One glass a day may help that tummy go away. Well, this is not a proven statement, as your diet, underlying health conditions, hormones, and lifestyle habits all factor into the equation. The best time to drink this juice is 15 minutes before a meal because it works to enhance the digestive process. This juice may also aid in flushing out the colon, which contributes to a flatter stomach. Keep in mind that eating processed foods can tax the digestive tract and colon, so this juice may be less effective if you eat those foods.

This juice only contains two ingredients, both of which have powerful effects on the digestive system. Kiwi is a tart fruit that contains actinidain, an enzyme that aids the digestion of protein in the body. Optimal digestion goes hand in hand with sustainable weight loss because poor digestive function means the body doesn’t break down food particles properly. In fact, eating hard-to-digest foods can slow metabolism and lead to weight gain. Kiwis are also very low in calories but high in fiber, so it may help you feel full without increasing your caloric intake.

Pineapple, the second ingredient in this juice, is another tropical fruit that promotes healthier digestion. It exhibits anti-inflammatory properties and the enzyme bromelain. This enzyme primarily exists in the skin, stem, and core, which are the most fibrous regions of the pineapple. To obtain the most bromelain, dietitians suggest juicing raw pineapples and consuming them that way. Bromelain works as a digestive enzyme that helps the body expend more energy. Because of this action, the body burns more calories, which aids the fat-burning process. One last thing to remember is that pineapples and kiwis alone will not make your fat disappear.
