How satiety and stomach hormones play a factor
Hormones associated with appetite suppression.
Leptin helps to decrease appetite. The more body fat you have the higher amounts of leptin you make. Leptin has been shown to be produced mostly by fat tissue When leptin is released from your body fat into the blood it is believed that leptin decreases NYP production. NYP is a potent stimulant for the signaling food intake is needed. Leptin elicits signals to the brain that change energy expenditure (moving) and energy intake(eating) . This constant influx and high levels of leptin creates a similar effect as to high levels of dopamine over a long duration. It lessens leptin receptivity. People who have high levels over long periods obtain a resistance or tolerance to the hormone. Keeping them in a state of hunger. If the duration to these levels of leptin are long enough, it can eventually no longer signal to the brain and contribute to overeating.
Leptin in the long term acts to reduce food intake and to cause a decrease in body fat.
Peptide YY – protein produced after a meal proportional to the energy content of the meal (decreases appetite)
Factors that are known to increase satiety and reduce cravings.
Increase in blood glucose levels
Nutrient absorption in the small intestine
What is the hunger hormone most notable?
It is a hormone that stimulates hunger. Ghrelin, mainly produced by the stomach, is distinctive in that it fuels hunger, It acts upon the hypothalamus to stimulate appetite.
It may also be involved in long term body weight control. Ghrelin has been shown to stimulate the part of the brain that secretes dopamine called the VTA. This secretion of dopamine can create strong memories and associations of eating certain foods with high amounts of pleasure. Thus having cravings and having a more emotional pull towards certain types of foods.
The levels of ghrelin increase before a meal and near an hour after the meal.
Also increases in ghrelin also led individuals to eat spontaneously when there were no food cues and also no time cues.
Why do you want to suppress ghrelin? Exercise induced weight loss over one year resulted in an increase in plasma ghrelin, which STIMULATES appetite. The appetite will be stimulated to help deter additional fat loss. If you are hungry (never fun) then you are going to eat more (halting any fat loss) making your workouts senseless.

Physiological systems within the body occur in the short and long term. These are important because it regulates the body’s metabolic processes.
There are certain hormones that either increase or decrease how much you seek out to eat until you feel satisfied. This is a complex dance between hormones, metabolism, the gut, and the brain.
When food is ingested, your stomach expands, receptors made up in the stomach lining send signals to the brain that it is time to decrease food intake. Concomitantly, there are vast amounts of processes and hormones within that process.
Factors decrease satiety
Hormones that enhance a sense of pleasure while eating referred to as beta endorphins, creating more food intake
Amino acid Neuropeptide Y, which stimulates appetite.
Decreased blood glucose levels such as an overnight fast.
It seems like we are at the mercy of our cravings by these pathways and hormones!
Maybe, but if we can understand them then we can mediate them as much as possible. Understanding the triggers, tribulations, and pitfalls that will impede your goal, you then create better habits around them.
You can take precautionary measures and being mindful of stimuli and cues that flip these craving switches.
Chocoholics get the fame most of the time with studies dealing with appetite. Walking can actually induce an appetite suppression effect.
Modifications you can use instantly
Understanding social circumstances and watching them, noticing what stressors, environmental triggers, cravings, and desires arise.
Determine the type of food you can moderate your intake on.
If there are certain foods you are constantly overindulge in and its damaging your fat loss you may want to refrain from having them, and find foods that are sweet and satisfying you like and can also have a moderate amount of.
Allow for moderation. If you cannot simply have a moderate quantity of a type of food you crave, such as cake or cookies, then eat something similar you can ingest in a smaller portion that does satisfy. Rather than the whole baker’s dozen.
How active are you. Do you walk a lot? Is there a lot of sitting involved in your job? The higher the stress and the more you move matters day to day.
Location of eating. Do you eat in front of the TV Do you eat at the office where there are a lot of high calorie choices? Distracted eating removes memory formation and doesnt send signals to your brain that you are full. More on eating less distracted here
Time you eat. If you get hungry at night try and allot your meals for later in the day or later at night. This will push back your satiety so you don’t over indulge and do not go to bed hungry.
Persons you eat with. Do you eat more when you are alone or with groups?
Emotional states. How do you feel when you eat? You might eat more when stressed, happy, or sad or vice versa
Just simply understanding how you interact with all of these states can help lead to behavioral change. The mere fact you are noticing these states and emotions arise is beneficial.
