I still have all the energy I need to play singles. This diet doesn't work for everyone but it sure as hell as worked for me. YMMV!
