Do I Need to Detox or Cleanse? Print

Global CalgaryCleanses and detoxification regimens were popular in the early 1900’s but have recently resurfaced as trendy with push from celebrities, so called “health practitioners,” documentary films and supplement companies.  But do the claims of weight loss, feeling better and improved health, really stand true?

What is a detox or cleanse?

fruit and veggie juicingThere is no one single way to describe cleansing or detoxing.  For some this may be drinking only a concoction of water, lemon juice, maple syrup and cayenne pepper for days.  For others this may be giving up a wide range of foods and turning to fruit and veggie juicing cleanses.  Other common cleanses involve eating a restricted list of foods and taking a wide range of supplements, shakes or laxatives.  There are also radical regimes that include colon irrigations (a procedure similar to an enema).

Should we all be cleansing and detoxing?

There is no scientific data that supports the claims made by detox and cleansing diets. Proven scientifically, humans are fully equipped with the best detoxification system. The human body draws nutrients for the foods that we eat, and excretes wastes not needed. Organs work together in waste removal: the liver removes waste from the bloodstream and prepares it to be sent to the kidneys for disposal of the urine. The large intestine does not need internal cleansing since it works to reabsorb much needed water and minerals as the wastes pass.

Can a cleanse help with weight loss?

Any diet plan can create weight loss if calories are decreased.  Remember that anyone can lose weight temporarily but can you sustain it?

It has been claimed by promoters of cleanses that if weight loss has stalled for you or if you are trying to kick start weight loss that cleansing can help.  The theory is that a specific diet will remove toxins out of the body allowing your body to function better and lose weight more efficiently. This is simply not true. Remember that we have the kidneys and liver as natural detoxification organs. Having more bowel movements does not typically increase weight loss since most of the calories in food is absorbed before it reaches the colon.

Taking laxatives and herbal laxative products can falsely make it seem like you have lost weight because of dehydration and water loss. Also remember if your cleanse takes out carbohydrates, similar to low-carb diets, there can be an initial temporary water weight loss (after all one gram of carbohydrates stores about three grams of water on the body).

Could there be some benefits of cleansing?

Many detox programs encourage eating lots of fruits and vegetables, which are high in water and fiber and may help move things smoothly through the gastrointestinal tract, and this tends to make people feel better. Taking a temporary break from caffeine, alcohol and refined sugars-as is prescribed by most of these plans-may not only eliminate energy crashes sometimes associated with these ingredients but also could help people realize just how much “junk” you normally consume. In this way, detox periods may inspire longer-term healthy changes.

What are the risks or potential negative effects of cleansing?

Colonic irrigations done improperly can seriously injure the large intestine and create an imbalance for the friendly or good bacteria found in the gut. Other “safer” plans (those that promote eating only select, nutritious foods) may cause fatigue or dizziness if they don’t supply adequate calories. If severe calorie restriction is sustained for more than a few days, the body may sense impending starvation and release stress hormones, a response that ironically may increase circulating toxins. Finally, the enhanced energy or euphoria that detox dieters often report may be the result of surging stress hormones too. Evolutionarily, it makes sense: a “fight or flight” response drives hungry animals to seek out food aggressively. An adrenaline-charged drive is short-lived, and with prolonged calorie restriction, the body powers down to conserve energy, ultimately slowing the metabolism.

What is the bottom line when it comes to cleanses?

If you’re a healthy adult, living on vegetables and water for a few days isn’t likely to do you harm—or much good. If you operate on the mode of ‘live today, detox tomorrow’ you are fooling yourself. Optimizing your body’s natural detoxification systems is best achieved by the everyday boring messages you’ve heard before (eat well, drink water, get enough sleep and exercising regularly). 

You mention there is a healthier way to think about cleansing?

You now know that I am not an advocate for traditional cleanses mentioned above.  But like any fad diet and trend there are always good lessons that can be learned.  If the concept of cleansing is appealing to you on some level why not consider thinking about it in a healthier way that really makes a difference for your health.  Try this challenge:

Do a MEAL cleanse rather than a diet cleanse.

Write down what you eat for 3-7 days and pick out one meal that strikes you as the one that needs some work.  Maybe this is your breakfast, mid-afternoon snack or evening snack.  Out with the old and in with the new.  If every day you replaced your vending machine or processed food afternoon snack and instead chose a healthy option rich in whole foods and sustained this over the long term.  This would indeed improve wellness, energy and healthy weight management.

Andrea and her team provide highly knowledgeable, compassionate, and real world support to my clients who require assistance with food lifestyle.

