Nutrition and lifestyle are the keys to longevity
A blog by Michael Butler
Articles and opinions for my family & friends about how I am living a healthier life informed by scientific research undertaken since being diagnosed with heart disease. Starting with the principle that each of us is biologically unique, everyone can use nutrition and lifestyle to achieve their greatest potential.

Are you worried about cholesterol?
If the answer is yes, you are worried about cholesterol, take a look at this article. I’ve done a deep dive into the literature and provide here an update. I don’t think cholesterol could have caused my heart disease because it is essential for life, my body makes most of the cholesterol I contain, and study after study in the literature demonstrates that not only is it unlikely to be harmful, too little is, in fact, associated with poorer health.
The six signs that you may have a food addiction
Food addiction is real and it’s no joke - it should be taken as seriously as smoking, drinking too much and drug addiction. Dr. Jen Unwin is a UK expert on the subject and recently shared her thoughts in a British Sunday newspaper
Nutrient-Dense Low Carbohydrate Diets Outperform GLP-1 Drugs for Weight Loss
This is another welcome example of mainstream media spotlighting the benefits of real food over pharmaceutical fixes. With some effort, a low-carbohydrate, nutrient-dense diet can match or even exceed the effects of popular weight-loss drugs—without the cost, side effects, or muscle loss.
2025 Mid-year review
As it says on the tin…a quick recap of my 2025 objectives and description of what I’ve done. I’m really benefitting from reader feedback this year. Please keep your thoughts and ideas coming.
It’s the starch that gets us – it’s simply sugar holding hands
If you’ve cut sugar from your diet and are still struggling with your weight, there’s a good chance starchy food is the issue. Starchy foods are rapidly converted to sugar. Our highly efficient digestive system breaks down bread, rice, pasta, and potatoes into glucose almost immediately, leading to unhealthy high blood sugar and insulin.
Nature - Summer Solstice 2025
The summer solstice is a time during which plants have been shown to synchronise their reproductive activity.
The Extinction of Experience
What happens when an entire generation loses perspective? “We accept the unacceptable because it is normal.”
The modern human diet, full of seed oils and industrially processed carbohydrates, is unnatural, is damaging our metabolism, and leading to obesity, heart disease, type 2 diabetes, and more. My generation has come to believe that the solution is a pill. For many of us, the real answer may be much simpler: eat real food.
April/May Seasonal Update: The Rapid Increase in Sunlight
Spring in the north is a time of a rapid increases in daylight hours and temperature. These drive equally rapid growth in biological activity in the world around us and in our own bodies. If we connect with the natural world at this time of year we can literally feel the increased energy. This article describes how I do that.
Food Addiction: my experience, the evidence, and a path forward”
Our biology can be easily hijacked by modern, processed foods and my recent experience caused me to reconsider the concept of food addiction. High-carbohydrate and ultra-processed foods can trigger addictive-like responses in the brain, leading to cravings, overeating, and poor metabolic health. Cutting back on these foods and focusing on real, unprocessed food can help reduce food addiction symptoms, improve mental well-being, and support sustainable weight management. I consider how to do this.
High-Carb Experiment: Bikepacking, Performance, and Lessons Learned
I’ve recently learned that higher than normal carbohydrate intake improved my physical performance and recovery during a two-day bikepacking event compared to previous under-fueled attempts. However, my improved endurance came with digestive discomfort and post-event food cravings. My experience highlights the balance between fueling for performance and maintaining metabolic flexibility…both matters of a personalised nutrition strategy.
I need more dietary carbohydrates for strenuous exercise
Strenuous exercise needs carbohydrate fueling, especially if you consume a healthy, low carbohydrate diet. This is how I’m trying to reach my exercise potential…
March Seasonal Update: The Return of Full Sunlight and a Waking Garden
Here comes the sun…get a suntan…safely
The Hidden Dangers of Modern Food: Understanding and Overcoming the High-Carbohydrate Trap
If you’re struggling with your weight the culprit may be modern food. It is chock-full of hidden sugars and starches which are addictive and cause all sorts of health issues. I broke free from the cycle of cravings and poor health by reducing bioavailable carbohydrates, eliminating processed foods, and focusing on nutrient-dense whole foods. In my opinion, these things hold the key to long-term wellness.
Nature - Spring equinox 2025
The days are getting longer and warmer. I’ll have to find something new to complain about.
Scotland started basking in sunlight today
Scotland isn’t the first country that comes to mind when considering where to get an early Spring sun tan (and neither should it). However, today on March 11, for the first time in 2025, the sun has started giving us some UVB and potential to generate Vitamin D in our skin. It only lasts for about 30 minutes but as my boss used to say, “It’s time to dine on the delta”. Let the tanning and vitamin D production begin.
Carnivore diet replaced drugs for ADHD and Depression
This is the inspirational story of one young man finding the strength to figure out for himself how to use his diet to reverse poor mental health.
Local and seasonal - February 2025
If, like me, you believe that exposure to the natural world is important for a healthy life, how can that be achieved? I believe we are adapted to consume real, local food, regularly replenish our microbiome, feel the sun’s warmth, and benefit from touching the earth. This article is the first in a monthly series describing how I do that…even in chilly February.
What’s in store for 2025?
I’ve never been good at predicting things, especially the future. We’ll see if this plan survives exposure to the field of battle. Two big things…we need to take care of ourselves…this means being exposed to the natural world we evolved alongside. Think real food, the microbiome, sunlight, and the earth’s electrical charge.
The UK diet lacks vitamins and minerals
People in the UK get on average 50% of their dietary energy from ultra-processed food (UPF). It is shown in this paper that UPF does not contain enough vitamins and minerals to provide the minimum amounts recommended by UK dietary guidelines. A dramatic rise in hospitalisations caused by vitamin and mineral deficiencies has been recorded.
A lack of vitamins and minerals from food increases NHS hospital admissions
A simple headline in the Guardian newspaper caught my attention immediately. Adequate Vitamin and mineral levels are a core determinant of a healthy life. When people are showing up in hospital because of or with a lack of vitamins and minerals, something has gone seriously wrong. I dug into the numbers and present here what I think may be going on and how to fix it.
