Liquid Diets and Juice Fasting

juice-dietLiquid Diets (or Juice Fasting) are used for a number of reasons – including detox and weight loss. However for weight loss, generally only fluid is lost – not fat.

A liquid diet consists of juices replacing every meal. Nutritionally this will provide virtually no protein or fat, and few calories. However vegetable and fruit juices will be rich in vitamins and minerals and cancer-fighting phytochemicals.

Liquid Diet for Weight Loss?


A Juice Fast should not be used as a weight loss technique. It is better to eat the fruit and vegetables whole – and therefore gain the fiber, and the increased metabolism resulting from digesting the whole food.

There are medically supervised liquid diets (such as Medifast and OPTIFAST) which are used for weight loss. Generally these (expensive) programs will cause quick weight loss – but they are not sustainable as a lifestyle.

Juice Diet Benefits

It may be beneficial to include vegetable and fruit juices in your diet – but not as a complete replacement of solid food. A number of people use a tonic or juice supplement in their diet to provide essential vitamins and minerals. Others claim there are detox benefits to be had from a juice fast. However you should not go beyond a one day juice fast without first consulting your doctor.

Meal Replacement Products

Meal Replacement Products (or MRP’s) are a general term describing products that have a full range of nutrients in them. Most of these are in powder form and when mixed with water or milk provide a liquid-based meal. These are often used by body builders or those looking to gain weight – they help provide macro nutrients in a convenient form, and are sometimes a lot easier than chewing your weight through lots of calories.

    I tried a liquid diet a few years back, the Lemonade Diet, and it was super difficult to stick to it. Needless to say I only did it for 4 days and yeah I lost weight but gained it all back once I started eating solid foods. The diet made me dizzy and weak not to mention the fact that I was starving. Honestly your better off eating healthy and excercising.

    Miranda,

    I am a high school cheerleading coach. Please do not try to lose weight. You sound like you are at a very healthy weight already, especially if you are mainly muscle. The best flyers are not always the ones that weigh the least. It has more to do with technique and proper training than weight. I wish you the best!!

    Miranda,

    It sounds like you are light enough. It also sounds like you could be headed into an unhealthy mindset of always thinking you need to be lighter for some reason or another. If you love cheerleading then let it fit in with who you are and on your terms. Don’t let it conform you into who it wants you to be which is someone of a very unhealthy weight. I wish you all the best.

    Day 3 of a juice only fast. So far I feel great. Day one was hard with lots of growling in the tummy. Now i really am not hungry. I am using organic fruit and veggie juices from Bolthouse and Odwalla these are sold at my grocery store. Most articles I have read on juice fast says to use fresh juices but I KNOW that I wouldn’t be able to afford a $300 juicer so I am trying it this way. I drink a large glass of green goodness in the morning with some liquid vitamins and then throughout the day drink whenever I am hungry. I also have some green or roibos tea and water. The hardest part has been preparing food for my family and then sitting with them at the table with nothing to eat. I may add broth tomorrow and then fresh fruits and veggies. I usually have low blood sugar if I don’t eat so I thought this would not work for me but so far no issues.

    hey laura you can try 2 – 3 ensure plus drinks per day ,, protein ,vitamins ,,but u gotta do a little workin out ,,an if you are a person like me who get headaches when they dont eat ,, then you should try,, im on my 7th day of my liquid fast ,,but if you never went without food for a day ,, an you eat good lol ,, you should start out slow ,, like just eating eggs rice an vegetables for about 2-3 days before trying a liquid fast ,,that way you wont be dying of hunger as to how you will feel if you overly endulge before a liquid fast

    Thanks in advance

    I bought a Jack LaLanne power juicer elite, and I am now on day 20 of my fresh juice and smart water diet I also take a multi vitamin, and have fresh fruit for breakfast. I have lost 13 lbs and I feel great.. I also drink a soy protein drink within one hour of working out, it is EAS Soy Protein 20g per serving. I have one serving of protein per day. But it says you may have up to three depending on your individual needs. It is really working for me. Oh and I also did an acai flush and detox 10 days before starting my program.. let me know what you all think..

I am on day four, I have drank 3 bottles of water and two green teas and two coffee cup sized cups of vegtable broth, I will have chicken broth at dinner time with my smoked oysters if my belly is giving me a super hard time…. weight is still 205, am also exercising as well about 20-30 minutes a day. I began my fiber regim today as well. So is there anybody out there?

  • January 22nd, 2010geri

    I am at day 3 of my Liquid diet, though I did have one meal today of smoked oysters. But that will be it. I am taking vitamins and will begin fiber capsules tomorrow as well. I started at the weight of 210lbs and I am at 205 now. My meals cosist of sugar free finger jello, chicken a vegatble broth (low sodium) and lots of water. I am just doing this for 7 days to jump start my diet as I will slowy introduce a low carb diet. Good luck to everyone and I will try to keep you posted. My energy level seems to be okay though my stomach is growling allot, I drink a glass of water when it growls and then I will drink broth if it does not go away.

  • January 19th, 2010Abby

    Dan, can you tell me exactly what it is that you do? Im really looking to start doing a liquid diet but I have no idea which is best, and all of them sound like ppl are going to die from them lol. But you made it seem like its not as horrible the way youre doing it. Any way you could help me out?

    I’m on Day 4 of a liquid diet and no cramps or extreme hunger. I have no meal times, just liquids whenever I feel like it. Two benefits I think: 1)lower total calorie intake (especially if you use diet drinks and broth which is ridiculously low in calories) and 2)quicker feeling of being full, maybe because the sugar in the liquids gets to the brain faster? Taking vitamins and Omega3 just to be on the safe side. May add some strained meat (baby food) for protein. So far so good….. I’m quite surprised at how easily this is going and my energy level is absolutely normal.
