I have adhered to pretty much every diet under the sun that involves actual food. It is partly because I used to be a lot fatter than I am and partly because I like lifting weights and thus building muscle. What I have been able to glean from trying pretty much everything is that various diets have a plethora of different effects and the diets are mostly good for different things. Some are not much good at all, truth be told. These are my own experiences in short. Maybe you could state yours? Low carb/Keto Until recently, I followed a very strict ketogenic diet, meaning I ate mostly fat and protein, with very little carbohydrates. I cannot say that I will recommend the experience much, as it is bad for hard training performance as well as recovery. Even going lightly, I could not recover from hypertrophy weight training in a proper manner. Spiritually, it does not help much either to eat that much red meat and high fat dairy products. The pork is a great culprit in inflammation and the salt normally in every kind of meat is too much over time. It is however good for one thing, for a while, and that is dropping water weight. Beyond two weeks is pretty pointless unless you are fighting or preventing fibromyalgia, cancer or some other disease. Veganism This is a great way of fasting for spiritual purposes, in my opinion. The foods normally eaten on this diet, like beans and lentils, will cause bloating. It is also normally very heavy on carbohydrates and starch, which leads to ups and downs in blood sugar. Given that it generally lacks complete and bioavailable protein, vitamin b12, vitamin K and ideal omega-3 long chain fatty acids, it can be as hard on the system as the low carbing. Especially for physical fitness and strength. It does however offer great short term spiritual benefits which are well worth a faste. This is also something that I believe is best done for a short period of time in order to gain the benefits without losing too much of your muscle mass, which is otherwise inevitable for your average western white person. And yes, there are exceptions, notably africans and asians but also white people who seem to be able to build some muscle mass on it, with supplementation and likely anabolic steroids. Although it is never as good as virtually any other diet for that particular goal. Vegetarianism and pescetarianism This can be seen as a balanced diet, if done properly. If you add either eggs, fish or both, and perhaps a little dairy if you tolerate it, this can be a good "normal state of things". It allows adequate training provided you eat enough protein and carbohydrates. The fish and eggs are important for muscle gains due to the valine and fats found in eggs, the omega-3 in (non-farmed) fish and the naturally occurring creatine in the lean fish meats. If you include plenty of vegetables and fruits, it can be excessively rich in micronutrients, and can really only be rivaled in completeness by a few standard diets such as the mediterranean diet and paleo. I often refer to the pescetarian regimen as "the japanese balanced way" of eating. It gives a fair amount of spiritual benefit while it also provides the ability to maintain or develop a physique, done right. Avoiding red meats and processed foods, it is also a very good diet for healing yourself from inflammations. Inflammation is a very large problem with most people, who live on commercially grown meats that are high in the not-so-healthy omega-6 fatty acid. I will personally attest to this. This is also pretty much the easiest way to eat as a self-sufficient farmer and occasional fisherman. Paleo and mediterranean diet This is also a fairly balanced way of eating which lends itself to health. I personally currently adhere to a diet which is a lot like paleo but pescetarian instead of complete omnivore. Eating more red meat will lend itself to being concrete and practical. It will have lesser benefits creatively and spiritually than the above but better than the low carbing. Paleo and mediterranean diet is absolutely great for training, especially if you include and tolerate grains. It is conducive to muscle growth, isn't terribly inflammatory and it is much cleaner than an avaerage diet. Western standard diet Please avoid this. It is the worst cocktail of poison and terrible ratios to be found anywhere. The only thing it can be good for is doing a dirty bulk and because it tastes good. It has zero spiritual benefits and it is not optimal for training or working hard. Periodic or intermittent fasting This is not really about what you eat, per se. I often skip breakfast and take a late lunch, which often equates to 16 hours of faste per 24 hour period. It is not a rule, but it has its benefits. Besides making it easier to eat fewer calories, it makes you alert and clearheaded, makes you less prone to mood swings due to stabilized blood sugar, heightens your growth hormone levels slightly and so on. Spiritually, it is of course a good thing to stay hungry for a moderate amount of time. Ayurvedic diet This has plenty of benefits. Especially when combined with some of the above. I suggest looking into it, especially what Ayur Veda says about various foods, herbs and spices. It can help greatly with inflammation, which is the root cause of many different ailments. Alcohol Has some benefits of spiritual significance if done right (excessively and seldom), firstly when it comes to getting to know the true nature of someone and bonding. Secondly, it can help you break down the walls of your subconscious so that you start remembering bits and pieces of past lives, if you are far enough along. If you get plastered and start crying about Napoleon or something past, chances are you have things that are ready to be drawn out by regression. If used often, it will make you base, stupid and very concrete as opposed to spiritually alive. Like "normal people", who eat crap all week and drink most weekends. Never drink often. Also note that some alcohol sources are better than others.
