What an amazing find, as I am reading more about low carbing.

Obese children who were fed a low carb diet lost weight and improved
blood lipids. These children also ate 66% more calories than controls,
who ate "heart healthy" starches and whole grains. What a surprise.

Sondike S, Jacobson, Copperman. The ketogenic diet increases weight
loss but not cardiovascular risk: A randomized controlled trial. J
Adolescent Health Care 2000; 26: 91.

Schneider Children?s Hospital in New Hyde Park, N.Y

This study was conducted on overweight children aged 12 to 18. They
were between 20 and 100 pounds overweight. The children were split
into two groups. One group ate a conventional low-fat, carbohydrate
based "slimming" diet composed of whole grains, fruits and vegetables
with fat-free dairy products, low-fat meats, poultry and fish. Their
total intake was limited to 1,100 calories per day. The other group
ate a high-fat, low-carb diet in which they were allowed to eat as
many calories as they wanted in the form of untrimmed meat, cheese,
eggs, poultry and fish. Their carbohydrates came from two salads a day
and minimal other carbs.
RESULTS Despite consuming on average 66% more calories per day, after
12 weeks the children consuming the low-carbohydrate diet lost more
weight than those following the low-fat, high-carb plan:
Low-carb Low-fat
Calorie intake 1830 1100
Weight loss 19 lbs 8.5 lbs
HDL Increased Decreased
Triglycerides -52% -10%


As high-protein/fat diets are thought to have adverse effects on
kidneys and liver, kidney and liver functions were regularly
monitored. They were found to be unaffected by this diet.

COMMENT: Six to twelve months later, most of the low-carb dieters had
maintained their new lower weight. This study provides additional
evidence for the efficacy of a low-carb weight loss programme
specifically for the most vulnerable group ? teenagers.


I think this is a great result (and in line with every other result
regarding low carb), but unless they counted calories for the kids
before
putting them on the diet then counted calories for the kids after
they put
them on the diet, the calorie difference isn't really scientific.


Well, these were two groups of children dieters, assigned
randomly. The low carb kids ate a lot more calories than the
conventionally dieting kids.

That low carb children could eat more, surprised me.

Actually, almost every study that looks at calories and low carb comes
up with the same results. However, some people are adamant (sp?) that
if you took these people and put them in chambers to measure every
calorie, there's no difference in low carb and high carb. There was one
study that used twins and did this and determined no difference between
low and high carb. However, most studies support the "low carb = more
weight loss" hypothesis. Have you seen these:

Increased Dietary Protein Modifies Glucose and Insulin Homeostasis in
Adult Women during Weight Loss (Journal Abstract) Added on: 4/29/2003
Hits: 263
From the University of Illinois at Urbana-Champaign and the Journal of
Nutrition, 2003: In this study, researchers placed two groups of women
on two diets, each of which was equal in calories and fat. One group was
on a high protein, low carbohydrate diet and the second was on the
USDA's low protein, high carbohydrate diet. The researchers noted that
both groups lost 16 pounds on average, but the low carbohydrate, high
protein group lost more body fat and less lean body mass than did the
USDA food pyramid group. The researchers also noted that women in the
high protein group had more stable glucose levels,lower insulin levels,
and lower cholesterol levels.


High-Protein Beats High-Carbohydrate for Weight Loss in Low-Fat Diets
(Magazine Article) Added on: 12/27/2002 Hits: 1145
From the Arizona State University and the the Doctor's Guide, 2002:
This team of researchers compared the thermogenic effects of two
different low fat diets. The first low fat diet was high in protein and
the second was high in carbohydrate. The researchers found that the
study participants' body temperature and resting energy expenditure was
100% greater after eating high protein meals that after eating high
carbohydrate meals. They concluded that the thermogenesis that occurs
after high-protein meals may partially explain the effectiveness of
high-protein diets for weight loss.

(From http://www.lowcarbresearch.org/lcr/r....asp?catid=199)


Sounds like it should have been stated as:

The researchers found that the study participants' body temperature was
greater after eating high protein meals compared to those eating high
carb meals. They also found that after eating high protein meals the
resting energy expenditure was 100% greater for the low carb group than
the high carb group.

The temptation to save a few words in an abstract created a potential
for confusion.

Nice article....

Thanks for drawing attention to it.
