I need some help to figure out what kind of diet or eating regimen I should follow. As weird as it may sound, the more I try to follow convention "healthy eating" rules, the worse I feel. Expecially when I try to eat light or whole food, they just don't hold me and worsen my brain fog. I seem to need heavy foods like casseroles, mac and cheese, avocado, sausages, pasta. For example fish doesn't hold me and while I try to eat some cod or salmon for health, I never feel good after eating it. At the same time I'm kind of glucose intolerant and get glucose rush from heavy carb meal and even a weird vinegary-sour taste in the mouth that last for hours after eating something carb heavy. At the same time low-carb has the worst effect on me, whenever I try to just eat meat and vegetables and even tried to whole adaptation period once but after three weeks I collapsed with a glucose reading, at the hospital, of 25 mg/dl. Although all the tests for wheat or lactor intolerance where negative, I have tried to go that route but that made me feel the worst ever, considering I tolerate white pasta more than whole grains in soups or whole wheat bread and that a piece of cheese is what often helps me not to collapse at afternoon. Even food in my case has a day-after effect, like a glucose rush one day means feeling glucose depleted the next, what sometimes makes me feel good at dinner has a terrible after effect the next morning. There are foods I don't tolerate that makes me feel like I'm drunk or something including oatmeal, bananas, ice-cream, excessive animal fats (like fresh bacon or butter or cream; but I have no problem with olive oil) protein powders, soups, brown rice. Still sometimes what agrees or doesn't with me is unpredictable and what I tolerate one day I don't the next. As for me I'm a young male and although I haven't gained lot of weight with CFS, my abdomen has. So I have actually very skinny legs, mildly skinny arms and a protuding belly. Is there anyone with similar issues and body type that can explain what's going on and share few tips or nutritional approaches?
