How to Manage Fullness and Poor Appetite

Written by Rhiannon Stone, Registered Dietitian

tips to overcome poor appetite

Appetite and hunger are words that are often thrown around in the social media world as things we ‘must control' in order to lead a healthy lifestyle. We are force fed tips and tricks to curb our hunger and control our appetite. But what about those people who struggle with appetite and hunger? And struggle to gain weight?

What's the difference between appetite and hunger?

Appetite is defined as a natural desire to satisfy a bodily need, especially for food. Physical hunger is defined as the body’s response to a lack of food resulting in a desire to eat. Together, appetite and hunger remind us to supply our body with the energy it needs to survive. But, when these signals are reduced, we can be left feeling fatigued, weak and unable to complete our day-to-day activities.

What causes a reduced appetite?

Reduced appetite can be caused by a range of factors including but not limited to:

  • Being underweight

  • Engaging in disordered eating or under-eating

  • Medical conditions or treatment

  • Medications

  • Anxiety and/or depression

  • Stress

  • Hormonal changes

  • Gastrointestinal upset such as constipation and/or diarrhoea

Are there different types of hunger?

To make things more interesting, hunger can be divided into different types, all initiating unique emotional and physical reactions. These include:

  • Physical/Stomach Hunger: We all know that dull gurgle in our stomach that can fire away prior to a meal time, or you might experience nausea, a headache, stomach pain, feel dizzy or shaky. These are the body’s physical responses to notify us it requires refuelling.

  • Mouth Hunger: Or cravings, is the response we have when we crave the pleasure of food, rather than to eat for fuel. Cravings can also be a way for our body to tell us it needs a quick source of energy if we are under-eating which is a primitive response to famine.

  • Heart/Head Hunger: This type of hunger is a response to our emotions and how we’re feeling mentally rather than physically. Sometimes called emotional hunger, this could be eating due to boredom, stress, anxiety or sadness. It could also be a learned behaviour such as avoiding or choosing foods based on an event or something we have seen in the media.

Although the varying types of hunger and the influences on reduced appetite may affect our desire to consume food, we need to keep in mind that food provides our bodies with the nutrition to maintain weight and keep us energised and strong. Think of food like the fuel we put in our car. If there is no fuel, there is nothing powering us to continue through our day!

We take a deep dive into the different types of hunger and emotional eating in our blog post, Why Do I Feel Hungry?

How can I manage to eat more when I don't have an appetite?

  • Have small and frequent meals and snacks rather than large ones. Just the sight of a large meal can sometimes be completely overwhelming and off-putting. Rather than attempting to eat large meals, try eating 6-8 small meals/snacks during the day.

  • Schedule your meals & snacks, don’t wait for hunger cues. Whether it is setting an alarm on your phone or penciling it into your daily planner, designate specific times to remind yourself to eat throughout the day. Aim to eat something every 2-3 waking hours. Sometimes you might need to eat even when you aren’t hungry!

  • Make every mouthful count. Following a high energy and high protein diet will ensure that you maximise the energy that your body is receiving.

Tips to make each mouthful more nourishing


You can add more energy to your food by using extra fats and oils both in cooking and drizzled on after, using nut butters, olive oil, full fat dairy, avocado, cream and spreads such as jam and Nutella.


Adding high protein foods like meat, fish, chicken, eggs, dairy/alternatives (cheese, milk, yoghurt), beans/legumes, nuts, seeds and tofu/ tempeh to every meal and snack.

Having adequate energy and protein is crucial to maintaining weight and strength, aim to consume them first from your plate before becoming too full. Here are some tips on how to make your meals and snacks higher in energy and protein, you can use our recipe hub for inspiration on meals and snacks to adapt:

High Protein Milk Recipe: for every 1 cup (250ml) of milk, add 1-2 heaped tablespoons of milk powder (full cream or skim) to create a high protein and higher energy milk. You can use this on cereal, for cooking, in desserts or wherever you would normally use milk. You can also make up 1L by adding 4-8 heaped tablespoons and keeping this in the fridge just like you would normal milk

  • Plan ahead and meal prep. Have your favourite pre-prepared snacks and meals ready. Good options include crackers and cheese/dip, frozen meals, soups, pre-made smoothies or high energy drinks, yoghurt, nuts and dairy desserts. This can also reduce anxiety about knowing what to eat and when.

  • Enjoy meals with family and friends. Eating socially in a relaxed environment can often make the food seem more appealing whilst encouraging you to eat more regularly.

  • Take notice of your symptoms. If digestive concerns such as bloating, pain, reflux, constipation or diarrhoea are contributing to fullness let your GP or Dietitian know so that they can help.

It is common to experience some digestive concerns, especially if you were undereating or trying to gain weight as your gut can be weak. Try using distraction after meals like reading, speaking to a loved one, painting, crossword or journaling. A hot water bottle, cup of tea or gentle walk after a meal can also help.

Need support to manage fullness or poor appetite?

If these initial strategies are not successful and weight loss or reduced appetite continues, high energy drinks or Oral Nutrition Supplements (ONS) can be considered. Typically, ONS are ready-made protein and energy-packed products that assist in achieving our daily nutrition requirements. As well as this, many include essential vitamins and minerals that may not be consumed whilst our appetite is poor. There are a wide range of supplement styles including juices, yoghurts, milks, puddings and powders. If ONS is something you would like to consider, reach out to a Dietitian who can discuss the best treatment for you!
