Why do you feel hungry even if you had enough calories? Are hunger and calories related?
It's well known that high carbohydrate consumption can trigger food cravings in the brain, despite eating enough. Effects of dietary glycemic index on brain regions related to reward and craving in men

down on carbs to curb hunger, especially low nutrient carbs like sugars

instead.
I used to count calories.
It was part of my training as a dietitian – one of our homework
assignments. It seemed everyone in my class was really good at it, like
they had memorized the calorie content of a bunch of foods. I treated
the project as more of an experiment. I mean, if this is what we’re
supposed to have our patients do, I should be able to do it.
The funny thing is, the more I counted calories, the less I
was paying attention to the food in front of me. It was like looking at
a spreadsheet on a plate. All you see is numbers.
I’d choose the less tasty entree because it was lower in
calories, even if it didn’t sound appealing. If I got hungry after the
meal, I’d second guess myself. “But I ate 700 calories!? That should be
enough!”
It was like a battle between the calculator and my stomach.
The calculations said I needed a certain amount of calories per day. If
I went over, it was a “bad” day. If I went under, it was an excuse to
eat junk food. I’d think to myself, “Well, these chocolates are only 90
calories…”
I’ll admit, I failed miserably at counting calories and
gave up within a few weeks. I never really enjoyed it and I felt
restricted, like I was going to develop disordered eating. I questioned
the accuracy of all the calculations. There are a number of formulas to
choose from and they all give you different answers. I couldn’t memorize
the nutrition facts like my classmates, and frankly, I got tired of
feeling like I belonged in the remedial nutrition class.
Now, I actively encourage my clients to stop counting calories and here’s why.
6 Reasons to Stop Counting Calories
1) Labels can lie.
Seriously. Labeling laws allow a 20% margin of
error on the nutrition facts panel. That means your 100-calorie snack
pack could be 119 calories. Or that 500 calorie TV dinner could be
nearly 600 calories. Legally. Ooops.
“[T]he ratio between the amount obtained by laboratory
analysis and the amount declared on the product label in the Nutrition
Facts panel must be 120% or less, i.e., the label is considered to be
out of compliance if the nutrient content of a composite of the product
is greater than 20% above the value declared on the label.” (FDA
Guidance for Industry: Nutrition Labeling Manual)
2) Nutrients vary by season, variety, ripeness, etc.
While it’s nice to have the nutrient analysis of foods, there is no way food companies or the USDA could analyze every variety of tomato from every region from every
season from different growing conditions (i.e organic vs. conventional)
and every other variable for nutrients, including calories. That super
sweet summer tomato likely has more calories (and valuable nutrients)
than that tasteless, pink one from the dead of winter. Which one would
you rather eat?
3) “More calories equals weight gain” is not an exact science.
If calorie counting worked long term, America would be the
thinnest country in the world. We are a nation of compulsive dieters and
you wouldn’t know it looking at us. Turns out the composition of what
you’re eating is crucial to how many calories you eat and how many
calories you burn.
The quality of the calories going in can affect the number of calories being burned off. – Dr. Ludwig, obesity researcher
In a study comparing 3 diets: low-fat, low-glycemic, and
low-carb, the people on the low carb diet burned 350 calories more than
the low-fat diet. (JAMA, 2012) And yet, our nutrition guidelines
recommend a low-calorie, low-fat diet. Trouble is, when you focus on
calories, you’re likely to eat less fat (since fat is more calorie-dense
than carbohydrate and protein). And when you eat less fat, you’re
likely to eat more carbohydrates. See the problem?
If you’re happy eating tasteless, low-fat food, going hungry and not
losing weight, by all means, count calories and cut fat out of your
diet.
4) We don’t absorb all calories.
It’s true! A study on almond consumption in humans found
that up to 20% of the calories were not absorbed. (J Agric Food Chem,
2008) The exact reason is unknown, but possibly due to the “cellular
structure” of nuts and the way our bodies digest food. I would speculate
that we absorb a lot more calories from highly processed foods. Maybe
that’s just me.
