There are 180 calories in a 1 bottle serving of Ensure Ensure Clear. Calorie breakdown: 0% fat, 80% carbs, 20% protein.
Though it is better to drink Ensure than eat nothing at all, weight will continue to be lost. This is because an 8 oz. bottle of Ensure contains only 250 calories. Therefore, drinking Ensure for breakfast, lunch and dinner will provide you with 750 calories a day. Even if you add another bottle or two a day as snacks, your total caloric intake would be about half of what you should be getting.
