UNDATED (CNN) -- If you've eaten too much over the holidays, it may be time for an all juice detoxification cleanse. Doctors recognize the nutritional benefits of a well-planned juice fast or cleanse. They say a liquid-only diet can give the digestive system a much needed rest and restore energy.
But doctors warn this growing trend, can be dangerous if you overdo it. You can use fruits and vegetables like cucumber, kale and pear. At first you may feel groggy, but after a couple of days, those who've tried it felt energized later on.
Doctors say just consuming juice isn't enough, because our bodies need to break down solid foods. Juicing can throw off our digestion, in how we get nutrients, electrolytes and sugar.
Experts say you should speak to your doctor before starting any juice fast or cleanse.