Or maybe not.
In summary, a calorie is not necessarily a calorie: given
the functional differences between edible plants, interfamily and even
interspecies differences must be considered when making comparisons
between food processing techniques. (Proc Natl Acad Sci, 2012)
There’s also good evidence that our gut health (and gut
bacteria) plays a role in how many calories we absorb from our food.
(Amer J Clin Nutr, 2011)
5) Focusing on calories often means we restrict healthy foods.
This especially happens when it comes to fat. We often omit
higher fat foods simply because they are higher in calories without
taking into consideration what benefits we might get from them, such as
staying fuller for longer (hangry much?), absorbing antioxidants from vegetables, and getting necessary nutrients, like fat-soluble vitamins. (This is crucially important for pregnant women who may become deficient in key brain-building nutrients if they restrict fat.)
I choose to fully ignore calorie labels, especially on real
foods that are naturally high in fat such as meat, fish, eggs, cheese,
butter, avocados, olives, nuts, and seeds. My body likes these foods,
there are benefits to eating them, and I don’t need a calorie count to
tell me otherwise.
6) Too much math.
Honestly, I don’t have time or energy to calculate
everything that goes into my mouth. That probably sounds odd, since my
life’s work is helping people improve their health by eating better, but
I firmly believe this can be done and is best done without counting. (And I have satisfied clients to prove it.) Counting calories is especially fruitless when you know #1-5.
So now you might be wondering:
If I think calorie counting is a such waste of time, what do I do instead?
How do I prevent myself from eating too much?
How do I stay at the same weight, year after year? (and help my clients do the same)
My answer is simple.
11 things I do instead of counting calories:
- I listen to my body.
- I always eat when I’m hungry. (Here’s how to know if you’re truly hungry.)
- I eat foods that I’m actually in the mood to eat.
- I put my full attention on the meal in front of me.
- I notice the sensations in my body before, during, and after eating.
- I sit down when I eat.
- I chew every bite before taking another.
- I savor the flavors, texture, mouth feel, sounds, richness, crunchiness or softness, saltiness or sweetness.
- I make an effort to eat healthy foods and make an equal effort to eat the healthy foods that taste good to me.
- I sometimes choose to eat foods purely for the pleasure of eating them, even when they are not “healthy”.
- I sometimes choose to eat more food than is comfortable,
either because the food tastes really good or because I know I wont have
time to eat again for a while (such as during a busy work day).
If this sounds like a breath of fresh air, I’m with you.
Just putting this down on paper (or rather, in html) feels like a weight
has been lifted off my shoulders.
I stopped feeling like a disobedient dietitian when I let
go if this whole counting obsession. There’s a certain sense of freedom
that comes from eating in the way we are meant to eat.
It’s sustainable and enjoyable. It frees up so much time
and energy to spend on things that actually matter to you. And in the
process, your body will naturally find a healthy weight.
It’s empowering to know that your body knows best.
It validates all of those signals your body sends you moment to moment,
even the urge to eat a little something extra at the end of a meal.

To lose weight, you generally need to reduce your daily calorie intake.
Unfortunately, weight loss diets often lead to increased appetite and severe hunger.
This can make it extremely difficult to lose weight and keep it off.
Here is a list of 18 science-based ways to reduce excessive hunger and appetite:
1. Eat Enough Protein
Adding more protein to your diet can increase feelings of fullness, make you eat less at your next meal and help you lose fat (1, 2).
For instance, a weight loss study compared two breakfasts identical in calories: one consisting of eggs, the other of bagels.
Participants who had the egg breakfast lost 65% more weight and 16% more body fat over the eight-week study period (3).
In addition, a high protein intake may help to prevent muscle loss when daily calories are reduced for weight loss (4).
