I’ve read that there are limits to how much weight you can lose per week, no matter how much you restrict your caloric intake. Beyond a certain point, your body senses the deficiency and decreases your metabolism. If a person could restrict calories AND receive leptin injections, they could lose weight faster. (note, I am thinking about this in terms of helping the morbidly obese in dire circumstances.)</text><parent_chain></parent_chain></comment><story><title>The brain has a ‘low-power mode’ that blunts our senses</title><url>https://www.quantamagazine.org/the-brain-has-a-low-power-mode-that-blunts-our-senses-20220614/</url></story>
