Clinically Proven Weight Loss

Pederson S et al, Arch Intern Med. 2007;167:1277-1283

Endocrinologist Dr. Sue Pedersen's paper finds that people with diabetes using a portion control tool lost as much weight as they would on medication, without the side effects.

Dr. Sue Pederson

"The weight loss we saw is similar to studies using weight loss medication but without the potential side effects, or the expense."

The optimal management of type 2 diabetes involves lifestyle change including dietary modification, increased activity levels and weight management. Portion size is an important of energy intake. However, empowering people to achieve a sustainable hypocalorific and nutritionally balanced diet can be difficult and time consuming. Published in the Archives of Internal Medicine this randomized controlled trial of The Diet Plate  in obese people with type 2 diabetics investigated the efficacy of a portion control plate to induce weight loss and improve diabetes management.

Dr. Ian Campbell

"The Diet Plate puts control back in the hands of the individual and makes it much easier for everyone who wants to lose weight."

130 obese people with type 2 diabetes (55 treated with insulin) were randomized to either daily use of a portion control plate (The Diet Plate) or to usual dietary advice. Subjects were supported with up to four 2 minute phone calls over the six month study period.

The study showed that:

  • 17% of patients on The Diet Plate experienced clinically significant weight loss (5% or more) compared to only 4.6% of people not using The Diet Plate (control group)
  • After 6 months people using The Diet Plate lost significantly more weight than the control group (1.75% vs 0.05%; absolute values 2.1kg vs 0.1kg)
  • The clinically significant weight loss seen in the study is comparable to weight loss seen in type 2 diabetes in studies of weight loss medications
  • 26% of The Diet Plate users experienced a decrease in diabetes medication requirements, compared to 11% of the control group
  • Conversely, 34% of the control group required an increase in diabetes medications at 6 months compared to only 14% of the intervention group
  • The Diet Plate users on insulin on average decreased their insulin by 8 units per day; the control group had to increase their insulin by 7 units
  • Clinically significant weight loss was observed regardless of age, gender, education, baseline weight, or medication use
  • Patients using The Diet Plate had a slight improvement in non-HDL cholesterol
  • No adverse effects were seen, other than mostly mild drops in blood sugar, that resolved by decreasing diabetes medication
  • The success of The Diet Plate in this population lends great optimism towards the likelihood of success in non-diabetic overweight and obese individuals
