The trouble is that on Dr. Oz’s website, he doesn’t promote safflower oil for weight loss. In fact, his sponsored writer says it is way too soon to start using safflower oil.
In looking at safflower oil, the human studies seem to be using it as a placebo when doing trials on CLA (conjugated linoleic acid). CLA has come out as worse than placebo, which gets translated as safflower oil being good for you. But more recently, the CLA people have shown that CLA isn’t as bad as other studies made it appear. It doesn’t actually hurt overweight men in terms of heart attack risks.
What is bizarre is that safflower oil got any press at all, because the supposed star of that CLA/safflower study was supposed to be CLA. (Abstract below). CLA dropped body weight, not safflower oil. Safflower was just the placebo control.
So what are we to assume from this study? That eating good fats are good for you. Are they magic weight loss? If used to replace processed snack cakes, absolutely. If added to a vegan, raw food diet? Not so much.
For some reason, safflower fever has swept the globe. I have elaborated further with thoughts and research:
Will Safflower oil help diabetic mothers and underweight babies? (Using the rat research and thinking about what it might do to people).
And finally, how much Safflower oil do we really absorb (and how much of that is Vitamin E)?
The weight-loss research is below:
Comparison of dietary conjugated linoleic acid with safflower oil on body composition in obese postmenopausal women with type 2 diabetes mellitus.
Weight loss may improve glucose control in persons with type 2 diabetes. The effects of fat quality, as opposed to quantity, on weight loss are not well understood.
We compared the effects of 2 dietary oils, conjugated linoleic acid (CLA) and safflower oil (SAF), on body weight and composition in obese postmenopausal women with type 2 diabetes.
This was a 36-wk randomized, double-masked, crossover study. Fifty-five obese postmenopausal women with type 2 diabetes received SAF or CLA (8 g oil/d) during two 16-wk diet periods separated by a 4-wk washout period. Subjects met monthly with the study coordinator to receive new supplements and for assessment of energy balance, biochemical endpoints, or anthropometric variables.
Thirty-five women completed the 36-wk intervention. Supplementation with CLA reduced body mass index (BMI) (P = 0.0022) and total adipose mass (P = 0.0187) without altering lean mass. The effect of CLA in lowering BMI was detected during the last 8 wk of each 16-wk diet period. In contrast, SAF had no effect on BMI or total adipose mass but reduced trunk adipose mass (P = 0.0422) and increased lean mass (P = 0.0432). SAF also significantly lowered fasting glucose (P = 0.0343) and increased adiponectin (P = 0.0051). No differences were observed in dietary energy intake, total fat intake, and fat quality in either diet period for either intervention.
Supplementation with CLA and SAF exerted different effects on BMI, total and trunk adipose mass, and lean tissue mass in obese postmenopausal women with type 2 diabetes. Supplementation with these dietary oils may be beneficial for weight loss, glycemic control, or both.
