Reduce calorie intake: Lemon water is a good substitute to juices or drinks that may be high in sugar. Especially for those who are diabetic or who intend to lose weight, this is a good drink to rehydrate and energize body without adding dangerous levels of sugar. Drinking plenty of water is advised for quenching thirst and overall good health but people may not drink it because they do not like the taste of plain water. In such cases one may drink lemon water, which is much more flavourful and enjoyable, and get the benefits of both lemons and water.
Healthy liver: Drinking lemon water may also help in activating digestive enzymes present in the liver. It can also help in regulating oxygenation of the blood.
