8 Week Detox Program for Weight Loss

Because knowledge is power

Imagine waking in the morning feeling refreshed and ready to start the day. You pull on your favorite jeans, the ones that used to be in the back of your closet. The ones you know make the guy at the coffee shop look twice. 

You eat a delicious breakfast you KNOW will make you feel great and give you lots of energy to kill it at work, drop off the kids and run all the errands, or be your most creative self writing that screen play.

These are just some of the real-life stories from past clients.

What does your future hold for YOU?

Want Results Like These?

I've lost 30+ lbs!

Honestly, I wish I could give Liz more than five stars. Where do I begin? She's extremely kind, knowledgeable, and has helped me establish incredible eating habits. 

As of now, I have lost 30+ lbs with her help. And that was just over the course of four-ish months?

Overall, I cannot recommend Liz and her services more highly. If you want to figure out how to diet effectively and take control of your physical/digestive health, look no further!

I had to buy new pants!

My blood sugar was high and my doctor warned me that if left unchecked it could become diabetes.

Liz made it super easy for me to identify and cut out the problem foods. To my surprise, I wasn't hungry or felt like I was missing out.

Now, my blood sugar is healthy, I feel better, and I lost FIFTEEN pounds. I had to buy new pants!

Client Stories

I had constant digestive problems  and muscle pain.  Today my fibromyalgia is completely gone.

I started seeing Liz a couple of years go because I had constant digestive problems, had significant muscle pain and was often exhausted -- never mind being totally anxious.

I'd been diagnosed with celiac disease (after seeing several doctors over 11 years) four years earlier and was gluten-free and dairy free but that didn't seem to be enough. Then I developed fibromyalgia. I was so depressed!

Liz put me on the GAPS diet and counseled me patiently through developing a variety of meals and foods that do really well for me.

She has me taking nutritional supplements, so that I no longer have those depressingly low vitamin levels. 

Even before my gut healed, I realized that the fibromyalgia was abating, and today it is completely gone.

My family and I are so grateful to Liz.

I have been able to resume all my activities, can plan on going on outings with my new found energy, and have developed a new body with my workouts.

What a difference! Thank you, Liz. 😍

I was exhausted  from seeing doctors who didn't understand my health challenges. Within two weeks of working with Liz, my lab numbers began normalizing for the first time in a decade.

When I began working with Liz Voosen, I was exhausted from years of consulting dozens of allopathic and holistic practitioners who were unable to successfully understand my health challenges.

She listened patiently to my lengthy story and responded with compassion and gentle suggestions that I had never considered before.

Within two weeks of trying just a few of her dietary and lifestyle tips, my lab numbers began normalizing for the first time in a decade.

Liz has provided refreshing perspectives about how healing both the body and mind through food can work even for someone with extensive sensitivities.

From the start, she has been willing to tailor a plan that respects my sensitivities, and she always waits until I am ready to proceed to the next stage.

I have also enjoyed gleaning her biochemistry brilliance through explanations of how each nutrient supports each organ system. Learning nutritious and delicious recipes has been wonderful too.

As a deep listener who genuinely cares about how her clients want to look, feel, and succeed in the world, Liz demonstrates her commitment to supporting them in achieving their goals.

She has re-infused me with life, and I feel profoundly grateful for her guidance.

How much weight can i lose in 8 weeks?

This varies from person to person. On average, clients lose 10-15 lbs, but could be as little as 5 or as much as 30.

Your results are dependent on your level of commitment, on your starting weight and goal weight, your food choices, your activity level, your genetics, your stress level, etc. 

Clients who want to lose significant weight can repeat the 8 week program, switch to the "All Health Issues - 3 Month Wellness Plan" (if you decide you'd like to address other health issues as well), or the Maintenance Plan.

What if I want to lose more weight after the 8 week detox?

This is completely up to you!  Many clients who want to continue losing weight have mastered the foundations of the plan after 8 weeks, and switch to the Maintenance Plan. This plan meets once a month, to help keep you focused, minimize the dreaded plateaus, and address other issues. The Maintenance Plan is $175/month.

Do I have to weigh / measure / count points?

No! Not unless you want to :)

Occasionally, measuring to see what an amount looks like is advised until you are familiar with the ingredient. But it's just like with a recipe - you wouldn't necessarily add a handful of an ingredient if the recipe called for 1/4 cup. But after making it a few times, you might not measure it anymore.

will i be hungry?

No! Old-school reduced calorie diets just lead to yo-yo'ing and more weight gain. 

On the 8 Week Weight Loss Program, my goal is for you to feel satisfied and still lose weight.

will i be taking weight loss drugs?

No, not from me at least.

All supplements are natural herbs, vitamins, minerals, or nutritional ingredients. No scary stimulants. And no addictive substances.

is the 8 week detox program right for me? my health is complex.

My clients who are relatively healthy and who want to drop a few pounds, or kick off a larger weight loss, love the 8 Week Detox Plan. This plan is similar to the more intensive All Health Issues Plan, offered here, but only 8 weeks long and all of our time will be focused on weight loss and detox.

If you have chronic or serious health issues, the "Wellness Plan" is the one to pick. Check out this page for more details.

If you have additional questions, please call the office (323) 394-0848 or fill out the form below and I can help you pick which plan will work best for you.

Can I get lab work done?

Yes! Both specialty lab testing and standard blood tests are available for clients of Liz Voosen Wellness. These labs are for nutritional information and education.

Please see your primary care doctor for medical concerns.

Do you work with kids too?

Yes, Liz works with kids of all ages, in addition to adults.

Kids under 16 may benefit more from the "All Health Issues - 3 Month Wellness Plan", as their nutritional needs are different than an adult's. Please contact the office to discuss which plan is right for your kids.

Do you take health insurance?

Liz Voosen Wellness does not accept insurance, nor do we provide superbills. Credit, debit, and (often) FSA/HSA cards are accepted.

Can I use my FSA/HSA card?

Liz Voosen Wellness accepts FSA/HSA cards. It is up to you to verify what your plan will cover. 

Can you tell me more about you?

Liz Voosen has extensive training in nutrition, and has qualified as an FNTP, FDN-P, and CGP. She also is a certified RYT200 yoga instructor (a pandemic passion project).

Liz graduated Phi Beta Kappa with a BA from Washington University in St Louis, and her first job out of college was at the top-ranked Washington University School of Medicine, working in the new neurobiology department's research library and with their new medical journal. She has a lifelong fascination with science and medicine.

She also loves learning about the history of nutrition - everything from what our ancestors ate to sustainable, health-proven nutritional customs around the globe - and believes that sometimes Grandma knows best. 

Liz has a deeply personal interest in nutrition as well, which began when she got sick with celiac disease at age 19. This gives her great compassion and understanding for her clients with autoimmune and digestive disorders.

Liz lives in Los Angeles, CA,  with her family and their dog, Lila.

Do you offer online appointments?

Yes! Appointments are exclusively offered online using a secure, HIPAA-compliant video platform.

Clients from all over the world are able to meet with Liz this way. 

We love that this also reduces cars on the road, leading to a smaller environmental footprint, and a happier planet.

where is your office?
