Can one lose weight by drinking only liquids?

Question

Hello doctor,

I have been trying to lose some weight, and a friend told me about this liquid diet thing. You just drink your meals instead of eating solid food. Sounds extreme, but I am curious. Can you lose weight by only drinking liquids? More importantly, is it healthy? What kind of drinks are we talking about here - just water or stuff like smoothies and protein shakes too? How long can someone safely do this? Are there any risks I should know about? And what happens when you go back to regular food? Just wondering if this is worth trying or if I should stick to more traditional diets.

Kindly help.

Hello,

Welcome to icliniq.com.

Thank you for posting your query.

These drinks may replace all of your meals or just one or two meals (usually breakfast and lunch). You also get snacks on some of these plans. These diets can cut the calories you take in and can help you lose weight, but you shouldn't stay on them for very long. Talk to your doctor before you go on a liquid diet. You will need to make sure you get enough important nutrients, like fiber and protein. Liquid diets can be difficult enough, but certain people should never consider a liquid diet. Liquid diets could be dangerous if you are pregnant, breastfeeding, on certain medications, have had a recent procedure, or have intestinal or digestive issues. The 7-day liquid diet is a short-term weight loss plan that involves consuming only liquids for seven days straight. This can include juices, smoothies, soups, and broths. It is important to note that liquid-only fasting should be undertaken for a brief duration and under medical supervision. This is because a solely liquid diet lacks sufficient calories, vitamins, minerals, and other essential nutrients to sustain the body over an extended period. On average, people can lose anywhere from 3 to 10 pounds on a three to seven-day juice cleanse. However, some people have reported losing up to 20 pounds on a longer cleanse. It is normal to feel nauseous, have a headache, or become irritable during the first 48 to 72 hours of your liquid diet. These bad feelings will pass as your body gets used to the diet. It is also normal to have loose stools and need to use the restroom frequently during the liquid diet.

Here are some health risks of a liquid diet:

Low blood sugar.
Hormonal imbalance - Diet plays a vital role in the management of hormones.
Gastrointestinal problems.
Stress.
Low blood pressure.
Muscle loss and low energy.
Feeling light-headed or dizzy.
Too few calories.
Lack of important nutrients.
Not sustainable long-term.
Lack of satiety.
Expensive.
Suggest going with a balanced diet as once starting with meals you may gain weight.

I hope this helps.

Thank you.
