Overweight and obese people who manage to lose weight and then regain it – yo-yo
dieters – have a problem, yet it’s not in their stomach but in their
Now, the Hebrew speakers among them can get help from Dr. Zipi
Ha’etzni, a clinical psychologist who has written a serious, scientifically-based
290-page volume resulting from seven years of treating hundreds of such
frustrated people in her private Jerusalem clinic. Called Lishkol Meihadash 2:
Restart (Weighing New Options 2: Getting Back on track to Leading a Healthy and
Balanced Lifestyle), it is a sequel to her first book (2009), which she meant to
be a psychological handbook for weight loss and maintenance.
on the psychological aspect of weight loss,” she told The Jerusalem Post
interview, “but it didn’t present a process on how to evade the vicious cycle of
yo-yo dieting. Only the last chapter of the previous book dealt with relapse
prevention. I learned so much about the subject from my clients in recent years
that I decided to write the sequel. Many overweight people need to have their
Heavy people “have such difficulty connecting the dots and
understanding the process. They get stuck in a loop. I have even treated people
who were alumni of weight-loss TV programs who were watched by the many viewers
who saw them escape from obesity. But after all that work and detachment from
normal society and home life, some of them regained the weight,” said Ha’etzni,
who treats many obese patients who have undergone bariatric (stomachshortening)
The Bar-Ilan University graduate, who lectures at the University
of Haifa in a program to treat the overweight using cognitive behavioral
therapy, added that she has much compassion and understanding for her
“I was overweight, even as a child, so I know what people who
need to lose weight grapple with. Today, due to a better lifestyle, exercise and
proper diet, I am within the norm.”
Born in Israel to immigrants from
Romania, Ha’etzni grew up in Canada and returned to Israel when she was 18.
Married and the mother of a 15 year old and an eight year old, she says that her
husband is overweight but not obese.
“He struggles with it, but I respect
others’ sovereignty and their choices. He has improved his lifestyle and
exercises in the morning. We don’t keep junk food at home. The problem is he
works a lot away from home and eats out most of the time. The ironic
thing is that we first met in a health club.”
The psychologist said that
when she recently removed the TV set from the living room and put it in the
dining room, she noticed there was less detrimental munching by family
As someone who does not often stay in hotels, Ha’etzni quickly
saw the effect on diet of vacationing when she and the family spent a week in
Eilat this Pessah.
“I wasn’t so hungry, but I ate more. In a luxury
hotel, you feel you’ve paid for the meals and are entitled to eat everything.
The abundance is so overwhelming. It affected me psychologically.”
the days passed in the hotel, she developed “a much better eating plan for
myself. It was much easier to choose what was good for me instead of trying
everything. There was a lot of trial and error and a learning
The 39-year-old psychologist explained that “it certainly
isn’t a sin to enjoy food. But in gaining a lot of weight, there is a
personality factor. People with low conscientiousness and high
impulsivity gain more than people with the opposite traits. They often eat as a
coping mechanism for stresses and problems.”
HER NEW book, which at the
end has a reference list of dozens of scientific books and journal articles, is
clearly professional and based on proven fact, but I nevertheless found it easy
to read from start to finish. Ha’etzni selected 101 cases of individuals and
groups she had treated who needed psychological help to halt the cycle of weight
gain, loss and re-gain.
Why 101 and not 100? Ha’etzni explains that there
is a difference between a short-term habit and a long-term one. The compilation
of ethical teachings and aphorisms by rabbis of the Mishnaic period called
Ethics of the Fathers
advocates devoting one more attempt – 101 if necessary –
to study something that could not be accomplished after 100 times.
she gives 101 lessons in the book’s 290 pages, utilizing the difficulties of her
clients (under pseudonyms) who were yo-yo dieters, most of whom changed their
way thinking and their habits, lost weight and have kept it off. Many people who
lost a significant amount of weight believe they can take it off again if they
need to, but this belief is mistaken, Ha’etzni writes.
“They think they
don’t have to plan what they eat, consult with experts to have follow-up, make
an effort or learn about new advances. Some who dieted successfully in
the past forget all the efforts they invested in it and expect to succeed based
on their past behavior. ‘No problem,’ they insist. ‘I already know what to do.
The moment I decide, everything will work out,’ they say. The problem is that
the moment arrives, and the weight keeps rising.”
Yo-yo dieters, the
psychologist notes, typically suffer from a lack of self-confidence, which is no
less harmful than their overconfidence that they can lose it again. Thus while
sure before they diet again that they can stop eating irresponsibly, after
trying to do so, they are convinced they are utter failures. This often
happens to long-time smokers as well.
Avi lost 20 kilos two years ago
without professional help. He joined a health club and found a girlfriend, but
recently parted with her. He is stressed, and when he returns from work eats
uncontrollably in front of the TV set until he falls asleep. He went to Ha’etzni
in desperation after regaining some of the weight and feeling like a
“I’m a mess, the world’s a mess and my future is even more so,”
he told her. Avi recalled that a few days before, he was at the supermarket and
saw a couple looking at him and whispering to each other that ‘it is too much.’
He thought they were saying he was obese, but in fact, upon getting closer, he
heard them complaining he had put more than 10 items of groceries in his
shopping cart even though he was in an express line.
Noting his lack of
self-confidence, Ha’etzni asked if something good happened to him in the past
week, and he remembered he had been appointed to head a new project at work and
even won a small sum with a lottery ticket.
“This story illustrates a
central idea in cognitive psychology, mood congruent memory, in which people
tend to pull out memories that suit their current moods.”