Keep foods that you cannot control yourself or overindulge on out of the home. Food that is available readily for consumption can potentially elicit stronger reward system activity than food that is not currently available for consumption this is referred to as “nudging”
Lessening accessibility of caloric dense and nutrient sparse food and increasing availability of low calorie foods and nutrient dense food in daily life.
Tips when buying foods
Buy foods closest to their natural state. Or second state, one that is just one process away from natural, such as frozen blueberries.
Do not shop when hungry.
Stay the majority of the time on the outside edges of the store, that is typically where the freshest food resides.
Make a list and do not splurge or stray from it.
How to reduce cravings
The type and quantity of food intake influences appetite and energy intake. Appetite-regulating hormones released from the gut in response to food intake provide feedback to the hypothalamus and, subsequently influence appetite.
Some ways to reduce cravings is dealing with satiety in the present meal. Eating nutrient dense food helps with satiety so you will be less likely to have urges. The more voluminous a food is, the more satisfying it is and reduces cravings and urges eating more.
Eating highly processed foods, with large amounts of refined carbohydrates and/or fat, are associated with behavioral symptoms similar to addictive eating. Additionally, foods with high glycemic load were especially related to addictive-like eating problems for individuals endorsing elevated symptoms of “food addiction.”
Glycemic load not only depicts the quantity of carbohydrates that are refined in the food but it also represents how quickly absorption and transference into the system occur. Similarly, addictive substances are concentrated and a fast pace in which it is absorbed. A lot of prominent research has proposed these high glycemic load foods have the capability of activating neural circuitry that is reward related parallel to the addictive materials. Consequently, increasing hunger, craving, and over-consumption of energy. (2). (3.)
Food cues in obesity and drug cues are different in some variations but there are also strong comparisons when it comes to neural responses when both are inducted to each of the individual substances separately. (4). (5).
Nutrition knowledge has been positively associated with diet quality
Food has to taste good as well. Making it “tasty’’ is important as well.
here are sound sources for understanding nutrition
There is other things that are simply unconscious that effect your intake. There is an effect referred to as – pack size effect. The larger the container food comes in, generally, the more energy intake is consumed from that food. Being cognizant and having a reminder that you do not need to eat mass quantities of cookies helps. If you are not mindlessly eating you have a much less risk for eating in a much more healthy and restrained manner. (6).
Moving consumers towards consumption of smaller portion sizes will require changes in consumer behavior as well as changes in products available to consumers in a variety of settings
The more militant you are the worse it is going to be. If you focus on removing all of the negative food rather than focusing on implementing healthy choices it greatly determines the overall success and well-being of the quality of the diet.
Your outlook on food matters. Your attitude matters quite a great deal in relation to your success and if your fat loss will be long lasting. You can’t beat yourself down by thinking negatively towards food
Even using side to side eye movements for short bouts have show to reduce choosing unhealthy snacks to healthy snack choices
Tips for accessing portions on food goods.
First look at the serving size and access the entire box, bag, or item is and process do you see yourself coming back to this item this number of times, does this box or bag look like it would satisfy 7 people if it was all prepared at one setting.
It’s important that your relation towards food isn’t negative. If you feel like you are being deprived or are going to be deprived in the future you are going to eat exponentially more in the present moment. The scheduling of a diet or a deprivation can trigger an onslaught of overeating at the present meal or next coming meal.
Setting goals, having help from your social circle and problem solving are known effective paths to travel when attempting behavioral change , (7)
Eating good nutritious foods you like is very important
Dietary cues matter. A habitual response to even just merely looking at the food label of a food or googling it with your phone IS A DIETARY CUE. This can greatly reduce your intake just by letting you remember you are conscious and in control of what you eat.
Militant restriction just leads to more and more cravings
Behavior intervention has been associated with a term called “clustering” where there were associations with healthy behaviors clustering together. Such as individuals who exercised were also significantly likely to eat healthy. This can be potentially powerful to behavioral change. If you alter a state in which you behave in just one aspect it can create momentum and have a much higher likelihood of altering other areas.
Mindfulness eating there have been a lot of thorough and promising findings in the relationship between psychological distress and patterns of emotional eating. Mindfulness has shown to suppress that. Here is an additional mindfulness eating article
There is a lot when it comes to understanding the systematic relation between the mind and body. But with some of these approaches you can limit and reduce the incessant pull of cravings and hunger. If you approach food with more of a holistic path and understanding that cravings happen then you are much closer to understanding what trigger points and pitfalls happen within them as well. Making it a multi-level approach, understanding the social cues, the physiological cues and environmental impacts that influence can extremely reduce your interaction to unhealthy eating and subjectivity to your cravings.
