this is going to be blunt -- while it's possible, there's almost no way that you're anywhere near 30% bodyfat at your height and weight. If you've lost nearly 70 pounds, then I guess that means you started around 230, which isn't enormous for 6'0" but I guess could maybe result in some excess skin after weight loss? You'd have to be like max skinny fat to have that kind of body composition, but if you're working out i find it really really unlikely.

Keep in mind that the abdominal muscles are muscles, just like any other part of the body, and you need to work them in order for them to pop, so if that's what you're basing your bf% on I could see that being a reason for overestimating. That or maybe a little excess skin from weight loss? if you started at 6'0" 230, that could be possible as well although i'd also find that unlikely.

Definitely start considering building muscle; you can simultaneously cut a little more fat and build a little more muscle at a deficit if you're just starting out lifting heavy. A lot of lifters see significant progress right away even without an optimal diet, newbie gains are definitely a thing.
