Student Question:
What are the most common dynamics in the body that prevent people from losing weight? What can practitioners affect that is most likely to actually succeed in supporting weight loss (assuming they want to lose a moderate amount, 20 lbs)?
SAFM Response:
Great question! Indeed, there will be many clients that come to us with the goal of losing a significant amount of weight. It is critical to teach people that the body views excess weight as an assurance against an uncertain future. The body will naturally increase adipose tissue if it feels our survival is being threatened. Weight loss will often be natural (and sustainable) when sources of stress (emotional or physiological) and inflammation are addressed. Forcing weight loss on its own, independent from addressing root causes, will not only likely be temporary but will likely cause new body weight reset points that are progressively higher (e.g. via calorie restrictive dieting). Setting proper expectations that weight loss is often the last perceived benefit of addressing the root causes of disease is, of course, critical for patient engagement, commitment, and persistence. You might want to experience this rich video on overall weight loss myths, misconceptions, and truths for practitioners through the functional medicine lens.
Before we dive in, please note one important consideration: clients with significant adiposity will also often have significant toxicity (as a result of the obesogenic effect of many endocrine disrupting chemicals). Many toxins are also stored in body fat, and ongoing toxic overload can actually be a root cause as to why they are having issues with overweight. Therefore, we don’t want to promote significant weight loss until we are sure detox pathways are well supported. Read more about the important steps for detoxification down below.
The most common reasons people struggle with losing weight are hormone-mediated and ultimately driven by (what else?!) Crap Food, Toxins, and Stress. Hormonal drivers include insulin resistance, hypothyroidism, estrogen dominance, and chronic stress.
Insulin resistance – both a high glycemic diet and chronic stress can increase the glucose load on the body. Over time, increases in blood sugar can lead to insulin resistance. In this case, cells are suffering from low energy, organs and the cardiovascular system are suffering from too much sugar, and the body is storing more and more fat. You want to check both Fasting glucose and HbA1c to get keen insight. However, usually years before fasting glucose or HbA1c begin to rise at all, fasting insulin begins to rise and will be suboptimally in the upper half of the normal reference range. This marker is widely available (at least here in the US) and can be proactively used to form a more complete picture of insulin sensitivity and glucose handling dynamics. This topic is addressed in great depth in SAFM’s clinical course Reversing Metabolic Dysfunction (included in our practitioner training program). Some strategies to address insulin resistance are:
Hypothyroidism – a sluggish thyroid can cause sluggish anything. Fatigue can result in moving less and sluggish metabolism can cause weight gain. Importantly, you must check a full thyroid panel – TSH, Free T4, Free T3, Reverse T3 and thyroid antibodies (TPO and TG) to look for various types of hypothyroid function (note that sub-clinical hypothyroidism can still have *dramatic* effects). You may find autoimmune (Hashimoto’s), nutrient-impaired (e.g. low T4 from insufficient iodine), stress- or sickness-impaired (e.g. increased degradation of T3 and deactivation of T4 to Reverse T3), and/or inflammation-impaired (e.g. poor conversion of T4 to T3) hypothyroid function. This topic is addressed in great depth in SAFM’s clinical course HPATG Axis: Adrenal/Thyroid Balance and Dysfunction.
