doTerra Slim and Sassy: Can Essential Oils Help You Lose Weight?

doTerra Slim and Sassy: Can Essential Oils Help You Lose Weight?


Oh, Essential oils. You’re getting to be something you’re not….especially with all the claims that companies are making about you. 

This needs to stop!

I’ve already done a post on Young Living essential oils, but doTerra has a whole other product line for weight loss that I felt would be better in its own separate post. Because how else would I be able to showcase their unbelievably tacky-sounding ‘Slim and Sassy’ line?

HEY doTERRA! The 80’s called, they want the word SASSY back!


Okay, let’s do this. 

doTerra Essential Oils

So, like in my Young Living post, I’m going to focus solely on the nutrition products that doTerra offers. But first, a word about essential oils.

Essential oils have been around for centuries, and while some people want to believe that they cure diseases and sanitize against coronavirus and can replace your depression meds (do NOT do that), those people are fucktrumpets who don’t science and certainly don’t have your best interests at heart. They want make money by selling a sham product, often using fear of conventional medicine and ‘Big Pharma’ to convince you that ‘natural’ is better. Except it’s not, because 1. the poison mushrooms in my backyard are natural, I’m not eating those and 2. essential oils can sure as hell be harmful and even toxic to humans. 

Take THAT, Big Pharma!

Oh, wait…

There’s also no evidence that supports any of the claims made about the consumption of essential oils for anything. Sure, sniffing lavender might subjectively calm you, but holy shit, do NOT stop your cancer treatment for a ‘natural essential oil regimen.’

This is a great time to let you all know that actual research suggests that people who eschew conventional cancer treatments in favor of alternative ones have a much greater risk of death. 

doTerra markets its oils as being pure, therapeutic grade, and natural. But who cares how pure your oils are, if they don’t do what you say they do? Actual results trump purity, am I right?

Unlike Young Living, which I have to say is shady AF, doTerra actually has a ‘research’ page on its site, which made me very excited…until I clicked on it.

There is no research posted on the page, only a lame-ass blog that summarizes studies – all positive for the products, of course, and a disclaimer:

Many of the referenced studies are preliminary, experimental studies and further research is needed to gain a greater understanding of the findings. Essential oils may have drug interactions, patient contraindications, or adverse effects that cannot be evaluated using experimental research results alone. If you are interested in using essential oils for any health concern, consult with your healthcare provider first.


So basically, they’re telling anyone who bothers to look that the ‘science’ they use to back up their claims is mostly based in animals and for the most part, not at all conclusive. Even more than that, they (correctly) say that essential oils can be harmful, but then doTerra turns around and lets anyone at all sell this shit to pretty much whoever wants to buy it.

This is one of my biggest complaints about nutrition MLMs – nutrition is a science, and weight loss is complex. Salespeople and ‘coaches’ are usually untrained and woefully unprepared to judge who should NOT be buying their products, and they’re so stressed about selling their crap and making emerald fucking triple diamond unicorn’s ass level that they don’t give a shit about any of that anyhow. No okay.

doTerra Slim and Sassy Weight Management Line.

As I mentioned before, the doTerra weight management product line is called ‘Slim and Sassy.’ 

The biggest package offered is the ‘New You Pack,’ at $265. It contains 40 servings of TrimShake, a Lifelong Vitality Pack whatever the fuck that is, and four Slim and Sassy ‘metabolic blends.’

There’s also a Slim and Sassy ‘metabolic gum’ that you can add to your pack.

Just so you know, my bullshit radar is going off strong as I write this. 

Right here, I feel the need to stop everything and talk about the word ‘metabolic’ and how MLMs use it – or should I say, ‘misuse’ it to make sales.

Metabolism is complicated, but the most important things you need to know right now about metabolism aren’t too hard to understand.

