I have never seen any research that has discussed weight loss, fatty deposits and excess water. I would demand some proof for these statements. Meanwhile, you can consider these claims to be speculative and unproven. As for the 450-milligram dose, we don't know what an effective dose is. We also don't know what the effects are of taking resveratrol by itself.
Wine contains more phenolic compounds than just resveratrol.
It includes quercitin and catechin, each of which is currently being investigated for its health-promoting properties. At present, the total phenolic content of wine, including resveratrol, quercitin and catechin, is estimated to be 2,500 milligrams per liter. That would translate to just under 300 milligrams to a 4-ounce glass of red wine. My granddaughter is very susceptible to mosquito bites. No one else will be bitten, and she will be covered with bites.
