Juice Fast Weight Loss Total

Juice Fast Weight LossIt’s the end of the month, end of my juice fast and I haven’t posted an update since the 10-day mark.

I’ve had a lot of questions about my juice fast weight loss. When we left off, I’d lost 8 lbs in 10 days. I’d made it through the tough transition phase, learned it’s not easy to keep up a juice fast while traveling and realized that intense exercise and juice fasting didn’t mix well.

I’ll post a final juice fast weight loss total (with a graph) at the end of this post.

Incorporating Some Solid Food

These monthly experiments are done in the name of fun. I’m a big fan of pushing my own limits, of personal development and doing hard things for the sake of doing hard things. Every so often, I have to draw a line.

I hit a wall with the juice fast around the 2-week mark. Despite increasing my juice intake, I started to feel pretty weak. I’d feel fine while just sitting around the house, felt great while at work, but running just wasn’t possible. Even walking for 4-5 miles made me feel lousy. I lead an active lifestyle and being light-headed and weak just doesn’t work for me. So, I had to modify the rules a bit.

One of the rules I had for this experiment was: If I drop below a healthy weight, I will start eating nuts and legumes. My weight was already dropping faster than I could sustain, and I figure that if I can’t walk my dog in the afternoon, it’s not healthy. So I started adding some protein into my diet in the form of nuts and beans.

I always feel bad when I don’t meet a goal I set for myself, but in this case I realized that my goal was unhealthy and modifying it was smart.

After incorporating some more protein, I started to feel better very quickly. I’d still have the same amount of juice each day, just supplemented with some simple solids. Not only did my dizziness go away, I was able to start walking and running again.

If you’re an athlete and considering a juice fast, I suggest keeping it short, or not being too strict. I’ve talked to other people who have done a juice fast and felt great the whole time. None of them run 5 miles a day, so, that’s probably where my problem was. Just as I learned during my workaholic experiment, sometimes I try to do too much. 🙂

Another Road Trip

Santa Monica Mountains HikeSomething you’ll learn about me as you read this blog is that I go on a lot of road trips. Pretty much any weekend that my wife and I don’t have an obligation (or weather) keeping us home, we tend to hit the road and try to have an adventure.

We took a 3-day weekend from the 18th to the 20th and headed down to Los Angeles. When I weighed in on the morning of the 18th, I was down 8lbs from my start weight. I knew I wasn’t going to try to keep up a juice diet, but planned to have juice for at least one meal a day. If you’ve read this blog for long, you know I’m basically addicted to Mexican food. 🙂 LA has so much amazing Mexican food, resistance would have been futile.

I was interested to see how the return to a solid food diet would go.Would I get full quickly or feel sluggish? Not really. I had Mexican food for breakfast, lunch and dinner. It was surprisingly uneventful. I also got to have a ton of fun on the trip, spending some quality time with friends and family, hiking through the Santa Monica mountains and enjoying the change of pace.

I didn’t really think much about the juice fast until I got home. That’s when things got interesting. When I weighed in the day I got home, I expected to have put on 3 or 4 pounds. I was shocked to see I was the exact same weight as before my trip. That was weird.

If you look at the graph of my juice fast weight loss (below), you’ll see that my weight dropped sharply at first and then plateaued a bit in the middle of the month.

When I got home from LA, I decided I would resume a pure juice fast for the rest of the month. In the week after my Mexican foodstravaganza, my weight started to drop really quickly again.

I have a theory about what happened, but I really don’t know. My thinking is that my body had adjusted to the juice fast and decreased calories and my metabolism slowed. That’s when my weight-loss plateaued. It makes sense that the body would slow down and go into preservation mode. When I went to LA and ate a 100% Mexican food normal diet, my body probably thought something along these lines, “ok, it looks like we’re not actually in starvation mode, so we don’t have to worry about slowing down the metabolism after all.” Of course, I went back on an all-juice diet for the rest of the month. So, basically I tricked my body. My weight dropped sharply at the end of the month. That’s my theory anyway. I’m sure someone reading this can correct me.

Juice Fast Weight Loss Total

I mentioned in my first juice fast post that I wasn’t doing this juice fast for weight loss. I knew it would happen, but it wasn’t my motivation. Still, I tracked my weight because a lot of people were interested in that aspect of the juice diet. I’m 6’2″ and started the month weighing a pretty fit 171 lbs. I ended the month weighing 160 lbs. I lost 11 lbs in 29 days. You can see a graph of my weight loss here. Click the image to enlarge it.

Juice Fast Weight Loss

I was pretty surprised to have dropped 11 lbs so quickly. I’m a pretty skinny dude, a runner and a mountain climber.

When I started off, I thought I wouldn’t like even losing 5 lbs, but I have to admit that I enjoy feeling lighter on my feet. I’m excited to see how weighing 160 lbs impacts my running and my climbing. I’ll post an update about that. I’m also curious to see whether I’ll maintain this new weight or drift back up to my “normal” weight. I’ll let you know about that, too.