Adele Fox, Psychologist
“This is the first time I feel satisfied; my cravings have diminished dramatically and I have a whole new relationship with food. I am eating guilt-free for the first time in my life. My energy has also dramatically increased and I feel great!
Rhonda Jenkins, Nutrition Counseling Client
“The Dieticians at Health Stand Nutrition help you to take action on the science behind eating well by making it practical, understandable, and fun. Their office is cozy and not at all clinical or intimidating. I felt like I was sitting down with a really smart, caring friend who wanted to help me make the best choices for my lifestyle and food preferences. Andrea and her team really are the best in the business.”
Marty Avery, Nutrition Counseling Client
“I have come to think of the program as a one stop shopping excursion for everything one needs to know about creating a joyous relationship with food and our bodies. In a single word, the course has gifted me with freedom from the punishing rigidity of disordered eating, old stories that never were true, and body dysmorphia that did nothing but make me lose sight of a body that has done everything I've asked, despite my careless dismissal of her needs. Now when I look in the mirror I find myself shifting from harsh criticism to gentle gratitude.”
Lynn Haley, Pursuit of Healthiness Online Course Participant
“I spent 3 hours when first diagnosed with type 2 diabetes. I learned more from my Dietitian about food in those 3 hours than I had learned in all the years of my life. I also love the newsletter, there is always something to learn.”
Peter Whitehead, Nutrition Counseling Client
“I didn’t realize how strong my “diet mentality” was, and all the rules I had in my head about food. I was in a cycle of reward/punish/binge/cringe. I booked with your business very reluctantly, on the repeated advice of my doctor, to get my slowly rising cholesterol levels in check. I thought I knew everything about food, and my behaviour with food, but I was definitely re-schooled. My weight is creeping down, I feel good about my diet, exercise, body image, and lifestyle.”
Amy Floyd, Nutrition Counseling Client
“Thanks Andrea for an amazing presentation, I have heard all positive remarks from attendees and the evaluations show the same sentiment. It is really gratifying when a speaker does their “homework” and weaves in our profession’s day to day challenges within their content, you did an awesome job of this! You truly took the “die” out of Dietician! Your information on healthy eating and simplifying how we can work towards this as we are all so busy really hit the mark. Andrea connects very well with her audience; she is energetic, funny, and very approachable.”
Carole Ann LaGrange, Transfusion Medicine Safety Officer

Event Planner for Laboratory Diagnostic Imaging Annual Event

I am a family physician who sees patients with a myriad of eating concerns – from wanting to know how to plan healthy meals for active families, to weight loss, to eating disorders, and so on. I cannot recommend the Health Stand team highly enough. I have worked with (and been to!) other Dieticians in the past and too often find that they just ask for food logs and make suggestions that are easily obtained online or in books. The Dieticians at Health Stand offer much more than just telling clients what they “should be eating.” In contrast, the team really does more of a counselling practice, and they work hard to help their clients learn more about why their eating habits may be off track and not optimal for them, as well as helping people to effect change at a deep level that, most importantly, is sustainable for lifetime health.”
Dr. Deb Putnam, Family Physician

Nutrition Counseling Client & Referring Physician

“I am a busy mom, with kids in high level sports, working full-time downtown, and running our home acreage outside the City. I now have the knowledge and tools I need to plan for and manage the chaos of meal planning.”
Gillian Gray, Pursuit of Healthiness Online Course Participant
“As a construction company, we select speakers who can relate to our industry and its employees. Andrea’s message was delivered with humor and empathy. She makes people feel as though they can make changes without leaving behind every favorite food. Andrea focused her presentation on healthy eating as a way to keep energy high throughout the day. This message and the way it was delivered resonated with our predominantly male, blue collar culture. I would highly recommend Andrea as a speaker for groups such as ours. She will get your message across without alienating anyone in your audience – which is a huge hurdle when trying to introduce a wellness program in the workplace!”
Stephanie Wood, HR and Safety Manager

Fisher Construction Group, Burlington, WA

I found my Dietitian warm, funny, and skilled at teaching nutrition concepts without the overwhelm. The general approach of each session was to mix science with emotion, which was exceedingly effective in helping me shift my perspective on food from one of anxiety to one of joy and curiosity.”
Erin Kronstedt, Nutrition Counseling Client
“Excellent presentation! What a refreshing change to have a speaker inspire rather than “lecture” about nutrition. Your captivating stories, tips and overall approach to healthy eating uplifts and puts people at ease. It was great to hear we don’t need to strive to be perfect eaters, and that small changes really can make a difference in how we feel and in our health. Thanks to Andrea, we have solutions to our everyday nutrition challenges that can actually work in real life!”
Tina Tamagi, Human Resources

ARC Resources Ltd.

“Had I not joined this course I would have struggled with no focus, low energy, and mindless eating. Andrea is an excellent teacher and motivator. This is not just a course, it is a nutrition club with mentorship, support, and connections with other people with similar situations.”
