How can my bf (28 M) achieve a natural but also an aesthetically good physique?

I’m a gym rat myself. I lost 25 pounds and I’ve gotten a lot leaner learning from Greg and this community. However, I’m a girl. My training and aesthetic is completely different compared to guys.

Basically, I’ve been trying to push my bf to get himself in shape. He’s done work and I’m proud. But I don’t think it’s working.

He’s 28 Male, 5’8 and around 160- 165 pounds. I taught him about protein, macros, tracking, and progressive overload. But after a while, I don’t see much progress. Yes he’s gained something, but comparing him to others 1 year transformations here is absolutely insane! I see men achieve such an impressive physique, yet my bf is still skinny fat, has a huge gut, and very skinny arms, chest, and legs. Especially after 1 year of trying.

As a girlfriend, I’m doing the best I can to motivate him, push him, and even train together. But I honestly don’t know what else to do to help him. He doesn’t have great genetics, family is severely obese and has loads of problems with diabetes, cholesterol and high blood pressure.

He’s currently trying to track protein and he’s also on creatine. But i don’t think he’s tracking or training right….

I’m just curious if anyone here had an amazing transformation starting as a skinny fat person with a big gut? If you have any advice, what should my bf do to improve his goals? He wants the typical bigger arms, bigger chest and a leaner belly. Id appreciate the male advice!

Thanks!
