I really need to lose weight, my heaviness has started to lead to other health problems, but I find that whenever I try to eat significantly less, I have difficulty concentrating on heavy mental tasks (i.e. programming, my job). The constant feeling of hunger distracts me, or my mind just drifts, until I get some food in me again. I never see any of these articles even acknowledge this as an issue, either as if no on…
You will usually find that eating slower will satiate you with less food and over time you'll start eating less.
That being said, I have not experienced the same symptoms as a result of hunger - I find the feeling a minor annoyance at best, certainly much lower than other environmental factors that usually impede concentration (temperature, noise, lighting).
Certainly the individual responses to feeling of hunger vary from person to person.
