Five years ago I was obese, and have always been heavier than I look. Then I started running/ working out consistently and depending on what I do , I can look more or less chunky. I do prefer my runner's body, but unfortunately for medical reasons I can't run just yet. I'm still heavy though! And I don't lift enough to think that it's the "muscle is denser than fat" theory. Size wise I'm happy-ish but maybe I would be less flabby. Anywho, who would be the best to advise a PT? A nutritionist? A GP? Photos for reference
