Hello,

I am a psychologist not a physician, but I would say people should anticipate some hunger on a weight loss plan, but they should not be feeling shaky, jittery or weak. If you feel this way you may have a medical problem that is not being addressed. And, how can one continue on a weight loss program if I they are not feeling well? Too often people get too restrictive or over-exercise because weight loss is so important to them. I would recommend you review your program with your physician and then meet with a dietitian to create a personalized weight loss program. The key is building a program that you can follow over time, one that is healthy and maintainable for you.
