Intuitive Eating for Neurodivergence

Intuitive eating is an emerging movement that prioritizes listening to your own internal cues, shedding expectations of society, and honoring your mind, body, and soul in relation to eating and nourishing our bodies. It is a health approach established by two dieticians, Evelyn Tribole and Elyse Resch, in 1995 that set out to create an alternative to toxic weight obsession, food restriction, and diet culture. Since its foundation there have been over 90 studies focused on intuitive eating and its outcomes but few have focused on the neurodivergent population.  

Intuitive eating for neurodiverse folks has many of the same core principles as classic intuitive eating, but there are a few major differences. One of the foundational pillars of intuitive eating is interoception, which is defined as the awareness of your body’s internal senses or signals. [2] A meta-analysis by Williams et al. (2023) found that autistic individuals show significantly reduced heartbeat counting performance (a proxy for interoceptive accuracy), yet paradoxically higher confidence in their interoceptive abilities. [3] Trevisan et al. (2021) documented first-hand accounts of autistic adults describing limited awareness of hunger, satiation, and thirst, which in some cases contributed to disordered eating behaviors. [4] Bayoumi et al. (2025) confirmed that autistic adults, with or without ADHD, report significantly more eating difficulties than other groups, with insistence on sameness and sensory sensitivity as key predictors. [5] In ADHD, Martin et al. (2023) demonstrated longitudinally that reduced reliance on hunger/satiety cues mediates the relationship between inattentive ADHD symptoms and both restrictive and binge-type eating. [12]

Neurodiverse people also often struggle with dichotomous thinking, or “black and white” thinking, which defines itself as a thinking style that categorizes things into two, such as, “all or nothing”, “right or wrong”, and “good or bad”. There are a few thoughts as to why dichotomous thinking is beneficial to our survival; namely that people who tend to rely on dichotomous thinking do not need to allocate many resources to make judgments, and that they are able to engage in reasoning quickly. [6] Neurodivergent folks generally struggle with a concept called “decision fatigue” more than the neurotypical population. A comprehensive narrative review by van der Plas et al. (2023) synthesized 104 studies and found that autistic individuals perform comparably to neurotypical controls on perceptual (sensory based) and reward-learning decisions (decision through trial and error, guided by a system of feedback), but differ significantly on metacognitive and value-based decision-making; tasks requiring subjective evaluation and weighing of options, which are the types of decisions most susceptible to decision fatigue. [7] Vella et al. (2018) found that autistic adults demonstrate slower decision-making and sample more information before deciding, suggesting a more deliberative but resource-intensive decision process that could theoretically accelerate fatigue.[8] This overlaps with dichotomous thinking because it means that decisions that may hold uncertainty or feel as though they require additional energy become less costly. Two studies by Suzuki & Hirai (2023) and Shi & Hirai (2024) provide the most direct evidence linking autistic traits to dichotomous thinking, mediated by intolerance of uncertainty. [9-10] Interestingly, the direct association between autistic traits and dichotomous thinking was actually negative, meaning that most decisions are made with understanding of many nuances and options, and it was only through the pathway of intolerance of uncertainty that autistic traits led to increased dichotomous thinking. Atypical sensory processing was also identified as a mediator linking autistic traits to intolerance of uncertainty. [10] In the eating domain specifically, Palascha et al. (2015) demonstrated that eating-specific dichotomous thinking (dichotomous beliefs about food and eating) mediates the association between restraint eating and weight regain. [11] 

Dichotomous thinking about food (e.g., "good" vs. "bad" foods) undermines the flexible, non-judgmental relationship with food that intuitive eating requires. Interoceptive differences in autism and ADHD create additional barriers to relying on internal hunger/satiety cues. These two major differences in neurodivergent vs neurotypical behavioral patterns means that intuitive eating needs to be modified for the neurodiverse population to be most effective. A key study that recently came out sought to answer the question of how to best modify intuitive eating for neurodiverse folks by examining intuitive eating in a neurodivergent population. Longhurst et al. (2026), published in Body Image interviewed 20 autistic/AuDHD adults in the UK and identified three overarching themes: (Re)defining intuitive eating — Participants described needing to redefine intuitive eating beyond the standard framework, which assumes reliable internal hunger/satiety cues. For autistic/AuDHD individuals, intuitive eating requires incorporating external cues (e.g., timers, routines, visual reminders) alongside internal ones, given interoceptive differences. Disruptions to intuitive eating — Barriers included sensory sensitivities affecting food choices, executive functioning difficulties interfering with meal planning, and the impact of masking/burnout on eating behaviors. Reframing and supporting intuitive eating — Participants identified facilitators such as self-compassion, accommodating sensory needs without judgment, and reframing "body-food choice congruence" to include sensory and emotional reasons for eating (not just physical hunger). [13] So how do you integrate all this into intuitive eating? Here are the key principles:

Intuitive Eating Adapted for Neurodivergent Brains

1. Use External Cues Alongside Internal Ones

• If you struggle to notice hunger or fullness, it is completely valid to use external supports:

  • Set timers or alarms to remind yourself to eat at regular intervals.

  • Use visual schedules or meal-planning apps.

  • Pair mealtimes with existing routines (e.g., eating after a morning walk).

*You do not have to rely only on internal signals. Using external structure is a legitimate and effective strategy.

2. Give Yourself Unconditional Permission to Eat

• There are no "good" or "bad" foods. Thinking in all-or-nothing terms about food (e.g., "I ate something unhealthy so the whole day is ruined" “nothing I have is right so I just won’t eat”) can lead to cycles of restriction and overeating.

• If you notice yourself categorizing foods rigidly, try gently expanding your categories rather than forcing a complete change all at once.

3. Honor Sensory Needs Without Judgment

• It is okay to prefer certain textures, temperatures, or flavors. Sensory preferences are a real part of how your brain works.

• Eating the same meals repeatedly is fine if it reduces stress and meets your nutritional needs.

• "Body-food choice congruence" for you might mean choosing foods that feel right sensorially and emotionally, not just nutritionally.

4. Reduce Decision Fatigue Around Food

• Plan meals in advance when you have the energy to do so.

• Keep a short list of "safe" meals you can default to on hard days.

• Simplify choices: instead of deciding what to eat from scratch, choose from 2–3 pre-selected options.

• Batch cook or meal prep when possible to reduce daily decisions.

5. Eat for Physical, Emotional, AND Sensory Reasons

• Eating for comfort or enjoyment is normal and healthy, not something to feel guilty about.

• Recognize that emotional eating and sensory-seeking eating are different from binge eating. Enjoying food is part of well-being.

Integrating this nuance can help modify intuitive eating so that it works better for the neurodivergent brain. Want one-on-one help incorporating these principles into your life? Set up a free 15 minute discovery call!
