Apple cider vinegar for weight loss: Effective?
Drinking apple cider vinegar for weight loss seems far-fetched. Does it work?
from Katherine Zeratsky, R.D., L.D.
Drinking apple cider vinegar for weight loss isn't likely to be effective.
Proponents of the apple cider vinegar diet claim that drinking a small amount of apple cider vinegar before meals or taking an apple cider vinegar supplement helps curb appetite and burn fat. However, there's little scientific support for these claims.
Although occasional use of apple cider vinegar is safe for most people, it won't likely lead to weight loss — and it may pose problems of its own. For example:
- Apple cider vinegar is highly acidic. It may irritate your throat if you drink it often or in large amounts.
- Apple cider vinegar may interact with certain supplements or drugs, including diuretics and insulin. This may contribute to low potassium levels.
Remember, there's no magic bullet for weight loss. The key to losing weight is burning more calories than you consume. Choose healthy foods — such as fruits, vegetables, whole grains and lean sources of protein — and include physical activity in your daily routine.Next question
