Many psychiatric drugs have a side-effect of increased appetite.
As soon as I agreed to take Olanzapine I found I was getting hungry far more frequently while having less and less interest in exercising. On a combination of lithium and Olanzapine I steadied out at around 45 pounds heavier than my usual weight. I am sure I got off lightly as I know many people who about doubled their weight while taking Olanzapine.
I have said/blogged about how my weight came down as I reduced my lithium intake. Now, I believe the bigger factor was my being able to gradually reduce my intake of Olanzapine and eventually coming off all psychiatric drugs. My weight is now about what it was before starting on these drugs.
What has been bothering me for a while is that bad eating habits that set in while I was on Olanzapine keep coming back. Perhaps those habits have never left me.
I have read and watched lots and lots about the importance of fasting, or at least having several hours between meals and not eating when we should be sleeping. My scientific background allows me to feel I understand why eating less often is so beneficial, yet knowing stuff does not necessary make changing habits any easier.
After another stressful period I recently realized that I was again eating from early morning until late evening with perhaps a total of 12 meals/snacks! Not on any psychiatric drugs I’ve not been putting on weight but am sure all this eating has been doing me harm.
Since 1st January (yes, sounds like a New Year resolution) I have started to take overnight fasting seriously. A friend has reminded me of an info-graphic from Dr Mercola. See below.
My current plans are nowhere near so ambitious at this time. I am currently seeing getting past 9am without eating and not eating after about 7pm as great achievements and I am just starting to get benefits from this in terms of having more energy through eating less. Yes, sounds a bit bizarre, but by eating less often I mostly have more energy and feel better too.

Intermittent fasting is not a form of starvation but a way for you to time your meals to maximize your body’s ability to burn fat.
