What&#x27;s interesting about this post isn&#x27;t the actual diet advice, but the guidance to track and see what works for you. Different people react to fasting differently - some continue to burn calories and drop weight, some just go into starvation mode, have their BMR crash through the floor, and end up exhausted all the time because their body is fighting like crazy to conserve energy.<p>Likewise - some people, when they start to eat carbs, see their BMR ramp up, are full of energy, and end up running 5-10 miles a day to burn that energy off, and are pumped the rest of the day.<p>Also, focussing on weight to the exclusion of everything else is really horrible. It&#x27;s pretty easy to lose 40-50 pounds and end up being much less healthier than you were before if you aren&#x27;t careful. Having some sense of your V02 max, your strength, endurance, flexibility, etc.. are sometimes as important, if not more important, than what your weight is to +&#x2F;- 20 pounds.<p>Everybody is somewhat different in how they&#x27;ll react to various diet and exercise regimes. Understanding that, and taking a bit of time to watch how your body responds, is the important insight here.

I&#x27;d really like to see this kind of analysis applied to a larger sample.<p>If someone were to put together a little app to make this sort of data collection trivial and upload it to a central (preferably cheap) repository, would people be interested in contributing their data in exchange for analysis?<p>Also, since this is HN, is anyone interested in building something like this? I&#x27;ve got an hour or two a week of spare time to chip in.<p>Unrelated question, mostly for OP: do you know of any publicly available databases of GI&#x2F;GL info? It&#x27;s really important for people with type 1 diabetes (a subject rather dear to my heart), and could also be useful for OpenAPS stuff (<a href="https:&#x2F;&#x2F;github.com&#x2F;openaps" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;openaps</a>).

I don&#x27;t have a weight problem, I learned about ketosis researching natural ways for improving focus and concentration, and somehow came across &quot;bulletproof coffee&quot;. (I&#x27;m only using BP for lack of a better name and I don&#x27;t endorse the stuff they sell online).<p>To my utter surprise, something as stupidly simple as coffee blended with butter with coconut oil (or MCT) first thing in the morning did unbelievable things for mental productivity. After much googling I learned that this is not a fluke, and that there is real science behind it - beta-oxidation, etc, all that good stuff.<p>What&#x27;s most incredible to me is that (1) I didn&#x27;t know about it, I always thought glucose is the only fuel (and I consider myself fairly knowledgeable as far as basic physiology is concerned) and (2) that sugar, especially the industrially produced kind, is about as close to being the root of all evil as it gets and there is nothing wrong with fat at all.

It&#x27;s astonishing (and really awesome) that they were able to extract such a strong signal from daily weight swings! This makes me a lot more optimistic about the possibilities of quantified-self-type stuff.<p>Three things I&#x27;m really curious about:<p>- How significant are the estimates of lifestyle factors? Do you have p-values? If you bootstrap resample, how much do the rankings change at the extremes?<p>- How much cognitive overhead did it impose to collect the data for this? Did you put a lot of effort into designing the tags beforehand or making sure you weighed yourself at a consistent time?<p>- It looks like the predicted delta from going from a &quot;nosleep&quot; day to a &quot;sleep&quot; days is about 1.4 pounds (sleep coef minus nosleep coef). That seems fishy, or at least like it will stop working fairly soon because you can&#x27;t actually lose 1.4 pounds&#x2F;day sustainably. Is it possible there&#x27;s something weird going on with the data or those variables don&#x27;t have the obvious meanings?

This is all good if your goal is weight loss. However weight loss doesn&#x27;t necessarily means higher fitness. Glycogen is fundamental if you do sports, and exercise is a major ingredient in getting fit. If I read correctly, exercise was not a big part of your experiment, how would you suggest modifying the experiment to accommodate one&#x27;s exercising needs?<p>On a side note, I reached a similar conclusion on the role of &quot;carbs at night&quot;, sleeping, and fats, and I read this interesting article <a href="https:&#x2F;&#x2F;aeon.co&#x2F;essays&#x2F;hunger-is-psychological-and-dieting-only-makes-it-worse" rel="nofollow">https:&#x2F;&#x2F;aeon.co&#x2F;essays&#x2F;hunger-is-psychological-and-dieting-o...</a> on the importance, for effective weight loss, of feeling satisfied (I believe there is also a reference to the relationship between eating fats and feeling satisfied).

