Buses in London - Operation. 1  Most local buses within London form a network managed by London Buses, an arm of Transport for London.
But today I had a brief chat with a personal trainer, and he told me that If I am eating 1200 calories a day and want to lose weight, I need to burn around 1700 calories A DAY, so should be in the gym 1-2 hours every day for an intense workout. Isnt that too extreme, having to spend 2 hours a day, 7 days a week just to lose 1 pound a week?
The standard figure thrown around by the fitness industry is a 500 calories a day deficit. This works out to a nice neat sum of 3500 calories a week (500 x 7) which just so happens to be how many calories it takes to burn 1 pound of fat off your body.
