Sam Feltham's 5000 Calorie A Day Diet

Health activist, a friend of The Training Room, and founder of Smash the Fat Fitness & Fat Loss Bootcamps, Sam Feltham, shares some of the findings from his ‘21 day 5,000 calorie self-experiments.
“For my first 5,000-calorie self-experiment, I ate a low-carb high-fat diet of real foods. Mainly eggs, fish, steak and nuts with green vegetables. During that experiment, I ended up gaining 1.3kg in weight but lost 3cm from my waist circumference. From that, you might think “Sure, you're a naturally slim guy and probably very active” and you'd be right. However, with my second 5,000-calorie self-experiment, I ate exactly the same amount of calories and exercised exactly the same amount over the 21 days, but this time ate a high-carb low-fat diet of ‘fake foods’ such as cereal, bread, pasta and 0% fat yoghurt. During this experiment, I ended up gaining 7.1kg in weight and 9.25cm on my waist circumference. Quite a substantial difference between the two experiments despite the same amount of calories eaten and exercised.
“The reason there was such a difference between the two diets is because of the different biochemical reactions to the different foods in my body, and this is what the past 15 years of nutrition research have shown in over 20 randomised controlled trials. To quote cardiologist and one of our scientific ambassadors, Dr Aseem Malhotra: “We've been told for years that eating fat will make you fat because it contains twice the calories that are in carbohydrates. That is to misunderstand how fat storage works.” The reason that we gain or lose body fat is entirely down to our body's biochemical reactions to the foods that we eat, not the total amount of calories that we consume. This isn't a license to gorge on as much steak as you can – 100 calories of steak will have a smaller biochemical effect than 1,000 calories – but what it does mean is that when it comes to fat loss, biochemistry leads and physics follows.”

saying about us
I’ve just completed my course via the E-learning academy and I want to thank Nick Hewett, my tutor for his exceptional guidance and support. He always responded to my emails and marked my work submissions very promptly, giving really helpful feedback. Couldn’t have asked any more of him.

I just completed my L3 PT Diploma as an e-learning course. It was the perfect option to be able to self-pace my study and coursework as I couldn’t commit to a purely weekday or weekend course, and could do my work when it suited me. The training room provides ample resources for self-study, and a tutor who is always there to help. Hasit Jethwa, my tutor, was excellent at answering any of my questions quickly and was really clear and useful in letting me know what I needed to do! Having Hasit as my tutor really added to my experience of qualifying with The Training Room. Thank you!

I’ve just received a Pass for my theory exams, so thought a review would be a good commemoration!
I took the Hybrid Course; a weekly live lecture on Zoom, coursework on Google Classroom. My tutor Hasit Jethwa is a Physio and amongst other accomplishments. He is highly knowledgeable, a self - confessed nutrition nerd, eloquent, and a pleasure to interact with. I really enjoyed my course, and have taken away so much to carry on learning.
It’s a flexible course style which fitted around my lifestyle and other commitments well. L4 Nutrition here I come.

My tutor Liz Shaw has been an absolute diamond! Her support and encouragement throughout the course has made my experience at the training room better than could have imagined. Defo lucked out with her as my tutor. Her knowledge and background in personal training and dance is strong and her teaching style is solid! Thank you Liz and big thanks to the training room!

I've just completed the L3 Diploma in Personal Training with the Training Room and would highly recommend it. I took the hybrid option which meant I could fit the work in around working full time.
The tutors were really knowledgeable and supportive throughout the course, and I wanted to give a special shout out to Mark Fox who was just amazing. Mark really knows his stuff and gave us so much help and support in the online lectures, but also any time I reached out to him. He was really quick to respond, and although I'd finished the teaching part of the course I still felt I had support whenever I needed it.
This qualification really is going to change my life and I can't wait to get going. Thanks again to the Training Room and Mark.
