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?
On their own, calorie counts don't mean very much, so estimate the number of calories you burn during the day for perspective. Harvard Medical School recommends that moderately active people multiply their weight by 15 to calculate daily burn. So at 150 pounds, you likely burn 2,250 calories per day. You lose a pound for every 3,500 calories that you burn and don't replace with food; likewise, you gain a pound for every 3,500 calories that you consume but don't burn.
