Our Research Results 

Discussion: Customer feedback online about Primal Lean is overwhelmingly favorable. There are virtually no complaints or negative comments by users to be found.

Primal Lean’s resume includes something that many, if not most, other diet programs lack: the backing of a randomized double-blind, placebo-controlled scientific study of its key ingredient.

The investigation by the University of Yaounde I in Yaounde, Cameroon, and the University of Ngaoundere in Ngaoundere, Cameroon, found that irvingia gabonensis “significantly reduces body weight” in overweight persons.

If you’re interested you can read the abstract of the study below. Laymen will find the abstract rather dry reading, but the information presented does provide scientific support for Primal Lean’s claims. You can find more information about the study by clicking here.

Based primarily on the scientific study as well as my personal experience with the product, we have given Primal Lean a buy-rating of five stars, our highest rating.

Study Abstract

Background

A recent in vitro study indicates that IGOB131, a novel seed extract of the traditional West African food plant Irvingia gabonensis, favorably impacts adipogenesis through a variety of critical metabolic pathways including PPAR gamma, leptin, adiponectin, and glycerol-3 phosphate dehydrogenase. This study was therefore aimed at evaluating the effects of IGOB131, an extract of Irvingia gabonensis, on body weight and associated metabolic parameters in overweight human volunteers.

Methods

The study participants comprised of 102 healthy, overweight and/or obese volunteers (defined as BMI > 25 kg/m²) randomly divided into two groups. The groups received on a daily basis, either 150 mg of IGOB131 or matching placebo in a double blinded fashion, 30–60 minutes before lunch and dinner. At baseline, 4, 8 and 10 weeks of the study, subjects were evaluated for changes in anthropometrics and metabolic parameters to include fasting lipids, blood glucose, C-reactive protein, adiponectin, and leptin.

Results

Significant improvements in body weight, body fat, and waist circumference as well as plasma total cholesterol, LDL cholesterol, blood glucose, C-reactive protein, adiponectin and leptin levels were observed in the IGOB131 group compared with the placebo group.

Conclusion

Irvingia gabonensis administered 150 mg twice daily before meals to overweight and/or obese human volunteers favorably impacts body weight and a variety of parameters characteristic of the metabolic syndrome. This is the first double blind randomized placebo controlled clinical trial regarding the anti-obesity and lipid profile modulating effects of an Irvingia gabonensis extract. The positive clinical results, together with our previously published mechanisms of gene expression modulation related to key metabolic pathways in lipid metabolism, provide impetus for much larger clinical studies. Irvingia gabonensis extract may prove to be a useful tool in dealing with the emerging global epidemics of obesity, hyperlipidemia, insulin resistance, and their co-morbid conditions.