Making protein about 20–30% of your total calorie intake, or
0.45-0.55 g/lb of body weight (1.0–1.2 g/kg), seems sufficient to
provide the benefits (4).
Bottom Line: Getting sufficient protein in your diet can help promote weight loss, partly by decreasing your appetite.
2. Opt for Fiber-Rich Foods
A high fiber intake stretches the stomach, slows its emptying rate and influences the release of fullness hormones (5, 6).
In addition, fiber can ferment in the bowel. This produces short-chain fatty acids thought to further help promote feelings of fullness (7, 8).
In fact, a recent review reports that adding fiber-rich beans,
peas, chickpeas and lentils to your meal can increase feelings of
fullness by 31%, compared to equivalent meals that aren’t based on beans
(9).
Fiber-rich whole grains can also help reduce hunger and keep you feeling full (7).
Eating an extra 14 grams of fiber each day may decrease your calorie
intake by up to 10%. Over 3.8 months, this could lead to a loss of up to
4.2 lbs (1.9 kg) (10).
However, more recent reviews observe less dramatic effects. This may have to do with the different types of fiber studied (11, 12).
More viscous types of fiber like pectins, beta-glucans and guar gum seem more filling than less viscous types of fiber (12, 13, 14).
What’s more, few negative effects have been linked to high-fiber diets. Fiber-rich foods often contain many other beneficial nutrients, including vitamins, minerals, antioxidants and helpful plant compounds (11, 12).
Therefore, opting for a diet containing sufficient fruits, vegetables, beans, nuts and seeds can also promote long-term health.
Bottom Line: Eating a fiber-rich diet can decrease hunger and help you eat fewer calories. It can also promote long-term health.
3. Pick Solids Over Liquids
Solid calories and liquid calories can affect appetite differently.
One recent review found that compared to a solid snack, people who
ate a liquid snack were 38% less likely to compensate by eating less at
the next meal (15).
In a second study, participants who were fed a semi-solid snack
reported less hunger, a lower desire to eat and a greater sensation of
fullness than those fed a liquid snack (16).
Solids require more chewing, which can grant more time for the fullness signal to reach the brain (17).
Scientists also believe the extra chewing time allows solids to stay
in contact with the taste buds for longer, which can also promote
feelings of fullness (18).
Bottom Line: Eating your calories rather than drinking them can help you eat less without feeling more hungry.
4. Drink Coffee
Coffee has many benefits for health and sports performance — and may also help decrease your appetite.
Research shows that coffee increases the release of peptide YY (PYY). This hormone is produced in the gut in response to eating and promotes a feeling of fullness (19, 20).
Scientists believe that PYY levels play an important role in determining how much you’re likely to eat (21).
Interestingly, decaffeinated coffee may produce the highest reduction in hunger, with effects that last up to three hours after consumption (19).
However, more studies are required to pinpoint exactly how this works.
Bottom Line: Drinking coffee, especially decaf, could help reduce hunger for up to three hours.
5. Fill Up on Water
Drinking water can help decrease the hunger you feel before meals.
It may also increase feelings of fullness following a meal and promote weight loss (22).
In fact, studies show that people who drink two glasses of water
immediately before a meal eat 22% less than those who don’t drink any
water (23).
Scientists believe that about 17 oz (500 ml) of water is sufficient
to stretch the stomach enough to send signals of fullness to the brain (23).
That said, water is also known to empty from the stomach quickly. For
this tip to work, it may be best to drink the water as close to the
meal as possible.
Interestingly, starting your meal with soup may act in the same way.
Researchers observed that eating a bowl of soup immediately before a
meal decreased hunger and reduced total calorie intake from the meal by
about 100 calories (24).
Bottom Line: Drinking low-calorie liquids before a meal can help you eat fewer calories without leaving you hungry.
6. Eat Mindfully
Under normal conditions, your brain knows whether you’re hungry or full.
However, eating quickly or while you’re distracted can make it more difficult for your brain to recognize these signals.
