Fat Lot

Wow, this is all just false or limitedly true in a very, very small set of circumstances.

Human bodies just don’t work like that. They simply do not. Muscles don’t even start being broken down until at least 24 hours into a complete fast, not the moment you get hungry. Frankly, that whole post is fucking moronic.

Then, about 2-3 days after the body begins taking nutrients from muscle, it slows this down and goes into ketosis.

By the way, your body primarily breaks down muscle to obtain glucose, so if you drink something with glucose even if fasting otherwise, your body won’t go after muscle all that much and will instead tend to continue to burn fat.

In addition (and I am going to link to a summary here, though I have read many of the studies) there is pretty good evidence that intermittent fasting is beneficial to your health, likely because it mimics the evolutionary environment of most of human history.

Why do Tumblr people believe that if you are hungry for more than a few minutes, you go into starvation mode (which isn’t even really a thing), and that if you don’t eat to absolute capacity at every meal you are at risk of the dreaded starvation mode?

There is literally nothing correct in that Tumblr bit I linked. Also, you do not have to starve yourself to lose weight (unless you are using the Tumblr definition, I guess). This going to the extremes is why I think a lot of Americans have issues losing and keeping off weight.

A minor calorie deficit a few hundred calories a day means you’ll lose 30+ pounds in a year.
