why you must embrace the right fats for weight loss
For decades, we’ve been told that fat is the enemy. The story goes back to the 1950s, when researcher Ancel Keys claimed that saturated fat was the main cause of heart disease. His work influenced government guidelines, food companies, and public opinion. But later investigations revealed that Keys had manipulated data to fit his theory. Unfortunately, the myth that “eating fat makes you fat” still persists today.
The truth is quite the opposite: eating the right fats is one of the most effective ways to lose weight and stay healthy. Think of your body like a high-performance car. A sports car won’t perform well on cheap, low-octane fuel—it needs high-octane fuel that packs more energy per gallon. In the same way, your body and brain thrive on high-quality fats, which provide clean, lasting energy.
Fats aren’t just fuel; they’re fundamental to life. Every cell membrane in your body contains fat. Your brain is largely made of fat. Even your nerves rely on fat. The protective coating called myelin, which surrounds nerves, is built from fat and allows signals to travel faster. The better your myelin, the more quickly your brain and body can communicate. Consuming healthy fats helps your body burn energy efficiently, build stronger cells, and even think more clearly.
So which fats should you choose? Nutritionist Mary Enig outlined two ways to judge them. First, by the length of the fat molecule: shorter and medium-length fats, like those found in MCT oil, are rare and anti-inflammatory, making them excellent for energy and weight loss. Second, by their stability: saturated fats are more stable, meaning they oxidize less easily. Since oxidation drives inflammation and aging, stable fats protect your body rather than harm it.
That’s why the Bulletproof Diet, a high-fat, low-carbohydrate eating plan created by Dave Asprey, recommends fats like MCT oil, ghee, cocoa butter, krill oil, avocado oil, coconut oil, sunflower lecithin, and grass-fed butter. These fats fuel your body without the crashes and inflammation that come from excess carbs and unstable oils.
If you want to lose weight, don’t fear fat—embrace the right kinds. Your body is designed to run on it, and when you fuel it properly, you unlock sharper thinking, better energy, and sustainable health.
