Hi Wayne. Apologies for this approach straight off the bat, but a few personal questions may help us provide advice. If you don't want to answer, not a problem.
Do you know what your basal metabolic rate (BMR) is? This can vary from calculator to calculator, depending on how you've calculated it (if you have).
How often do you weigh yourself? Do you always do it at the same time on weigh in days?
You say you're not losing any weight. Are you maintaining the same weight, or does it just fluctuate around a similar level?
How much weight do you want to lose? What is your expectation/desired weight loss per week?
