"Take care of your body. It's the only place you have to live." — Jim Rohn (Jim Rohn was an American entrepreneur and author whose work on personal development influenced a generation of writers and coaches, including Tony Robbins. He died in 2009.) I've read two key books on nutrition: The Magic Pill by Johann Hari and Ultra-Processed People by Dr Chris van Tulleken. Both are must-reads, and both say a similar thing: the obesity epidemic we're experiencing in the west is due to processed food in our diets. There's significant scientific evidence that exercise does little compared to a healthy diet for losing weight. This hit home for me, so I decided to try it. For a month I ate only steak and eggs, and the weight flew off me. The more I investigated it, it wasn't due to the carnivore diet, it was due to the lack of processed food. I want to be clear: I don't recommend the carnivore diet. Carbohydrates are the body's primary fuel source and cutting them out entirely isn't sustainable or necessary. What made the difference was removing processed food, not removing carbs. This changed my outlook completely. Now I aim for 80% of my diet to be made up of one-ingredient foods. There are days when you must have that Indian takeaway, or the alluring smell of Gregg's steak bake draws you into a shop, but overall, aim for 80% single ingredients: meat, fish, butter, cream, cheese, eggs, vegetables, and fruit. Don't be drawn in by the myth that fats are unhealthy. The corporate demonisation of fat is one of the most successful marketing campaigns in modern history. When flawed research in the 1970s suggested saturated fat caused heart disease, the food industry didn't just capitalise on the fear, they amplified it. Cereal giants like Kellogg's led the charge to reframe breakfast from eggs and bacon to bowls of processed grains. They funded studies that conveniently favoured their high-carb products whilst positioning themselves as the healthy alternative. These companies poured millions into marketing campaigns that painted fat as the dietary villain, plastering "heart-healthy" and "low-fat" across packets of sugar-laden flakes and loops. The result? A multi-billion-pound industry built on convincing generations that processed corn with added vitamins was somehow healthier than the eggs humans had eaten for millennia.
