There have now been a number of reviews on this topic. A recent (07/2021) narrative review paper from Wheatley et al is an excellent overview of the literature, the remaining areas of controversy, and practical recommendations.

As oestrogen/progesterone are insulin sensitizing hormones, a reduction in these hormones can increase insulin resistance which may contribute to the metabolic dysregulation and symptoms of menopause. This section includes studies that support potential benefits of a TCR approach to help manage areas of common concern during menopause, primarily as a means of reducing glycaemic variability and insulin resistance.
Insulin resistance, weight gain and cardiovascular disease
Therapeutic carbohydrate reduction is one way to combat insulin resistance, weight gain, and inflammation – risk factors for CVD. Insulin resistance also contributes to platelet dysfunction and clotting risk.
Glycaemic variability, insulin resistance and hot flashes
Sleep has a bidirectional effect on metabolic health. Poor sleep patterns, such as shift work, can increase insulin resistance and increase the risk of developing metabolic syndrome. Increasing insulin resistance via other mechanisms, like changes in hormones, can reduce melatonin (inverse relationship) and affect sleep.
For more on this, see section on sleep.
Brain glucose hypometabolism and cognitive decline
‘The peri-menopausal transition is a tipping point for female brain aging. From the metabolic perspective, the process begins with decline in glucose metabolism and increase in insulin resistance, followed by a compensatory mechanism to use fatty acids and ketone bodies as an auxiliary fuel source’ Wang et al
TCR reduces brain insulin resistance and inflammation. If carbohydrate intake is sufficiently reduced ketone bodies can provide an alternative fuel source for the brain, further supporting cognitive function.

Breast Cancer and Insulin Resistance
Multiple factors contribute to increased risk of breast cancer – the presence of insulin resistance/metabolic syndrome is known to impact risk and prognosis. For more on this, see section on cancer.
