How do you follow the apple cider vinegar diet?
Most followers of the ACV diet advocate taking 1-2 tbsp (15-30ml) of ACV per day mixed with water. The dose should be spread out over a 24 hour period, potentially consuming the diluted dose directly before meals.
When you first introduce ACV, many suggest starting with a lower amount, say 1 tsp (5ml), diluted in water, to assess your tolerance to it.
The diet involves the inclusion of ACV as a supplement to meals, there is no restriction on what you eat while following the diet.

What is the evidence for the apple cider vinegar diet?
There is currently no specific evidence to support the efficacy of the ACV diet, however, there are some interesting studies which assess the potential dietary effects of vinegar. For example, animal studies have suggested acetic acid in vinegar may help to promote fat loss and burning, reduce fat storage, manage appetite and improve blood sugar and insulin response. Some human studies appear to replicate this, with a 2009 study showing a modest weight loss combined with lower blood fat (triglyceride) levels for those who included vinegar compared with those who didn’t.
This evidence suggests that it may not just be ACV, but potentially other vinegars with a high acetic acid content, that may provide these benefits.
Will I lose weight following the apple cider vinegar diet?
To date there is inadequate quality research to support ACV as a weight-loss aid. More large scale, long-term clinical studies with minimal bias are needed before conclusions may be made.
Is the apple cider vinegar diet healthy? A nutritionist’s view…
When included as an addition to a varied diet apple cider vinegar may offer potential health benefits such as helping manage blood sugar and insulin levels, especially after a carbohydrate-based meal. However, don’t expect it to be the answer to your weight loss issues – a healthy, balanced diet combined with physical activity remains the answer to sustained weight loss.
Less is more when it comes to apple cider vinegar. Taking more than the recommended 1-2 tbsp may be harmful, it may interact with prescribed medication or lead to dental damage by causing erosion of the tooth enamel. Taken undiluted and as a single dose, ACV may cause nausea and a burning sensation to your mouth or gullet.

Who shouldn’t do the apple cider vinegar diet?
Although occasional use is safe for most of us there are a number of people who should not attempt the ACV diet. These include those with the chronic condition known as gastroparesis, where the movement of food from the stomach to the small intestine is delayed. For these people, ACV is likely to make their symptoms worse.
It is also worth remembering that ACV is highly acidic so it may irritate the throat if you drink it often and in large amounts. For those with histamine intolerance, fermented foods, including vinegar, may aggravate their symptoms. ACV may also interact with certain supplements and drugs, including diuretics and insulin.
Talk to your GP or healthcare professional before starting any new diet, especially if you are under 18 years old, elderly, have a pre-existing medical condition or are on medication including diuretics, insulin or blood sugar balancing drugs.
