Dumb diet study tests 50% carbs (called Low Carb/High fat) vs 60% carbs (called Low fat)

A study with obese children tested the difference between what researchers call a "high fat" diet, vs a Low fat diet. Most of these study diets I've seen are ALL very high in carbs, and seem to follow the "healthy Plate" USDA that promotes 45%-65% carbs/via grains a day.
For KETO dieters this seems crazy, right? They didn't find much different at the end, because, to me, they diet was too similar to start with!!!
In both cases the amount of carbs is VERY HIGH..no where near ketosis of <20-30 carbs a day,
(2400 calories with 50% carbs is 1200 calories, and 60% is 1440 calories.
the 5% difference in FATS seems negligible…. 88% of kids kept to the higher fat diet, with only 75% to low fat…..a small difference in satiety/pleasure
Dietary restriction in obese children and its relation with eating behavior, fibroblast growth factor 21 and leptin: a prospective clinical intervention study
The L-CHO diet was 50 % carbohydrate, 30 % fat and 20 % protein, while the Low Fat diet with 60 % carbohydrate, 25 % fat and 15 % protein.
Conclusions
In conclusion, to our knowledge this is the first study to compare the effect of carbohydrate or lipid restriction on appetite traits in obese children. Both types of dietary restriction improved the metabolic parameters. Leptin and FGF21 decreased with both diets. Leptin was correlated with BMI and FGF21 was associated with triglycerides, total cholesterol and BMI, but after the L-CHO and L-F diets, only triglycerides remained associated with FGF21.
Before the diet, satiety was associated with less screen time, but after the diet, appetite traits were not associated with life-style, hormonal or metabolic factors. In this study we did not find important behavioral, metabolic or hormonal differences between both types of diets. Further studies are required to properly identify changes induced with different amounts of macronutrients.
