It's usually men of very low self-esteem who end up dating Obeasts anyway. The Obeast is very dominating, true to its selfish nature, and what ends up happening is that the man turns into a husk of his former self. I've seen this happen more than once. The fit, non-overweight man ends up being guilt-tripped into adopting the sedentary lifestyle of the Obeast, and he starts putting on weight as well. He stops running marathons and races, because he feels like he should only do things "together" with the Obeast; obviously, it won't do any running. Sometimes the Obeast even alienates the man from his friends in the process. Meanwhile the Obeast does refuse to eat healthy food and instead takes that over as well, preparing carbohydrate-heavy, salty, processed foods for the both of them. So yes, it does happen, but it is very unfortunate. It's a sad thing to witness a friend's transformation in a relationship with an Obeast. It's very like watching a friend slowly die in front of your eyes.
