eli5: why is gaining weight so easy but losing weight so hard
In: 61
Not for everyone gaining weight is easy, alot of people find it hard to gain weight but easy to loose
Simply put, our bodies weren’t built to live during times where calories are as easily and densely accessible as they are now.
Some animals (like rodents) burn through calories extremely quickly and need to eat constantly, some animals (like seals and bears) store fat extremely efficiently because being chonky is essential for their survival. Physiologically, we’re somewhere in the middle, storing some fat but also regularly burning it off when we exercise.
But because we suddenly have more food, and more densely caloric food, now more than ever before, our system is out of date – we should be burning calories more like that first category of animals if we want to keep the weight off, but evolution takes a lot longer to develop than farming technology.
Because generally western lifestyle promotes unhealthy habits that accumulate over time. You can’t fix a bad lifestyle with a timed diet.
It’s not. You eat too much you get fat. You don’t eat you get thin.
Only difference is overindulgence is fun. Hunger isn’t so it feels hard.
You dont get fat or thin overnight. It’s a months long process.
I xan put on a few pounds in a few weeks by eating chocolate every night. And I can lose it just as fast going on a strict intermittent fasting diet. Which one is going to be more enjoyable.
It’s a biological advantage to keep fat and store as much food as possible as fat. Our human bodies evolved in an environment where food was not guaranteed. Going days without food. Storing excess calories as fat lets us burn that later for calories when needed. But our bodies use fat very efficiently because at that point the body thinks you are lacking food and therefore needs to use the fat you have for a long time.
