What exactly are your eating difficulties? Are there difficulties with the amount of food or the range of foods or both? Are these long standing difficulties or more recent? Are you having any additional supplements; if so, how many, via what method and when are they given? Are the difficulties experienced across all environments: school, home, friends, relatives, restaurants?
Understand
What are the main drivers for avoidance and restrictive patterns of eating? Low interest in food? Sensory sensitivities? Concern about adverse consequences? Why might these be present? Disrupted appetite, low desire to eat due to mood, stress, concentration, over arousal? Is restriction a side effect of medication? Are any concurrent illness or conditions affecting avoidance or restrictive eating such as oral-motor difficulties? Are you a supertaster? Are your feelings of disgust or anxiety related to past negative experiences or worries picked up from others? Other difficulties such as ADHD, ASD, intellectual disabilities, family with restrictive eating difficulties?
Accept
Accepting this is how things are at present. Accepting it is okay to worry and it is likely your eating is a result of normal fear related responses. Understanding and accepting you might be responding this way at present. Understanding that this does not have to be forever and that change can be a slow process.
Challenge
Identify what needs to change and whether there is real potential for change. What needs exploring first? How might this be achieved? What are the current consequences of eating difficulties and how might this affect what is changed first?
Change
To start making changes follow this five-step model sequence. Keep a record of changes, things that you try, what works and what doesn't. Appreciate the small changes and be realistic about your expectations. Be as clear and consistent as you can, minimising confrontation as much as possible.
