Home » Signs that you are over-exercising and what to do
The notion that “exercise is good for you – do more!” has been hammered into our heads from a young age and to what end? You may think the more the better, but not when it comes at the expense of your health.
Some of us may think that having no period is a blessing – it means no cramps, less bloating, no period diarrhoea , and no (okay, maybe less) mood swings. But when you begin to understand the health consequences of losing your period, you may think again.
The combination of overtraining and under fuelling ultimately leads to burnout and potentially a whole host of serious health consequences often indicated by a loss of period (but not limited to) that will be presented in this blog article.
Let us also be clear, however, that whether you have a uterus or not – under fuelling has long-term consequences and can affect anyone that is pushing themselves beyond their limit. That is, whether you are training to stand on the Olympic podium or an amateur athlete – the risk equally presents itself.
The term ‘Relative Energy Deficiency in Sport’ (RED-S) was a condition formerly known as the ‘Female Athlete Triad’. In short, this condition affects women and men, and it can be characterised by energy deficiency relative to the balance one has between dietary energy intake and energy expenditure; required for health and activities of daily living, growth and sporting activities leading to multi-system dysfunction. (1)
Our bodies need a certain amount of energy to function and stay alive. On top of that, if we do physical activity or sport, we require even more energy. Therefore, if you do not put in enough energy for the amount of work your body is doing, it can result in RED-S.
The consequence of that disequilibrium is that when your body does not have enough energy to support its needs, it will prioritise organs and functions vital for health and life, whilst other systems that are not deemed as ‘essential’ will start to turn off, such as reproductive health.
It is like if your phone battery reaches 30%, it may go into battery saving mode, and start putting different apps to sleep in the background to save energy.
For females, changes in menstruation are a clear sign that there is a problem. Whether their period becomes, lighter, erratic or stops completely (called amenorrhea). For males it can be harder to identify the symptoms. To learn more tips on how to restore your period read this article.
Symptoms can include anything from a drop in libido, a drop in serotonin levels, changes in bowel habit (often misdiagnosed as symptoms of IBS), finding yourself more prone to injury, lowered immune function and not being able to train and perform at the level you once could.
These consequences can have serious implications for many bodily systems aside from reproductive health resulting in short-term and long-term impact on health and performance. See figure 1 and 2 for visual diagram of potential health and performance consequences.

Dietitian Renee McGregor describes an important difference in voluntary vs involuntary RED-S.
Involuntary RED-S is unintentional under-fuelling. The athlete is not intentionally restricting intake, but instead is struggling to fuel adequately for a variety of reasons such as food availability, lack of nutritional education and support, life demands, stress and others.
Voluntary RED-S is conscious restriction of energy intake and/or overtraining. This typically has a psychological component leading to anxiety, body image concerns, disordered eating, and for some individuals a clinically diagnosable eating disorder.
If you suspect you have RED-S, it is important to first consult your GP, who may then involve medical, dietetic and mental health support depending on your individual situation. A multi-disciplinary approach is recommended in the treatment for RED-S, particularly if there is any concern about disordered eating. (2, 4) Treatment should focus on reversing the underlying cause: low energy availability.
Correcting energy balance is an essential treatment of RED-S to address the fundamental cause of low energy availability. In adolescents and women with functional hypothalamic amenorrhea, correcting the energy imbalance is necessary to improve hypothalamic–pituitary–ovarian (HPO) axis function. In order to do this, behaviour change is needed to increase caloric consumption, improve nutritional status (such as vitamin D and calcium), and potentially decrease exercise activity with the support of a registered dietitian. Weight gain may be necessary as part of this process. (5)
Carbohydrates are needed to fuel training and the amount of glycogen stored in muscles has a direct impact on performance. Therefore, adequate carbohydrate availability around training is essential, particularly for bone health. 6, 7 For most athletes, high-carbohydrate intakes are required. Carbohydrates consumed before exercise results in improved performance. 7 Read an article here where two dietitians explain what to eat before and after a workout.
Cognitive behavioural therapy has been found to be helpful in treatment of RED-S, both to help cope with daily stresses and may be supportive of the behaviour change required to regain energy balance. (1, 5, 8, 9).
Studies have shown that CBT results in higher rate of return of ovulatory function for women with functional hypothalamic amenorrhea. (6, 8, 9) Therapy can also be helpful if dealing with perfectionism and/or body dissatisfaction which is often seen in athletes, particularly female athletes, and can exacerbate risk of disordered eating. (10)
For many recovery may mean reducing the overall intensity of their workouts or training sessions – especially endurance training – while for others it may mean stopping training all together. The evidence demonstrates that a structured re-introduction to training is helpful and should first start with resistance training/ body weight strength and conditioning. Meanwhile this is when an appropriate fuelling routine can be established to ensure adequate nutrition. Endurance training should be eased into and last but not least, high intensity exercise is ideally the last type of activity to be re-introduced as it requires the greatest energy demands.
