$50 per hour is not the most expensive...a friend of mine charges more & she's featured in some national magazines periodically...one of the main things to consider when trying to lose weight would be your diet. Working at two of the most famous farmers' markets in DC for the past 10 years helps to improve my diet considerably because the farmers grow organic spinach, kale (5 different varieties), tot soy, mesclun, arugula, eggs, french sorrell, mache, wasabi, yellow, orange & blue cauliflower, purslane, mixed greens stir-fry, swiss chard and white sweet potatoes. Another thing in addition to diet is when you eat...if you stop eating before 7pm each night when your metabolism slows down that positively effects your ability to lose weight and another thing is running early in the morning before 7am which will allow you to burn throughout the day. Another suggestion on running is to only run on dirt, grass & weeds (like in parks, baseball fields, etc) to avoid injury to joints.
