When trying to lose weight, it’s natural to want to see quick results. So when the number on the scales drops rapidly, it seems like we’re on the right track.

But as with many things related to weight loss, there’s a flip side: rapid weight loss can result in a significant loss of muscle mass, as well as fat.

So how you can tell if you’re losing too much muscle and what can you do to prevent it?

Why does muscle mass matter?

Muscle is an important factor in determining our metabolic rate: how much energy we burn at rest. This is determined by how much muscle and fat we have. Muscle is more metabolically active than fat, meaning it burns more calories.

When we diet to lose weight, we create a calorie deficit, where our bodies don’t get enough energy from the food we eat to meet our energy needs. Our bodies start breaking down our fat and muscle tissue for fuel.

A decrease in calorie-burning muscle mass slows our metabolism. This quickly slows the rate at which we lose weight and impacts our ability to maintain our weight long term.

How to tell you’re losing too much muscle

Unfortunately, measuring changes in muscle mass is not easy.

The most accurate tool is an enhanced form of X-ray called a dual-energy X-ray absorptiometry (DXA) scan. The scan is primarily used in medicine and research to capture data on weight, body fat, muscle mass and bone density.

But while DEXA is becoming more readily available at weight-loss clinics and gyms, it’s not cheap.

There are also many “smart” scales available for at home use that promise to provide an accurate reading of muscle mass percentage.

However, the accuracy of these scales is questionable. Researchers found the scales tested massively over- or under-estimated fat and muscle mass.

Fortunately, there are three free but scientifically backed signs you may be losing too much muscle mass when you’re dieting.

1. You’re losing much more weight than expected each week

Losing a lot of weight rapidly is one of the early signs that your diet is too extreme and you’re losing too much muscle.

Rapid weight loss (of more than 1 kilogram per week) results in greater muscle mass loss than slow weight loss.

Slow weight loss better preserves muscle mass and often has the added benefit of greater fat mass loss.

One study compared people in the obese weight category who followed either a very low-calorie diet (500 calories per day) for five weeks or a low-calorie diet (1,250 calories per day) for 12 weeks. While both groups lost similar amounts of weight, participants following the very low-calorie diet (500 calories per day) for five weeks lost significantly more muscle mass.

2. You’re feeling tired and things feel more difficult

It sounds obvious, but feeling tired, sluggish and finding it hard to complete physical activities, such as working out or doing jobs around the house, is another strong signal you’re losing muscle.

Research shows a decrease in muscle mass may negatively impact your body’s physical performance.

3. You’re feeling moody

Mood swings and feeling anxious, stressed or depressed may also be signs you’re losing muscle mass.

Research on muscle loss due to ageing suggests low levels of muscle mass can negatively impact mental health and mood. This seems to stem from the relationship between low muscle mass and proteins called neurotrophins, which help regulate mood and feelings of wellbeing.

So how you can do to maintain muscle during weight loss?

Fortunately, there are also three actions you can take to maintain muscle mass when you’re following a calorie-restricted diet to lose weight.

1. Incorporate strength training into your exercise plan

While a broad exercise program is important to support overall weight loss, strength-building exercises are a surefire way to help prevent the loss of muscle mass. A meta-analysis of studies of older people with obesity found resistance training was able to prevent almost 100% of muscle loss from calorie restriction.

Relying on diet alone to lose weight will reduce muscle along with body fat, slowing your metabolism. So it’s essential to make sure you’ve incorporated sufficient and appropriate exercise into your weight-loss plan to hold onto your muscle mass stores.

But you don’t need to hit the gym. Exercises using body weight – such as push-ups, pull-ups, planks and air squats – are just as effective as lifting weights and using strength-building equipment.

Encouragingly, moderate-volume resistance training (three sets of ten repetitions for eight exercises) can be as effective as high-volume training (five sets of ten repetitions for eight exercises) for maintaining muscle when you’re following a calorie-restricted diet.

2. Eat more protein

Foods high in protein play an essential role in building and maintaining muscle mass, but research also shows these foods help prevent muscle loss when you’re following a calorie-restricted diet.

But this doesn’t mean just eating foods with protein. Meals need to be balanced and include a source of protein, wholegrain carb and healthy fat to meet our dietary needs. For example, eggs on wholegrain toast with avocado.

3. Slow your weight loss plan down

When we change our diet to lose weight, we take our body out of its comfort zone and trigger its survival response. It then counteracts weight loss, triggering several physiological responses to defend our body weight and “survive” starvation.

Our body’s survival mechanisms want us to regain lost weight to ensure we survive the next period of famine (dieting). Research shows that more than half of the weight lost by participants is regained within two years, and more than 80% of lost weight is regained within five years.

However, a slow and steady, stepped approach to weight loss, prevents our bodies from activating defence mechanisms to defend our weight when we try to lose weight.

Ultimately, losing weight long-term comes down to making gradual changes to your lifestyle to ensure you form habits that last a lifetime.

