The hard way is to follow a Standard American Diet (SAD) - rich in animal protein, cholesterol, refined oil, and sugar - for many years. At some point, this way of eating will invariably cause a horrible chronic disease (heart disease, cancer, diabetes, autoimmune disorders, endocrine dysfunction, arthritis, obesity, etc.) and quality of life will drop precipitously, followed by a long and miserably slow death.
The easy way is to eat a whole food plant based diet 95-100% of the time and feel great every day, while living a healthy life well into old age, then dying peacefully in your sleep.
The problem, of course, is if you choose the hard way, there's no coming back from that. Once chronic illnesses set in, they are hard or impossible to reverse (with the exception of heart disease and Type 2 diabetes). Then you can only regret not having heeded this blog post and the advice of health professionals, when you had the chance.
All else held constant and assuming everyone has about the same likelihood of being creamed by a bus, whole food plant based eating is the way to go.
This blog post is intended to guide you gently toward the easy way. But if you feel like you need to do it the hard way, good luck to you, because you will need it.
The End.
