It takes real Guts to go your own way.
If you struggle with fatigue/productivity, your gut or weight, and have tried dieting no no avail, then likely you suffer from a damaged metabolism. If your metabolism (fat burning) is broken, you will store body fat no matter what or how much “healthy food” you eat. Overeating, skipping meals, binging, succumbing to cravings for sweets or carbs… unfortunately all of these are signposts of and contribute to a damaged metabolism.
Have you ever wondered why some people seem to gain weight no matter how carefully they count calories, while others stay slim effortlessly? It turns out, the answer might be hiding in your gut microbiota.
Until I paid attention to my gut and changed my diet to increase healthy proteins and fats, removing processed chips and crackers, I couldn’t heal it. Thankfully, I lost and kept off 30 lbs, no longer suffer from a leaky gut, increased the diversity of my microbiota and can eat without pain or nausea. Thanks to joining the Biome Learning Center under Kiran Krishnan, taking his Microbiome Clinical Science Course and becoming a Microbiome Labs and Pendulum authorized practitioner, I can now effectively help my clients do the same, increasing longevity and healthspan.
Recent science is shifting our view of obesity from a simple “calories in, calories out” equation to something more complex: a disorder influenced by the trillions of microbes living in your large intestines, known as the gut microbiome. This isn’t about willpower or fad diets! It’s about restoring balance to your body’s inner ecosystem for sustainable weight management

What’s the Gut Microbiome (aka our Microbiota), and Why Does It Matter for Weight?
Your gut is home to a diverse community of bacteria, fungi, and other microbes that help digest food, produce fatty acids, vitamins, and even regulate your mood and immune system. When this community is in harmony (think of it as a thriving garden we cultivate with lifestyle and proper nutrition) everything runs smoothly. But when it’s out of whack, growing into the small intestine (which should largely be sterile) we get a condition called dysbiosis, and real problems arise.
In dysbiosis, it is found that harmful bacteria outnumber the good ones, leading to a leaky gut barrier. This allows toxins like lipopolysaccharide (LPS) to slip into your bloodstream, sparking low-grade inflammation throughout your body. Inflammation messes with key hormones like insulin and leptin, which control blood sugar and hunger signals. The result is that our body starts storing more fat, craves sugary foods, and resists weight loss efforts. It’s a vicious cycle: dysbiosis fuels inflammation, which leads to more fat accumulation, worsening the dysbiosis.
Key players in this situation are missing “keystone species” like Akkermansia and Faecalibacterium. These beneficial bugs help maintain gut health, but they’re often depleted in people with obesity due to poor diets low in fiber. When I got my first stool test in 2020 I had no detectible numbers of Akkermansia at all! Thankfully, I found a trustworthy company that offers supplements of this difficult to keep alive species and repopulated my gut.
The Power of Short-Chain Fatty Acids (SCFAs):
Your Body’s Natural Fat Burners
One of the microbiome’s superpowers is producing short-chain fatty acids (SCFAs) like butyrate, acetate, and propionate from fermenting dietary fiber. These are metabolic messengers.
SCFAs act like switches that turn on fat-burning mode. For instance:
-
Butyrate boosts leptin signaling, helping you feel full and improving how your body breaks down fats.
-
SCFAs increase adiponectin, a hormone that revs up your cells’ energy factories (mitochondria) and enhances insulin sensitivity.
-
In obese individuals, low SCFA levels mean reduced fat oxidation, higher risks for fatty liver disease, and type 2 diabetes.
The catch is that a Western diet heavy in processed foods and low in veggies starves these fiber-loving microbes, leading to SCFA shortages. Restoring them gently through fiber-rich foods can kickstart your metabolism without extreme calorie cuts.
GLP-1:
The Gut Hormone That Curbs Cravings
Ever heard of GLP-1? It’s a hormone released by your gut cells that tells your brain, “Hey, you’re full! Stop eating!” It also slows digestion, boosts insulin production, and helps to regulate blood sugar. Popular weight-loss drugs like semaglutide mimic GLP-1, but your body can produce it naturally, with help from your microbiome.
SCFAs from healthy gut bugs stimulate GLP-1 release. Keystone species like Akkermansia are crucial here. When dysbiosis hits, GLP-1 levels drop, leading to stronger cravings, insulin resistance, and easier weight gain. The beauty of microbiome-based GLP-1 is that it’s short-lived and natural, avoiding the side effects of long-term drug use. Focusing on gut health could be a gentler way to tame appetite and support metabolic recovery.

