Lemon water is low in calories and promotes satiety in the same way that ordinary water does, so it can be an efficient strategy to help reduce calorie consumption. Regular water and lemon water can help enhance satiety and fullness, which can contribute to calorie reduction and weight loss. However, there isn't any evidence that drinking lemon water before a meal will increase your appetite or block fat absorption. Lemons contain acid that helps dissolve other foods such as proteins and fats. When you drink lemon water, all of these dissolved nutrients are available for digestion and use by your body. Some studies have shown that acid reflux patients experience less heartburn after drinking lemon water. This may be because lemons reduce the amount of acid in the stomach, allowing food to pass through more easily. Lemon juice has been used for centuries as a natural remedy for a variety of health issues. It can also help reduce the risk of cardiovascular disease and certain types of cancer, make teeth brighter, and aid in digestion. However, too much acid in the body can cause problems such as osteoporosis, kidney stones, and arthritis. Also, avoid eating fresh lemon with fatty foods as this can lead to heartburn. Instead, eat fatty foods like fish and chicken with vegetables to get the most benefit without causing harm.
