Even our Pets are More Obese Now than 30 years ago - C.Dagnelli
With obesity rates on the rise, many people are concerned about their caloric intake. According to a government survey in 2000, the average American man consumes 2,666 calories a day and the average woman about 1,877. These numbers do not correspond to the obesity rates.
Recomended Calories
The USDA food pyramid recommends consuming between 2,000 and 3000 calories a day for men, and 1600 to 2400 calories a day for women. This number varies based on the person's weight and activity level. Technically, people become overweight when they consume more calories than they expend. This of course can happen silently, where a person is active, eats the recommended food and calories on the pyramid but their body is burning at a much lower rate than it should.
The average American woman weighs 165 lbs and needs about 1,600 calories to keep her organs functioning if she were in bed all day. Active women need to consume an additional 400 calories to have enough energy for their activities, and athletic people sometimes consume several thousand more calories.
How Many Calories You Should Eat.
A moderately active person should add 400 calories to his basal metabolism to maintain weight. If you are someone attempting to lose weight you would not eat these additional calories so you can count the amount of your activity and exercise as your calorie deficit. Once you accumulate a 3,500 calorie deficit, meaning you have burned 3,500 more calories than you have eaten, you would have lost one pound.
Why You May be Over Weight.
Science is now making connections with obesity beyond the conventional. You have been told for years you need to move more, eat less and people are doing it but the weight remains. The EPA has been studying endocrine disruptors, also known as obesogens because of the dramatic increase in childhood obesity. These are chemicals which make their way into our food and environment and are interfering with the livers normal functioning. They force the liver to by-pass the steps that normally occur when you metabolize food. A healthy liver converts the food to energy, fueling hormones, glands, then fat cells. Obesogens and unhealthy livers are skipping the middle two steps and going right to fat cells. This leaves you bloated, lacking essential hormones and with extra fat.
Chemically speaking, this skipping of steps makes the liver insulin resistant from the pancreas dumping extra insulin throughout the body. Too much insulin makes a person diabetic and overweight. The added bonus, now the liver is not making enough leptin, and without it, you are always hungry.
Known Obesogens
Some known obesogens are in non-stick pans, high-fructose corn syrup (no it is not the same as sugar, your body DOES know the difference)hormones in non-natural meat, and dairy products. Meats specifically wrapped in plastic and some plastic bottles numbered 3 and 7 on the bottom also have Bisphenol-A (BPA) is a synthetic estrogen. Vinly products, some air freshners and plain 'ol tap water that has pesticide levels.
