Q: I'm dieting and trying to enter into a ketosis state. Will drinking two glasses of wine per day hamper my efforts? —Bill U., Terre Haute, Ind.
A: Ketosis is a metabolic state that occurs when there isn't sufficient glucose to burn for fuel. The body then turns to other available fuels to use, like reserved fats and ketones. Dieters may try to achieve this state in order to facilitate weight loss and burn fat. The most common way of achieving this is through a very low-carbohydrate diet. Other factors such as strenuous exercise, fasting and diabetes can also trigger ketosis.
When it comes to alcohol, exercise and your diet, there are certain parameters to take into account. According to Lisa M. Moskovitz, RD (registered dietician), CDN (Certified Dietitian/Nutritionist) and CEO of the NY Nutrition Group, "Alcohol can slightly stall fat burning during ketosis as, after it is consumed, it will be burned for fuel first over fat. The amount it delays or prevents fat-burning will vary from person to person. Some people do not notice major differences while consuming alcohol in moderation, or 5 ounces of wine for women and 10 ounces of wine per day for men, while others do notice that it competes with ketosis state. You will have to experiment on your own and keep in mind that if your goal is to be healthy and manage weight, ketosis is not something that's necessary or even recommended from a clinical standpoint."