Sex Hormone Imbalance, such as estrogen dominance or testosterone deficiency – a common issue in both men and women. Testosterone is important for many functions including libido and joint health, and it is well-known to be important for building muscle and decreasing body fat. Testosterone can be low due to stress, excessive exposure to estrogen, or excessive alcohol intake, for example. Deficiency can lead to low motivation, irritability, insulin resistance and weight gain. Much of our androgens are produced in the adrenal gland, so if the adrenal gland is busy pouring out stress hormones, testosterone production can suffer. Cortisol can also block testosterone receptors. In addition, with excess body fat, adipocytes may lead to excess estrogen and low testosterone because adipose tissue is endocrine tissue and can convert androstenedione and testosterone into strong estrogens via aromatization.
Estrogen dominance is a common disease dynamic that can lead to symptoms such as PMS (usually with cramps), heavy, lengthy, clotting periods, and stubborn weight gain. Most often, estrogen dominance is caused by imbalance in estrogen metabolism or clearance or increased estrogenic load from endocrine disrupting chemicals (pesticides, herbicides, parabens, phthalates etc.). A good opportunity in this case would be to clean up personal care and cleaning products and eat as much as possible 100% chemical-free and, ideally, organic.
Stress! Chronic stress unpins all of the above dynamics and, as such, is often a major driver of stubborn, excess weight. Cortisol is a catabolic hormone which is released under stressful conditions, breaking down muscle to generate blood sugar in the process of gluconeogenesis. It does this, while simultaneously increasing insulin resistance. High cortisol may also promote intracellular hypothyroid function. Many people trying to lose weight inadvertently increase their cortisol with excessive aerobic exercise or insufficient calories for example. Of note, sustained low cortisol due to prolonged stress or burnout can also reduce thyroid action via reducing thyroid hormone receptor function. Sources of stress that may lead to trouble losing weight include:
Food sensitivities can cause symptoms of all kinds, including general inflammation and weight gain. First try eliminating gluten and dairy 100% for 4+ weeks as a trial. A further elimination diet may be tried from there, and if appropriate, consider food sensitivity testing. None are comprehensive but total IgG with complement (not IgG4) or a combo IgG/IgA are best to help eliminate false positives. There is a rich post here on food sensitivities as well. This topic is addressed in great depth in SAFM’s clinical course Immune Function, Loss of Tolerance, and Hypervigilance (included in our practitioner training program).
Many toxins are stored in adipose tissue and can be a common reason for weight loss resistance. Common toxins we are exposed to are endocrine disrupting chemicals (personal care products, cleaning products and food packaging), pesticides, herbicides, fungicides, VOCs, heavy metals and mold. We not only need to reduce exposure, we often need to remove stored residual toxins from the body as well. For example, mold is a toxin that can lead to weight gain or trouble losing weight. Getting it out of the body will only help marginally if one is constantly being exposed. Full healing can’t take place until the person is removed from the toxic/allergenic environment sustainably and detoxification is supported as needed to enable clearance. This topic is addressed in great depth in SAFM’s clinical course Toxicity, Detoxification, and Heavy Metals (included in our practitioner training program).
Regardless if it’s a driving root cause or not, it’s important to be mindful of the fact that as we lose weight, we free up toxins from adipose tissue and put them back in circulation (more here and here). This dynamic is seen with weight loss via diet and via surgery. This can cause an increase in physiologic stress (and cortisol), which will in turn, slow weight loss.
So, before any intensive weight loss efforts, there are a few important things to ensure before proceeding:
Finally, it’s also important to take breaks from intense weight loss efforts to work on healing the gut intermittently. All the toxins released can damage the GI tract lining, so to avoid causing other downstream issues, it’s important to take some time to heal the gut.

