“…In other related studies, there is evidence that the efficacy of KD is tied to sex [ 36 ]. Though TG was not expected to decrease in women taking oral contraceptives [ 37 , 38 ], its drop can be attributed to the fact that, in parallel to this group, a decrease in body weight was also observed [ 39 ]. This was manifested in BMI, a reduction in appetite and lipogenesis, and an increase in lipolysis, the energy cost of gluconeogenesis, and the thermal effect of proteins [ 40 ].…”

Effect of a Ketogenic Diet on the Nutritional Parameters of Obese Patients: A Systematic Review and Meta-Analysis

et al. 2021

The effect of a ketogenic diet (KD) on biochemical parameters and nutritional status has been the subject of debate over the years, as several randomized clinical trials (RCTs) obtained different results. Method: A systematic review and random-effects meta-analysis of RCTs comparing KD with a balanced diet was performed by means of a search of PubMed, Cochrane Library, Scopus, and Web of Science. Trials where the method for measuring the response variables was unclear, those that considered pathologies other than chronic non-communicable diseases and those with participants receiving pharmacological treatment for obesity were excluded from the comparison. Results: Of the studies included in the meta-analysis, no statistically significant standardized mean differences were observed for body mass index (BMI) (d = −0.457, p = 0.359), total cholesterol, COL-T (d = 0.230, p = 0.591), high-density lipoprotein, HDL (d = −0.028, p = 0.934), low-density lipoprotein, LDL (d = 0.528, p = 0.173), or triglycerides, TG (d = −0.283, p = 0.222), with high values of heterogeneity. The percentage of women included in the studies is a significant moderating variable in terms of BMI ratio (z = −6.68, p < 0.001) and TG (z = −2.27, p = 0.023). Conclusion: A KD shows no more benefits on nutritional parameters than a balanced diet, and adverse effects of being on the diet are sometimes reported.

Background Although remote dietary counselling practices have increased in the COVID‐19 pandemic, it is not known which method is more effective. This study aimed to determine the effect of diet counselling by phone or video on weight loss and to compare it with the traditional follow‐up method. Methods Forty‐six participants living with obesity were randomised into the phone counselling ( n = 15), video counselling ( n = 15), and traditional follow‐up groups ( n = 16), and were followed for 10 weeks. The anthropometric measurements, quality‐of‐life questionnaire (SF‐36) scores and total calorie/macronutrient intakes were recorded and compared at baseline and at the end of the study. Results In the phone counselling, video counselling and traditional follow‐up groups body weight (−4.8 ± 0.9, −5.7 ± 1.8 and −3.3 ± 0.8 kg, respectively) and SF‐36 general health scores (14.2 ± 4.2, 15.9 ± 3.6 and 10.2 ± 3.7, respectively) of the participants changed significantly compared to baseline (group × time interaction, p < 0.05). The change in the body weight and SF‐36 general health score was more in the phone counselling and video counselling groups relative to the traditional follow‐up group (group × time interaction, p < 0.01). The highest decrease in total calorie (−301.4 ± 112.2 kcal) and carbohydrate (−26.6 ± 11.2 g) intake was in the video counselling group compared to the other groups (group × time interaction, p < 0.01). Conclusion Video counselling and phone counselling were effective in weight loss in the COVID‐19 pandemic. It is important to maintain remote dietary counselling practices to support weight management when face‐to‐face meetings are not possible.

“…In obese individuals, a previous systematic review has shown that mild low carbohydrate diet (40% of total energy) was not associated with decrease in fat mass [ 36 ]. Recently, a randomized control trial with 57 women (age 40 ± 3.5 years, BMI 31.1 ± 2.6 kg∙m −2 ) yielded similar results, with low-carbohydrate-high-fat diet having no superior effect on FM in comparison to a normal diet [ 37 ]. However, some carbohydrate sources can be beneficial, while others are not, depending at least in part on their fiber content [ 38 ].…”

Nutrition in Menopausal Women: A Narrative Review

Among the various aspects of health promotion and lifestyle adaptation to the postmenopausal period, nutritional habits are essential because they concern all women, can be modified, and impact both longevity and quality of life. In this narrative review, we discuss the current evidence on the association between dietary patterns and clinical endpoints in postmenopausal women, such as body composition, bone mass, and risk markers for cardiovascular disease. Current evidence suggests that low-fat, plant-based diets are associated with beneficial effects on body composition, but further studies are needed to confirm these results in postmenopausal women. The Mediterranean diet pattern along with other healthy habits may help the primary prevention of bone, metabolic, and cardiovascular diseases in the postmenopausal period. It consists on the use of healthy foods that have anti-inflammatory and antioxidant properties, and is associated with a small but significant decrease in blood pressure, reduction of fat mass, and improvement in cholesterol levels. These effects remain to be evaluated over a longer period of time, with the assessment of hard outcomes such as bone fractures, diabetes, and coronary ischemia.