If you’re thinking about going on a juice fast in order to lose weight, I don’t know if it’s the best approach. Juice fasting is extreme, and I’m not sure it’s even healthy for everyone.

I would suggest people talk with their doctor before taking on a juice fast, and aim for a fitness plan that isn’t so extreme. Extreme regimens aren’t sustainable over the long run, and you’ll probably be better off making small lifestyle changes that you can maintain forever. Building healthy habits is a much better goal, in my opinion.

Going Forward

Often times, I take on a monthly experiment with a specific goal in mind. I did the Stop Working Late experiment  because I wanted to stop being a workaholic. It worked, and that’s been great, but the Juice Fast experiment was different.

I wasn’t trying to change a habit. I did a juice fast mostly out of curiosity.

Overall, I have to say that I really enjoyed it. Drinking fresh fruit and vegetable juice made me feel great. Playing with my fancy new juicer was a lot of fun, too. I have a soft spot for gadgets, and this one was easy to justify.

So, am I going to continue juice fasting? No, but I am going to keep juicing on a more limited basis.

Juice fasting is hard, and extreme, and kept me from running. Juicing is something I’m still really excited about.

I wasn’t getting nearly as many fruits and veggies in my diet before doing this juice fast. Consuming more healthy foods is something I’m going to keep doing going forward. Instead of juicing every day, I’m planning on making juice a few times a week. Instead of juice for every meal, I might drink juice once or twice a day.

An extreme lifestyle can be fun sometimes, but I prefer to take a more balanced approach. I’m looking forward to going on a nice long run and  enjoying a super burrito from my local taco truck. In fact, I think I’m going to do that right now. 🙂

  1. hi! I am on my 4th day of a juice fast and I feel great, however, I am seeing no weight loss? I love getting all these veggies and fruits in because I normally don’t but I was wondering if I am not seeing weight loss at day four, should i continue to 10 days or try a different approach?

    • I’m on my 3rd juice diet and This is day 4 with 6lbs gone. This is the first time I have lost so much so quick, but I think it’s because this is the fattest I have ever been.

    • My weight loss takes place in cycles. I will lose weight 1 day and not for 3. Then the next day i will lose 4 lbs. this went on for 45 days.

  2. I noticed what you are talking about by incorporating the cheat day. I was on my juice fast and on Saturday I cheated, however the weight came off even faster the next week, firs week was 4lbs, and the second week was 6lbs, trying to figure this metabolism boost out without creating any hardships for the digestive system.

  3. Greetings,
    I am starting my second juice fast in roughly 10 months. I was very active and despite being a bigger guy was very healthy into my mid 20’s. I began feeling run down all of the time and was diagnosed with a structural defect in my airway leading to obstructive sleep apnea. I will be on CPAP regardless of my size or BMI due to the condition. Once the slep apnea progressed my weight climbed even with diet and working out. My doctor asked that I drop some weight to ward off some of the OSA related issues.

    Last winter I watched Sick Fat and Nearly Dead. At that time my wife and I cut all meat from our diets 5 days a week. We do have the occasional slip when dining at work or dinners out, but largely only allow meat two days a week. I also went out and got a juicer. The first cycle I completed 10 days of juice only followed by two weeks of plant only diet. In 24 days I dropped 30 pounds. I maintained a 25 pound weight loss there after.

    The Doc wants to see another 25-30 pounds off in the next 6-8 months. I came home and broke out the juicer again on a daily basis. I am three days in and have dropped 5 more pounds. I agree that this is a great way to drop the pounds quickly. I also agree that this is not something for everyone or the “safest” way to lose the weight. I hope to drop the weight as suggested by the doctor then maintain the weightloss with healthy choices and have a more active lifestyle.

  4. I did a 45 day juice fast and lost about 60 lbs. my bp went from 180/110 to normal. My cholesterol went from 320 to completely normal. My sugar also went back to normal. I kept the weight off for two years, until I got married. I put back on about 25, but i am on day 3 of my next 30 day fast. I, like you, add almonds to my diet. Salted almonds actually, as i feel bad if I dont have salt. It also put my autoimmune disease into remission.

  5. hello…done with my 7 day juicing experiment…was actually suppose to do 15, but I caved in..i am STARVING! well it feels like it, headaches, weak…very tempted to eat, was sniffing a lot….thought it made things easier, but it did not. It started out with a colon problem, constipation, although I was not aware to this cleanse. I must admit the first day almost killed me, but that had something to do with my idea of letting food go altogether, so it was a mental thing, second day and on..wonderful, I lost 9 pounds in 7 days..my cleanse was grape juice with lemon and teas…all kinds of teas. I love food, the smells, taste and its probably why Christmas baking was not good..i could not taste my cookies! I would suggest NOT doing this at Christmas, but is this possible and good? DEFINITELY ! I will jump back on the bandwagon in the new year, but this time I will look at broader type of ingredients, this one lacked vegetables, flavor! after losing 9 pounds and feeling better, I am also going to be doing serious changes to my diet. WHY? because I am worth it! Joyeux Noel!