They are:

  1. No supplements can elevate your metabolism high enough or for long enough to cause appreciable weight loss. Even if you eat a mouthful of chili peppers, you might burn 13 extra calories a day. Not worth it. All those ‘fat burners’ that MLMs sell? Worthless.
  2. No essential oils cause a rise in metabolism. Think about this: you’re putting 4 drops of oil into a glass of water, and drinking it. Thinking rationally, does that seem like something that would really raise your metabolism? No. No, it doesn’t. 
  3. If metabolic or ‘fat burning’ supplements worked, everyone would be thin.
  4. The only things that raise metabolic rate are increased muscle mass, fever, moving more, and consuming more protein (don’t go eating a protein-only diet now)
  5. MLMS love to talk about metabolism, hormones, and ‘cellular’ anything (ie: feeds your body on a cellular level is a common phrase) because they think these words sound sciencey enough to convince potential customers that what they’re saying is legit. Don’t be fooled.
  6. I wrote a blog about metabolism and weight loss in which I break down the science in a way that everyone can understand. Read it here.

Back to the metabolic gum, doTerra claims it has ONE drop of Slim and Sassy oil in every piece! WOW!! But even worse than that, the company claims that this gum can ‘promote healthy metabolism’ and ‘help manage hunger cravings,’ both of which are complete and utter bullshit. 

I want someone – anyone – to tell me how this shit fucking essential oil gum can ‘promote healthy metabolism.’ Actually, I want to know what ‘promoting a healthy metabolism’ even means, because to me, the phrase is meaningless. It’s nebulous and vague. Shit like this enrages me because doTerra is using pure fuckery to sell complete garbage. 

I hate that!

doTerra TrimShake.

The TrimShake is a super low-calorie – like, 70 per serving – shake that contains two ‘special’ ingredients. The first is EssentraTrim, which has been supposedly proven by research to help lower the stress hormone cortisol.

High levels of cortisol can facilitate fat storage and mess with our hunger hormones, so we definitely don’t want that to happen. But what is EssentraTrim, anyhow?

I went looking for answers, and unfortunately I didn’t find many.

What I did find is that EssentraTrim is likely composed of ashwangandha, an adaptogenic herb. 

Ashwagandha does appear to reduce cortisol levels in humans, but like this article indicates, more research needs to be done on dosage and the herb in general. 

There is no ‘ideal’ dose, so we don’t know if TrimShake contains enough active ingredient to even have an effect. 

TrimShake also contains Solathin, a potato-based protein that was launched in 2011. For something that’s supposed to be innovative and effective in reducing appetite, I’ve never heard of it. 

Lastly, a 70 calorie shake is not a meal…it’s about 430 calories short of one. #fail.

The metabolic oils, well, I think we’ve gone over this already. Slim and Sassy oil contains Grapefruit Peel, Lemon Peel, Peppermint Plant, Ginger Root, and Cinnamon Bark essential oils, none of which will do sweet fuck all for your metabolism. 


I’m sure there are other oils that doTerra claims can help your metabolism – like their fennel oil – but again, NOPE.

I wonder how they get away with using these claims to sell their stuff. It’s absurd.


doTerra Lifelong Vitality Pack.

The Lifelong Vitality Pack is basically three products of your choosing. The options include a multivitamin (you probably don’t need one – here’s my post about multis here) with ‘whole food’ ingredients and digestive enzymes, digestive enzymes on their own (you probably don’t need these), an omega-3 and essential oil supplement, antioxidant supplements, a probiotic (probably useless), and a supplement called ‘Mito2Max,’ for “healthy cellular energy production.” 

According to doTerra, “Mito2Max supports optimal mitochondrial function,* aerobic capacity, and stamina naturally without the use of harmful stimulants”

There’s those sciences-sounding words again! MITOCHONDRIA! 

One of the active ingredients in Mito2Max is L-Carnitine, which is readily available in foods like meat, dairy, beans, and eggs. Our bodies make carnitine, too. It’s used for energy production, and even though muscle heads and athletes want to believe that carnitine improves energy and stamina, the research says otherwise. It does seem to improve sperm quality, just in case you’re looking for that.

The supplement also contains ashwangandha and other poorly researched herbs that probably do nothing. 

I’m beginning to see a pattern here. Are you?

I’m so done. doTerra, you suck.

Just like Young Living, doTerra makes a lot of big promises and claims that it can’t back up with peer-reviewed, human trials. It uses ingredients that have been invented by food scientists for companies just like this one, which sell to unsuspecting and desperate people looking for the next best weight loss thing. 

I can assure you, this isn’t it.
