Health experts have
for long recommended 'low-fat' diets to counter the obesity epidemic. Some have
now done a U-turn, telling us to eat more fat. Why?
For over half a
century, obesity and heart disease rates have been increasing. During that time
people moved away from eating natural saturated fats to eating artificial
unsaturated fats, all because of recommendations made by health experts.
Now the experts admit
that back then they were ignorant of the different kinds of dietary fats. Some
fats are beneficial while others are detrimental to health. Until now experts
have said that unsaturated fats should be consumed in preference to saturated
fats.
"Eat margarine
instead of butter" they said, and "cook with vegetable oils instead
of lard". Unfortunately, those recommendations did not prevent obesity and
heart disease rate growing.
Once the public
accepts the guidance of health experts, it becomes almost impossible to say
that the experts were actually wrong.
However, a report
published by the British National Obesity Forum and Public Health Collaboration
on Obesity entitled 'Eat Fat, Cut The Carbs and Avoid Snacking To Reverse
Obesity and Type 2 Diabetes' is different.
Based on results of
43 studies, experts now say that the policy of encouraging low-fat diets has
been bad for public health.
They now want a
radical change in official dietary guidelines because low-fat diets are based
on flawed science that has resulted in carbohydrate overconsumption.
The report states
that good fats do not make people fat. Rather,
it is snacking
between meals that increases weight gain. The low-fat, low-cholesterol messages
have had serious health consequences, with obesity rates now at their highest
ever, with no sign of declining.
Here is a summary of
the report's findings:
- You don't get fat by eating healthy fats
- High-fat, low 'net' carbohydrate diets are better than low-fat, high net carbohydrate diets for weight loss
- Stop counting calories. Nutrients are crucial for health, which is harmed when you don't eat properly. Calories have differing metabolic effects, depending on their source
- Increasing exercise does not prevent obesity. Obesity is a metabolic dysfunction leading to abnormal energy divisions
- Saturated fats such as natural fats from grass-fed cows do not cause heart disease
Ancel Keys' original
proposal in 1953 linking saturated fat to heart disease has suppressed the
truth for too long. The replacement of saturated fats with vegetable oils has
actually increased mortality, not reduced it.
Although vegetable
oils have been shown to lower total cholesterol levels by a sixth over a 12
month period, they have never been shown to improve health and longevity. In
fact, lowered cholesterol levels have been shown to increase mortality.
The latest
recommendations are to avoid foods labeled 'low-fat' or 'low-cholesterol'.
No evidence exists
proving that avoiding saturated fats or cholesterol in the diet reduces the
chances of dying from heart disease.
The report blames the
enormous food industry for influencing public health bodies to issue misleading
dietary guidelines.
All for commercial
gain...
