I recently joined Weight Watchers to lose 15 unexplained pounds that I've gained. I'm 48 years old and weighed 150 when I joined two weeks ago. I have lost 4.4 lbs. in two weeks. I'm also walking on my treadmill every night for 25 minutes and doing light exercise.
They say it is important to use ALL the points allowed in a day or I could gain weight. Is this true? Can you gain weight from not eating enough??
Yes and no. If you restrict your intake to a level which is too low (below 1200 kcal), your body will go into starvation mode and will decrease it's basal metabolic rate (BMR) which may in turn cause you to maintain or gain weight. Our bodies are designed to maintain weight. We have not evolved from our ancestors who required this mechanism in times of drought and hunger.
