Hi Drumard, it happens! The best time to start is when you are sure you want to pay the price in full! For me I had to have a clear picture in my mind of where I'd be (physically, emotionally, mentally, socially) if I did lose the weight, and where I'd be if I didn't. It helped me to make- before starting- a table of what my weight would be week after week, and what clothes size I'd wear.
It is hard not to feel deprived when on a diet. I got to a point in my mind where I was ready to enjoy the feeling of losing weight more than avioding the feeling of deprivation.
You can't pick at food because your body won't be able to go into ketosis that way. Once you actually start, you'll find within a couple of weeks that you've become detached from food -and that is a great position to be in.
Really, it is do-able and I'm confident that you can and will succeed. Chin-up Drumard!
