I feel so much happier when I keep things simple.
I participated in a nutrition and training program that had me counting calories and doing hour-long multi-exercises and multi-set workouts. This plan would have brought good results, but the time associated with entering all these details and devoting 60-90 minutes each day is unnecessary.
As you may know, I've been seriously weight training since I was about 13 years old. I'm now 57. That's almost 45 years of experimenting and taking notes on how my body responds to training and nutrition. I am always open to testing and encourage you to do the same. Try something and see how your body responds. Do you have more energy? Do you sleep better? Are your mood or stress levels better?
Record what you do, and refine. Do what works for you.
Here's an example of a simple breakfast. I throw everything together and check off many nutritional boxes in one swoop.
This morning's morning oatmeal consisted of organic, thick-cut oatmeal, frozen organic cherries, grass-fed whey protein powder, pecans, and a little shredded coconut.
