Yet another study shows no difference between low fat and low carb diets ...

for weight loss and metabolic risk factors, this time in overweight/obese subjects with impaired glucose regulation.

Background and Objectives: The aim of this study was to compare the effects of low-carbohydrate diet (LCD)
versus low-fat diet (LFD) on weight loss, glycemic control and metabolic risk factors in individuals with impaired glucose regulation (IGR) after 10-week intervention. Methods and Study

Design: In this 10-week randomized controlled trial, 90 obese/overweight adults with IGR were randomly assigned to consume either lowcarbohydrate diet (20%-25% energy from carbohydrates, 30%-45% energy from fat, 40%-45% energy from protein), or low-fat diet (40%-55% energy from carbohydrates, 20%-30% energy from fat, 20%-30% energy from
protein), or heath education (HE) group. The anthropometry and body composition were collected at baseline,
week 4, week 8 and week 10. The glycemia and metabolic indicators were assessed at baseline and week 10.

Results: A total of 69 participants (mean±SE age: 39.2±1.0 years, 72.5% women) completed the intervention and
were included in the final analysis. At week 10, all three groups presented similar mean reduction in weight (LCD:
5.80±0.6 kg; LFD: 6.36±0.57 kg; HE: 4.49±0.98 kg), and fasting blood glucose (LCD: 0.73±0.13 mmol/L; LFD:
0.84±0.17 mmol/L; HE: 0.58±0.14 mmol/L). Additionally, there were no differences in the improvements of TG
and liver function markers between diets, the low-fat diet exhibited more favorable effects on TC level.

Conclusions: Both diets achieved similar weight loss, fasting glucose, and insulin reduction in short-term, suggesting
each diet pattern could be an effective strategy for the prediabetes management

Makes no mention of the actual amounts though - if someone was to eat 2000 calories a day, then 500 might be carbs, on the low carb diet, which would be 125gm of carbs a day. The low carb group diet is also higher in protein.
I have done many diets in my life and never seen any weightloss on 125 gm of carb, nor on 75gm either, even if restricted to 1000 calories a day so I'd have put a spanner in the works - though I would have probably been weeded out as an anomaly in the early stages of the triials.

I did think that their nutrient numbers looked higher in protein and lower in fat % of calories than I'm usually eating, though I'm not eating 2000 calories so maybe if I was eating more it would be higher % protein.

I would hope that they didn't exclude anyone for not reacting as they expect, and that the numbers completed only exclude those who chose themselves not to continue. I like that they have given the standard error/deviation lines to their best fit means.

I am always outside what is expected - I eat two small meals a day and have under 40 gm of carbs. According to experts I am either lying, or I should be stick thin or dead long ago.
With my requirements being so low I can feed myself on salmon, steak or whatever I fancy, make icecream from eggs and cream with the best real vanilla or creme de menthe - so it isn't a bad thing really.

Yes, because otherwise it'd be fraud, pretty much. The paper has details on the inclusion/exclusion conditions and details of drop-outs.