Just for what it&#x27;s worth, there are several Soylent-like meal replacement products that are explicitly formulated for ketogenesis.

I lost 15 kg (33 lb) over a period of 7 months.<p>* Stopped drinking juice, coke etc. completely * Ate sweets strictly only once a week (like one cake every sunday) * Ate carbs mainly at lunch when doing sport afterwards. In the evening I ate carbs too, but much less.<p>There&#x27;s one thing that all these fasting-guides and tips fail to mention:<p>The fastest way to loose weight is to heighten your resting-energy-consumption, and the fastest way to do this is to gain muscle mass by training.

Totally anecdotal, but I want to second the recommendation of a longer fasting period.<p>I switched to a strict-but-not-religious &quot;no food between 7 pm and 11 am&quot; system (with exceptions for weekends and social occasions).<p>Within a few months I was down 15 pounds (~182 to around ~167) and had shed 4 inches off my waist (~34 to ~30). I&#x27;m about 5&#x27;10&quot; and 41 years old.<p>It&#x27;s definitely helped with physical activity (mostly parkour&#x2F;free running) and I look better. It&#x27;s also <i>more</i> convenient than what I was doing before, since I don&#x27;t have to cook breakfast.<p>The only negative side effect (possibly unrelated) has been that I need a much cooler sleeping environment to be comfortable.<p>The only thing I would add is that I&#x27;m starting to (upside-down) plateau at around 165 and (what my scale says is) 20% body fat. I would love to lose another 5-10 pounds but it&#x27;ll probably be a slow process.

I&#x27;ve been doing ketosis for about 6 months, after having done twice in the past. From my heaviest to today over the last 2 years, I&#x27;m down 50 pounds.<p>The data in this post was cool. I found Dr. Peter Addia&#x27;s analysis to be one of my favorite resources. He&#x27;s a medical doctor who was an overweight endurance athlete, then began doing ketosis. I appreciated an honest scientific analysis of the benefits and drawbacks of ketosis.<p>His blog:<p><a href="http:&#x2F;&#x2F;eatingacademy.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;eatingacademy.com&#x2F;</a><p>As an aside, I think that our attitude toward insulin from a public health perspective is going to change a lot in the next few years.

This is delightfully nerdy and overly analytical, but I can&#x27;t believe someone would go to the extent of creating this yet never think to look for counterarguments against their dieting regimen. Doing this would have given him the answer much sooner.<p>Trying to figure out how the consumption of certain foods correlates with weight gain&#x2F;loss is a waste of time because it&#x27;s simply the caloric content, not the macronutritional content (eg protein vs carbs vs fats). There are dozens of studies showing that only calories matter for weight loss, including vs low-carb, low-fat, and more[1].<p>The author is acting like each food has arbitrary properties that make them food or bad for weight loss. It&#x27;s a good reason to play with ML, but it&#x27;s easier to just count calories. I hate seeing people go down the &quot;good food&#x2F;bad food&quot; path of thinking because they end up overanalyzing the shit out of everything they eat and for no good reason.<p>The glycemic index doesn&#x27;t realistically matter either for a ton of reasons. It hasn&#x27;t been taken seriously as a useful marker when chosing foods for quite some time now. It&#x27;s not a reliable indicator of anything. I posted a summary a few years back that debunks all the insulin&#x2F;GI spike voodoo[2].<p>Low carb diets work, but they only work because they&#x27;re a trick to get you to reduce calories. Look at what you&#x27;re eating and remove all the carb foods. Notice how much your calorie intake dropped. It&#x27;s a simple way of losing weight without counting calories, but that&#x27;s it. The weight loss on keto, atkins, etc have nothing to do with carbs, and everything to do with calorie restriction.<p>It&#x27;s worth noting that low carb diets have great health benefits, however [3].<p>[1]: <a href="http:&#x2F;&#x2F;examine.com&#x2F;nutrition&#x2F;what-should-i-eat-for-weight-loss&#x2F;" rel="nofollow">http:&#x2F;&#x2F;examine.com&#x2F;nutrition&#x2F;what-should-i-eat-for-weight-lo...</a><p>[2]: <a href="https:&#x2F;&#x2F;reddit.com&#x2F;r&#x2F;Fitness&#x2F;comments&#x2F;j853z&#x2F;insulin_an_undeserved_bad_reputation_plus_notes&#x2F;" rel="nofollow">https:&#x2F;&#x2F;reddit.com&#x2F;r&#x2F;Fitness&#x2F;comments&#x2F;j853z&#x2F;insulin_an_undes...</a><p>[3]: <a href="http:&#x2F;&#x2F;examine.com&#x2F;nutrition&#x2F;are-there-health-benefits-of-a-low-carb-diet&#x2F;" rel="nofollow">http:&#x2F;&#x2F;examine.com&#x2F;nutrition&#x2F;are-there-health-benefits-of-a-...</a>

