Adipocyte, Musculus, and Rattus norvegicus

Meet the white fat cell (as opposed to the brown one).
Their main responsibilities are as energy storage, insulation, and cushion. There is fixed amount of fat cells in the human body --or so I've been told. With the increase of the lipid content (shown as the yellow part inside each cell), the adipose ultimately grows bigger in size. Weight gain usually is attributed to the increasing size of individual cell.

Meet the skeletal muscle cells.
They are responsible in the moving mechanism of the bones. As such, they are the targeted cells on body building activities.
So clearly, these two cells are of different types. Beware yourself to the notion of fats turn into muscles and vice versa.

Last night, I went to sleep pondering the ways to selectively reducing the size of the fat cells as opposed to the size of the muscle cells in my body. While all these times, billion dollar industry flourishes in the open, dedicating itself to the affair which includes variety of diets, exercises program, combinations of diet and exercise, chemicals, physical therapy, etc.

The trigger point being this article that ensued hilarity just from reading its abstract. In the end, it feels as if I was alienating you peeps who work with life objects. Here it is without further ado:
Adult male BHE rats were fed diets containing 15% of either corn oil (CO) or medium chain triglycerides (MCT) as the dietary source of fat. Further, rats were allowed to remain sedentary or were forced to exercise by swimming for 1 hour daily, for 3 weeks, followed by swimming for 2 hours daily for 3 weeks. The exercise for 3 weeks caused significant reductions in average body weight gains. After 6 weeks of exercise the lipid content of the adipose cells was reduced by about 50%. Fat cell numbers were not changed by either fat source or exercise, but fat cell size was significantly reduced after swimming daily for 6 weeks.
What makes it hilarious to me:
  • The lab rats being forced to swim. How was it administered? And exactly how intense was the swimming?
  • The rats were put on a serious daily swimming schedule that was fixed down to the amount of hour and the total time.
Without further adieu, the rats did it in respond to their (forced) binge eating, which in retrospect, is much like us and our eating habit. So there, with a pact of dedication, we human too can succeed in our journey for a fitter bod.

I forgot where exactly each picture was from. Google Image, for sure.
