calories from waiter job

[tenakakhan1989]

Hi
I work as a waiter and i find on average im fast walking with plates etc for 6-8 hours 6 days a week.

i found a site where it gave values for various exercise in terms on calorie usage, and it came out that in 6 hours of this at my bodyweight im burning over a 1000 calories. but this cant be right?

so with walking, how best should i factor this into my diet, so that im eating enough.

i still train weight 4 x week, and 2 low intense cardio, 2 HIIT per week

im 75kg, or about 170lbs, 20 years old, 5,10 height
about 15% body fat

thanks in advance
