you can look online but it mainly comes down to reading packaging.. they word stuff in ways that can trick you into eating carbs.. when you read people talk about it, they make it sound complicated but it's crazy easy.. just no carbs/sugar.. after a few days your body stops running on sugar and runs on protein and burns all your fat away. PLUS... crazy energy all day and you can eat like a pig non stop and still melt off weight..
I felt like i was 18 again honestly... even started getting random erections which hasn't happened in 35 years... I really need to go back on keto.. sugar addiction is a ****** though.
