We all want to eat healthily, especially as we reset our health goals at the start of a new year. But sometimes these plans are sabotaged by powerful cravings for sweet, salty or carb-heavy foods.

So why do you crave these foods when you’re trying to improve your diet or lose weight? And what can you do about it?

There are many reasons for craving specific foods, but let’s focus on four common ones:

1. Blood sugar crashes

Sugar is a key energy source for all animals, and its taste is one of the most basic sensory experiences. Even without specific sweet taste receptors on the tongue, a strong preference for sugar can develop, indicating a mechanism beyond taste alone.

Neurons responding to sugar are activated when sugar is delivered to the gut. This can increase appetite and make you want to consume more. Giving into cravings also drives an appetite for more sugar.

In the long term, research suggests a high-sugar diet can affect mood, digestion and inflammation in the gut.

While there’s a lot of variation between individuals, regularly eating sugary and high-carb foods can lead to rapid spikes and crashes in blood sugar levels. When your blood sugar drops, your body can respond by craving quick sources of energy, often in the form of sugar and carbs because these deliver the fastest, most easily accessible form of energy.

2. Drops in dopamine and serotonin

Certain neurotransmitters, such as dopamine, are involved in the reward and pleasure centres of the brain. Eating sugary and carb-rich foods can trigger the release of dopamine, creating a pleasurable experience and reinforcing the craving.

Serotonin, the feel-good hormone, suppresses appetite. Natural changes in serotonin can influence daily fluctuations in mood, energy levels and attention. It’s also associated with eating more carb-rich snacks in the afternoon.

Low carb diets may reduce serotonin and lower mood. However, a recent systematic review suggests little association between these diets and risk for anxiety and depression.

Compared to men, women tend to crave more carb rich foods. Feeling irritable, tired, depressed or experiencing carb cravings are part of premenstrual symptoms and could be linked to reduced serotonin levels.

3. Loss of fluids and drops in blood sugar and salt

Sometimes our bodies crave the things they’re missing, such as hydration or even salt. A low-carb diet, for example, depletes insulin levels, decreasing sodium and water retention.

Very low-carb diets, like ketogenic diets, induce “ketosis”, a metabolic state where the body switches to using fat as its primary energy source, moving away from the usual dependence on carbohydrates.

Ketosis is often associated with increased urine production, further contributing to potential fluid loss, electrolyte imbalances and salt cravings.

4. High levels of stress or emotional turmoil

Stress, boredom and emotional turmoil can lead to cravings for comfort foods. This is because stress-related hormones can impact our appetite, satiety (feeling full) and food preferences.

The stress hormone cortisol, in particular, can drive cravings for sweet comfort foods.

A 2001 study of 59 premenopausal women subjected to stress revealed that the stress led to higher calorie consumption.

A more recent study found chronic stress, when paired with high-calorie diet, increases food intake and a preference for sweet foods. This shows the importance of a healthy diet during stress to prevent weight gain.

What can you do about cravings?

Here are four tips to curb cravings:

1) don’t cut out whole food groups. Aim for a well-balanced diet and make sure you include:

• sufficient protein in your meals to help you feel full and reduce the urge to snack on sugary and carb-rich foods. Older adults should aim for 20–40g protein per meal with a particular focus on breakfast and lunch and an overall daily protein intake of at least 0.8g per kg of body weight for muscle health
• fibre-rich foods, such as vegetables and whole grains. These make you feel full and stabilise your blood sugar levels. Examples include broccoli, quinoa, brown rice, oats, beans, lentils and bran cereals. Substitute refined carbs high in sugar like processed snack bars, soft drink or baked goods for more complex ones like whole grain bread or wholewheat muffins, or nut and seed bars or energy bites made with chia seeds and oats

2) manage your stress levels. Practise stress-reduction techniques like meditation, deep breathing, or yoga to manage emotional triggers for cravings. Practising mindful eating, by eating slowly and tuning into bodily sensations, can also reduce daily calorie intake and curb cravings and stress-driven eating

3) get enough sleep. Aim for seven to eight hours of quality sleep per night, with a minimum of seven hours. Lack of sleep can disrupt hormones that regulate hunger and cravings

4) control your portions. If you decide to indulge in a treat, control your portion size to avoid overindulging.

