  1. 1. SMALL DOSES OF T3 DURING WEIGHT REDUCING DIET IN OBESE WOMEN, INCREASE SHBG LEVELSWITHOUT FREE FAT MASS CATABOLISM A. Mortoglou Authors E. Kapantais D. Chrysohoou Endocrine & Metabolic Department Athens Medical Athens, Greece
  2. 2. Introduction It is documented that during weight loosing diets serum T3 decreases, resulting in a fall of resting metabolic rate. Treating such patients with small doses of T3, can prevent the adaptation of RMR to lower levels and increases serum SHBG. The contraindication for the use of T3 in clinical practice is the free fat mass catabolism, but this have been shown only in small number of obese persons and in combination with VLCD.
  3. 3. PurposeTo investigate the influence of T3 treatment on Qualitative weight loss and on SHBG levels
  4. 4. Study Design 8 th week 4 th week N=35 on T3 25μg •WeightN = 76 T3 determination •SHBG N=41 no- treat. •Skinfolds 8 weeks Diet with energy content: initial body weight X 10 Kcal/24h
  5. 5. Subjects and Methods  N = 76 Obese women  Age = 35 ± 12  Weight Kgr = 95.5 ± 14.9  % increase from ideal body weight = 178 ± 25  BMI = 37.03 ± 5.30  Sum of four* skinfolds mm = 120.7 ± 26  T3 ng/dl = 144.7 ± 24.5  TSH μU/ml = 2.28 ± 1.28  SHBG nmol/L= 32.04 ± 9.56* : Biceps, Triceps, Subscapular, Suprailiac Mean ± SD

  9. 9. Changes in the sum of 4 skinfolds & SHBG levels in 76Obese women after an 8 week weight reducing regimen 4 Skinfolds reduction SHBG increament 60 300 mm 50 p= 0.488 % p= 0.011 200 40 30 100 20 0 10 0 -100 Non-treated Treated Non-treated Treated group group group group Treatment: T3 25 μg/d from 4th to 8th week
  10. 10. ConclusionThe replacement of T3 fall during weight reducing diet increases SHBG levelsmore than the expected from weight loss without any further FFM catabolism
