Apple cider vinegar seems the “in” thing for weight loss at the moment, sipped in water and sometimes sweetened with honey. As the pandemic loosens it’s hold it seems that more breastfeeding mothers than usual are looking for an answer to weight loss.

There is no research data on whether it is safe in breastfeeding. It certainly isn’t something I would advocate: not least because there is no evidence, that I found, that it’s effective for weight loss although culinary use is unlikely to be an issue. Back to less in, more out – healthy eating and exercise – sigh!

I would NOT advocate this for any breastfeeding mother – or anyone else for that matter

What is the apple cider vinegar diet?

Apple cider vinegar comes from apples that have been crushed, distilled, and then fermented. It can be consumed in small quantities or taken as a supplement. Its high levels of acetic acid, or perhaps other compounds, may be responsible for its supposed health benefits. Although recommendations for “dosing” vary, most are on the order of 1 to 2 teaspoons before or with meals.

What can the apple cider vinegar diet do for you?

For thousands of years, compounds containing vinegar have been used for their  presumed healing properties. It was used to improve strength, for “detoxification,” as an antibiotic, and even as a treatment for scurvy. While no one is using apple cider vinegar as an antibiotic anymore (at least, no one should be), it has been touted more recently for weight loss.  What’s the evidence?

Studies in obese rats and mice suggest that acetic acid can prevent fat deposition and improve their metabolism. The most widely quoted study of humans is a 2009 trial of 175 people who consumed a drink containing 0, 1, or 2 tablespoons of vinegar each day. After three months, those who consumed vinegar had modest weight loss (2 to 4 pounds) and lower triglyceride levels than those who drank no vinegar. Another small study found that vinegar consumption promoted feeling fuller after eating, but that it did so by causing nausea. Neither of these studies (and none I could find in a medical literature search) specifically studied apple cider vinegar.  A more recent study  randomly assigned 39 study subjects to follow a restricted calorie diet with apple cider vinegar or a restricted calorie diet without apple cider vinegar for 12 weeks.  While both groups lost weight, the apple cider vinegar group lost more.  As with many prior studies, this one was quite small and short-term.

In all, the scientific evidence that vinegar consumption (whether of the apple cider variety or not) is a reliable, long-term means of losing excess weight is not compelling. (On the other hand, a number of studies suggest that vinegar might prevent spikes in blood sugar in people with prediabetes and type 2 diabetes by blocking starch absorption — perhaps that’s a topic for another day.)

Is there a downside to the apple cider vinegar diet?

For many natural remedies, there seems to be little risk, so a common approach is “why not try it?” However, for diets with high vinegar content, a few warnings are in order:

• Vinegar should be diluted. Its high acidity can damage tooth enamel when sipped “straight” — consuming it as a component of vinaigrette salad dressing is a better way.
• It has been reported to cause or worsen low potassium levels. That’s particularly important for people taking medications that can lower potassium (such as common diuretics taken to treat high blood pressure).
• Vinegar can alter insulin levels. People with diabetes should be particularly cautious about a high vinegar diet.

So what?

If you are trying to lose weight, adding apple cider vinegar to your diet probably won’t do the trick. Of course, you’d never suspect that was the case by the way it’s been trending on Google health searches. But the popularity of diets frequently has little to do with actual evidence. If you read about a new diet (or other remedy) that sounds too good to be true, a healthy dose of skepticism is usually in order.“