Do you recommend starting the binders before actual weight loss begins?
Yes, this would be quite prudent. You also want to ensure satisfying, easy to pass bowel movements to support proper detoxification.
Is it safe to recommend a methylated B complex to everyone without regard of knowing their MTHFR status? What harm would it cause to take a methylated B complex if it is a water soluble vitamin? When would it be necessary to check MTHFR? ( I know this may be a loaded question) but my understanding is that the MTHFR mutation will impair the metabolism of B vitamins and that because B vitamins are water soluble, there is a lower risk than the fat soluble vitamins to over dose. With that said, is there any need to check MTHFR status if a person is willing to take a B complex? Thank you!
No, methylated B complex, particularly methyl folate, may not be beneficial for everyone. To your point, some people may have a mutation in MTHFR or other genes coding for enzymes involved in the methylation cycle. On the one hand, this creates an increased need for B vitamins and increased sensitivity to excess methyl groups. Dr. Ben Lynch is a great resource on this topic, and we recommend visiting his website to learn about the details:

How long should one take binders for?? Would spirulina or astaxanthin work like chlorella as a binder?
The length of supplementation with binders will certainly vary from client to client. It can last from 2 weeks to 3-4 months. Pausing and changing the binders is an advisable strategy simply because different binders have an affinity to different toxins and to minerals, vitamins, and other nutrients.
Spirulina can be used instead of chlorella since it has similar properties. There are some differences though, that one should be aware of – this well-referenced blog post by Dr. Axe is a good place to start exploring those:
https://draxe.com/nutrition/spirulina-benefits/
Astaxanthin is a carotenoid with strong antioxidant properties and is sometimes paired with binders to offset oxidative stress, a natural effect of the upregulated detoxification process. Here are a couple of articles that may be of interest to learn more about this natural compound:

Hello,
When speaking to using natural food, such as an increase in fruits and veggies, as a binder (specifically applesauce – to be used for the effects of pectin), do you still recommend taking away from meals and supplements or is this not necessary as they are all part of a natural diet? Thank you!
Great question! No, it is not necessary to separate this type of food from the regular food that is consumed, as this one is simply increasing the amount of natural fiber and pectin that is part of the whole food. Most other, more targeted binders that are typically taken as a supplement to the diet should be taken away from food and supplements and one should always start ‘low and slow’ in order to avoid any possible negative effects due to over-mobilization of toxins or sensitivity/allergy reactions to the supplement.
When you say “take breaks from intense weight loss efforts to work on healing the gut intermittently,” what does that look like in your practice?
When a client is strict about their diet, exercise, and relaxation and supports liver detoxification pathways simultaneously, this will bring weight loss. Approximately after 20-25lb weight loss and depending on each unique client and their specific journey, one would want to focus on more physical rest, supporting gut health with mucilaginous herbs, pro- and pre-biotics, and possibly even glutamine, or with a course of drinking bone broth daily for a couple of weeks and turn down the efforts to upregulate the liver detoxification to make space for the gut mucosal lining to regenarate. Keep in mind that all healing happens in the parasympathetic nervous mode, and processing toxins in the body requires energy and may negatively impact the gut microbial flora.
In terms of weigh loss, how does eating late night contribute to weigh gain? can you provide me with some insights?
The recommendations often made by Tracy is that, if you are trying to loose weight, do not eat 3 good hours+ before bedtime.
I would really like to have an accurate understanding of this mechanism.
Thank you.
A lot of dis-ease start with poor eating hygiene, this was discussed at length in this FB live:

How do we ensure good bile flow? Is there a way to check this?? Does having the gallbladder removed effect detoxification pathways then. Thank you
Good eating hygiene and food choices that include high-quality protein and fats and also bitters that support bile formation and flow, as well as avoidance of processed foods (those are often rich in oxidized fats and an overabundance of sugar and fructose) that can negatively affect liver function are at the foundation of ensuring good bile flow. Please also refer to the paragraph on toxicity above as this can have a significant impact on bile flow as well.
Alas, there isn’t one test to check the bile flow quality, but it can be noted on a liver panel and on a comprehensive stool test once the hepatobiliary congestion has been at play for a while.
The gallbladder per se doesn’t impact detoxification pathways that take place in the liver, however, the steady bile trickle into the GI tract does have consequences that eventually can impact the body’s ability to process toxins. You may be interested in these additional posts:

My client who had radioactive iodine therapy 30+ years ago and has been on Synthroid ever since has lost 30 pounds over 6 months with diet changes, detoxing, and gut healing but has not reached her weight goal and has hit a plateau. I’m wondering if she should approach her doctor about getting off Synthroid and on to a natural compounded T4/T3?
First, congratulations on your client’s weight loss progress! Yes, as you know Synthroid is a T4 only drug and many patients using it can still suffer hypothyroid symptoms even with normal TSH measurement. Thus, checking your client’s full thyroid panel could be helpful here, and consulting the doctor about the switch to a natural compounded T4/T3 does make sense. Also, keep in mind the interconnectedness of the cortisol levels and the intracellular availability of the thyroid hormone.
