How does Sakamoto lose weight so fast in Sakamoto Days?

Sakamoto, the best hitman out there, fell in love, retired from the blood-soaked world of assassination, and became a doting father we all love. 

But even though he swapped his sleek suits for an apron at his family-run convenience store, trouble seems to follow him wherever he goes, and once a bounty is set on his head, we are taken for a wild ride.

In this article, we will hypothesize how Sakamoto loses weight so fast. Is it an elixir he ingests? Or some ability? 

What is the secret to Sakamoto’s weight loss?

The secret to Sakamoto’s weight loss is his superhuman ability to burn all his fat away for energy, as calories are energy. Since he already carries a hefty amount, the process quickly aids him. 

Underneath his layers of fat, he is a lean man; after all, he was a former member of the Japanese Association of Assassins’ Order. 

His years as an assassin have strengthened his body more than the average human’s. Since he doesn’t expend his saved calories like at the grocery store, he stores them as fat. 

He easily converts all that stored fat into the energy needed to face his enemies and protect his family when under pressure.

Some fans have hypothesized that this could be like his “second Form,” the way All Might goes from being a sickle to a muscly pickle who can crush his enemies. 

Is there any side effect of his sudden weight loss?

Granny Miya, a holistic healer, revealed that it is harmful for Sakamoto to undergo such sudden weight loss anytime he is in a grave situation, as it weakens him; for a healthy body, he should be able to fight with the same intensity as in his normal body.

Since Granny revealed this in chapter 47 of the manga, Sakamoto refrained from reverting to his skinny form and tried to put up with his enemies in his chunky body. 

However, in chapter 91, he had to resort to his skinny form for strength to defeat Kanaguri. This shows that despite being the topmost assassin, he still has a long way to go to become a stronger fighter by adapting to his normal body, or else he will be weakened every time he reverts, so his weight loss is like a double-edged sword.
