Before the pandemic, I usually got up to make coffee, to ask for help or to make consensus with my fellow coworkers (other devs or even UX people, a few stairs away). I usually walked from work from time to time to clear up my mind. Now I barely move. I live in a small apartment. The fridge is 3 meters away from me.
Back then, I could somehow manage my weight by applying some casual restrictions, like eating fewer carbs and eat mostly lean cuts of meat. Now I need to apply some zen monk level of self control if I want to not gain more weight. And losing it is terribly hard.
