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?
They body isn't so automatic. If you burn 250 calories during a workout, and eat a 500 calorie dinner. That's 250 calories more than you just burned, but only in a limited time frame. In the greater context, if you're burning around 3000 calories a day, and eating 2500 total..that's still a net loss of 500 calories.
