Unlocking Health: The Science of Added Sugar and Its Impact on Health & Fitness



I wanted to come back to another blog about added (refined) sugar. I have been understanding more and more about the negative consequences of added sugar intake and at the same time, feeling kind of angry how corporation, in their greed for money, have the unchecked power to fuel what is a health crisis. It's no secret that added sugar triggers a rewards response in our brains, making us feel good by releasing serotonin which leads to addictive eating patterns and business is exploiting this. I want to fight back and I want you to join me to cut out added sugar and reduce the toxicity to your body.


The Sugar Situation in the UK is as bad, if not worse than in most other parts of the world. On average, a person in the U.K. consumes approximately 93 grams of added sugar per day, which is nearly three times the recommended daily limit (a recommended daily limit which is already, in my opinion too high and outdated). Excessive sugar intake has been correlated with various health issues - including depression, obesity, diabetes, heart disease, cancer and linked to mental health and energy issues. Sugar stops our immune system from working effectively leading us down to a whole pile of increased health risks. Added sugar is absolutely not necessary in our diet.


- A 2019 study published in the British Journal of Nutrition found that individuals who reduced their sugar intake experienced a significant decrease in body weight and improvements in metabolic health.

- Research in the Journal of the American Medical Association (JAMA) showed that a low-sugar diet is associated with a reduced risk of developing type 2 diabetes.

- Increased Energy Levels: Sugar reduction maintains stable blood sugar levels, providing consistent energy throughout the day and reducing energy crashes.

- Enhanced Mental Clarity: Scientific studies indicate that a sugar-conscious diet can improve cognitive function and reduce the risk of cognitive decline.

- Improved Skin Health: Sugar has been linked to skin issues. Sugar reduction can lead to clearer, more radiant skin, positively affecting overall appearance.

- Reduced Risk of Chronic Diseases: Studies show that lower sugar intake significantly decreases the risk of developing conditions such as diabetes, heart disease, and certain cancers.


As a personal trainer, my journey of reducing sugar intake has had a profound impact on my life. I've witnessed substantial improvements in my health and fitness, making me a better role model for my clients. I have experienced higher energy levels, clearer skin, and a better physical condition in relation to body composition. By removing calories from sugar from my diet, at the same time i've been able to replace this with much healthier foods. Naturally, my diet becomes much healthier as sugar laden foods comes with other nasties including preservatives, salts and trans fat - too big a subject to discuss here and maybe I don't yet know enough myself.


By embracing a sugar-conscious lifestyle, you can experience similar positive changes. Picture having the energy to conquer your workouts, the mental clarity to make healthier choices, and the confidence that accompanies a healthier, more vibrant you, with fewer health worries and conditions! It's about feeling fantastic and enjoying a longer, healthier life, while sticking a finger up to corporations who have no interest in our health and well-being.


Reducing sugar intake is not a fleeting trend; it's a science-backed choice for your health and fitness journey.


If you're ready to make a meaningful change, join me on this sugar-conscious adventure. Together, we can unlock your full potential. Your body, mind, and future self will thank you for it!
