The answer to this question is YES! Adding apple cider vinegar to your coffee can help you lose weight, however, you shouldn't drink it on empty stomach. This is because apple cider vinegar contains pectin, which helps to increase the rate of digestion. When the body has more pectin, it can absorb more calories from food without gaining weight.  It also increases the production of enzymes that aid in fat burning. So by adding apple cider vinegar to your coffee, you are getting both benefits at once! You should start by taking one teaspoon per day then gradually increase this amount if needed until you find the right dose for you. If you want to add it into your coffee try adding 1 tablespoon per cup of water before brewing your coffee in order to get the maximum benefits from it without having any negative side effects from taking too much apple cider vinegar.
