I appreciate the question on how to figure your calorie intake with exercise. I didn't think about the 24 hour and sleep time. I will do that also. I was also confused and could not find an answer anywhere in the website. I didn't understand the -2200 as a total for example. Now I understand moreso. Thank you all. I am also new on here. I am so glad I found this site. I need to lose weight so I can have lower BP and possibly get off the BP medicine. Thanks again.
