Nutrition experts debunk certain claims about weight-loss
supplements and reveal possible health risks.
Myth #1: Weight-loss supplements are approved by the United
States Food and Drug Administration (FDA).
Truth: The US FDA does not have the authority to review
dietary supplement products for safety and effectiveness before they are
marketed. It only steps in when a “dietary supplement” is found to contain
harmful substances.
Myth #2: Weight-loss supplements alone are enough to lose
pounds.
Truth: Weight-loss supplements cannot substitute for
healthy eating and regular exercise. Many weight-loss supplements’ labels
include a disclaimer that they do not guarantee a specific weight-loss benefit,
that individual results may vary and, to get the most benefit, they must be
combined with proper diet and exercise.
Myth #3: Supplements like Hoodia, green tea and bitter
orange aid in weight loss.
Truth: Green tea, bitter orange and the African herb hoodia
have not been scientifically proven to burn fat. In fact, hoodia has not been
studied in humans. It is also unclear if it curbs appetite. Green tea contains
a fair amount of caffeine, which may result in some weight loss initially, but
it will not burn fat. Too much caffeine can affect the heart rhythm and disturb
sleep. Bitter orange has synephrine, an alkaloid found in plants, that can be
dangerous to health as it increases heart rate and blood pressure.
Myth #4: “Natural” is safe.
Truth: Some weight-loss supplements containing “natural”
ingredients like herbs comfrey or kava may be harmful to the liver. Claims that
“natural is safe” is not always true.
Safety depends on the supplement’s chemical makeup and what
it does to the body, how it is prepared and the dosage used. Also, while an
individual supplement may be safe, the combination of several products may be
risky. If you are under medication, it is best to consult your doctor first
before taking any weight-loss supplements as they may affect the efficacy of
your medicines.
While some supplements may result in weight loss in the
short term, they may have long-term adverse effects on the body, which may not
be able to handle the stress of dramatic weight loss or process artificial food
and supplements. They may be unsafe for those with existing medical conditions
or those who need to lose a lot of weight.
If you feed your body the right kinds of food, avoid
unhealthy snacks and adopt other healthy habits, you should be able to
rebalance and reboot your metabolism naturally. Nothing beats fresh and good
food to improve health and promote healthy weight loss.
