Liquid diets are often used for weight loss or medical reasons and involve consuming foods and beverages in their liquid form rather than solid foods. Some examples of liquid diet recipes include smoothies made from fruits, vegetables, nut butters or protein powder blended with milk or yogurt, vegetable or bone broths, protein shakes, and fresh fruit or vegetable juices. Sticking to a liquid-only diet should be done under a doctor's supervision and is generally not intended for long-term use.
