I do like an occasional chocolate treat and the ale as I said aside, always eat healthily and home made anyway so you definitely need to consider this too for the results - but being one main meal a day anyway I really do like to focus on it being a good one and something to look forward to.
Fasting beforehand clearly accentuates this but logically makes it easier to be more mindful on what you are throwing down your neck
Protein as well is the one coming off a fast, but I love chicken so piss easy
