Why your symptoms keep coming back and what your metabolic type reveals about your hormones
You are doing everything right. Eating well, moving your body, getting to bed at a reasonable hour. And yet something is still not working. The fatigue persists. The weight will not budge. The mood dips, the sleep is broken, the bloating keeps returning. You have been told your bloods are normal. You have tried various approaches. Nothing has stuck.
I have worked with so many women in this position. The effort was there. What was missing was an understanding of what was actually driving their symptoms.
Your metabolic type is the answer to that question. I have identified seven distinct types in women, each one reflecting a different hormonal or physiological picture. Each one responds to food, movement and supplementation in a different way. Once you know your type, you stop guessing and start addressing what is actually happening in your body.
Why Your Metabolic Type Matters
Most nutrition plans are built around one assumption: that what matters most is the ratio of calories in versus calories out. But this model is too simple to explain what I see every day in clinic.
Two women can eat the same diet and get completely different results. One loses weight steadily. The other gains it.
Your metabolism is not just about how fast you burn calories. It is a complex system involving hormones, gut function, liver detoxification, blood sugar regulation, stress response and thyroid output. When any part of this system is imbalanced, your body will hold onto weight, produce symptoms, and resist change, regardless of how carefully you eat.
This is why metabolic typing works where generic diets do not. It finds the root cause of your weight gain and addresses it directly.
The Pippa Campbell Method
Before we look at the seven types, it helps to understand the framework they sit within. The Pippa Campbell Method is built on the principle that sustainable weight loss and hormonal balance require addressing the root cause of what is happening in your body, not applying a one-size plan and hoping it works.
At the heart of the method are the Five Foundations, non-negotiable habits that apply to every woman regardless of type. Protein first at every meal, 4 to 5 hours between meals with no snacking, 2 litres of water a day, chewing thoroughly, and eating a wide variety of vegetables daily. These are not optional extras. They are what make the type-specific work effective.
The 7 Metabolic Types
Each type below describes a distinct set of symptoms. Read through them carefully. You may recognise yourself in one type clearly, or you may find you sit across two. That is not unusual, and the quiz will help identify your primary driver.
1. The Digestion Type (DI)
If your gut is central to your symptoms, this may be your type. The Digestion Type is characterised by imbalances in the digestive system that compromise how you absorb and process food. This means that even a healthy diet may not be delivering the nutrition your body needs.
What it can look like:
- Bloating, belching or gas, particularly after meals
- Heartburn or acid reflux
- Food intolerances that seem to be increasing over time
- Constipation, loose stools or fewer than one bowel movement a day
- Anaemia that does not respond to iron supplementation
- Sinus congestion, eczema or asthma
- Brain fog
When digestion is compromised, the downstream effects on hormones and metabolism are significant. This is often where the work needs to begin.
2. The Insulin Type (I)
The Insulin Type is ruled by blood sugar dysregulation. Insulin is a primary fat-storage hormone, and when it is elevated or unstable, weight loss becomes very difficult, regardless of how little you eat.
What it can look like:
- Constant hunger that eating does not resolve
- Fatigue after meals, or persistent tiredness throughout the day
- Cravings for sweet foods or carbohydrates
- Needing something sweet after meals
- A waist measurement equal to or larger than your hip measurement
- Difficulty losing weight despite eating carefully
- Migrating aches and pains
This is increasingly common in perimenopause as oestrogen decline affects insulin sensitivity. It is also frequently missed because standard blood tests may show results within the so-called normal range even when the issue is present.
3. The Cortisol Type (C)
If stress is your primary driver, your weight challenges are likely connected to cortisol dysregulation. Cortisol is your primary stress hormone, and when it is chronically elevated or dysregulated, it drives fat storage particularly around the abdomen, disrupts sleep and depletes energy.