I really like your reading because I went to a time period when everything I read was so misleading even words from doctors. That&#x27;s the time when I tried very hard to improve my health (I gained about 30 lbs since the time I came to this country 15 years ago). To do that, I ate less fat, avoid carbs, getting a lot of exercises (1-3hrs a day, at least 5 days a week), eating oatmeal, even taking statins. And all one failed after another. I went through a lot of things mentioned here. And finally I decided to forget about everything doctors and researchers said. I look at my parents diet and how I was raised and started slowly from there. My health then got improved much better. I&#x27;m glad that you wrote something here for everybody to read. But there&#x27;s one point I would like to add to the recipe: improve mental state by listening to the body (meditation, yoga, brisk walking are good methods), eat only when the body feels hungry and stop eating when it feels full, eat the food that it feels good after eating (you will develop your own list). I lost about 10lbs and I don&#x27;t gain&#x2F;lose any weight for the last 3 years.

As a long-term ketogenic eater (10 years), here are my top simple tips. Unfortunately they were not gleaned using machine learning.<p>1. Watch your protein. Most people when first going keto will eat too much protein and not enough fat. Protein has an insulinogenic effect when eaten in quantity. Keep protein below 8 oz per meal. Don&#x27;t be afraid to eat more fat.<p>2. Avoid cheese. Yes, it&#x27;s technically low carb, but it repeatedly throws me and my girlfriend off (also a low carber).<p>3. Avoid nuts. Yes, like cheese, nuts are delicious. But they&#x27;re a slippery slope. Life will be easier if you avoid them.

&gt; The &#x27;stayhome&#x27; lifestlye, which fell mostly on weekends, is a red-herring, I simply slept longer when I didn&#x27;t have to commute to work.<p>Is it?<p>First, whatever method you use should already take into account that <i>sleep</i> happens together with <i>stayathome</i>. Even basic regressions take into account that.<p>Second, staying at home means your eating binges are constrained by what&#x27;s around you. If it is healthy stuff it might mean weight loss, if it is bread and chips the opposite

The author is wrong that sleeping more just gives less time for eating. Truth is that sleeping more reduces insulin resistance, increases testosterone production in males and puts leptin under control. All three reduce carb craving, push us towards meat and fat and increase natural fat burning.

I might have missed it, but doesn&#x27;t look like ketone levels was one of the factors being measured. You can actually buy ketone pee strips at any drugstore for cheap. Would have been an interesting thing to track, since conventional wisdom says that ketosis is binary, you&#x27;re in it or your not, and the actual ketone level doesn&#x27;t affect the weight loss. I&#x27;m sure this has been put to the test in some experiments already, but maybe applying learning could teach us more and validate&#x2F;invalidate this hypothesis

I collect some of my own data in 1&#x2F;0 form in regard to whether I was productive the day before as well as a few other things (I have a google form for myself that I fill out each morning). I only have a month of data but here is what it spat out:<p><pre><code> FeatureName HashVal MinVal MaxVal Weight RelScore ^dreams 24546 0.00 1.00 +0.0705 47.11% ^shower 215555 0.00 1.00 -0.0239 -15.96% ^exercise 190069 0.00 1.00 -0.0350 -23.41% ^vitamins 252959 0.00 1.00 -0.0442 -29.56% ^write 129676 0.00 1.00 -0.0687 -45.90% ^publish 12600 0.00 1.00 -0.1496 -100.00% </code></pre> Which is to say that when I write and publish I also have the willpower and combined other factors to lose weight.<p>Interestingly I was tracking dreams because I made various changes all at once:<p><pre><code> -phillips hue bulbs -new mattress -new exercise routine (up from nothing) -started taking vitamins -stricter on my diet</code></pre> And was wondering what the cause might be.<p>When I say &quot;dreams&quot; I mean - &quot;did I wake up remembering vivid dreams?&quot;. I wonder now if it&#x27;s related to caloric surplus.<p>I also have minutised step data, nightly minutised sleep data and hourly mood self-reported data that I might try to throw in to the system and see what it says.

