I am a 21-year old college student who had been very overweight for most of my life. I am would like to thank you for your informative website. About 1 and a half years ago I began a diet and exercise plan. I had little success, losing maybe 10 of the 91 pounds that is my goal. I found your calculator and used the information on dieting and calorie intake help me design a “lifestyle modification” that has been fantastically successful. I had always dieted but fluctuated between eating too much and starving myself. I wasn’t aware of the metabolism slowing effect of starvation. I would eat so very little, lose no weight and give up over and over. I have lost 73 of the 91 pounds and I’m watching the rest come off. It has changed my life.
