Number 19 exercise and hunger

This is a review of a review of an article in Nutrients, 2021:13(2) 347.  If you exercise, you get hungry.  If you wait a little , you are not quite as hungry.  About 40% of the world is fat.  People try to lose this fat as most do not like it much.  The most common diet is to eat less and exercise more.  People are smart enough to figure this out on their own, but it is also the most common diet advised by your health care provider.  Obviously this diet does not work as the incidence of obesity continues to rise. Of course you could say how come this doesn't work.  I took physics and this has to work or thermodynamics was wrong.  This paper told us why.  You get hungry.  This is the reason this fails.  Hunger is a result of your body demanding energy.  It would be nice if we could get this energy without eating.  Then we could really lose weight. I know some of you have seen the biggest loser where people eat less and exercise 8 hours a day.  If you do this, you will lose weight.  Of course almost all of these people gained all the weight back within a couple years.  Most people have a job and cannot exercise that much.  They also get injured.  They also just can't stay on the eating less part because they get hungry. Go to kellygregg.com and I discuss this at length.  If you want to lose fat, the most effective diet is the ketogenic diet.  Even if you want to exercise more, the ketogenic diet does not limit your calories., and thus provides your body with energy and decreases hunger. This is a temporary diet and you then must go on the maintenance diet to keep from getting fat again.  I really don't care if you exercise or not, you still will lose weight. Exercise does increase you work capacity and decreases the risk of injury in daily life, but it is not important in losing weight. You have to read the book.
