In that, it is unquestionable that a woman's diet plays a minor part in the development of PCOS. Accordingly, scientists all over the world are currently trying to determine the optimal diet for people like the 60 overweight or obese patients with PCOS who participated in a recent study from the Kashan University of Medical Science in Iran (Foroozanfard 2017).
The study was designed to evaluate the effects of the Dietary Approaches to Stop Hypertension (DASH diet) on weight loss, anti-Müllerian hormone (AMH) and metabolic profiles in women with polycystic ovary syndrome (PCOS). To this ends, the scientists conducted a randomized controlled clinical trial among 60 overweight or obese patients with PCOS. Patients were randomly assigned to receive either a low-calorie DASH (N=30) or control diet (N=30; designed to mirror the traditional Iranian diet) for 12 weeks. What is particularly interesting is that both diets had identical macronutrient compositions: 52-55% carbohydrates, 16-18% proteins, and 30% total fats.
[...] provided with 7-day menu cycles that were individually planned using a ‘calorie count’ system. To facilitate the compliance to the diets, participants were given and instructed an exchange list.
The way we eat is not just obesogenic it is also acidogenic... or is the former just a consequence of the latter? Learn more!
[...] Compliance with the consumption of diets was controlled once a week through phone interviews. The compliance was also double-monitored by the use of 3- day dietary records completed throughout the study.
[...] To control for dietary intakes of subjects throughout the study, the dietitian was calling the participants to resolve their probable problems" (Foroozanfard 2017).The significant difference in the study outcomes you can see in Figure 1 are thus a function of the foods and not the macronutrient composition or the total energy intake of the women.
