Would you have an appetite if you were being held hostage in a war zone, had witnessed friends and family be killed and had no idea of the fate of others? It’s not surprising they don’t look healthy and well, they will be deeply traumatised and will have been sick with anxiety every day they were held in Gaza. Plus we know there have been food shortages in Gaza, people have been literally dying of malnutrition. Different areas of Gaza have been affected by the food shortages differently, some areas have had better food supplies than others. The terrorists filmed releasing the hostages were probably not the ones holding them for the last 16 months, if you look on social media you can find plenty of footage of emaciated Palestinians.
I’m not justifying the images of the hostages or saying they haven’t been starved/ tortured, we just don’t know yet and it’s reasonable to think the people who held them captive didn’t treat them well, but equally you can’t compare them with the terrorists hamas chose to be the face of the handover with the hostages and say that because these terrorists look well and the hostages don’t food and morale must be plentiful in Gaza and the only reason the hostages haven’t been laying into feasts every night is because their fat captives have withheld it from them whilst enjoying it themselves.
