Fat loss science | Effect of weight loss on human body and brain

What losing weight actually does to your body and brain

During the first week, you may find it easy to lose weight by simply switching to a healthier diet.


But as your metabolism adjusts you won’t burn as many calories as you used to.

So, losing additional weight will become harder making matters worse.


As the fat melts away you’ll start to experience an increase and appetite.


After meal fat cells release a hormone called “leptin” into the bloodstream.

This surge in leptin level signals to your brain that you’re full and should stop eating.

But with less overall fat, people who lose weight show a measurable dip in leptin.


Brain scans of obese patients who had lost 10% of their body weight reveal less leptin leads to increased activity and regions of the brain that controls our desire to eat.

The end result isn’t just an increased appetite but an even stronger urge to eat fatty, high-calorie foods.

 because your brain is trying to restore the body’s leptin levels to normal.


However, finding that early impulse to gorge on pizza and doughnuts is worth it in the long run.


Besides the decreased risk of :

  • 1) Heart disease.
  • 2) Hypertension.
  • 3) High cholesterol.
  • 4) Type 2  diabetes.
 Scientists studying overweight people discovered that losing just one pound of body weight reduces four pounds of pressure on knee joints.


Losing excess  weight also reduces,
 the strain on the blood vessels increases blood flow to the brain and boosts overall brain function.
Several studies have shown that people  who underwent weight-loss surgery  saw an improvement in :
  • 1) Memory
  • 2) Concentration
  • 3) Problem-solving skills
In as soon as three months.
Plus brain  scans indicate that people who lost  weight and kept it off for nine months,
they  reacted differently when shown images of high-calorie foods  than before they lost  the weight

The brain regions that process, reward, motivation, and the taste didn’t react too strongly.
Whereas the areas that promote overall self-control had to boost inactivity.
So, long story short, fighting those cravings early on might make them easier to control later.
 Losing weight can get easier with practice.
