Fat v Glucose
Dr Laurence Gerlis IDDT
1973-Sleeper (thanks to C4)
• This morning for breakfast he requested something called "wheat
germ, organic honey and tiger's milk."
• Dr. Aragon: [chuckling] Oh, yes. Those are the charmed substances
that some years ago were thought to contain life-preserving
properties.
• Dr. Melik: You mean there was no deep fat? No steak or cream pies
or... hot fudge?
• Dr. Aragon: Those were thought to be unhealthy... precisely the
opposite of what we now know to be true.
• Dr. Melik: Incredible
• (see also) Nina Teicholz The Big Fat Surprise
3.2 million people with diabetes
• 90% type 2
• 850,000 undiagnosed
• 6% of UK adults
• Important- young people and children with
type 1 diabetes need to grow- carbs needed
Conversation September 1st
• Me: Do you have any illnesses or take any
medication?
• Patient (BMI 30) : No
• Me: Your urine is full of sugar
• Patient: It’s only type 2 diabetes- I haven’t
taken the tablets for a week.
Cardiovascular mortality
• In the days before statins there was a major
concern about heart disease and diabeteshence the start of the anti-fat campaign
• See Le Fanu-there was a cohort of men whth
cardiovascular disease int he 1960s/70s
Low fat diet
•
•
•
•
•
Thus high carbs were introduced
Patient admitted to hospital “Diabetic diet”
Yellow form stuck above bed “Diabetic”
No distinction type one or type two
3 meals and 3 snacks daily high carb!
Obsession with type 1
•
•
•
•
•
Thus high insulin to match carbs
Not appropriate even for type 1
Fear of “coma”
DKA or Hypos?
The word diabetes still strikes fear and panic
into many doctors and nurses
7 fruits a day!!

Orange juice is synonomous with “healthy”
150ml orange juice=69G=16 teaspoons sugar
Lim BMJ Low carb diet=lower trigs better HDL.

Van Tulleken Twin TV programme

•
No diabetes and not overweight
One had zero fat diet other zero carb diet
Both diets miserable
Pointless experiment
Patient JC
• Age 60 previously lost 5.5 stone on Atkins diet
• Has lost 1.5 stone in one month on Atkins
• Needs cholesterol check
Saturated fats beat diabetes
• Dairy products eg yoghurts reduce risk of type
2 diabetes
• Odd chain (odd number of carbon atoms)
saturated fatty acids are good for you basically
more dairy products.
Fizzy drinks
• Prof Ian MacDonald SACN working group:
• “There is an association between sugar
sweetened beverages and type 2 diabetes.”
• In my personal view this is the number one
current Public Health issue, more than
cigarettes (helped by smoking ban in pubs)
and alcohol (already on radar)
Fat
• When you take the fat out the food tastes
worse-so the food industry have added more
sugar.
• Statins are very useful medications despite the
various side effects.
Current NHS advice for type 2 Diabetes
• You can make adaptations when cooking meals, such as
reducing the amount of fat, salt and sugar, and increasing
the amount of fibre.
• You don't need to completely exclude sugary and high fat
foods from your diet, but they should be limited. It's
possible to achieve good blood glucose control by
including sugary foods in your diet.
• The important thing in managing diabetes through your
diet is to eat regularly and include starchy carbohydrates,
such as pasta, as well as plenty of fruit and vegetables. If
your diet is well balanced, you should be able to achieve a
good level of health and maintain a healthy weight.
Bristol study
• Insulin use in type 2 has increased 7 fold
• 1991 to 2010
• Once you are on insulin, you are much more
committed to carbs to avoid hypos.