Solve this problem by eliminating distractions and focusing on the foods in front of you — a key aspect of mindful eating.
Research shows that practicing mindfulness during meals
can help people experience more pleasure while eating. This can help
keep the focus on quality rather than quantity, and reduces binge eating
behavior (25).
There also seems to be a link between hunger, fullness and what your eyes see.
One experiment offered two identical milkshakes to participants. One
was called a “620-calorie indulgence,” while the other was given a
“120-calorie sensible” label.
Although both groups consumed the same amount of calories, hunger hormone levels dropped more for those who believed they drank the “indulgent” drink (26).
Believing that a drink contains more calories can also activate the brain areas linked to feeling full (27).
How full you feel may be influenced by what you see, and paying attention to what you eat can be very beneficial.
Bottom Line: Eating mindfully has been
shown to decrease hunger and increase feelings of fullness. It can also
reduce calorie intake and help prevent binge eating.
7. Indulge in Dark Chocolate
The bitterness of dark chocolate is thought to help decrease appetite and diminish cravings for sweets (28).
Researchers also believe the stearic acid in dark chocolate can help slow digestion, further increasing feelings of fullness (29, 30).
Interestingly, the simple act of smelling this treat might produce the same effect.
One study observed that simply smelling 85% dark chocolate decreased
both appetite and hunger hormones just as much as actually eating it (31).
Nevertheless, further studies are needed to examine the effects of dark chocolate on feelings of fullness.
Bottom Line: Eating or even just smelling dark chocolate may help diminish appetite and cravings for sweets.
8. Eat Some Ginger
Ginger has been linked to many health benefits. These include reductions in nausea, muscle pain, inflammation and blood sugar levels (32, 33, 34, 35).
Interestingly, recent research adds another benefit to the list: hunger reduction.
One study found that consuming 2 grams of ginger powder diluted in
hot water at breakfast reduced the hunger participants felt after the
meal (36).
However, this study was small and more research in humans is needed before strong conclusions can be reached.
Bottom Line: Ginger may help decrease feelings of hunger, but more research is needed to confirm this effect.
9. Spice Up Your Meals
Ginger may not be the only hunger-reducing spice.
A recent review examined the effects of capsaicin, found in hot peppers, and capsiate, found in sweet peppers.
It found these compounds may help decrease hunger and increase feelings of fullness (37).
What’s more, the ability of these compounds to generate heat may also increase the number of calories burned after a meal (37).
However, these effects have not been seen in all studies and remain
small. In addition, people who eat these foods often may develop a
tolerance to the effects.
Bottom Line: Compounds found in hot and sweet peppers may help curb hunger and increase fullness, but further research is needed.
10. Eat on Smaller Plates
Reducing the size of your dinnerware can help you unconsciously
reduce your meal portions. This is likely to help you consume less food
without feeling deprived (38).
Interestingly, this effect can fool even the most aware eater.
For instance, a study observed that even nutrition experts
unconsciously served themselves 31% more ice cream when given larger
bowls (39).
Another study further reported that participants who served
themselves snacks from large bowls ate 142 calories more than those who
ate from smaller bowls (40).
Bottom Line: Eating from smaller plates may help you unconsciously eat less without increasing your feelings of hunger.
11. Use a Bigger Fork
The size of your eating utensils may have dramatic effects on how much food you need to feel full.
One study observed that participants who used bigger forks ate 10% less than those eating their meals with a smaller fork (41).
The researchers speculated that small forks may give people the
feeling that they are not making much progress in satiating their
hunger, leading them to eat more.
Of note, this effect does not seem to apply to the size of all
utensils. Larger serving spoons may increase the food eaten at a meal by
up to 14.5% (39).
Bottom Line: Using larger forks may help decrease the amount of food needed before reaching fullness.
12. Exercise
Exercise is thought to reduce the activation of brain regions linked
to food cravings, which can result in a lower motivation to eat (42).
