Each one of us has to do this individually. Whatever works best for you is up for you to decide. If you are having problems going cold turkey, then don't. Try one meal per day and see how that works. Dinner would be best for a few reasons - which we can get into, but you are new so it might be too much info too soon. Breakfast is always a good choice as well, but again it would depend. Do you have a significant amount of fat to lose? Are you doing this to help with a problem/disease or you just don't want a problem/disease?
People too weak to follow their own dreams will always try to discourage others.
