Advice needed for stopped menstrual cycle

I would say you should seek the help of a medical professional to make sure everything is alright with your system. Good luck!

Just upping my calories to a more sensible level helped me. Most of your gain was probably just replenishing your body's stores of what it needed. Try aiming for a smaller deficit and lose weight slowly.

if your period has stopped due to not eating enough or losing too much weight then you need to eat more and if necessary gain weight.

loss of period means your female hormone levels are very low, which has a number of bad effects in the body, including decreased bone density and a risk of osteoporosis

The healthy body fat percentage range for women is 18-28%, and while female bodybuilders may drop their body fat percentage as low as 13% for contests, they eat more to bring it back to around 18% off season for health reasons. You also should have a decent amount of lean body mass for your frame size, and most people who are underweight have too little lean mass rather than too little fat. If your body fat percentage is in the healthy range but you've got no period due to being underweight you need to rebuild your lean mass.

Even if your body composition is healthy, loss of your period can come just from eating too little, so if that's the case then eat more. You don't need to eat very little to lose fat. Aim for slow fat loss with a sensible deficit, and do strength training and eat plenty of protein to keep your lean mass.

All the research papers I saw on overtraining in women and loss of period, overtraining wasn't the problem, undereating was, and the same women could resume the same amount of training and get their period back by eating more. Overtraining is a real thing, just that most cases of overtraining are actually caused by undereating.

a womans cycle is due to body fat and if you have to low bodyfat your period stops. If you are not an athlete who trains hard for their profession it is a sign you are not healthy...you need more fat on your body and it needs to stay there in order for you to have your cycle.

And just so you know after your cycle stops the next step is hair falling out, If left untreated, long-term complications include increased risk of broken bones and premature ageing. Along with a whole host of other things that can and will go wrong such as depression, bloating, constipation, fine hair growth all over the body etc...it's not pretty.

I suspect you are not a professional athlete so I suggest you seek some professional help for the signs of an eating disorder.

even in professional athletes, loss of period is a sign that they need to eat more. While this is sometimes accepted as an inevitable cause of doing a lot of exercise, in fact it's due to undereating, but in the case of athletes, they may be eating a lot of food, but still not enough to maintain their activity levels.

I researched this topic for my undergrad study at uni, and the overwhelming majority of journal articles I read on it said the same thing... it's not due to overtraining, it's due to undereating and female athletes who increased their food intake got their period back without reducing the amount of training they were doing.
