If you're constantly eating bread or bread-like products and start to swap them with non-starchy veggies or protein sources, there's no denying that you'll see a significant difference in your weight (hence why diets such as keto have become so popular). Not only will your diet become healthier, but you'll also see a difference thanks to the decreased water weight in your body due to the carbohydrates. According to Medical News Today, every gram of carbs you consume comes with 3 grams of water attached to it, hence the term "water weight."

This will depend on the type of bread you consume. If you're giving up regular ol' white bread, this may not be much of a problem for you. But if you plan on giving up whole-grain bread or sprouted bread that's still full of the original fiber from the wheat, going to the bathroom may be an issue for you.

Fiber is helpful for your digestive system and keeping you regular in the bathroom, and fiber-rich bread products can be an easy way to increase your fiber intake to the recommended 25 to 30 grams a day, according to the AHA. One slice of whole-grain bread could have anywhere from 2 to 4 grams of fiber per slice (sometimes more), so a sandwich can give you almost 8 grams of fiber before you even fill it.

If you still plan on giving up bread, be sure to replace that fiber source with something else. Here's a list of 43 Best High-Fiber Foods For a Healthy Diet that will also help in the bathroom.

Weight loss is likely a significant reason people decide to give up bread, but the risk of disease is also another significant reason to cut down on your bread intake. One study published by PLOS One showed how refined carbohydrates (white bread products that have been stripped of their natural nutrients, including fiber) can drive up the fatty acid levels in a person's body, which raises the risk of heart disease and type 2 diabetes. So giving up processed, refined white bread may be wise.
