MRI between a 250 lb woman and a 120 lb woman

In this case you could really have an entire thin person inside you with room to spare.  The above image is a full-body MRI of two women, one weighing 250 lbs (113.3 kg) and the other 125 lbs (56.6 kg.)

The colors  seen in the image represent the following:  Red=Muscles, Yellow=Fat, Bones=White and Organs=Black.

Looking at the toll obesity takes on the body from head to toe, I draw your attention first to the neck region.  Excess pressure caused by neck fat will result in headaches, snoring and sleep apnea, with by itself has a host of side-effects including memory problems, fatigue, breathing difficulties,depression, leg swelling and hypertension.

Forgetting the clear case of “jiggly arm-itis” for a second, I draw your attention to the black sacs in the middle of the chest.  Those are the lungs.  Although a size comparison shows them to be fairly even, the subject on the lefts increased obesity makes it harder to breath at night since fat will push its way Northwards towards the lungs.

I said forget about the “jiggly arm-itis” for a second…the increased layers of arm fat will increase the load on the shoulder joint, which is basically a shallow ball and socket joint that is already prone to injury.

Taking a step back…you will note that the bones of both subjects are similar in size despite the large weight differential.  So much for the “I’m not fat, I’m big boned!” excuse.   Dinosaurs had big bones.

Note that the subject on the left has fat forming around her organs, which is known as visceral fat, as well as having an enlarged heart.

Visceral fat just doesn’t sound nasty…it is nasty.  Visceral fat produces chemicals that have been linked to several forms of cancer and is directly linked to heart disease.

At a minimum, the enlarged heart will make breathing more difficult and does not pump properly.

The hip joints, knees and ankles are under quite a bit more strain on the obese subject.   Compare the knee and ankle joints of the two subjects and note the effect the excess weight has on the lower limbs.

For every pound of excess weight lost, there is a 3-5 lb reduction of pressure on the knees.  Taking the low figure, a loss of 10 lbs would equate to 30 lbs of pressure removed per knee.  

The feet also take a beating from carrying excess weight and can lead to   Plantar Fasciitis and an altered walking gait, which in turn effects all joints and muscles north of the feet.

If this isn’t enough motivation enough to try and lose weight then I have no idea what is.
