Is cutting calories making you feel
down? Here’s how to boost your happy hormones and still lose weight
Feeling deprived and depressed is common
when you’re on a diet. When you restrict what you eat, the levels of ‘happy’
neurotransmitters in your brain fall. These include the hormones serotonin and
dopamine, which are most easily produced when we eat foods containing fat and
sugar. No wonder we commit diet sabotage when we see cake!
Serotonin is essential for feeling happy,
content and calm. It also controls appetite. ‘Low serotonin affects sleep,
makes us feel depressed and turns us into chocoholics,’ says Lowri T, author of
The S Factor Diet (Duncan Baird, $16.5). Dopamine controls our willpower, and
low levels leave us susceptible to overeating, she adds.
New research by the University of Montreal
suggests that abstaining from fatty and sugary foods can have the same effect
on the body as drug withdrawal. Feelings of low energy, anxiety and hunger or
even the urge to burst into tears, are not uncommon when following faddy diets.

When you restrict your food intake, you
also restrict the essential nutrients (such as protein and fiber) you’re
putting into your body, which affects your mood, says Patrick Holford,
nutrition expert and author of The Optimum Nutrition Bible (Piatkus; $22.5).
‘Depression can be caused by sub-optimum nutrition, resulting in poor mental
and physical energy.’ So to stick to a diet, fill your shopping basket with
healthy, mood-boosting food. Here’s what to pick.
Good-mood fats
While fat - saturated and trans fat in
particular - is notoriously bad for your waistline, make sure your diet is
still bursting with omega-3 fats. Found in foods such as oily fish, flaxseed
and nuts, these fatty acids are needed for your body and brain to work
properly. Serotonin can’t be found in food, but your body makes it when you eat
foods rich in tryptophan, such as those containing omega-3. A study of women
suffering post-natal depression, by the University of Montreal, found omega-3
fatty acids helped increase serotonin levels in the brain.

Carry on with carbs
Tryptophan is also found in high-protein
foods such as eggs, chicken and beans. However, this doesn’t mean that people
following high-protein diets are the happiest summers. Once tryptophan is
converted to serotonin, it has to be absorbed by the bra n to give you an
emotional boost, says Turner.
Insulin, released when you eat carbs, helps
the brain absorb serotonin, but while bread. cakes and pasta made with white
flour are on the naughty list if you want to lose pounds, eating wholegrain and
slow releasing carbohydrates such as sweet potatoes and brown rice are
diet-friendly options. These will fill you up and keep you smiling for longer.
Motivation equation
High-sugar
and high-fat foods, along with caffeine and alcohol are best at stimulating
dopamine production, says Turner.

But when we eat these, our dopamine receptors are overstimulated and it’s
harder to control cravings. When you’re trying to lose weight, eating healthy
food high in tyrosine the precursor to dopamine is the best way to keep your
willpower intact and dopamine stable. Tyrosine-rich foods include almonds
bananas, fish and soy. Plus, exercise regularly and have lots of sex to keep
your dopamine receptors stimulated, the healthy way. High-sugar and high-fat
