Managing low weight and weight loss

Why is my child underweight?

Your child’s weight may be low or dropping due to a number of reasons, which can include:

• medications can reduce appetite
• your child may be burning off energy due to hyperactivity
• your child may have lost interest in food
• at meal times your child may become distracted. 

Your consultant or clinical nurse specialist will monitor weight, height and growth patterns. If there are concerns with your child weight a dietician can work with you to provide tailored advice for weight gain.

Why is it important that your child is a healthy weight?

Children need enough energy, protein and nutrients to grow. If your child’s weight is low or decreasing it can show that they are not receiving the correct nutrients. This can lead to deficiencies and faltering growth.

How can we increase weight?

The best way to increase calories is to offer 3 small meals and 3 snacks per day. Make every bite count by ensuring they are nutritious and energy dense. High energy, high protein foods are an easy way to increase your child’s intake without increasing portion sizes. 

Why high energy and high protein?

Energy will help to increase weight. High energy foods are usually those that contain a lot of fats and sugars. These help to put on weight. Protein allows growth and to help build muscle. Both of these nutrients are essential in increasing weight and promoting growth.

High protein foods

• dairy products
• meat 
• eggs
• beans
• nuts
• seeds
• peanut butter

High energy foods

• butter
• margarine
• cream
• full cream dairy products
• ice cream
• chocolate
• chocolate spread

By adding high energy and high protein food to meals you can increase the calories significantly, without increasing the volume of meals.  This is called food fortification.

1 heaped teaspoon = extra 75 calories

Sample meal plan:

Lunch

• Ham sandwich (add butter and cheese)

Evening meal

• Lasagne (add cheese, cream and fry meat and vegetables in oil)

Fortifying this meal can increase calories by around 1,700 Kcals. 

This meal planner is an idea of what you could work towards. You need to add in changes slowly and get your child used to the high calorie and high protein foods. 

Snack ideas

• mixed nuts
• cracker and cheese with butter
• crisps with dips
• milk dessert
• breakfast cereal
• porridge
• toast with butter or chocolate spread
• cheese scone
• full cream yogurt
• rice pudding
• custard
• cheese on toast
• croissant

Nourishing drinks 

Nourishing drinks are a great way to increase calories. These drinks are milk based. Milk is high in protein, energy and nutrients. Full cream milk is preferable. In the back of this booklet there are some nourishing drinks recipes. 

Fortified milk: 2 – 4 heaped tablespoons of milk powder can be added to 1 pint of full cream milk.  You can use this milk and add this to custard, rice pudding, cereals, porridge, mashed potato or whenever you would normally use milk. 

Top tips for meal times

• Make everything your child eats and drinks as nourishing as possible
• Don’t let your child fill up on fluids before meal times
• Take advantage of the times your child feels hungry – usually this is evening when medication can be wearing off.
• Keep ready to eat snacks available for your child to help themselves to at snack time. You could make a snack plate for them whilst they are playing. 
• Make a timetable of meal times so your child knows when they are eating next.
• Keep a food chart so your child can tick off when they have had their meal or snack. This will help busy house hold keep track of meals and snacks.
• Make meal times relaxing and try not to cause anxiety around meals. 
• Some children find it difficult concentrate at meal times. Remove distractions away from the dinner table. 
• Praise your child for eating. Don’t punish them for not eating as this can cause negative associations with food. 
• Offer two separate courses. One main meal and one dessert. 

At school

• If your child finds it difficult to eat at school as they are not hungry then provide them with a nourishing drink. 
• Go through school meal menu options on a weekly basis so they know what to expect. 
• Ask your child’s school to provide an early pass for lunch so they have more time to eat their lunch.

Make food interesting

• Take your children shopping to look at foods.
• Include your children in preparing the food. 
• Think about how you display food – make it look interesting.
• Don’t give large portions which can over face your child.
• Let children serve themselves and put food on their plate.
• Have theme nights to make food more fun. For example American Breakfasts or Mexican nights.
