Think of a trader who starts trading today. What would you tell him? You would tell him to prepare to spend the better part of the next 5 years going through various cycles both up and down. Improvement in trading and in health happen very slowly over time even though we all want to get rich now and get fit now! The problem with rapid weight loss or even rapid muscle gain is it throws your body out of whack. It's not natural and it won't last because your body has a tendency to fight any rapid change in your body whether it's good or bad. The guys who are in the best shape, the guys that make it look easy, took years and years to get fit. They focused on very minimal gains. This allowed their body to slowly transform without the evolutionary restraints that will try to hold you back. This is why many talk about a lifestyle change vs. the concept of a "diet". A diet is something that has a beginning and an end. A lifestyle is permanent. A lifestyle will allow for the slow gradual change that will be the new "permanent" you. Not the temporary you that is the result of some radical routine to force a result to happen quickly. If you eat well and exercise well over time your body will change slowly. Watching the scale every day is like a new trader that watches every up tick and down tick in their p&l. It's a waste of time.