three brains,” Ha’etzni writes. “One is the reptilian brain whose role is to
save our lives at all costs; it is responsibility for automatic functions like
breathing, heartbeat and other physical activities. The second is the limbic
system, responsible in all mammals for emotions, instincts, aggressiveness and
eating and sexual behavior. This emotional brain is not very smart; it
acts from infancy to differentiate between danger and security, pleasant and
painful, attractive and repulsive and so on. This decides if we feel positive or
negative emotion towards someone,” Ha’etzni writes.
The “third brain” is
the neo-cortex, involved in thinking, judgment and values. Within it are hidden
musical and artistic abilities as well as high cognitive functioning such as
planning and organization. Scientists used to believe that this upper, rational
brain uses logical thinking, is dominant and makes us able to control our eating
But, she continues, experience shows that when a dieter violates
his diet or otherwise acts impulsively, the limbic brain takes over and controls
the other parts, causing us to act against our intentions and use the upper
brain to justify our actions.
“As long as a person has negative feelings
toward a healthy lifestyle, the emotional brain will disrupt his real effort to
change. For a person to agree to make the effort and alter his eating habits, he
must believe that the change is possible and worthwhile.”
If not, she
says, the emotional brain will disrupt his efforts. Thus she suggests focusing
on the enjoyable aspects of changing and losing weight.
42-year-old married woman and independent businesswoman, was urged by her
parents and husband to lose weight. She complained to Ha’etzni that when fat
started to drop off, they made such a fuss of every gram lost that she felt that
her closest family members had begun to treat her like a child. In an
unconscious protest and not due to hunger, she began to regain
“What began as a compliment turned into a chronic problem,” wrote
the psychologist. She helped Shira to investigate the effects of her feelings
and regain her autonomy.
The weight-loss expert recommends keeping a

then are surprised that they gain weight. After a week, mark in one color

“fillers” to assuage emotional stresses.
Yoav, a researcher himself,
discovered from the diary that he ate little at meals but overloaded on junk
food snacks the rest of the time. He was encouraged to enter into a chart what
emotions and thoughts preceded his gorging to increase his awareness of the fact
that it was not hunger that pushed him to eat.

Kalanit, who was able to eat properly and set a good example when
having dinner at her home with her grandchildren, was determined to refrain from
touching the cake they ate.
“I was very proud of myself,” she said. The
next day, however, one of the kids was so unruly that in the evening, she was so
upset that she took out the whole cake and ate it down to the last crumb. She
should not have denied herself the small pleasure, Ha’etzni advised.

losing weight, looking attractive and buying new clothes are wonderful, Ha’etzni
warns that beneficial dieting does not always solve problems. People who suffer
from clinical depression or other psychiatric disorders often think that if only
they were thinner, all their problems will be solved. When this doesn’t
come true, yoyo dieting often results. The therapist and client must be very
sensitive and courageous to understand and identify the real
Finally, one should choose one’s friends carefully. Anyone who
has bad eating habits, is jealous of your having lost weight and goes out of his
way to encourage you to have “one more bite” should be avoided as much as
possible. Ha’etzni advises choosing a “true friend” who can provide emotional
support as you sail over the “sea of fat” on the way to a safe harbor.
