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?
Depends how many calories you are eating! To lose one pound, you must burn off 3,500 more calories than you eat. So, if you eat 2,000 calories per day for 7 days, that's 14,000 calories per week. To lose a pound, you must do enough exercise to burn 17,500 calories per week.
