Obese Men & Women Lie About Their Diet

Today's brief is not politically correct. So if you are easily offended, press the page down button.

Most overweight people around the world are carrying their extra pounds because they eat too much and exercise too little, not because of "bad genetics".

The latest research study even shows that overweight folks are lying to themselves about their diet.

Researchers from the US Department of Agriculture had 524 men and women undergo a 2-week study. All they had to do was estimate how many calories they ate each day. This number was compared to their actual calorie intake, as determined by a proven scientific method.

Reference:
American Journal of Clinical Nutrition, Vol. 88, No. 2, 324-332, August 2008
The US Department of Agriculture Automated Multiple-Pass Method reduces bias in the collection of energy intakes.

The results were shocking. On average, the subjects underreported calorie intake by 11% each day.

That means if they thought they were eating 2000 calories, they were really eating 2200 calories. If you do that for 18 days, you'll have gained a pound of fat by overeating 3600 calories (a pound of fat consiste of 3500 calories).

But here's the bad news. Folks who had a normal Body Mass Index (BMI), only under-reported their intake by 3%. That means that overweight folks under-reported their food intake by much more than 11%.

So overweight folks are often lying to themselves (and their trainers!) when admitting how much food they eat each day. As a result, it's no wonder they are overweight.

To stop the lies, you need to start keeping track of all the food you eat. At each meal and snack, write down on a piece of paper everything you eat - including each handful of grapes, chips, etc., and all the leftover food you eat from your children's plates.

Compare this to how many calories you should be eating, as outlined in these Fat Burning Meal Plans

You can also use a site like Fitday.com to track your calorie intake.

fat people always lie about their food intake. My obese friends complain that they "only pick" at food and usually "forget" or are "too busy" to eat. But if you spend time with them you see that they actually eat all day and what they eat is c-r-a-p. It probably is some weird subconscious defense mechanism to keep them from having to take responsibility for weighing 300 pounds. It feels better to blame it on something else.
