Blame oh....I don't know....moe.

Don't lose that fat!! This is a PSA for big-boned people: gain more weight if you want to float. Drowning is your biggest threat. Keep that life preserver close, because if you're ripped, you're SINKING!!

There are some genetic conditions that cause the body to store fat more easily than the average person, plus a ton of conditions that do the same.

Gut biome also has a big impact!

So when you eat something the food gets broken down and your body figures out what to do with it based on a combination of many things, and the recommended diet is basically the average, with plenty of people at the extremes of hard to put on weight or easy to put on weight.

All of the different combinations of how an individual processes eneegy can technically be addressed through diet and exercise, although being different from the human baseline can make figuring out the right diet extremely hard, and it is far harder to lose the weight than it was to put on while figuring it out.
