I would argue yes- but based on what water does to hydrate the body in order to work out more.
If someone is drinking a lot of fluids that are not good for the body when you workout, their workout will not be 100%. Drinking water allows them to put a maximum amount of effort in as well as aid the body in recovery.
It is especially important for athletes, both endurance and strength.
Conventional wisdom says ‘maybe.’ Since drinking during a meal can help fill the belly, that alone may make overeating a little less apt to happen.
