What you stop eating has a bigger impact on your health than what you start eating. So you can start eating a lot more broccoli or a lot more of whatever you think is good for you, but if you don't stop eating that pizza, there's no amount of broccoli you're gonna eat that's going to take care of all the damage you're doing from eating something that just doesn't work for you. As Dave Asprey says, the fastest way to boost your performance is to quit doing the things that are draining your energy. Whether that's your health and vitality or your psychological health and vitality or your relationship. Stop doing the things that are damaging your relationships or your mind or your body with what you're eating. You will never find a fountain of youth. You won't find one thing that you could eat or do that will keep you alive forever. You won't find that, it doesn't exist. But there are things in that forest that you can eat that will immediately kill you. Poisons exist, Fountains of Youth do not. We want to stop doing the things that are toxic for us if we want to optimize our well-being.
