The diet that you’ve never heard of
The diet that you’ve never heard of is the one that works best for you. Everyone is different and everyone responds to foods differently. To say that one diet is superior than another diet is wrong. There is no superior diet because each person’s body is different. Just because you had incredible results on one particular diet doesn’t mean that someone else will have the same results. One person may have a food intolerance while another person can eat it perfectly fine. Unless you have a medically diagnosed condition, a personal belief, or a religious belief then restricting an entire food group is probably not a good idea.
In my opinion for long term health and longevity you should eat a wide variety of minimally processed whole foods. Eat a lot of vegetables, fruits, protein, healthy fats, and carbs. You want these foods to be as minimally processed as much as possible. You want them to look as close to their original form as you can. A French fry does not look like a potato, go for the potato instead. A hot dog or sandwich meat does not look like beef, opt for steak instead. Most things in a bag, box, wrapper, or can is heavily processed. Eat and prepare whole foods as often as you can. If you can’t prepare your own foods, then look at meal delivery services. Make sure they provide you all of the ingredients and do your due diligence to make sure they are using whole natural foods with minimal ingredients.
Most supplements are pretty much useless and should be avoided. Your #1 goal is to eat real food first, if you are still deficient in a certain area then supplementing is acceptable. The majority of supplements on the market are marketing gimmicks that exploit your insecurities and get you to spend your money on them. You’re better off spending the money on higher quality food instead of supplements. You should always try to get all your macro nutrients and micro nutrients through real food first. If you still have a deficiency, then you can supplement.
