Some further thoughts - Like you I also like to cook. I don't really use written recipes - I combine ingredients as needed depending on what is available and how strong / weak things are. After working with an ingredient for a while, you get an idea of how it works so you don't really have to measure every time.
I use CalorieKing.com to get an idea of the calorie density of groups of foods: oils, grains, nuts, beans/legumes/, vegetables and then estimate how many calories and how much protein is in a dish I am making. It is really easy to do - I do it in my head. All you need is a rough idea. If you are checking your weight, your scale will tell you when you have a problem. Then you can dig in deeper.
I estimate per dish - never write it down - just keep in my head for reference. For example: olive oil (a favorite of mine) has 120 calories per tablespoon. Two to four tablespoons is plenty for an entire pan of stir-fried vegetables and tofu. The vegetables range for 4 to 9 calories per ounce -- basically nothing. The tofu I use has about 480 calories in an entire pound with about 45 grams of protein. I just add up how much I put in and have some idea of what I am eating. Add in some cashews which have some calories - about 100 in a small handful. Soy sauce or miso has nothing. So there may be 1300 or 1400 calories in a large pan of stir fry that might take me three or four meals to eat - about 400 calories per sitting. I spread it out over a few days...
Like I said, I eat other stuff too. So I am eating about 2000 calories per day to maintain my weight at 190 lbs. I am a 6' 2" male who is 47 years old. I used to weigh 400 lbs and consume over 5,000 calories per day to maintain that weight. It was all processed and fast food. What a change!
The scale is my check - if I am gaining weight (or losing it), I can start logging everything to see where the problem lies. Logging in detail every calorie consumed really take the fun out of everything. I only do it if I have to.
The salt, fat and sugar that occurs naturally in the foods I am eating is in-balance with everything else, so there really is no need to track it on a daily basis. I don't eat low-sugar, low-salt or low-fat processed foods as salt, sugar and fat add flavor and feel to food and are necessary components of a healthy diet.
Of course I take the recommended supplements and get regular labs - that combined with my weight keeps my on-track.
