    Obesity is number one cause for death and many diseases like cancer, heart disease, type 2 diabetes, , it become a major worldwide threat, one of the keys to eleminate the excess body fat is DIET what to eat, when and how much.
    So i like to explain for you one of this diets : The Atkins Diet.
    Atkin Diet is low carb plan created by Dr. Robert Coleman Atkins in 1972, the Atkins diet restricts carbs while emphasizing protein and fats, it can change your eating habits to help you lose weight and maintain a healthy life style, the main thing is to focus on eating the right balance of carbs, protein and fats, controlling the amount of carbs of course, the Atkins Diet doesn't require calorie counting or portion control, It does require you to track your carbs, though. It uses a system called net carbs, which is the total carbohydrate content of an item minus its fiber content. For example, a half-cup of raw broccoli has 2.3 grams of total carbs and 1.3 grams of fiber, putting its net carb value at 1 gram.
    The Atkins Diet says its approach to carbs will burn off your body's fat stores, regulate your blood sugar and help you achieve optimal health, while not leaving you feeling hungry or deprived. Once you're at your goal weight, the Atkins Diet also says it will help you identify your personal carbohydrate tolerance — the number of grams of net carbs you can eat each day without gaining or losing weight.

    Back in the 80s people used to get fat through processed and refined simple carbohydrates,that had a huge impact on insulin spike.As a result lipogenesis-fat storage in adipose tissue took place,via the enzyme LPL from pancreas.Dr.Atkins and Dr.Mauro Dipasquale modified the low carb ketogenic diets in order to prevent the increase in insulin resistance,the diabetes type 2 (non insulin dependent),the hyperlipidemia and the metabolic syndrome.Insulin is a metabolic hormone that turns into anabolic for bodybuilders,but it is also responsible for inflamatory conditions (obesity is an inflamatory process).The low carb-ketogenic diets have some benefits for the metabolism:1) they lower the insulin resistance,hence satiety occurs and glycemia idoes not exist.2)they shift use of fats as a main energy source,in the absence of carbohydrates.3) as soon as you get into the ketosis state,anti-catabolic products like HMB (metabolite of leucine) act as muscle sparing.However the disadvantages of a ketogenic diet is:1) increased cardiovascular risk in case SFA are consumed (palmitic,stearic).Instead UFA shall be consumed (DHA,EPA,ALA,ARA,CLA,GLA,OA,LA).2) Brains function is majorly affected since cerebral metabolism depends mostly on glucose (400gr/day).3) Muscle glycogen synthesis is inhibited (glycogen synthase enzyme) and muscle pumps do not exist.Moreover HIIT exercise can not be performed too.Anaerobic oxidation of glucose requires muscle glycogen and weight lifting along with sprints need muscle glycogen as a substrate for ATP-CP production.Ketogenic diets are dehydrating since muscle glycogen is formed by starch and water molecules.This is why in the first place acute weight reduction occurs,coming mainly from water and muscle glycogen.Ketosis is an acidic metabolic enviroment,where blood Ph drops (<7.35) and metabolic acidosis is a fact.As a result,hyperventilation from the respiratory system and the lungs will ensure that ellimination of CO2 will restore the acid-base balance in the blood.Ketosis is the perfect biochemical enviroment since lipogenic insulin is supressed,while lipolitic glycagon and HGH are increased.ALA could be useful ocassionaly during carb cycling every weekend or so,since it acts as an insulin mimicker.
