Hearing the term ‘metabolic dysregulation’ might leave you scratching your head in confusion. What’s that and what does it have to do with me? I can hear you say.
Do any of the following sound or feel familiar?
If our metabolism is struggling due to the nutrition it is receiving or our lifestyle factors, it can set off a chain-reaction of health issues, starting with the seemingly innocuous muffin top, through to high cholesterol, a creeping blood pressure and blood sugar imbalances.
Most people relate metabolism to weight loss or gain. I’ve often heard clients say that they have a ‘slow metabolism’ because they are finding weight loss slower than they hoped, but it is more intricate than that. Metabolism is literally at the source of every process in our body. Our metabolism isn’t a single thing, it is a myriad of process that breaks down nutrients from food and turns them into energy and components which help support all of the body’s cells, organs and systems.
It is, therefore, a lot more than an issue of weight gain and weight loss. Although being at a healthy weight is a key part of maintaining a healthy metabolism.
BMI (Body Mass Index)
What is a healthy weight? Well, that depends on a number of factors. Your height and weight for a start, how athletic and muscular you are and what life stage you are at. You’ve probably heard of BMI – body mass index – which most health professionals use as a basis for measuring a healthy weight parameter. The formula for calculating BMI (metric) is BMI= Kg/M2 but there are dozens of BMI calculators available on the net or in the app store which allow you to check it easily.
A normal BMI is considered to be between 18.5 and 24.9.
Overweight is between 25 and 29.9.
Obesity is classed if a BMI is over 30.
Please note, however, that if you are very sporty and muscular you might have a high BMI whilst actually being very metabolically healthy, so it is always worth checking with a health or nutrition practitioner before making any changes to your eating and lifestyle habits.
Body Composition Analysis
There’s a lot more to metabolic health than just your BMI or waist to hip ratio. A body composition analysis which can be done with a nutrition practitioner, at the gym or even at home with some basic body composition scales, although beware of the accuracy!
A body composition breakdown gives you additional information including fat versus muscle mass, where the fat is in the body, how much visceral fat you have (visceral fat is the fat that is located near your organs and that can cause the most damage, health wise), water percentage and bone mass. All of this information can provide a much clearer overview of your health.
How can diet and lifestyle help?
If you go back to the notion that your metabolism, which is at the basis of all of the processes in your body, is dependent on the food you eat, then it becomes clear how your nutrition can have an impact on your metabolism and health. Lifestyle factors such as sedentarism (sitting too much) and poor sleep have also been shown to have long lasting impacts on a person’s metabolism, we will cover this in a later blog.
It is important to remember, however, that there is no one-size-fits-all solution. The reason that there are so many different diet clans out there proclaiming that their way of eating is the solution to all, is because all of those ways of eating do suit some people, just not absolutely everyone.
I trained in Nutritional Therapy exactly because I don’t believe that we can all follow the same thing and get the same results. Over and over again in clinical practice this fact is confirmed. Each person needs to find the best way to nourish themselves that suits them best metabolically and which is sustainable for them long term.
Foods to Minimise
The science is stacking up against foods that are produced from ingredients extracted or refined from whole foods or Ultra-Processed Foods and Drinks (UPFD). These types of foods and drinks are all around us. Baked goods such as biscuits and cakes make up the largest group in the UPFD category and we all know how easy it is to reach for a chocolate hobnob with our cup of tea.
Fizzy drinks account for the lion share of the UPFD drinks market, how often do you add a can of something to your meal deal?
Lots of studies have been published over the last decade showing again and again the link between regular consumption of UPFDs and poor health outcomes. These range from cancer to cardiovascular disease, respiratory disease and diabetes.

Even before the global pandemic that is putting such a strain on everyone's mental health, depression and anxiety were the most common mental health conditions worldwide and that's not even counting those people who suffer from low moods and anxiety, but who don't consult a doctor about it.
Food and drink today, particularly of the ultra-processed variety, has been positioned as a reward by the food industry and this has led to people turning to what they perceive as 'comfort foods' when they are feeling down, or are stressed. The trouble is, with modern society the way it is, humans now spend more time feeling down and stressed than ever before. COVID-19 is simply magnifying this already existing sense of malaise.
Over the past decade, the research community has taken more interest in the link between what we eat and how we feel. The comfort foods that people tend to turn to are high in carbohydrate and sugars which have an immediate effect on our blood sugar levels, sending them soaring. The trouble is, what goes up, must come down and the subsequent significant drop in blood sugar levels, result in another mood and energy crash, which leads to another attempt to raise levels by eating more carbohydrate/sugar rich foods. The mood rollercoaster.
Did you know that diets high in refined carbohydrates and sugar are also inflammatory? Long term or chronic inflammation has been found to link back to a higher risk of depression and this might link to potential damage to our microbiome..
Our microbiome - or bacteria population in our large intestine - has a direct liaison with our brain and vice versa. If our microbiome is out of sorts and less varied, then this has been shown to also impact on mood and depression risk. Gut permeability or 'leaky gut' which is basically a gut lining that is allowing particles through into the blood stream that should have remained in the intestine and evacuated, is also linked to depression, probably via the decreased availability of Serotonin.
Serotonin acts as a neutrotransmitter, basically a messenger that relays message from one part of the body to the other. Serotonin acts in the brain, but also on the cardiovascular (heart), muscular and endocrine (hormones) systems. Serotonin has become well-known through its inclusion in anti-depressant medications that are based on Selective Serotonin Reuptake Inhibitors, despite the fact that scientists still don't know what role serotonin actually has within the brain and why lower levels of serotonin lead to depression. The only thing we do know, that in certain people using SSRIs to increase the amount of serotonin within the brain does have an effect on mood.
One thing is known, however, only 10% of serotonin is found in the brain. The remaining 90% is found in the gut. To have good functioning serotonin levels, therefore, it is key to ensure that your gut health is tip top.
