When I started at Sparkpeople I weighed 166. I'm a male, 6' tall. I didn't want to lose any weight. I had a kidney transplant 9 years ago. I wanted to make sure I was eating enough and the right kind of food. Sparkpeople recommends eating around 1800 calories for my BMR. I do that but I consistently burn 400, sometimes much more, calories than that. Today I weigh 157.5. I feel good and my blood tests are fine. But should I alter my calories for how much I burn every day or stay at the 1800?