What it can look like:
- Weight gain predominantly around the stomach
- Feeling tired but wired at the same time
- Poor sleep, waking in the night or early hours
- Irritability, a short fuse, or difficulty managing stress
- Shakiness if meals are missed
- Cravings for starchy or sugary foods
- Anxiety
What I see most often in clinic is that women in high-pressure roles, or those carrying significant family responsibility alongside demanding work, present strongly with this type. Managing cortisol dysregulation is not simply about relaxation. It requires targeted nutritional and supplemental support.
4. The Detox Type (DE)
The Detox Type reflects a body where the liver’s detoxification pathways are under strain. When the liver cannot efficiently process and clear hormones, toxins and metabolic waste, the effects show up across the whole system.
What it can look like:
- Unexplained weight gain or an inability to lose weight
- Headaches or migraines
- Night sweats
- Skin problems including rashes, itchy skin, dermatitis or psoriasis
- Brain fog, poor memory or cognitive sluggishness
- Low mood, irritability or anxiety
- Bloating or constipation
- Sensitivity to smells, additives or processed foods
Supporting liver detoxification pathways is essential for this type, and it is not about juice cleanses. It is about specific nutrients that support phase one and phase two liver detox processes.
5. The Thyroid Type (T)
The Thyroid Type indicates low thyroid function, which directly affects the speed of your metabolism. This is one of the most commonly missed types because standard GP testing often fails to capture the full picture.
What it can look like:
- Persistent fatigue or feeling sluggish
- Feeling cold, particularly in the hands and feet
- Needing excessive sleep to function
- Weight gain despite dieting, or an inability to lose weight
- Constipation
- Low mood and lack of motivation
- Hair thinning or excessive hair loss
- Loss of the outer third of the eyebrow
- Morning headaches
In my experience, many women living with these symptoms have been told their thyroid is fine. But standard TSH testing alone does not always reveal what is happening functionally. This is why comprehensive testing matters.
6. The Oestrogen Type (O)
The Oestrogen Type is driven by oestrogen dominance, which means oestrogen is elevated relative to progesterone, or the body is not clearing used oestrogen effectively through the liver. This is particularly common in perimenopause.
What it can look like:
- PMS or PMDD
- Heavy or irregular periods
- Irritability, mood swings or rage
- Anxiety or panic attacks
- Bloating and poor digestion
- Insomnia or restless sleep
- Breast tenderness or fibrocystic lumps
- Endometriosis, fibroids or ovarian cysts
- Headaches around ovulation or in the days before your period
Addressing this type requires supporting the body’s oestrogen clearance pathways as well as reducing the drivers of excess oestrogen production. This is not a straightforward type to address, but it is a very treatable one.
7. The Serotonin Type (S)
The Serotonin Type is associated with low levels of serotonin, your mood-regulating and appetite-suppressing neurotransmitter. This is not simply about mood. Serotonin has a direct relationship with food choices, cravings and appetite regulation.
What it can look like:
- Low mood or depression
- Feeling flat, or lacking joy from activities you used to enjoy
- Feelings of inner anger or rage
- Carbohydrate cravings, especially in the evenings
- Increased appetite
- Poor sleep or an inability to reach deep, restful sleep
- Sensitivity to pain
- SAD (seasonal affective disorder), feeling low in winter
Serotonin is largely produced in the gut, which means this type often overlaps with the Digestion Type. Supporting serotonin precursors through nutrition and targeted supplementation can have a significant effect on both mood and appetite.
Why the Quiz Changes Everything
Reading through the seven types, you may have recognised yourself in more than one. This is common. Most women have a primary type and one or two secondary types running alongside it.
The Metabolic Type Quiz is designed to identify your primary type accurately, based on your specific symptom profile. Once you have your result, you will receive a detailed breakdown of what your type means clinically, what your hormones and metabolism need, and which targeted supplements and next steps are most relevant to you.
The follow-up content is personalised to your type. That is what makes it useful rather than generic.
What I see in clinic, time and again, is this: when a woman stops following a plan designed for someone else and starts addressing what is actually driving her symptoms, everything becomes easier. Energy improves. Sleep deepens. Mood stabilises. Weight follows.
The quiz is where that process begins.
