Is there any scientific evidence supporting the use of baking soda for weight loss?

Reviewed by Yoshinori Abe, MD

Baking soda is not a proven weight loss aid. No scientific evidence supports the claim that consuming baking soda helps you lose weight, and doing so can be dangerous. Risks include electrolyte imbalances, metabolic alkalosis, high blood pressure, and, in severe cases, stomach rupture from gas buildup.

If you're struggling with weight or noticing symptoms like bloating, fatigue, or unexplained weight changes, guessing at solutions—or trying unproven remedies like baking soda—can waste time and put your health at risk. A better first step is to understand what your body is actually telling you. Take a free, instant, online symptom check to identify possible causes and get guidance on smart next steps, backed by medical research and trusted by millions.

Explanation

Baking soda, also known as sodium bicarbonate, is not proven to help with weight loss. The references provided do not discuss weight loss benefits from baking soda. Instead, they focus on its use in sports nutrition and potential toxicity.

Sports Nutrition: One reference investigates sodium bicarbide in sports, but it does not mention weight loss. Sodium bicarbonate is sometimes used by athletes for performance enhancement, not for losing weight.
Toxicity Concerns: Another study highlights the risks of sodium bicarbonate toxicity. Using it improperly can lead to health problems, making it unsafe for weight loss attempts.

In summary, there is no evidence from the provided references that supports using baking soda for weight loss. If you're experiencing unexplained weight changes or other health concerns, take our free AI-powered symptom checker to better understand what might be happening with your body. It is important to be cautious and avoid using baking soda for weight loss purposes to prevent health risks.
