Why do some people lose more muscle mass than others?
Ageing means a decrease in the production of anabolic hormones (the hormones that promote the constitution of organic tissue). It's sad, but that's how it is.
What you should remember, though, is that this decrease has two causes. And two causes that are possible to affect:
- a sedentary lifestyle. There's no mystery here: a lack of physical activity will lead to muscle loss. So this can be remedied. Among the recommended sports, you can find weight training (not reserved for 20-year-old bodybuilders). Of course, activity should be adapted... which is ultimately true for everyone, at any age. To fight a sedentary lifestyle, you can also change some of your habits (thinking, for instance, about maybe using your bike for your trip, instead of spontaneously reaching for the car keys). Also, gardening, playing with grandchildren/nephews/nieces... or even petanque counts!
- protein deficiency: muscle is made of 20% protein. And it stores half of all proteins present in the body! No matter the origin of the proteins (animal or plant), there is just one principle to remember: no low-calorie diets for seniors.
Vitamin D deficiency can also play a role in muscle loss (muscle cells are vitamin D receptors).
