Bro 8% bodyfat is not sustainable for a long time without feeling like absolute shit and you're not going to be able to afford cheat meals if that is your goal( it's also going to be paired with extreme fatigue. You shouldn't really have a bodyfat percentage goal in mind that you want to achieve because BF% is really hard to determine so posts like that picture just give you false expectations. If abs is what you want, train them 2 - 3 times a week like you would any other muscle. Eat in a calorie deficit, avoid processed and high sugar foods and most imporantantly avoid alcohol.
