Free radical v antioxidants
Free radicals are atoms or groups of atoms with an
odd (unpaired) number of electrons in the outer shell
that tend to be highly reactive and seem to cause
ageing (senescence), degenerative diseases, and
cancer. They are often formed when oxygen interacts
with certain molecules.
The amino acid tyrosine manufactures
the neurotransmitters noradrenalin and
dopamine, whose positive e?ects we know
about.
Exercise releases endorphins, which help
to make us feel happier, calmer, and more
alert. Exercise stimulates Corticotropin
Releasing Factor (CRF), which suppresses
appetite. Neuropeptide then ‘tells’ the body
to eat ‘good’ food – so it can perform more
exercise.
Even armed with this cognitive
restructuring, clients (and us) may still su?er
from cravings and, perhaps, bingeing.
Cravings are thought to be the body’s way
of demanding a certain type of food that it
needs. Cravings are often linked to mood
swings. They can be eliminated by eating a
healthy diet.
Bingeing is not just giving in to a craving,
it’s eating for eating’s sake. Bingeing often
results from an emotional upset. So, it’s
clear which part of the brain people are in
when they binge!
Cravings can be avoided by:
? Knowing the triggers and avoiding them
? Avoiding emotional triggers – ?nd a new hobby.
? Recognising eating habits – ask yourself, “Do I need to eat that now?”
? Taking plenty of exercise to burn o? the calories
? Using distractions – and forget about food.
? Not denying yourself food – eat plenty of ‘good’ food. That’s a balanced diet with
vitamins and mineral salts.
So, what’s wrong with the common diets people try – let’s summarise:
? Low-calorie diets – boring, causes muscle loss (including heart muscle), doesn’t
change eating patterns once the diet is over.
? F-plan diet – boring, ??????????????????????????+??????????????????????????????????????????????????????????L????????????)?????????????????????+??!??????????????????L?????????????????????????????????????????)?????????????????????+??!????????????????????????????????????L??????????????????????????????)??????????????????????????????????????????????????????????????????????)??????A?????????????????Y????????????????,???????????????+??!???????????????L????????????????????????????????????????????+????????????????????????L???????????????????????????????????????????()????????????????????????????????????)????????????????????????????????????????)??????????????????????????????e?????)??????????????????????L?????????????????????????????? ?)Y????????L??????????????????????????????)?????????????????????????????????????????????)??????????????????)Y?????? ??L????????????????????????????????)?????????????????????????????????????????????)????????????????????????????????????????????) ???????????L??????????????????????????)???????????????????????????????????????????????)?????????????????????????????????????????)?????????????????)=????????????????????????????????????)A????)?????)I?????)?????????)A???)I????????)?????????????)=?????)??????) ????)=??????????????????????????????????)???????)i?????L???????????????????????????????????)???????????????????????????????????????????)????????????)M????????L????????? ?????????????????????????)??????????????????????????????????????()M?????????????????????????????????????????????????????e?????????????)???????????????????e??????????????????????????????????????????????????????)????????????????????????????????%???????????????????????????????????????)?????()I????????()9??????????????????????]??????????e?]???????]???e??
