In direct response to 'Full', I also did some research for a time on detox diets followed by readjusting eating habits. I just want to say as simply as possible (without going into an in depth detail story) that I strongly believe that the food marketed to us today as consumers isn't 100% full of its nutrients. I myself and another close friend shop very specifically and selectively when it comes to food (something which is overlooked by many people who just go to the local grocery stores and buy whatever on the shelf). I am not knocking these stores or saying that this food is bad. I still eat food you can find in stores. But what I am also saying is that like your friend, a little extensive search on alternative food sources whether for the same types of food or something completely new, is beneficial. Personally I have researched plant based proteins which contain higher quantities of protein that meat sources alone! Me and my friend both research food almost daily looking for new and alternate sources. Protein is currently on our list as priority as some of the controversial studies of animal based proteins seem sensible. Although I do enjoy a good well done steak and I love chicken and fish too. I won't go into too much depth about animal based products/proteins but I will say this: you are what you eat.
Back to your friends study: I went on a short detoxification regime to accompany my reevaluation of food consumption and within a month and a half, my hair did show signs of slight thickening within that short period of time. As soon as I am in a position to redo that old regime I will reintroduce it to my current lifestyle and to my family because besides a mental/logical/psychological satisfaction of knowing what I am doing, on a deeper level within I feel it works. And on a physical level I see it works.
During my 'detoxification':
A big jug of blended fruit smoothies and root punches
Banana egg yolk, milk or
citrus fruits and berries blended with plain youghurt/cream or
Carrot, orange and pumpkin
Blended parsley/coriander boiled for 10mins to help clear out kidneys every day
Plenty of water to flush out the impurities in my system...
as well as 5 mile runs and quarter mile - 1 mile sprints to help sweat out impurities in my body and boost HGH release
It was a struggle for the first few months, but aside from the fact we had no choice as our place of employment wasn't paying us correctly (due to company being sold to a new organisation) we had to make do with such a minimal diet. But I began to feel great afterwards. My digestive system was a lot smoother (primarily because of the lack of heavy meats and increase on liquidised foods lol), my oily skin on my face cleared up and my scalp was looking healthier. However on the con side, I did feel a lot more tired due to the lack of vital nutrients.
Whilst living with my Asian work collegue their diet consisted of rice based foods (they were also vegetarians a lot of their foods would be replaced with vegetable substitutes for where meat would usually go).
I started to include coconut milk over cows milk
pineapple and mangos
fish/chicken for myself but unfortunately no steak was allowed in their home
All junk food and fast foods were cut out.
No processed foods, white sugars or refined carbs
Wholegrains were added
flax seeds, sunflower seeds, pumpkin seeds were introduced into my diet (after added these I noticed the scalp under my thinning crown was less shiny and clearer).
However now I can say that on upon retrospection I have learned there needs to be a healthy balance of all foods you eat for a healthy well being. Now I am able to eat more I am eating all my old favorite foods, however I don't eat fast food/junk foods at all and I do still keep up the liquidised/blended fruits/veg. I would recommend a detoxification addition to a persons diet, rather than a substitute for any amount of time, and to keep it regular. I have looked into the 'alkaline' based diet and I haven't yet put it into action. However I have consumed a large amount of lemons and other similar citrus fruits which are believed to have an alkaline affect on the body due to its residue left upon being used despite their original acidic pH.
Fad dieting is dangerous, and the misconception to a lot of them is the replacement idea. I believe dieting should be a modified version of your current diet: that is remove what you feel necessary and introduce what's necessary. But I am glad for your friend, and your message here has given me motivation to reintroduce this back into my diet at some point as my findings weren't just on a whim, but seem to be a consistent thing with at least 1 other person in the world so far.
I have taken a note of all the books mentioned in this thread and I will be checking them out shortly.
Thank you and Happy Sunday.
