I did that in 2020. May through November. 40 pounds off. Then I sprained my ankle. I apologize for being negative, but come back in a year and let us know how it's going. Many, many people can lose 10%, 20%, even 30% of their body weight with concerted effort. Works for a year or maybe two. It's actually pretty easy, to be honest, most people who've done it will agree with me.
