Is Intermittent Fasting a Solution to Lose Weight Fast?    

       Since obesity and over-weight (you need a noun, you used an adjective) have been a critical health issue for a large number of people and considered the most predictable cause of early death, methods for lose weight (generally, with lots of exceptions, of course, we use to+verb, for + noun) have been adopted, ____ as the ‘Intermittent Fasting’ method. (no need to capitalize intermittent fasting)
       The ‘Intermittent Fasting’ method consists of staying 16 hours without eating per day, but drinking water normally, commonly achievable by having no breakfast. It does not change what, when and how much you eat, but your pattern of eating, without reducing calorie intake. Tough, it is not a diet and it requires less behaviour change.
This method triggers the so-called ‘body fasted stage’ that is achieved after 8 to 12 hours without eating. In opposition to the no 'fasted stage', the insulin hormone level is very low while the glucagon hormone level is high, causing fat burning while the muscles mass is kept.
       To better understand this process, it is important to know that the insulin hormone level increase (third person singular) when we eat to store energy in our bodies in the form of fat and glycogen. It kept (simple present) its level high during 8 to 12 hours after eating and it prevents the reduction of the body fat. After this span, the glucagon hormone level increase, which has the opposite function than insulin, burning the fat and glycogen stored to supply energy to the body, what causes fat and weight loss.
       The main obstacles reported by practitioners of ‘Intermittent Fasting’ are the initial fear of being hungry and the hungry (noun, not adjective) felt in the first 4 days during the hour of the day that a meal has been cut off. Although, these obstacles seem simpler and easier to overcome compared to those of a conventional diet, added to the fact that the feast can be done at alternate days or one time a week and still produce good results.

Beautiful work, Cleverson! You write really well! I've been a practitioner of this way of eating ever since I remember skipping lunch because the bread my parents gave me was different from the bread the kids were eating (having moved to Canada from Poland, I didn't want to stand out but be like the other kids). Of course with time, your body gets used to it. I recommend it highly! We stuff our faces too often and we can afford to feel some hunger pains, no? What do you think? What has been your experience?
