According to Healthline, an alkaline diet, one that promotes low acidity levels in the body, has long been considered effective in weight loss, but it's really just one of those myths that has been lingering through the years without any real science behind it. Ingesting baking soda, or sodium bicarbonate, is the same as taking an antacid when you have indigestion. It neutralizes any excess acid that gets pushed up into the esophagus from the stomach usually caused by eating a really big meal (via Women's Health).
When you don't have an upset stomach or heartburn, drinking baking soda has no impact on digestive health and fat metabolism, but it will have a chemical reaction in your stomach that causes carbon dioxide gas to be released. That gas will give you a bloated and full feeling which might temporarily curb hunger and cravings, but after a short time will result in a few good burps and that's about it (via Healthline).
Other than easing heartburn and giving you gas, drinking baking soda mixed with water is really just increasing your daily intake of fluids, which one way of promoting weight loss. According to a study published in the journal Frontiers in Nutrition, an increase in daily hydration has been shown to reduce hunger, which means consuming fewer calories and improving your metabolism.
Basically, there are better uses for your baking soda.
