I haven't felt the heavy head, and agree an education is never wasted... A bit concerned about the diet however. Avoiding certain foods we know aren't good for us, fried food, pre-processed foods, high fat, high sugar all the junk foods, sure it's sensible. If you want to cut out gluten too, it shouldn't hurt.

But eating only twice a day and fasting? Doesn't sound healthy at all. If you think of the nomads we came from, humans were meant to have varied diets and pretty much graze, never bloating from over eating (as we're prone to do today) and never suffering through hunger pangs.

Even if you 'feel better' now there could be issues down the road and is likely only a result of it also cutting out some of the foods that are bad for you giving you a temporary diet high.

I would keep any diet sensible, make sure your able to get all of your nutrients from the food you eat not a supplement unless you are naturally deficient in something. Make sure it provides adequate calories (drinking a shake to make them up isn't the answer) and keep in mind the average person needs at least 1200 calories a day if they're only laying on the couch.

An occasional fast isn't going to kill you, it's a long held practice in many othodox religions even, and there's a multitude of medical tests that require some fasting, and with me at least there are days that the ms imposes its own day of fasting when the energy to eat is just too much.

I'm not familiar with the diet you mentioned, but I would steer clear of any diet that doesn't offer a variety of foods or is too dependent on one type of food to meet the caloric or nutrient requirements, no matter how many people praise it or how reliable the source appears.

If you want to eat healthier by all means please do, don't know what your diet was like before, but you can't really go wrong with fresh food, frequent meals, keep the fats, oils and sugars low but never cut anything out completely. Our bodies still need some sat. Fat. We still need cholesterol, sugar and fat and even quite a lot of calories. Sweep the kitchen floor one day and the average person is up to 1300 calories for the day, go food shopping? 1600 calories... Live in a cold region 2000 just to sleep through the day.

Sorry if I sound prejudice against diets, not all are bad but there are so many that are and are down right dangerous to follow. So I made my own rules to go by, variety, nutrients, doesn't run to a caloric deficiency, or randomly cut foods without plausible explanation, (tomatoes suffer from identity disorder, while true is not a good enough reason to never eat them) or forcing one to eat certain foods again without plausible explanation (apples have been shown to increase pulmonary function in patients with COPD, sounds false but is true one of the chemicals in the skin is what does it, I forgot which one) if the diet meets the above I'll give it a shot, if not I wouldn't try it.
