Yes, The basal metabolic rate of an average thirty years old man is probably between 2000kcal and 2500kcal. You most likely burn 350kcal a day due to your activity in addition to that. That’s still around 15%. Based on that I expect fluctuations of around 5% of your calories consumption between an active and a non active typical day (without exercising). That’s not massive but probably still noticeable.