As a clinical psychologist, I often have clients say they are having trouble with thoughts “on a loop” in their head, which they find difficult to manage.

While rumination and overthinking are often considered the same thing, they are slightly different (though linked). Rumination is having thoughts on repeat in our minds. This can lead to overthinking – analysing those thoughts without finding solutions or solving the problem.

It’s like a vinyl record playing the same part of the song over and over. With a record, this is usually because of a scratch. Why we overthink is a little more complicated.

We’re on the lookout for threats

Our brains are hardwired to look for threats, to make a plan to address those threats and keep us safe. Those perceived threats may be based on past experiences, or may be the “what ifs” we imagine could happen in the future.

Our “what ifs” are usually negative outcomes. These are what we call “hot thoughts” – they bring up a lot of emotion (particularly sadness, worry or anger), which means we can easily get stuck on those thoughts and keep going over them.

However, because they are about things that have either already happened or might happen in the future (but are not happening now), we cannot fix the problem, so we keep going over the same thoughts.

Who overthinks?

Most people find themselves in situations at one time or another when they overthink.

Some people are more likely to ruminate. People who have had prior challenges or experienced trauma may have come to expect threats and look for them more than people who have not had adversities.

Deep thinkers, people who are prone to anxiety or low mood, and those who are sensitive or feel emotions deeply are also more likely to ruminate and overthink.

Also, when we are stressed, our emotions tend to be stronger and last longer, and our thoughts can be less accurate, which means we can get stuck on thoughts more than we would usually.

Being run down or physically unwell can also mean our thoughts are harder to tackle and manage.

Acknowledge your feelings

When thoughts go on repeat, it is helpful to use both emotion-focused and problem-focused strategies.

Being emotion-focused means figuring out how we feel about something and addressing those feelings. For example, we might feel regret, anger or sadness about something that has happened, or worry about something that might happen.

Acknowledging those emotions, using self-care techniques and accessing social support to talk about and manage your feelings will be helpful.

The second part is being problem-focused. Looking at what you would do differently (if the thoughts are about something from your past) and making a plan for dealing with future possibilities your thoughts are raising.

But it is difficult to plan for all eventualities, so this strategy has limited usefulness.

What is more helpful is to make a plan for one or two of the more likely possibilities and accept there may be things that happen you haven’t thought of.

Think about why these thoughts are showing up

Our feelings and experiences are information; it is important to ask what this information is telling you and why these thoughts are showing up now.

For example, university has just started again. Parents of high school leavers might be lying awake at night (which is when rumination and overthinking is common) worrying about their young person.

Knowing how you would respond to some more likely possibilities (such as they will need money, they might be lonely or homesick) might be helpful.

But overthinking is also a sign of a new stage in both your lives, and needing to accept less control over your child’s choices and lives, while wanting the best for them. Recognising this means you can also talk about those feelings with others.

Let the thoughts go

A useful way to manage rumination or overthinking is “change, accept, and let go”.

Challenge and change aspects of your thoughts where you can. For example, the chance that your young person will run out of money and have no food and starve (overthinking tends to lead to your brain coming up with catastrophic outcomes!) is not likely.

You could plan to check in with your child regularly about how they are coping financially and encourage them to access budgeting support from university services.

Your thoughts are just ideas. They are not necessarily true or accurate, but when we overthink and have them on repeat, they can start to feel true because they become familiar. Coming up with a more realistic thought can help stop the loop of the unhelpful thought.

Accepting your emotions and finding ways to manage those (good self-care, social support, communication with those close to you) will also be helpful. As will accepting that life inevitably involves a lack of complete control over outcomes and possibilities life may throw at us. What we do have control over is our reactions and behaviours.

Remember, you have a 100% success rate of getting through challenges up until this point. You might have wanted to do things differently (and can plan to do that) but nevertheless, you coped and got through.

So, the last part is letting go of the need to know exactly how things will turn out, and believing in your ability (and sometimes others’) to cope.

What else can you do?

A stressed out and tired brain will be more likely to overthink, leading to more stress and creating a cycle that can affect your wellbeing.

So it’s important to manage your stress levels by eating and sleeping well, moving your body, doing things you enjoy, seeing people you care about, and doing things that fuel your soul and spirit.

Distraction – with pleasurable activities and people who bring you joy – can also get your thoughts off repeat.

If you do find overthinking is affecting your life, and your levels of anxiety are rising or your mood is dropping (your sleep, appetite and enjoyment of life and people is being negatively affected), it might be time to talk to someone and get some strategies to manage.

When things become too difficult to manage yourself (or with the help of those close to you), a therapist can provide tools that have been proven to be helpful. Some helpful tools to manage worry and your thoughts can also be found here.

When you find yourself overthinking, think about why you are having “hot thoughts”, acknowledge your feelings and do some future-focused problem solving. But also accept life can be unpredictable and focus on having faith in your ability to cope.
