OBESITY AND ITS PREVENTION

OBESITY
Adverse effect on body due to excess accumulation of body fat which lead to reduce the life expectancy of individual subject also have major health manifestations this is classified as the obesity.Or more precisely if your body mass index (BMI) is greater than 30.0 you are suppose to be obese.Body mass index(BMI) can be calculated by mass(kg)/(height in meter)2 . On the basis of BM index i can able to distinguish between obesity ,overweight and normal or under weight.
  • If BMI is <18.5 it mean underweight 
  • If BMI is in between 18.5-24.9 normal
  • If BMI is in between 25.0-29.9 overweight
  • If BMI is in between  30.0-34.9 class 1 obesity      
  •  If BMI is in between  35.0-39.9 class 2 obesity     
  •  If BMI is greater or equal to 40.0 than class 3 obesity   
Now you are able to self categorized.  
Another criteria which can classify the Abdominal obesity is Waist/Hip ratio 
  • If waist/hip ratio is above than 0.9(males) ,0.85(females) OR BMI is more than 30.0
  • Abdominal obesity is of two types first one is "Apple shape" in which excess fat is around belly which is more dangerous than the "Pear shape" in which excess fat is around the hip (male with waste 40 inch in female 39 inch consider obese).Why obesity is important to know because due to this in USA 111,909-365,000 deaths per year and in Europe this amount is 1 million deaths per year.  




MECHANISM 
Deposition of fat to various organ of body is dependent onto the bad guy ;low density lipoprotein (LDL) because dietary fat from gut is delivered to liver from there cholesterol (the fat) taken up by LDL and delivered it toward the periphery(toward body organs) and deposited there ,it mean when ever the LDL level is high more fat is deposited onto body.Counterpart of LDL is high density lipoprotein (HDL) the good guy which deliver the peripheral fat toward liver for metabolism and excretion hence reduction in fat content of body.In nut shell raised of HDL is good but LDL is alarm to you.[recommended level of total cholesterol(hdl,ldl and 20% of total TAG) is less than 200 mg/dl ,borderline is 200 to 239 mg/dl ,greater than 240 is high].




TYPES OF DIETARY FATS
