It’s gonna vary a lot depending on your needs. I work at a desk and don’t exercise very often (to my shame!) so I find I eat very little. Eggs and bacon at lunch and a steak at dinner, occasionally something extra.

I’d say plan for a week and see how you feel energy-wise and you can then get a better estimate. If you’re only starting though your body is gonna need time to adapt, so it’s tricky to plan ahead! Good luck, it’s kind of life changing if you stick to it 😎
