Apple Cider Vinegar for Weight Loss: Does It Work?

If you want the short answer: apple cider vinegar is not a weight-loss product on its own, but the research suggests it may have a modest effect on some markers of body composition when it is consumed daily for several weeks alongside a balanced diet. In a meta-analysis of 10 randomised controlled trials, with 789 adults and interventions of at least 4 weeks, daily apple cider vinegar consumption significantly reduced body weight, BMI and waist circumference, although the effects were modest and heterogeneity between studies was high ¹.

So the honest answer is: there is a signal, but it is small, and it does not replace the essentials — diet, physical activity and sleep. This article explains what the studies measured, what they did not measure, the doses used (which are not dosing instructions) and how to fit apple cider vinegar into your routine, including the gummy option.

What do studies say about apple cider vinegar and weight loss?

The most direct evidence comes from meta-analyses of randomised controlled trials. The 2025 meta-analysis, which pooled 10 trials and 789 adults with excess weight and/or type 2 diabetes, found statistically significant reductions in body weight, BMI and waist circumference with daily apple cider vinegar consumption for at least 4 weeks ¹. The same work found no significant effects on the other body composition parameters assessed ¹.

It is important to read these results with caution: they are mean differences between groups, measured with standardised scales, and heterogeneity between studies was high (I² above 60% in several outcomes) ¹. This means the studies did not all measure the same thing in the same way, and that individual response can vary considerably.

How much weight can you realistically expect to lose?

Meta-analyses do not allow the results to be translated directly into kilograms for each person, because they combine studies with different populations, doses and durations. What can be said with confidence is that the effects observed were modest and that clinically relevant weight loss rarely results from a single ingredient ¹.

In addition, most of the trials included assessed adults with excess weight and/or type 2 diabetes, so the results do not automatically generalise to everyone ¹. If your goal is sustainable weight loss, apple cider vinegar should be seen as a possible add-on, not as the main strategy.

How might apple cider vinegar influence weight?

The proposed mechanisms include effects on glucose and lipid metabolism, but the evidence in humans is indirect. A meta-analysis of 9 studies (10 arms) found significant reductions in total cholesterol, fasting plasma glucose and HbA1c with apple cider vinegar consumption ². A more recent meta-analysis, with 25 clinical trials (33 arms) and 1,320 adults, found significant improvements in fasting glucose, HbA1c and total cholesterol, but not in BMI, HOMA-IR, fasting insulin, triglycerides, LDL-C or HDL-C ³.

These results suggest a possible effect on glycaemic control, which is relevant to metabolism, but they do not amount to a direct effect on fat loss. A network meta-analysis comparing several herbs in people with type 2 diabetes placed apple cider vinegar among the options with a significant effect on fasting glucose and HbA1c ⁴ — but note that this population is specific and the results should not be extrapolated to healthy people who want to lose weight.

Doses used in studies vs. what is on the label

In the trials, doses vary considerably. In the body composition meta-analysis, the studies included used daily amounts of apple cider vinegar over at least 4 weeks, but the doses are not uniform across trials ¹. In a randomised trial in women with polycystic ovary syndrome taking metformin (1,500 mg/day), a dose of 1,500 mg per day of apple cider vinegar in capsules was used for 12 weeks ⁵ — but this is a specific population and the context is a clinical trial with concomitant medication, so it is not a model for general use.

If you use liquid vinegar, the most cited practical reference is 1 to 2 tablespoons per day, always diluted in a glass of water — never neat. To go deeper into amounts and ways of diluting, see the article on how much apple cider vinegar you should take per day.

TuttiBear Appetite Control Gummies provide 1,000 mg of apple cider vinegar per serving of 2 gummies, plus vitamin B6 (1 mg; 71% NRV), folic acid (400 µg; 200% NRV), vitamin B12 (2.4 µg; 96% NRV), iodine (100 µg; 67% NRV), pomegranate juice powder (80 mg) and beetroot juice powder (80 mg). The directions for use state to chew 2 gummies per day, preferably after a meal, without exceeding the recommended daily dose. Remember: doses used in studies are not dosing instructions; always follow the product label.

Does apple cider vinegar help control appetite?

This is one of the most popular claims, but the evidence available in the abstracts reviewed does not allow us to state that apple cider vinegar reduces appetite consistently. The meta-analyses available focus on anthropometric and metabolic parameters, not on subjective measures of hunger or satiety ¹².

What is known is that appetite control is influenced by many factors — meal composition, fibre, protein, hydration, sleep and stress — and that no single ingredient replaces those pillars. If your goal is to manage your food intake better, it is worth starting there.

Effects on metabolism and glycaemic control: what is relevant to weight?