Overcoming cravings for sugar, salt and carbs when trying to eat healthily or lose weight is undoubtedly a formidable challenge. Remember, it’s a journey, and setbacks may occur. Be patient with yourself – your success is not defined by occasional cravings but by your ability to manage and overcome them.

Some children show signs of perfectionism from early on. Young children might become frustrated and rip up their drawing if it’s not quite right. Older children might avoid or refuse to do homework because they’re afraid to make a mistake.

Perfectionism can lead to children feeling overwhelmed, angry and frustrated, or sad and withdrawn.

And yet perfectionism isn’t considered all bad in our society. Being called a “perfectionist” can be a compliment – code for being a great worker or student, someone who strives to do their best and makes sure all jobs are done well.

These seemingly polarised views reflect the complex nature of perfectionism.

What is perfectionism?

Researchers often separate perfectionism into two parts:

1. perfectionistic strivings: being determined to meet goals and achieve highly
2. perfectionistic concerns: worry about being able to meet high standards, and self-criticism about performance.

While perfectionistic strivings can be positive and lead to high achievement, perfectionistic concerns can lead to a higher chance of children developing eating disorders or anxiety and depression, and having lower academic achievement.

Children and adolescents may experience perfectionism in relation to school work, sport, performance in art or music, or in relation to their own body.

Signs of perfectionistic concerns in children and adolescents may include:

• children being highly critical of themselves
• their reactions to mistakes seeming to be an overreaction
• intense preoccupation and worry over their standards and goals and/or procrastination
• significant change in performance, for example, lower academic results
• irritability and negative emotions, stress and feelings of worthlessness
• social problems with peers and friends, such as bullying and alienating themselves from peers.

A range of genetic, biological and environmental factors influence perfectionism in children. And as a parent, our role is important. While research evidence suggests we can’t successfully increase positive perfectionistic strivings in our children, harsh or controlling parenting can increase negative perfectionistic concerns in children.

Parents who are perfectionistic themselves can also model this to their children.

So, how can we walk the line between supporting our child’s interests and helping them to achieve their potential, without pressuring them and increasing the risk of negative outcomes?

Give them space to grow

A great metaphor is the gardener versus the carpenter described by psychology professor Alison Gopnik.

Instead of trying to build and shape our children by controlling them and their environment (like a carpenter), parents can embrace the spirit of the gardener – providing lots of space for children to grow in their own direction, and nourishing them with love, respect and trust.

We can’t control who they become, so it’s better to sit back, enjoy the ride, and look forward to watching the person they grow into.

However, there is still plenty we can do as parents if our child is showing signs of perfectionism. We can role model to our children how to set realistic goals and be flexible when things change or go wrong, help our children manage stress and negative emotions, and create healthy balance in our family daily routine.

Set realistic goals

People with perfectionistic tendencies will often set unattainable goals. We can support the development of flexibility and realistic goal setting by asking curious questions, for example, “what would you need to do to get one small step closer to this goal?” Identifying upper and lower limits for goals is also helpful.

If your child is fixed on a high score at school, for example, set that as the “upper limit” and then support them to identify a “lower limit” they would find acceptable, even if they are less happy with the outcome.

This strategy may take time and practice to widen the gap between the two, but is useful to create flexibility over time.

If a goal is performance-based and the outcome cannot be guaranteed (for example, a sporting competition), encourage your child to set a personal goal they have more control over.

We can also have conversations about perfectionism from early on, and explain that everyone makes mistakes. In fact, it’s great to model this to our children – talking about our own mistakes and feelings, to show them that we ourselves are not perfect.

Talk aloud practices can help children to see that we “walk the walk”. For example, if you burn dinner you could reflect:

I’m disappointed because I put time and effort into that and it didn’t turn out as I expected. But we all make mistakes. I don’t get things right every time.

Manage stress and negative emotions

Some children and adolescents have a natural tendency towards perfectionism. Rather than trying to control their behaviour, we can provide gentle, loving support.

When our child or adolescent becomes frustrated, angry, sad or overwhelmed, we support them best by helping them to name, express and validate all of their emotions.

Parents may fear that acknowledging their child’s negative emotions will make the emotions worse, but the opposite is true.

Creating healthy balance

The building blocks of healthy child development are strong loving family relationships, good nutrition, creative play and plenty of physical activity, sleep and rest.

Perfectionism is associated with rigidity, and thinking that there is only one correct way to succeed. We can instead encourage flexibility and creativity in children.

