Ah, well beefy, to me is someone kind of.....well....beefy, but not fat, they're like built or more or less muscular.
There there's just fat. I've been kind of pudgy the last couple years, but as of 2 weeks ago yesterday, I am working on changing that.
It's not easy, but it sure is rewarding. I'm shooting for a BMI of 20. Although the BMI itself isn't as important as just getting my weight itself down.