This is awesome. I&#x27;d love to see something similar from someone who (intentionally) gained muscle mass. Is it really about high-protein + high-carbs + workout + sleep, or is there a more optimum diet for this.
iopq将近 9 年前
Of course you&#x27;re going to gain weight when you eat carbs. Glycogen contains mostly water and carbs, so if you store glycogen you gain weight, up to 20 lbs from completely depleted.<p>So let&#x27;s say you eat low carb and train very hard for a week. Your muscles will be depleted, your liver will be depleted. You see that you lost 10 lbs! Great! But is it? Maybe you lost one pound of fat and 9 pounds of water. Then you eat NOTHING BUT carbs for three days and you gain 20 lbs. Oh no! But actually it&#x27;s your muscles expanding their capacity to store glycogen (since you trained hard and depleted yourself they will regain even more glycogen than before). You may have not gained ANY FAT AT ALL!<p>I have had great success dieting with medium fat medium carb diets. I try to keep between 180lbs and 220lbs (I&#x27;m 6&#x27;4&quot;). I&#x27;m saying that this kind of tracking is oversimplifying the issue of fat loss - you need to see that you&#x27;re losing fat tissue which involves at least caliper measurements.

If anybody is reading this and curious about Ketosis, I&#x27;d recommend Taubes book (<a href="https:&#x2F;&#x2F;www.amazon.com&#x2F;Why-We-Get-Fat-About&#x2F;dp&#x2F;0307474259" rel="nofollow">https:&#x2F;&#x2F;www.amazon.com&#x2F;Why-We-Get-Fat-About&#x2F;dp&#x2F;0307474259</a>). It&#x27;s a great review of scientific studies done over the years.<p>I read that 4 years ago, spent another 4 months reading the listed studies, convinced myself it was a good plan, and lost 40 pounds with no exercises. I still do LCHF after all these years, and likely will never go back to a traditional diet, it feels great.

This matches my experience of weight loss using high fat diet.

Are there any resources for more vegetarian recipes for high fat low carb food?<p>The article was very impressive. I liked the graphs and presentation.

Sorry for the crosspost&#x2F;copy-and-paste:<p>For me personally this worked quite well for reducing bodyfat:<p>Intermitted fasting[1] and lifting weights 3 times a week[2] and being on a cutting regime[3] (cutting on the rest days with low carb and loading on the workout days wiht more carbs).<p>In the beginning IF was quite difficult but after a while the body get used to it and also I tend to have less cravings during the day. On the loading days&#x2F;workout days I often have a hard time to get enoug calories because I feel full. I am using MyFitnessPal to track what I eat but it&#x27;s more about the macros and not so much about the exact calories (but it&#x27;s also good to get a feeling how much calories different kinds of food has)<p>[1] <a href="http:&#x2F;&#x2F;www.leangains.com&#x2F;2011&#x2F;03&#x2F;intermittent-fasting-for-weight-loss.html" rel="nofollow">http:&#x2F;&#x2F;www.leangains.com&#x2F;2011&#x2F;03&#x2F;intermittent-fasting-for-we...</a> [2] <a href="http:&#x2F;&#x2F;stronglifts.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;stronglifts.com&#x2F;</a> [3] <a href="http:&#x2F;&#x2F;www.lgmacros.com&#x2F;standard-leangains-macro-calculator&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.lgmacros.com&#x2F;standard-leangains-macro-calculator&#x2F;</a> reply

It is funny but I had pretty much the exact weight loss as the OP had doing intermittent fasting. Sadly I wasn&#x27;t as rigorous on the recording of weight loss but I went from 195 to 175 over roughly the same time period as the OP.<p>One thing I found is writing down a plan seems to really help you stick with it.<p>I finally wrote down my workout routine after decade of on and off training. I always logged my workouts but I never wrote the overall plan down. If you are interested in my routine it is here (it has very little to do with diet as I was going to write a follow up some day): <a href="https:&#x2F;&#x2F;gist.github.com&#x2F;agentgt&#x2F;f93b78dbe13870a6d0a1" rel="nofollow">https:&#x2F;&#x2F;gist.github.com&#x2F;agentgt&#x2F;f93b78dbe13870a6d0a1</a><p>I have never publicly posted the routine so if you feel the need to trash it I suppose you can do so in the comment area of the gist but routines are pretty personal anyway (to the OPs point).

