Weight loss is fine but don't get extreme about it. I went from 202 to 170 for training purposes (Brazilian Jiu Jitsu) but the benefits simply weren't worth it for me. Yes I had abbs and yes my cardio was slightly better, but I lost a noticeable amount of strength and overall just didn't feel as durable. Bulked back up to 190ish which seems to be the sweet spot for me. I feel 100% better overall even without abbs.