It can also reduce hunger hormone levels, while increasing feelings of fullness (43).
Research shows that aerobic and resistance exercise are equally
effective at influencing hormone levels and the size of a meal eaten
after exercise (44).
Bottom Line: Both aerobic and resistance exercise can help increase fullness hormones and lead to reduced hunger and calorie intake.
13. Lose Body Fat Around Your Middle
Neuropeptide Y (NPY) is a hormone that influences appetite and energy balance.
Higher NPY levels are believed to increase appetite and may even change the percentage of calories you store as fat (45).
Interestingly, researchers have discovered that body fat, especially
the type found around your organs, may increase production of NPY (46, 47, 48).
Because of this, losing weight around your middle may help reduce your appetite and hunger levels.
Bottom Line: Losing fat around your middle may reduce levels of the hormone neuropeptide Y. This may lead to reduced appetite and hunger.
14. Get Enough Sleep
Getting enough quality sleep can also help reduce hunger and protect against weight gain.
Studies show that too little sleep can increase hunger and appetite
by up to 24%, and decrease levels of some fullness hormones by up to 26%
(49, 50).
Research also shows that individuals who sleep less than seven hours
per night rate their fullness levels after breakfast as 26% lower (51).
It’s worth noting that several studies also link short sleep,
generally defined as less than six hours per night, with up to a 55%
higher risk of obesity (52, 53, 54, 55, 56).
Bottom Line: Getting at least seven hours of sleep per night is likely to reduce your hunger levels throughout the day.
15. Reduce Your Stress
Excess stress is known to raise levels of the hormone cortisol.
Although the effects can vary between individuals, high cortisol is generally thought to increase food cravings and the drive to eat (57, 58, 59, 60).
Stress may also decrease levels of peptide YY (PYY), a fullness hormone (61).
In a recent experiment, participants ate an average of 22% more
calories after a stressful test when compared to a non-stressful version
of the same test (62).
Finding ways to reduce your stress levels may not only help curb hunger, but also reduce your risk of obesity and depression (63, 64, 65).
Bottom Line: Reducing your stress levels may help decrease cravings, increase fullness and even protect against depression and obesity.
16. Eat Omega-3 Fats
Omega-3 fats, particularly those found in fish and algae oils, have the ability to increase levels of the fullness hormone leptin (66).
A diet rich in omega-3 fats may also increase fullness after meals when calories are restricted for weight loss (67).
So far, these effects were only observed in overweight and obese
participants. More research is needed to see if the same applies in lean
people.
Bottom Line: Omega-3 fats may help decrease hunger for overweight and obese people. However, more research is needed in lean individuals.
17. Opt for Protein-Rich Snacks
Snacking is a matter of personal choice.
If it’s part of your daily routine, you may want to choose snacks that are high-protein rather than high-fat.
High-protein snacks can increase feelings of fullness and decrease total calorie intake at the following meal.
For instance, a high-protein yogurt decreases hunger more effectively than high-fat crackers or a high-fat chocolate snack (68).
High-protein yogurt eaten in the afternoon may also help you eat
approximately 100 fewer calories at dinner, compared to the other two
options (68, 69).
Bottom Line: Eating a protein-rich snack will likely decrease hunger and may prevent you from overeating at your next meal.
18. Visualize Eating the Foods You Crave
According to some researchers, picturing yourself indulging in the
foods you crave most may actually decrease your desire to eat them.
In one experiment, 51 participants first imagined eating either three
or 33 M&Ms before being given access to a bowl of the candy. Those
who imagined eating more M&Ms ate 60% less of the candy, on average (70).
The researchers found the same effect when they repeated the experiment using cheese instead of M&Ms (70).
It seems that the visualization exercise may trick your mind into
believing you’ve already eaten the desired foods, significantly
decreasing your craving for them.
Bottom Line: Visualizing yourself eating the foods you crave may reduce your desire to eat them.
