Extracted from the report, with my interpolations

<<Individuals were eligible for the study if they were men aged 30–70
y; had a body mass index (in kg/m2) of <=30; had a history of stable
type 2 diabetes meeting the criteria of the National Diabetes Data
Group (17),

with a fasting blood glucose concentration of 8.33–11.10 mmol/L and a
serum glycated hemoglobin (Hb A1c) concentration of <=9% (mean of
values taken in weeks -2 and -1 of the study); >>

FBG this high and not on insulin or Metformin?

<<and had mild-to-moderate hypercholesterolemia, with a stable serum
total cholesterol concentration of 5.17–7.76 mmol/L and
triacylglycerol concentration of <=5.65 mmol/L (mean of weeks -2 and
-1). Individuals whose diabetes was controlled with diet only or diet
plus oral sulfonylurea agents were eligible for study.>>

See above

<< Individuals were excluded from the study if they had medical
conditions or were taking medications or supplements that might have
interfered with glucose, insulin, or lipid measurements.>>

?

...<<During the dietary stabilization phase, subjects received
instruction on a traditional weight-maintaining diabetes exchange diet
providing <=30% of total energy as fat, <=10% of energy as saturated
fat, and >=55% of energy as carbohydrate. Diet was not the major focus
of this intervention and the main goal of dietary instruction was to
encourage subjects to maintain their same dietary patterns throughout
the study. Subjects continued with this diet and received ongoing
dietary counseling throughout the remainder of the study.>>

No comment

And from later in  the report

<<The low energy intakes reported by both the psyllium and placebo
groups in this study indicated that subjects substantially
underreported their food intakes. More intensive training of subjects
is required to ensure accurate self-reported intakes for careful
dietary studies.>>
