Why “Eat only when you’re hungry” won’t work

During a recent social event, the conversation turned to weight loss and dieting. One of the women said she read a new book and it had “the answer” to her problem of weight gain: eat only when you’re hungry.  Many books and weight loss plans, in fact, emphasize this point, offering various tips and methods to define “hungry” and help the reader learn what kind of hunger, exactly, they should satisfy and what kinds they should ignore.  The worst books (in my opinion) give the message that people gain weight because of various psychological or “spiritual” hungers that we try to assuage with food.  There is little to no consistent science to back up these claims, and I believe the message does much harm, because it implies an almost magical answer to the problem  of overeating.  When it inevitably fails to work, the victim of this propaganda is left with yet another cycle of failed dieting and increased weight.

As recently as hundreds of years ago, most people did need hunger as a cue to begin eating, because their days were full of physical labor and food was not always readily available.  But, in recent decades, this situation has changed dramatically.  Now, most have relatively low levels of physical activity and the availability of food has increased exponentially — to the point where there is a glut of high calorie, low cost “food” in our faces continually.  We rarely get hungry in the old sense of the word, because these cleverly marketed and subsidized foods (high in sugar, salt and/or fat) overwhelm our biological regulatory systems.  Instead, we develop cravings and hungers triggered by environmental cues and implanted “beliefs” from our culture, no longer based on biological requirements.  In a sense, we get “addicted” to unhealthy foods and lose our ability to trust our hunger.

So, what can we do?  Easy — and difficult.  Train ourselves to ignore these contrived temptations; limit our exposure to them (most importantly, protect our children from them!).  Learn what a healthy lifestyle looks like and adopt it.  Avoid frequently eating “addictive” foods containing large amounts of  sugar, salt and fat.  And advocate, loudly and often, for changes in our culture so that fruits, vegetables and other unprocessed foods are cheaper and more available than the junk food that now receives so many economic advantages.

P.S.  I have not posted in the last 3 months for several reasons, one of which is having surgery and recovering.  I’m fine now, though.

  1. Personal Trainer Says:

    I read somewhere that we should eat 6-7 times in a day i.e. at frequent intervals in less amount. We should eat when we feel hungry. People who are very conscious about their health do dieting but that’s not good. We should eat healthy and nutritious food at many time in a day. It keeps us healthy and fit.

    Check out the book (I Can Make You Thin) by Paul McKennma and (Eat What You Love and Love What You Eat) by Michelle May M.D. We need to truely learn when we are hungry and stop feeding our emotional hunger, as in sad, happy, bored, scared anxiety, physcial pain, depression and so forth. It is not easy, it is real work. Also Michelle May has about 7 youto clips that gives highlights of the real world self talk and eating.

    I used to eat 3 times a day but now I only eat when I am hungry, it feels much better. I do not really care about what is recommended, I rather listen to my body to tell me what it needs. I guess people have lost touch with their own body and prefer rely on outsiders info…I no longer do that, as I feel that it didnt work for me.
