You have basicaly three types of fat. Brown which is on kidneys and uder scapulas. This one creates heat. Underskin fat, which are stored calories and visceral fat on inner organs which is stored toxic waste (metabolic and drugs rezidues which couldn´t be removed because of lack of clean water in the morning, fiber, antioxidants or minerals).
How to cut underskin fat. That´s the easier part. Underskin fat is biochmically connected with pancreas measuring Your glycemia. If You eat carbs (Yeah, CARBS!!!) every hour and a half, You´ll have perfect glycemia. Perfect glycemia means no hunger and no need to store the calories in fat. Be very aware of low carb diet and nonsenses like fruit in the morning and just vegetables and proteins in the afternoon. Your body wouldn´t create energy from proteins You have eaten but from small proteins in blood - albumins. It has first to change them on blood sugar and than use. It´s very dirty source of energy and it takes hours for the liver to do it. The result is hunger, rezidues after those proteins which will be stored in the visceral fat and damaging epigenetics (Your body will prefer to keep from newly born cells those weak who need less calories)
So, easy spoken, You need carbs all day in small portions. Prefer high fiber sources like wholegrain rice and pasta and lentils. (Count about 3 grams of carbs per kilogram of weight and day)
You need enouhg proteins too (cca 1,7 gram per kilogram of weight) to have strong active tissues burning energy (muscles, inner organs and so on) In one portion You stomach can digest about 30grams of protein max, so You´ll need to have at least 7 portions of food per day.
And the visceral fat. That one is much more tough. Your body has three ways how to manage waste. Normally, waste soluble in water goes in urine and waste soluble in fat goes to feces. But, if there is too much waste and too low clean water income (less than 27 mililitres per kilogram of weight drunken till 4-6 hours after wake up) Your body can choose abnormal ways (skin oil, so acne will apear, agressive stinky sweat, green mucose when You cough and so on). The third way is most dangerous in long time period - creating visceral fat. The waste will be ,,enprisoned" in small fat capsule and stays in levr and around inner organs. It exhausts immunity, creates inflamation and press on the other organs, so they are insuficiently perfused.
How to get rid of that. First, drink enough water, till one month drink at least 27 ml of CLEAN WATER per kilogram of weight till 4-6 hours after wake up. It´s the time when the body clean itself. Remember, You can´t clean anything with soda, tea, coffee, juice or milk. Only clean water counts. Water provides transport of the waste outside of the body.
Then You need soluble fiber and antioxidants from rosemary and courcuma, vitamins C and E, and aminoacid arginine. They will help to destroy the waste.
Proteins are also needed because all enzymes, including those detoxicating, are based on proteins and You need to create enough of them.
Good luck and if You need further info, send me message, we´ll figure it out :-)
