Don’t be confused – Intuitive Eating is NOT the “hunger / fullness” diet. And as the previous post mentioned, it’s also not the f*** it diet. Intuitive Eating is about learning to recognize how your body and mind communicate with you and learning how to honor their unique needs. 

But for many, we have to start by re-connecting to our body’s signals. And hunger / fullness are some of the first signals to learn. 

Let’s start off with a little eating 101. When we eat, we typically eat for 2 reasons

1. Be full
2. Be satisfied

Do you know the difference? 

Don’t worry. Most people don’t. 

Fullness literally refers to volume. Think of your stomach like a bag. When you eat, the “bag” that is your stomach fills. Nerve endings around the stomach signal distention and fullness to the brain.

However, just because the bag is full, doesn’t mean have what you want and need. Therefore, you won’t feel like you’re done eating. 

Satisfaction refers to the feeling that you like you’ve consumed what you need, and you’re done eating. 

Our body is always monitoring for our nutrient status – working to understand our overall energy status, as well as the status of each unique energy source (glucose, amino acids, lipids). If the overall status or one of the accounts is “off,” it will keep the desire for food on.

Again think about it like a plastic bag. Pretend you’re going clothes shopping and are only able to buy whatever fits in the bag. You could buy a bunch of small, items (eg, socks, underwear, jewelry) and maximize the space of that bag, but that doesn’t mean you’re satisfied with your ability to clothe the whole body (eg, you might really need a winter coat, jeans, a sweater). Additionally, if you’re stuck shopping at a place that doesn’t fit your style, you might fill the bag but not want to wear anything in it.

The point is that you have to take stock of what you need and what fits your style AND what fits into the bag. 

Hunger is a tricky concept. We can be physically and/or emotionally hungry. For the sake of simplicity, I’m going to talk about physical hunger this time. 

Physical hunger is defined by the dictionary as: 

“A feeling of discomfort or weakness caused by lack of food, coupled with the desire to eat.” 
OR
” A severe lack of food.”

Hunger can refer to an empty stomach and/or the symptoms associated with lack of food such as a drop in blood sugar. There is a physiology to the sensation of hunger, and for that I can’t believe I’m referring you to Wikipedia.

In essence, our bodies need fuel regularly. The longer bodies go without proper fuel, the more hunger cues increase and intensity. Those cues can be severe (eg, dizzy, fainting, headache, nausea) or more mild (eg, growling tummy, desiring food). 

However, it’s possible to ignore our hunger signals. If we’re distracted from our physical body (eg, busy at work, running errands, preoccupied with stress, afraid to eat), we can miss the cues. Suddenly we pause, catch the smell of the local bakery and we’re RAVENOUS. Hunger doesn’t go from 0 to 100 in a matter of minutes. These cues gradually increase. It’s like the gas gauge in the car – it’s not full then suddenly running on fumes. We were just busy watching the road and missed the gradual increase in signals. 

It’s also possible to lose the signal of hunger cues over time. If you’ve habitually skipped meals, hunger cues are no longer recognized. That doesn’t mean the body isn’t in need of food. Rather, it has adapted to ignore the cue. 

Again think about it like the gas light in your car. If you never completely fill up the tank so the light is always on, that light is going to burn out from overuse. Just because the light is gone, doesn’t mean the car doesn’t need fuel. 

And there there’s “Hungry” : “my stomach is empty and I’m thinking about food.”

For many, this isn’t a psychologically comfortable place to be, but it’s bearable. Once you are in this place, it’s time to eat! 

As I mentioned earlier, fullness literally refers to volume. If you imagine that you’re stomach is a bag / balloon, most people eat until that bag is some level of full. How full they fill it depend on how hungry they were to begin with and their current emotional state. 

What’s tricky is many things can drive us to eat BEYOND that feeling of being comfortably full. 

• Skipped meals – going too long without eating (or allowing yourself to get extremely hungry) can result in hormonal changes. Ghrelin for example, can reduce the signal of fullness. It’s triggered by going long durations without eating
• Habit – snacking while cooking, grazing while working / studying are both examples of instances someone may eat when they’re not hungry. But then they may feel they need to eat when it’s dinner time – whether to be social or because it’s “time to eat”
• Food deprivation – telling yourself that you can’t eat, trying to reduce calories, or making certain foods off limits increases our desire for food. This drive for pleasure causes us to continue eating beyond physical fullness

Satisfaction can have 2 components. It can be chemical (eg, adequate carb, protein, fat) and it can also be experiential. Aspects like taste, texture, temperature, flavor, and social / cultural relevance are considerations when determining whether or not we feel like we’ve had what we need. 

For example, if you’re at a birthday party and everyone is eating cake, but you opt for fruit. It may be difficult to feel satisfied because part of what that experience means to you is to connect with others around food. Namely – cake. 

Another example, consider the case of vegetables in winter vs summer. In the summer, I love salads – they’re crisp and refreshing. Perfect for a hot day. But in winter they’re often the last thing on my list. I can force myself to eat a salad, but I’m often left looking for something else. That doesn’t mean I stopped liking vegetables in the winter. What it means is that I prefer something hot. So I can experiment with soups, stews, roasted, sautéed, baked, and boiled vegetables to see what works for me. 

Yet another example, if you’re eating to avoid feeling difficult emotions, it can be challenging to find the “right” food to satisfy you. Because it’s not about the food – it’s about escape. You may end up “taste testing” to try to find something only to feel full, but not satisfied.  

Deciphering “what you want” can be one of the most challenging aspects about eating. Especially if you are struggling with internal / external judgments about what you “should” be eating. When those judgments creep in, you become afraid to allow yourself to eat what it really takes to make you feel like you had what you wanted.
