Weight goes up more easily, energy becomes less steady, and fat accumulates around the belly in a way that used to be much easier to control.<\/span><\/p><p><span style=\"font-weight: 400;\">This is not a lack of willpower or discipline. Most often it is linked to the natural hormonal and metabolic changes that take place in the body during perimenopause.<\/span><\/p><p><span style=\"font-weight: 400;\">In this article we look at why metabolism slows down after 40, how hormones affect weight and which habits can help you feel well.<\/span><\/p><p> <\/p><h2><span style=\"font-weight: 400;\">How do hormones affect metabolism?<\/span><\/h2><p><span style=\"font-weight: 400;\">As perimenopause approaches \u2013 usually between the ages of 40 and 50 \u2013 the production of oestrogens decreases.

Basal metabolism slows down<\/span><\/h3><p><span style=\"font-weight: 400;\">With age the body needs less energy even at rest.<\/span><\/p><h3><span style=\"font-weight: 400;\">2. Muscle mass decreases<\/span><\/h3><p><span style=\"font-weight: 400;\">From around the age of 35 muscle mass naturally begins to decline. Because muscle uses more energy than fat tissue, when there is less of it the body burns fewer calories.<\/span><\/p><h3><span style=\"font-weight: 400;\">3. The hormonal balance changes<\/span><\/h3><p><span style=\"font-weight: 400;\">Hormonal changes encourage fat to accumulate around the belly, especially when stress is high or sleep is short.<\/span><\/p><p> <\/p><h2><span style=\"font-weight: 400;\">Glucose fluctuations and a lack of energy<\/span><\/h2><p><span style=\"font-weight: 400;\">After 40 the way the body responds to carbohydrates often changes.<\/span><\/p><p><span style=\"font-weight: 400;\">When blood glucose levels fluctuate:<\/span><\/p><ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">hunger is felt more often;<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">cravings for sweets become stronger;<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">energy becomes unstable;<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">body weight is harder to control.<\/span><\/li><\/ul><p><span style=\"font-weight: 400;\">Constantly raised insulin sends the body a signal to store energy rather than burn it.
