Low Carb Diet Hurts Memory!
Big, Carb-Heavy Breakfast Aids Weight Loss!
Atkins Diet IncreasesAll-Causes Mortality!
Deep Breath!
Headlines:
Designed to sell newspapers and magazines
Never subtle
Subtlety is where the truth lies!
The ________ Media!
Supported by advertising Food processors Drug industry
What happened to the Incredible Edible Egg???
Is Beef still What’s for Dinner???
Consider the Source
What is the publication?
Who is the author? Credibility? Obvious bias?
Read the article Any new information, or just the
same old canards?
Studies
Observational (most are this type) Correlation is NOT causation! Maybe suggestive, never conclusive.
Clinical How many subjects? Over what period? Closely monitored? What was the actual diet? Multiple variables?
Comparison of Weight-Loss Diets with Different Compositions of Fat,
Protein and Carbohydrates
“No difference in diets for weight loss”Clinical study, 811 (645) participants
The diets: 20% fat, 15% protein, 65% carb 20% fat, 25% protein, 55% carb 40% fat, 15% protein, 45% carb 40% fat, 15% protein, 35% carb
Reading more closely…“Low-Carb” = 35% calories from
carbohydrates, or 137 grams???
Only 40% from fat??? (I shoot for more like 70-75%.)
Reported intakes did not reach target levels of macronutrients!
They never actually tested a low-carbohydrate diet!
10% of participants kept off 10% of their body weight. Success?
Atkins Diet Increases All-Cause Mortality!
by Dr. Dean Ornish
(Gosh, we’re awfully impressed, I can tell you!)
Annals of Internal Medicine
“Meat Intake and Mortality: A Prospective Study of Over Half a Million People”
Reading more closely…
“Prospective” = “Observational”
“Meat intake was estimated from a food frequency questionnaire…”
Big assumptions: Accurate memory of what you ate Food intake remains the same for
a decade
So, how did this one work? “High animal protein” and “high
vegetable protein” groups Broke into deciles by carb intake Men vs Women “Lowest carb” group still 37%, or
168 grams carb “Low-carb”/high-veg group was
even higher over all Men ate more carbs than women.
NO GROUP was close to “low-carb”
Furthermore….. “High-veg” group actually ate more
animal protein than vegetable! Lowest 2/3 of “low-animal” group
ate more animal protein than “high-animal” group!
Lowest 2/3 of women’s “low-animal” group ate more red/processed meat than “high-animal” groups!
Differences persisted with the men. Where did the animal group’s carbs
come from? Had to be sugar.
What did this demonstrate?
NOTHING!Except an overwhelming desire of
some people (ahem-Ornish-ahem!) to “prove” that animal foods are bad and plant foods are good.
Next: Multiple Variables
The “Big Breakfast” Study 94 obese women with metabolic
syndrome Put on either a “low-carb” or a “big
breakfast” diet “Low-carbers” did a little better in first
four months, then regained “Big-breakfasters” continued to lose
Reading more closely…
Calories: Low-carbers ,1085; big-breakfasters, 1240. Huh?
Carbs: LC, 17 g; BB, 97 g. Fat: LC, 78 g; BB, 22 g. Protein: LC, 51 g; BB, 93 g. Huh? Breakfast size: LC, 290 calories,
25% of daily calories; BB, 610 calories, nearly half daily calories.
SIX (count ‘em SIX) Variables!
Caloric intake Fat intake Carbohydrate intake Protein intake Breakfast size Weighting of caloric intake toward
beginning/end of day
So, who did what to whom?
And what’s with this?
Bad math! What low-carb diet restricts you to
1000 calories a day? What low-carb diet restricts
breakfast size? Only 51 grams or protein a day?
Straw Man Argument!
Low-Carb Diet & Memory Loss
19 women, aged 22 to 55 9 low-carb, 10 low-calorie Week 1: low-carbers showed
decreasing memory and slowed reaction time
Week 2: carbs added back, cognition skills “returned to normal”
Wait a minute now… First week was essentially zero-carb.
(Do you remember your first week?) Just getting to Induction by the end
of the study – and their cognitive problems vanished!
Even in Week 1, low-carbers still out-performed on “attention vigilance task”
Once again, someone is “creating a reality” they only wish were true.
Low Carb Diet Best for Lowering Blood Pressure
(Now we’re talking!) 146 obese subjects with comorbidities
(diabetes, elevated cholesterol & triglycerides, hypertension)
Half put on low-carb, half on low-fat with orlistat (aka xenical or “Alli”)
Low-carbers were on Atkins induction – an actual low-carb diet!
So, how did they do? Low-carb group lost 9.5% of their
body fat; low-fat group lost 8.5% (even while taking the orlistat)
Both improved cholesterol and trigs Insulin & glucose markers improved
only in low-carb group BP improved far more dramatically
in low-carb group 47% of low-carbers discontinued BP
meds vs 21% of low-fat group
In summary, ask yourself…
Do I trust the source? Is there actual science involved? Observational or clinical study? How big? How long? How was it
constructed? Was it really low-carbohydrate? Do the headlines match the actual
conclusions?
