Kaleo Diet 

A combination of the Ketogenic, or Keto, diet and the Paleo diet. Many people have adopted the Paleo diet (eating like our hunter-gather ancestors) which means no grains, legumes, processed foods, sugar, etc. Now more and more people have switched to the Keto diet (a high fat and very low carb diet which forces the body to burn fats rather than carbs since we normally burn carbs for fuel, but if there is very little in the diet, the body will burn the fat for fuel through a process called ketosis). You can continue to eat the like a cave man but adapt it to a percentage of fats, protein and carbs that turn your body into a fat burning machine and you have the Kaleo diet.

The Kaleo diet is a combination of both the Paleo diet (no grains, legumes, processed foods, sugar, etc) and ketogenic diet (a high fat and very low carb diet which forces the body to burn fats rather than carbs).

Pythagorean Diet 

When math geeks tell others that they eat or use zero animal products like honey, seafood, egg and diary, fish, and meat—named after Pythagoras, the Greek vegetarian mathematician-turned-numerologist.

Alt-right Trumpists and QAnonists never fail to remind each other that Adolf Hitler adhered strictly to a Pythagorean diet during his years-old tyrannical rule, unlike their Insurrectionist-in-Chief boss, who occasionally craves for junk food.
