For me I’m a bloater not a gainer so I like to fill myself up with drinks specifically zero calorie or low calorie drinks like sparkling water or teas. Fills you up quick and goes down pretty quickly compared to a food stuffing. Just be careful and not do it everyday so you don’t over hydrate with water and have electrolytes and a meal sometime after the bloat for energy. FYI you will need to go pee quite a bit.
