When you lose weight, where does it go?
体重が減ると、それはどこへ行くのでしょうか？
Um, um, that's a really good question.
えっと、えっと、それは本当に良い質問ですね。
I lose in in the the sweat.
汗で減るんだよ。
Almost sweat more than loss.
減るというよりほとんど汗をかくんだ。
Just where the the weight becomes water.
体重が水になるところだよ。
A bit of sweat, but no, that's not the main contributor.
少しは汗もかくけど、いや、それが主な要因ではありません。
Definitely, it goes off in the form of gym fees.
間違いなく、ジムの会費という形で消えていきますよ。
Yeah, for sure.
ええ、間違いないね。
Your muscles.
筋肉だよ。
I want to say a better word, but if you if you definitely let's say, how is stuff leaving your body?
もっといい言葉で言いたいけど、もし、もし、確実に言えば、どうやって物が体から出ていくの？
Ah, parties.
ああ、排泄物ね。
That's that's a good way.
それはいい言い方だね。
Breathe.
呼吸です。
As you breathe, you inhale oxygen, but around three quarters of that oxygen you just breathe out again.
呼吸するとき、酸素を吸い込みますが、その酸素の約4分の3はそのまま吐き出されます。
The remaining quarter is replaced with carbon dioxide, and carbon dioxide is heavier than oxygen because each molecule contains a carbon atom.
残りの4分の1は二酸化炭素に置き換えられて吐き出されますが、二酸化炭素は各分子に炭素原子を含むため酸素より重いのです。
So every time you breathe out, you're exhaling carbon and getting a teeny tiny bit lighter by roughly a hundredth of a gram with each breath.
つまり息を吐くたびに炭素を吐き出していて、一呼吸ごとに約100分の1グラムずつほんのわずかに軽くなっているのです。
Eighty-four percent of the lost fat you breathe out as carbon dioxide.
失われた脂肪の84パーセントは二酸化炭素として吐き出されます。
Wow, actually, actually, that's the quickest way to question was taken from our new trivia game, Elements of Truth, which you can pre-order via the Elements of Truth website.
わあ、実は、実は、それが一番早い方法です。この質問は私たちの新しいトリビアゲーム『Elements of Truth』から取られたもので、Elements of Truthのウェブサイトから予約注文できます。