Metabolic Endotoxemia:
The Silent Inflammation Driver
Imagine tiny toxins from gut bacteria leaking into your blood and setting off alarm bells in your immune system. That’s metabolic endotoxemia in a nutshell. LPS from dysbiotic guts activates immune cells, releasing inflammatory chemicals like TNF-α and IL-6. These disrupt insulin signaling in muscles and fat tissues, promote bigger fat cells, and even mess with your brain’s satiety centers, making overeating more likely.
Studies show this inflammation can start before noticeable weight gain, suggesting gut issues are an early trigger for obesity. The good news is that fixing the microbiome reduces these toxins, calms inflammation, and improves how your body handles glucose and fats.
Proof in the Pudding:
Losing Visceral Fat Without Dropping Pounds
A fascinating study highlights how powerful microbiome tweaks can be. In a 90-day trial, participants taking prebiotics and probiotics saw a 35-37% drop in visceral adipose tissue (the dangerous belly fat around organs) without losing overall weight or changing their diets much. This fat reduction came with lower inflammation markers, proving that gut health influences where and how your body stores fat, independent of calories.
This “terrain-based” approach shows that obesity isn’t always about eating less; it’s about changing the body’s internal environment to favor fat loss.
A groundbreaking mouse study demonstrated the causal role of the gut microbiome in obesity. Researchers transplanted fecal microbiota from obese mice (which had a higher Firmicutes-to-Bacteroidetes ratio and greater energy-harvesting capacity) into germ-free mice raised without any bacteria. These recipient mice gained significantly more body fat and body weight compared to germ-free mice colonized with microbiota from lean donors, even when fed the same diet! This showed that the “obese” microbiome alone could transfer the tendency toward greater fat accumulation and metabolic changes, independent of genetics or calorie intake. The classic experiments (like those by Turnbaugh et al. in 2006 and related work) highlighted how dysbiosis promotes efficient energy extraction from food, fueling weight gain and conditions like insulin resistance. These findings helped establish that obesity can be, in part, a transmissible microbial trait. https://pubmed.ncbi.nlm.nih.gov/17183312/
Personalizing Your Weight Loss Journey:
Human Design Determination
To take your gut health and weight management to the next level, consider incorporating insights from Human Design, which is a system that blends ancient wisdom and modern science to reveal your unique energetic blueprint based on your birth details. In Human Design, Determination (also known as Digestion) refers to your optimal way of processing not just food, but also information and experiences. It’s part of the Primary Health System and guides how you can best nourish your body and mind for peak performance, alignment, and well-being.
There are 12 types of Determination, grouped into categories like Appetite (e.g., Consecutive or Alternating—one thing at a time vs. a variety), Taste (Open or Closed: sampling many foods or sticking to familiar ones), Thirst (Hot or Cold—warm or cool foods/drinks), Touch (Calm or Nervous—peaceful or stimulating environments), Sound (Low or High—quiet or noisy settings), and Light (Direct or Indirect—sunlight or dim lighting while eating). Your specific type, determined by your birth chart, suggests conditions and circumstances as well as sensory capacities that, when attuned to, can enhance digestion and absorption, leading to better differentiation and can improve your stress levels, sensitivity to whats right for your body, and increase metabolic health.
How does this tie into the microbiome? Eating according to your Determination can optimize gut function by reducing stress on your digestive system, which in turn supports microbial diversity and reduces dysbiosis. For example, if you’re a “Low Sound” type, dining in a quiet environment might improve nutrient uptake, fostering SCFA production and GLP-1 signaling. This personalized approach supports digestion, complements microbiome restoration, making weight loss more likely and sustainable. Aligning with your Determination unlocks your body’s natural potential, turning weight management into a harmonious process rather than an uphill battle.

Practical Tips for Gut-Friendly Weight Loss
So, how can you apply this? Sustainable weight management starts with nurturing your microbiome:
-
Boost fiber intake: Eat non-starchy veggies, berries for fruit, and fermented foods like full fat grassfed yogurt or sauerkraut to feed good bacteria and ramp up SCFAs.
-
Consider sporebiotics: Supplements can help restore diversity, especially if your diet lacks variety (but consult a doctor first).
-
Reduce inflammation triggers: Cut back on processed grain products, sugars and seed-oils that promote dysbiosis.
-
Lifestyle tweaks: Nature, movement, stress management, and prioritizing good sleep all support a healthy gut.
-
Personalize with Human Design: Tailor your eating environment and style to your Determination for better digestion and microbiome support.
-
Focus on balance, not extremes: Instead of crash diets, aim for gradual changes that rebuild your microbial community.
So, obesity is often a microbiome-driven issue rooted in dysbiosis, inflammation, and disrupted metabolic signals. By prioritizing gut health and personalizing your approach with tools like Human Design Determination, you can break the cycle, improve insulin sensitivity, curb cravings, and achieve lasting weight loss. It’s not about fighting your weight! It’s about working with your body to let it be the right weight it wants to be. If you’re struggling with energy and weight, supporting your gut microbiota (and living in alignment with your unique design) might be the missing piece.
I’m excited to share some big news with you!
After attending school, it’s common to find a mentor to work under in the functional medicine space. After taking classes with a handful of expert professionals, I enrolled in the KICP Longevity Certification program from the Kalish Institute of Functional Medicine (led by Dr. Dan Kalish, a leading expert in functional medicine who’s trained thousands of functional medicine practitioners worldwide).
This is a comprehensive, year-long certification designed specifically for practitioners like us who want to go deeper into longevity-focused care using lab-based, personalized protocols.
Why this matters to me (and potentially to you)
As someone deeply passionate about Human Design, bioenergetics, and helping people step into their iconic, vital, and resilient selves, I’ve seen how modern life accelerates aging through hidden stressors. Things like mitochondrial dysfunction, oxidative stress, insulin resistance, and muscle catabolism aren’t just “getting older” issues! Unfortunately, they damage DNA, lipids, proteins, and increase our risks for cancer, heart disease, neurodegeneration, metabolic disorders, fatigue, depression, weight gain, and early cognitive and physical decline.
This certification program is helping me practice my lab skills under the eye of a teaching pro, integrating functional medicine with a clear, lab-guided system to reverse these root causes and build truly personalized longevity programs for my clients. It reframes aging not as inevitable decline, but as an opportunity for enhanced vitality, energy, emotional well-being, alertness, and resilience through powerful lifestyle tools like cold/heat therapy, meditation, vigorous exercise, and targeted nutrient protocols.
What the program covers (the four core modules)
-
Toxins & Detoxification — Toxin exposure, liver pathways, oxidative stress, mold, heavy metals, chemicals, and practical ways to reduce toxic burden.
-
Hormone Optimization & Genomics — Lab-based balancing of adrenal, thyroid, and sex hormones, plus genetic factors influencing longevity.
-
Cardiometabolic Health & Mitochondrial Function — Metabolic health, protein misfolding, mitochondrial enzymes, nutrient assessments, gene interactions, and the cell danger response.
