“In general, men should limit alcohol intake to two drinks [a day] and women to one,” advises Susan Weiner, MS, RDN, CDE, CDN. “Drink” means a 5-ounce glass of wine, one 12-ounce beer, or a single shot (1.5 ounces) of distilled spirits. “Avoid anything with an umbrella. Sugary cocktails can have a huge impact on your blood sugar,” notes Weiner. Choose seltzer or diet soda as mixers instead. Also keep in mind that alcoholic beverages can lead to low blood sugar (hypoglycemia) both right after you drink and up to a day after. Make sure to check your blood glucose level before bed to ensure that it's within a safe range.
