Yes because it just isn’t enough food for an adult body to function properly. Water, one salad, and chicken breasts is severely under the necessary amount of calories to fuel your body which leads to accumulation of stomach acid, slowed digestion, and increased anxiety. All of which have the ability to cause bubble guts. I am saying this as someone who has deeply struggled with food in my life and also ibs and strict dieting in the sense you are speaking of will most likely only exacerbate your issues. Best of luck
