First thing to remember about me: I am lazy with regard to processing "details." Calories are the worst sort of detail there are in my book.
Second thing to remember about me: I use simple rules of thumb translated into behaviors that are easy for me to perform on an on-going basis with regard to maintaining my level of fitness.
Third thing to remember about me: I live and train instincitvely. I have very specific plans for the short range, mid-range, and long-range aspects of my life, but my daily methods of traversing reality are executed with a rough bullet point outline, and the rest figured out on the fly, as too much planning too soon often results in wasted effort when reality reminds you that your plans are not in charge of the universe.
So, with that in mind, I offer the following:
Finding and Maintaining Equilibrium:
(1) Determine what your equilibrium is (e.g. ration of mass to definition), and do whatever you need to in order to get there. This is most likely an assumption, but I am listing it just for the sake of being thorough.
(2) Choose some other means of evaluating your physique other than a scale. For instance, I go by how my clothes fit, and how I look in the mirror, way more than I do by my actual bodyweight.
(3) Eat 5-6 small-medium meals per day.
(4) Never eat a serving of carbohydrates bigger than your fist in one sitting.
(5) With regard to the size of your meals, consider the following: "Eat the breakfast of a king, the lunch of a prince, and the dinner of a pauper." OR, more simply put, Eat larger portions earlier on in the day as you have the rest of the day to burn them off, and decrease your serving sizes as the day passes by. EXAMPLE: I start cutting my carbohydrate consumption at 12:00 PM. I only eat protein and vegetables for dinner.
(6) Limit your sodium intake, and your intake of alcohol. Both bloat you.
(7) French fries or other favorite sin food only once per week at most.
(8) Eat cheese at most once per day. Cottage cheese does not count, as it is all protein and no fat, if you get the light stuff.
(9) Examples of mini-meals include: nuts + banana; protein shake; scrambled eggs + fresh fruit; turkey sandwich, etc.
(10) Drink lots of water. It helps keep you full, and it helps to burn fat.
(11) To make yourself feel full if you are hungry and have been getting proper nutrition, try the following: Eat 1 apple, then drink a glass of water. The water will make the fiber in the apple expand in your stomach and take longer to digest, making you feel full.
(12) Keep up your cardio, and if you can, do your workouts in the morning, as you will spike your metabolism at its lowest point (waking up) and benefit from a slightly increased metabolism the rest of the day due to the early AM kick start.
(13) Be smart about mayonnaise, sodas, sour cream, etc. Don't let condiments blow your nutritional profile.
(14) Eat whole foods, stay away from stuff in cans, boxes, jars, etc. Eat what cavemen ate!
