That probably doesn't work either unless they work in an automated fashion. Did the chef put two or three dashes (official SI unit) of this or that on your meal? A a "dash" or "splash" or "spritz" of certain things can easily mean 100-200 kcal. And if you deal with things like meat, maybe the cut you get today is more or less lean than what you got last week.

I think tracking calories for a couple of weeks can be very enlightening for a lot of people, granted you don't have a personality type where this can get you into trouble. But for the long haul it's not really useful or even feasible, you're better off getting to know what sort of way of eating suits you best and how to correct if you're getting off course. Anyone can stick to a very strict regime for three months, but the trick is to stick to a proper diet you can enjoy for three decades and then three decades more.

Healthy foods are not healthy in an excessive quantity. Diets don't need to be tracked to the individual calorie. We don't burn the same amount l number of calories each day and food labels show an average of the nutritional value. If a person is consistent, they will achieve the desired result; either gaining or losing weight.

I've been tracking consistently for about 5 years. It's feasible.

It works medium term for lots of people. Helped me get visible abs. But I do agree that tracking calories for the rest of my life sounds exhausting.
