3 Weeks ago I started a diet that my brother is on. I have been counting calories and walking. As of today I have lost 5 lbs. It may not be much but its a start. Here are some web sites that I use.
The Health Calculator
Your Basal Metabolic Rate (BMR) shows the number of calories your body
needs to operate. This doesn't account for any activity, it's simply the energy needed to sustain a heartbeat, breathing and normal body temperature. It measures the body at rest, not sleep, at room temperature.
This BMR calculator was originally developed by Paul Brady at the University of Minnesota Department of Rhetoric and is used with permission. It uses the formula from Harris, James Arthur & Benedict, Francis Gano (1919) "A biometric study of basal metabolism in man," Carnegie Institution of Washington, Washington D.C. pp. 266.