A word of advice to those attempting a Ketogenic diet: get your blood work done on a regular basis.<p>If possible, get heart scans done once a year.<p>It&#x27;s easy to slip into a sloppy version of the Ketogenic diet, at which point you&#x27;re consuming lots of unhealthy fats and carbs, you triglycerides and cholesterol could shoot up and put you in shit street.<p>This is a strict diet.

Among words correlated to weight-gain, the least correlated of these is cheeseburgers! Be still my heart (not literally)!

The challenge for me is always knowing what to eat to help me accelerate my weight loss. I need structure. If I don&#x27;t have structure, it&#x27;s easy for me to eat things I shouldn&#x27;t. I started a weight loss program 5 weeks ago called &quot;Ideal Protein,&quot; which uses the Ketosis method. They supply breakfast, lunch, and a snack. I only need to make dinner (plus 2 cups of veggies for lunch). I love how easy it is.<p>I&#x27;m wrapping up week 5 tomorrow and I&#x27;m down 25lbs (~14% of my body weight)! They promise 2-5lbs of fat loss a week. I generally drop around a pound a day, but I&#x27;ll get stuck a few days here and there. This method really works for me.<p>The best part is how fast you lose it. When I did South Beach years ago, it took me months to hit my goal. I have 14lbs left now and I should be able to hit my goal by Labor Day.<p>Give it a try.

I appreciate that the author shared his data because it&#x27;s interesting to compare notes. I embarked on a strict ketogenic diet in 2012 from a significantly higher initial weight and observed a very different pattern of weight loss: <a href="https:&#x2F;&#x2F;i.imgur.com&#x2F;mOt6P.png" rel="nofollow">https:&#x2F;&#x2F;i.imgur.com&#x2F;mOt6P.png</a><p>I hit a loss plateau around 180 lbs that I couldn&#x27;t break through until I began eating on an 8-16 fasting schedule like Ariel mentions in his &quot;Further progress&quot; section.<p>I gave up on the diet during 2015 and have since regained a significant amount of weight, but I suppose that&#x27;s just an opportunity to apply some of the tracking techniques in this article to my next foray.

I don&#x27;t get it, and I&#x27;ve really tried. I&#x27;m referring to the keto diet (though this person&#x27;s approach is obviously extreme overkill). I absolutely love meat, but when I go that low on carbs, I feel like crap. And sure, some people say if I just wait 4 weeks to 6 months my body will adjust, but... why bother?<p>Get a calorie tracker like my fitness pal, set a goal weight loss, stick to it, and 1 lb per week will be a breeze. You don&#x27;t need a fad diet. For me, meticulously paying attention to what I was putting into my body and putting a number next to it made it a no brainer. It was almost gamified at that point.

Semi-related. For those who want to track their weight daily, efficiently, try Fitbit Aria (or one of the cheaper no-brand WiFi scales). Hook it up to Fitbit app, connect that to TrendWeight (<a href="https:&#x2F;&#x2F;trendweight.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;trendweight.com&#x2F;</a>), then throw away the Fitbit app.<p>Whatever your goals are, however serious you are, I find it a great way to keep track. I just stand on this thing once a morning, and forget about it. And now I have a near-daily record, smoothed out with a weekly moving average.

It&#x27;s a great experiment<p>However I think the biggest issue with this is that it&#x27;s considering only a 1 day window. Weight can vary a lot between every day (bladder and bowel contents, muscular glycogen, etc)

Very interesting littlw study. The results seem to make sense, and I&#x27;m impressed that his model can learn what causes his weight swings given the low resolution delta-weight data he collects.<p>The author uses vowpal-wabbit to train his regression model. Anybody know what learning algorithm it uses (eg random forest?)

Remarkable work. I am really pleased about the contribution of &quot;sleep&quot; in the whole weight loss experience. I have reached some similar anecdotal conclusions; I bet this is similarly not surprising for many persons.<p>I am not entirely sure sleep contributes only as &quot;a fasting period&quot;. Sleep also means we are relaxed. All the other times of the day (when we are awake) we are relatively stressed, meaning more stress hormones (ie cortisol) which are known to be contributing to weight gain.

