While many of us pay attention to what we eat, we often ignore those calories consumed in liquid form. However, these could add up to a significant amount of your daily total. While alcohol is the main liquid calorie culprit, soft drinks, fruit juice, smoothies and many hot drinks can also contain a vast amount of calories, and often next to no nutritional value. To reduce your calorie intake without changing what you eat, try swapping calorie-rich drinks for herbal tea or water. Alternatively, replace milky lattes for skinny versions and fizzy drinks for fruit juice diluted with sparkling water.
