Tuo paperi oli kirjoitettu melko asenteellisesti mikä ei ollut mikään yllätys, kun Zone-dietin "keksijä" Sears oli yksi kirjoittajista..

Mielenkiintoista(joskaan ei mitään mullistavaa) dataa pätevässä tiedeläpyskässä, olkoonkin Sears mukana. :D

"Participants and study design
Sedentary, overweight men and women [aged 20–60 y; body mass index (BMI; in kg/m2) > 25] were screened for diagnosed disease and use of prescription medications. Participants (n = 20) were stratified by age, sex, and BMI and randomly assigned to 1 of 2 experimental diets: the ketogenic LC (KLC) diet or the low-fat, nonketogenic LC (NLC) diet.
All participants gave written informed consent. The Institutional Review Board of Arizona State University approved the study protocol.
During the 6-wk feeding trial, all food and beverages were provided to participants, who remained sedentary. Hot lunches were prepared and served to participants Monday through Friday at the test site. Breakfast, dinner, and weekend meals were prepared and packaged for participants to take home. After the 6-wk trial, participants were instructed to continue following their diet plan (KLC or NLC) on their own for 4 wk. A registered dietitian discussed the diet details with each participant and provided daily meal plans and recipes for these 4 wk.
Before the start of the trial and at weeks 2 and 6, participants provided a 24-h urine sample; the next morning, resting energy expenditure (REE) was measured after a 12-h fast and a 24-h avoidance of light-to-heavy activity. A fasting blood sample was collected from participants at trial weeks 0, 2, and 6.
Experimental diets
The protein content of the 2 experimental diets was comparable— 30% energy—but the KLC diet was high in fat (60% of energy; saturated fat, 21% of energy) and very low in carbohydrates (beginning with 5% of energy), whereas the NLC diet was low in fat (30% of energy; saturated fat, 9% of energy) and carbohydrates ( 40% energy). The carbohydrate content of the KLC diet was increased by 5 g/wk in weeks 3–6, and subjects following this diet were instructed to consume 40 g carbohydrates/d during the self-monitored phase of the trial. The NLC diet had 67% of the recommended dietary intakes for the micronutrients; the KLC diet was less nutritious: fiber, vitamin E, folate, iron, magnesium, and potassium were <67% of recommended dietary intakes.
All participants were provided a daily multivitamin and mineral tablet beginning at the second week of the 6-wk trial. Within diet groups, participants consumed similar meal plans, but daily energy intakes were individually adjusted by altering portion size to provide 70% of that needed for weight maintenance."

Hiukan sivuten tuota tutkimista, onko miten yleistä että lopputulokset mitataan ns. tasavertaisesti, eli uhrit olisi jonkinlaisella tasaus jaksolla diettien jälkeen että voisi 99% sulkea painon vaihtelut esim. eri diettien nestetasapainoon tai lihasglykogeeniin vaikuttavien tekijöiden osalta? Sama olisi varmaan aiheellista esim. placebo vs. kreatiini tutkimuksissa..
