VLCD inducing a period after not having period for a long time???


I have had very irregular periods over the last few years with my steady and fast weight gain and they stopped a few months ago.
Is it just a coincidence that my period started 5 days into my VLCD?
There hasn't been any significant weight loss...but has anyone had any menstrual changes when they suddenly changed their calorie intake?
Happened for me! I have a coil so my periods are irregular anyway but I havent had a 'proper' period in MONTHS. However halfway through day 1 I came on. Apparently it's common :)
Oestrogen is stored in fat cells. Decimating them quickly (even if loss feels small to you, is a lot of cells) releases it and can prompt menstruation. Xx