Children’s brains grow through play. There is strong research evidence showing that creative, child-led play is associated with higher emotion regulation skills, and a range of cognitive skills, including problem-solving, memory, planning, flexibility and decision-making.

Play isn’t just for young children either – there’s evidence that explorative, creative play of any kind also benefits adolescents and adults.

There is also evidence that getting active outdoors in nature can promote children’s coping skills, emotion regulation and cognitive development.

Made from fermented apples and naturally high in acetic acid, apple cider vinegar has been popular in recent years for its purported health benefits – from antibacterial properties to antioxidant effects and potential for helping manage blood sugars.

Its origins as a health tonic stretch much further back. Hippocrates used it to treat wounds, fever and skin sores.

An experimental study, released today, looks into whether apple cider vinegar could be effective for weight loss, reduce blood glucose levels and reduce blood lipids (cholesterol and triglycerides).

The results suggest it could reduce all three – but it might not be as simple as downing an apple cider vinegar drink a day.

What did they do?

A group of scientists in Lebanon did a double-blinded, randomised, clinical trial in a group of overweight and obese young people aged from 12–25 years.

Researchers randomly placed 30 participants in one of four groups. The participants were instructed to consume either 5, 10 or 15ml of apple cider vinegar diluted into 250ml of water each morning before they ate anything for 12 weeks. A control group consumed an inactive drink (a placebo) made (from lactic acid added to water) to look and taste the same.

Typically this sort of study provides high quality evidence as it can show cause and effect – that is the intervention (apple cider vinegar in this case) leads to a certain outcome. The study was also double-blinded, which means neither the participants or the scientists involved with collecting the data knew who was in which group.

So, what did they find?

After a period of three months apple cider vinegar consumption was linked with significant falls in body weight and body mass index (BMI). On average, those who drank apple cider vinegar during that period lost 6–8kg in weight and reduced their BMI by 2.7–3 points, depending on the dose. They also showed significant decreases in the waist and hip circumference.

The authors also report significant decreases in levels of blood glucose, triglycerides, and cholesterol in the apple cider groups. This finding echoes previous studies. The placebo group, who were given water with lactic acid, had much smaller decreases in weight and BMI. There were also no significant decreases in blood glucose and blood lipids.

From animal studies, it is thought the acetic acid in apple cider vinegar may affect the expression of genes involved in burning fats for energy. The new study did not explore whether this mechanism was involved in any weight loss.

Is this good news?

While the study appears promising, there are also reasons for caution.

Firstly, study participants were aged from 12 to 25, so we can’t say whether the results could apply to everyone.

The statistical methods used in the study don’t allow us to confidently say the same amount of weight loss would occur again if the study was done again.

And while the researchers kept records of the participants’ diet and exercise during the study, these were not published in the paper. This makes it difficult to determine if diet or exercise may have had an impact. We don’t know whether participants changed the amount they ate or the types of food they ate, or whether they changed their exercise levels.

The study used a placebo which they tried to make identical in appearance and taste to the active treatment. But people may still be able to determine differences. Researchers may ask participants at the end of a study to guess which group they were in to test the integrity of the placebo. Unfortunately this was not done in this study, so we can’t be certain if the participants knew or not.

Finally, the authors do not report whether anyone dropped out of the study. This could be important and influence results if people who did not lose weight quit due to lack of motivation.

Any other concerns?

Apple cider vinegar is acidic and there are concerns it may erode tooth enamel. This can be a problem with any acidic beverages, including fizzy drinks, lemon water and orange juice.

To minimise the risk of acid erosion some dentists recommend the following after drinking acidic drinks:

• rinsing out your mouth with tap water afterwards
• chewing sugar-free gum afterwards to stimulate saliva production
• avoiding brushing your teeth immediately after drinking because it might damage the teeth’s softened top layer
• drink with a straw to minimise contact with the teeth.

Down the hatch?

This study provides us with some evidence of a link between apple cider vinegar and weight loss. But before health professionals can recommend this as a weight loss strategy we need bigger and better conducted studies across a wider age range.

Such research would need to be done alongside a controlled background diet and exercise across all the participants. This would provide more robust evidence that apple cider vinegar could be a useful aid for weight loss.

Still, if you don’t mind the taste of apple cider vinegar then you could try drinking some for weight loss, alongside a healthy balanced and varied dietary intake. This study does not suggest people can eat whatever they like and drink apple cider vinegar as a way to control weight.
