Abstract
BACKGROUND: Type 2 Diabetes (T2D) is a global challenge with rising prevalence, inadequate compliance, and poor outcomes. AIMS: Assess the effect of a 2-only-daily-meals with exercise lifestyle (2-OMEX) on (a) HbA1c, (b) anti-diabetic medication count (ADMC), (c) Kcal intakes, body weight, fasting insulin, and subjective well-being. MATERIALS AND METHODS: This is a single-arm follow-up study conducted in a free 2-OMEX clinic in 2019-2020. Information for two meals and exercise compliance was obtained during the clinic visit. HbA1c was tested by HPLC and fasting insulin by the CLIA/CMIA method in private laboratories. RESULTS: Eligible subjects (f = 49, m = 116) completing two or more visits and 60 days of follow-up had a mean age of 55.92 (10.43) years, a T2D duration of 8.20 (6.28) years, and a median observation period of 140 days. Statistically significant changes included HbA1c decline from 7.69 (1.70) to 7.00 (1.20) gm% (equivalent by the LogNormal method to 1.088 gm%), average weight loss at 5%(m), and 2%(f). ADMC declined from 2.32 to 2.14, the difference being significant with the WSR test (z = 2.0087, P = 0.0223). Subjects attaining anti-diabetic medication-free and normoglycemic status (HbA1c < 6.5 gm%) were 20 (12%). The number attaining HbA1c ≤ 7 gm%) significantly rose from 73 (44%) to 101 (61%) with an ADMC of 1.9 (chi-square = 9.531, df1, P = 0.0020203). Participants reported 'feeling energetic' (79%), feeling lighter (50%), and better sleep (35%). Average energy intakes dropped by 120 Kcal to 1580/day. Fasting insulin remained unchanged, from 12.61 (11.06) to 12.34 (11.78) mlU/L. The dropout rate was 35%. CONCLUSIONS: The 2-OMEX lifestyle showed a sizeable, favorable, and significant change in HbA1c, body weight, ADMC use in five months, and subjective benefits. Studies are necessary for remission impact and pathways.
