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?
Therefore, you have to burn 3,500 calories more than you take in to lose one pound. For example, if you cut 500 calories from your diet every day, you would lose about one pound a week. Or, if you are physically active, you can eat 250 calories less every day and burn 250 calories per day with your workout.