Glycaemic control is relevant to weight because frequent glucose spikes may be associated with more hunger and higher calorie intake. The meta-analyses show that apple cider vinegar may reduce fasting glucose and HbA1c in adults, including people with type 2 diabetes ²³. However, these studies did not directly measure weight loss as the primary outcome, so it cannot be concluded that improved glycaemia automatically translates into weight loss.

In addition, a significant part of the data comes from populations with specific metabolic conditions, and the results should not be generalised without that caveat ³⁴.

How to include apple cider vinegar in your routine

If you decide to try it, the simplest approach is to choose a format you can keep up consistently. The options include:

• Diluted liquid vinegar: never neat, to reduce the risk of irritation of the oesophagus and tooth enamel; use a straw and rinse your mouth with water afterwards.
• Capsules or tablets: convenient, but with less flexibility in taste and texture.
• Gummies: a convenient and pleasant format, without the sour taste of liquid vinegar. Appetite Control Gummies provide 1,000 mg of apple cider vinegar per 2 gummies, with the directions for use on the label.

Whatever the format, the time of day matters less than consistency. If you want to go deeper into this point, see the article on the best time to take apple cider vinegar.

Safety and side effects: what you should know

Apple cider vinegar is acidic and, on repeated contact with the teeth and oesophagus, it can cause tooth enamel erosion and irritation. Always diluting it and not drinking it on an empty stomach without water is a basic precaution. People with gastro-oesophageal reflux, gastritis or ulcers should be especially cautious.

High doses of liquid vinegar may cause nausea or indigestion, so it is worth staying within the recommended amounts and not concentrating the intake. If you have a sensitive digestion, start with small amounts and monitor your tolerance.

In addition, apple cider vinegar may interact with medicines, including diuretics and insulin, so anyone taking medication should speak to a healthcare professional before using it. If you are pregnant, breastfeeding, have a medical condition or are taking medication, always consult a healthcare professional before consuming any supplement. For a more detailed analysis, see the article on whether apple cider vinegar is safe for daily use.

The gummies contain polyols (maltitol), the excessive consumption of which may have laxative effects; do not exceed the daily dose stated on the label. Keep supplements out of the reach of young children.

Limitations of the evidence: what we still do not know

Despite the growing number of trials, there are important limitations. Heterogeneity between studies is high, doses and durations vary, and many samples are small ¹. In addition, most studies do not directly compare apple cider vinegar with a placebo under perfectly controlled diet and physical activity conditions, which makes it difficult to isolate the effect of the vinegar.

There is also no evidence that allows us to state that gummies are equivalent or superior to liquid vinegar in terms of effect on weight loss — there are simply no studies comparing formats. What is known is that gummies provide a defined dose of apple cider vinegar per serving and are a practical way to include it in your routine.

Conclusion: is it worth trying?

Apple cider vinegar may have a modest effect on some markers of body composition and on glycaemic control, but it is not a standalone solution for weight loss. If you decide to include it, choose a format you can keep up, respect the label and do not exceed the recommended dose. And remember: sustainable results come from a balanced lifestyle, not from a single ingredient.

Frequently asked questions

Does apple cider vinegar really help with weight loss?

The research suggests a modest effect. In a meta-analysis of 10 randomised trials with 789 adults, daily consumption for at least 4 weeks slightly reduced weight, BMI and waist circumference. It is not a standalone solution and results vary between people.

How much apple cider vinegar should I take per day?

The doses used in studies vary and are not dosing instructions. If you choose a supplement, always follow the directions for use on the label. Appetite Control Gummies provide 1,000 mg of apple cider vinegar per serving of 2 gummies, with the instruction to chew 2 gummies per day, preferably after a meal.

Are apple cider vinegar gummies as effective as the liquid?

There are no studies directly comparing gummies with liquid vinegar in terms of weight loss, so equivalence or superiority cannot be claimed. Gummies have the advantage of being practical and of not exposing the teeth to the acid, but the effect depends on the total dose consumed and the dietary context.

How long does it take to notice results?

The trials included in the meta-analyses had minimum durations of 4 weeks, and most assessed longer periods. There is no guaranteed timeframe: results depend on many factors, including diet, physical activity and adherence to the plan.

Does apple cider vinegar have side effects?

Vinegar is acidic and can irritate the oesophagus and tooth enamel if consumed neat or in excess. People with reflux, gastritis or ulcers should be cautious. It may also interact with medicines such as diuretics and insulin; speak to a healthcare professional before using it.

Can I take apple cider vinegar on an empty stomach?

Consuming neat liquid vinegar on an empty stomach is not recommended, due to the risk of irritation. If you use liquid vinegar, always dilute it in water and prefer taking it with a meal. Gummies, being a solid format, are generally better tolerated, but always follow the directions for use on the label.
