The 80/20 rule is a marketing line. Try 90/10 instead.

"Why the classic 80/20 rule often degenerates into 60/40, and how 90/10 provides structure while protecting your weekends."
In real life, an '80/20' diet plan frequently degrades into a 60/40 ratio by week three as untracked snacks and social meals creep in.
A 90/10 structure leaves far less room for accidental drift while still granting two fully flexible meals out of twenty across your week.
That is more than enough flexibility to enjoy social occasions without stalling your fat loss or body composition goals.
