Genuinely how do you not get fat during busy season

I’m a first year associate. I have about a 45 min commute to and from the office so I lose time there too. Last week, in tax, we needed 50 hours. I only went to the gym twice last week. This week and until 4/15 we have to hit 60 hours a week. Genuinely how do yall have time for the gym or how do you prevent getting fat these next 3 months. Im already committed to eliminating snacks and sugary drinks but im worried about not having the energy to commit to the gym. Any tips?😭
