If you weigh the same and your muscles are shrinking, then you are adding fat
Since the lockdown began, I have had to stop doing my more intense strength exercises at the gym - I used to go three times weekly. Like you, I've read that our muscles "turn to fat" when we stop exercising.
That's a scary thought, especially after 20 years of progressively building my muscular strength and endurance.
There's good news and bad news. The good news is that our muscles don't turn to fat - that's not even remotely true. The bad news is that our bodies will accumulate more fat if we continue to eat the same amount as we did with more muscle.
More gains in less time with this single-move whole-body workout
I've been training now for 20+ years, since I was diagnosed with Type 2 diabetes at 50.
I take it seriously.
Diabetes doesn't just kill you; it does it cruelly - slowly destroying your circulation. Amputations, kidney failure, blindness and dementia result from your capillaries slowly clagging up with excess sugar.
That's why I take exercise seriously as a means of managing my diabetes.
Since I was diagnosed at 50 with Type 2 diabetes I've been learning how to do bone-building fitness training which lowers my age. You can too. It's your choice. Walter
