If you are around 30 and around 6 foot, then at least 1800 a day.
Eating too little will just slow down your metabolism, making it harder to lose weight in the long term - not only that but once you go back to eating normal amounts you will just regain weight quickly.
It's best to cut it slowly & add some weight training.
I'm 27, 191 pounds, 5"11 & eat 1800 on off days & 2200 on training days losing about 2 pounds a week (3 days a week I'm doing weight lifting for 35mins a day).
Sorry, but I'm not weight training, nor joining a gym as id be bored senseless. you're giving me almost the opposite end of the spectrum figures wise to other advice I've been given.
I'm relatively sedantry day to day, and have a desk job, so my ONLY ACTIVITY is 45 mins of walking/jogging.
