Why diabetics lose weight abruptly? And how can we overcome it?

Diabetics cut-off carbohydrates to a large extent. It’s liable. But as diabetics are always in low energy mode due to minimal carbohydrates reserves and cause they effort physically more to overcome diabetes with strict diet they slowly start losing their fat reserves. After depletion of carbohydrates reserves their body will also lose carbohydrates in form of glycogen storage from their muscles mass. And after cut-off of fats reserves they will start losing fats content from muscles mass as well. This is why diabetics lose muscles facia first, then lose muscles fibers and at last lose muscles mass that is the reason why they lose their weight abruptly. 

Regarding how to overcome it, diabetics should keep their protein intake higher and fat intake a little bit more than normal. Cause fat content is a bit more and even body is making more physical effort to overcome diabetes body mechanics tends to retain loss of muscles mass or weight as fats continues supplying energy even after starvation or fatigue. And since protein content is high it will help restoration of muscles mass or slows down the process of muscles loss. 

So, in conclusion, up taking high protein and a bit more fats will check abrupt loss of muscles mass or weight in diabetics.