One thing I&#x27;ve never been able to get a clear answer on, is when you &quot;lose&quot; fat, how long does it take for the number of fat cells to go down? As I understand it, at first fat cells just deflate (not the right word) are will easily plump up again and that&#x27;s one reason why it&#x27;s hard to keep weight off. What&#x27;s involved in actually ridding the body of the extra cells (outside of mechanical means)?

When I ditch the carbs and eliminate grain from my diet, there&#x27;s no denying that I look better and feel better. I&#x27;ve cycled on and off several times now and there&#x27;s no way to get around it: The carbs and grain have to go and they have to go forever.<p>If you can eat them, no problem. However, there&#x27;s many of us that can&#x27;t and we&#x27;re going to talk about how to operate with that as baseline.

I&#x27;d love to see something like this applied to the goal of gaining muscle. I&#x27;ve been a twig my whole life. In college, I gained 20 lbs of &quot;noob gains&quot; and then tapered off severely. I&#x27;ve maintained that weight, but can&#x27;t gain more with any reasonable effort.<p>Dear ddv,<p>You&#x27;ve got a potential million+ dollar business in the works. In fact, I&#x27;d quit my job to be a programmer on your team.

I just started my keto diet about 2 weeks ago and I feel great. Did have one rough night of &quot;keto flu&quot; but then I started supplementing with minerals and more water. I&#x27;m super low carb right now. Funny thing is to get (about 4 weeks ago) I would get a double big mac or a double quarter pounder but no drink and no fries and that was it till breakfast. That was fun.

Maybe your weight loss rate accelerated because you started watching what you eat more carefully, knowing that you want to provide the most sanitary input to your program. Anyway this is impressive for a n=1 study. Glad it worked for you.<p>Also, OP, what materials would you recommend for a machine learning newbie?
etangent将近 9 年前
One should be careful extrapolating this type of data to other individuals. For example, sleep on its own may not actually be the primary factor in weight-loss --- the weight gain during periods of lack of sleep may occur simply because you have a habit of snacking while staying up late.<p>That said, awesome work.

I think this shows how various factors correlates with the amount of water&#x2F;food still in the digestive system.<p>I&#x27;m not surprised that for example sleeping longer would make you having less water in your body.<p>Most foods that gave &quot;weight loss&quot; were high energy foods that have lower mass per calorie.

I&#x27;ve tried keto a couple times in the past, but struggled with serious acid reflux &#x2F; heartburn from having to digest so much fat all the time. Any one else struggle with this and find a way to incorporate keto without negative digestive consequences?

The observation that &quot;no breakfast&quot; is #1 way to lose weight by extending fasting period that includes sleep is pretty astonishing. Everything I have read says no breakfast is one of the contributors to weight gain.

I&#x27;ve had weight graphs like that and the trouble always is that if you plot further instead of it being a flat line at a constant weight it bounces back up again. It&#x27;s maintaining that&#x27;s the hard part.

In males, over time testosterone decreases which causes muscle mass to decrease. Building up the large muscles through resistant exercise or any exercise (eg, gluteus maximus -- thigh) increases the muscle mass. Increased muscle mass increases the basic metabolic rate (BMR) which is the number of calories consumed even while at rest, even while sleeping.

Yeah. I has been downvoted into oblivion by saying almost the same things without any machine learning, just by observing eating habits and traditions of &quot;village folks&quot; in Nepal, India, Tibet and Sri Lanka where I have spent last few years.<p>The message was that traditional (evolved according to local food sources and seasons) unprocessed foods of Asian tribes is the most natural and healthy. Economic and habitat selection pressures implicitly works the same way as machine learning, for hundreds of years.<p>Visit any rural area and try simple folk&#x27;s foods. They will be way healthier that any processed crap. The similar patterns could be notices really quickly.

A couple a years ago I did keto for 8 months. During that time I lost 31 kg. While this diet was amazing for losing weight it really affected my concentration negatively, to the point where I was forced to drop the diet because it was simply interfering with my performance at work. It&#x27;s a real shame though, as I&#x27;ve never been able to find a diet as easy and effective since.

Ketosis is the greatest thing to ever happen to me. It has been life-changing for myself and many of my closest friends. I lost over 200lbs doing keto and it was one of the easiest, most ennjoyable things I have ever done in my life.<p>Keto is absolutely amazing and life-changing. I encourage everyone to try it.
