Study suggests low carb diet performs better than low fat diet for insulin control in diabetics

Published on July 19, 2012,

PubMed outlines research from Sweden that suggests a low carb diet improves glycaemic control more effectively than a low fat diet, despite a comparable weight loss.

Abstract

AIMS/HYPOTHESIS: The study aimed to compare the effects of a 2 year intervention with a low-fat diet (LFD) or a low-carbohydrate diet (LCD), based on four group meetings to achieve compliance.

METHODS: This was a prospective randomised parallel trial involving 61 adults with type 2 diabetes consecutively recruited in primary care and randomised by drawing ballots. Patients that did not speak Swedish could not be recruited. The primary outcomes in this non-blinded study were weight and HbA(1c). Patients on the LFD aimed for 55-60 energy per cent (E%) and those on LCD for 20 E% from carbohydrate.

RESULTS: The mean BMI and HbA(1c) of the participants were 32.7 ± 5.4 kg/m(2) and 57.0 ± 9.2 mmol/mol, respectively. No patients were lost to follow-up. Weight loss did not differ between groups and was maximal at 6 months: LFD -3.99 ± 4.1 kg (n = 31); LCD -4.31 ± 3.6 kg (n = 30); p < 0.001 within groups. At 24 months, patients on the LFD had lost -2.97 ± 4.9 kg and those on LCD -2.34 ± 5.1 kg compared with baseline (p = 0.002 and p = 0.020 within groups, respectively). HbA(1c) fell in the LCD group only (LCD at 6 months -4.8 ± 8.3 mmol/mol, p = 0.004, at 12 months -2.2 ± 7.7 mmol/mol, p = 0.12; LFD at 6 months -0.9 ± 8.8 mmol/mol, p = 0.56). At 6 months, HDL-cholesterol had increased with the LCD (from 1.13 ± 0.33 mmol/l to 1.25 ± 0.47 mmol/l, p = 0.018) while LDL-cholesterol did not differ between groups. Insulin doses were reduced in the LCD group (0 months, LCD 42 ± 65 E, LFD 39 ± 51 E; 6 months, LCD 30 ± 47 E, LFD 38 ± 48 E; p = 0.046 for between-group change).

CONCLUSIONS/INTERPRETATION: Weight changes did not differ between the diet groups, while insulin doses were reduced significantly more with the LCD at 6 months, when compliance was good. Thus, aiming for 20% of energy intake from carbohydrates is safe with respect to cardiovascular risk compared with the traditional LFD and this approach could constitute a treatment alternative.

TRIAL REGISTRATION: ClinicalTrials.gov NCT01005498

FUNDING: University Hospital of Linköping Research Funds, Linköping University, the County Council of Östergötland, and the Diabetes Research Centre of Linköping University.

Chef loses 200 pounds by creating own low carb diet plan

Published on July 18, 2012,

The Sun Sentinel is reporting how an obese chef created her own low carb diet plan to lose 200 pounds over a three year period.

Three years ago Barbara Feinstein, 57, of Boynton Beach suffered from morbid obesity, weighed 330 pounds, squeezed into size 28 jeans, was a type II diabetic and couldn’t get out of bed or walk up and down the stairs in her house without severe strain.

Her blood sugar was 400 and her blood pressure was 200/100. She was at the end of her rope.

“I am sick and tired of being sick and tired,” Feinstein said she remembers thinking.

She knew she had to make some drastic changes in her life, and that’s what she did.

Now, a size 1, Feinstein lost 206 pounds and cured her diabetes thanks to her weight loss regimen that she calls her 2 – 3 – 4 Weight Loss Solution.
