Varies quite a bit. Looking at the past week:
Homemade sourdough toast, sausages, grapes
bagels with cream cheese and lox
hash browns with fried egg and homemade Hollandaise sauce
Carribean-style coconut-rice porridge with mangoes and limes

I made a habit out of making overnight oats.

I have a base mix of oats and seeds, like hemp, flax millet, sesame.. I mix it usually dried fruits, peanut butter, maple or beet sirup, banana, cocoa powder and not to forget a pinch of salt.

Add the twice the volume in milk and well, let it soak overnight. Just grab in the morning and ready to go

A bowl of nails, without any milk.

My current go to for the past few years is oatmeal. I mix oats, dry milk powder, frozen cherries, and water. Then I throw it in the microwave for a few minutes to cook. Once it's done, I add cinnamon and a handful of chocolate chips and mix it all together. It's probably not the most healthy option, but it's tasty and reasonably nutritious.

6 scrambled eggs made with butter, sour cream, salt and pepper.

I prefer to start the day with a big breakfast, eat a light lunch and then nothing until a moderate supper with a small, low carb dessert in the evening.

I find the large breakfast starts my day well and fatty foods keep me satisfied longer so I'm not tempted to snack throughout the day, especially while working from home where food is always available.

My go-to is a bagel with hummus, with a pot of Cuban coffee.

500 kcal of Soylent. Weekday or weekend, doesn't matter.

I'm southern european and some of these answers are giving me culture shock... Normally, a coffee would get me through the day until lunch and, if I'm especially hungry, I'll eat some pastries too. But the thought of having to eat plenty of eggs or anything that involves cooking so soon after waking up is giving me upset stomach. I realize this may not be healthiest option tho

Granola bar in the dark while I rush out the door, as nature intended

Steel cut oatmeal, cooks in less than 5 minutes. Mixed with honey and psyllium husk. Loads of fiber, sweet enough to get it down.

Cereal, mostly. Or other ‘breakfasty’ carbs. On the weekend I might “spice it up” with bacon and eggs and a glass of orange juice.

EDIT: also, wanted to add that consuming a bunch of fat tends to make you less hungry. So that’s normal. It should in fact be condusive to making you eat less, so long as you don’t eat way too many calories in fat.

Not much. Sometimes nothing. There's a Salvadoran bakery a block from my house though, so that's always tempting. Pastry, empanadas, or just a few rolls.

I don't normally eat in the mornings as I've been practicing intermittent fasting for years. Tea or coffee, lots of water usually.

Lunch is a feast, with dinner a slight step down from the volume eaten at lunch. Meats and fats provides a lot of energy and break down longer so that may be the reason for your reduced hunger. Just those alone isn't healthy for you in the long run, yeah.

2 slices toast, buttered, with marmite if I feel like it's worth the effort

Not sure if this has anything to do with me being Autistic but I eat the same thing every meal... pasta, with veggies and protein (depending on what I have). Breakfast just means additional coffee. If I really don't have time then it's bakery and fried burrito from the nearby supermarket.

Tried to have a more "typical" American breakfast for a while until I realized I'm lactose intolerant so that never went anywhere...

I’m pretty close to yours - I eat one half avocado, two eggs sunny side up, and then a dash of mayo in the center of the avocado and fill it generally with shrimps. For me this keeps me full for a good while and I feel healthy and with a good stomach.

I usually only eat one full meal before dinner, but I’ll often have a banana, protein shake and apple as well.

If I’m working from home I try to wait with “breakfast” until there is a good pause between meetings, usually around lunch.

I go through phases but I always end up back to two slices of buttery toast.

Other things I sometimes cycle through Overnight oats Weetabix Porridge (winter only) Jam on toast Poached egg on toast

I also like home made pancake on a weekend day (family activity) or if going out for breakfast/brunch a full English or a chorizo breakfast hash

I make "egg muffins" and freeze them to reheat every morning. To make these, I steam a bag of broccoli florets. I break these apart and put them into greased muffin tins. Then I add some shredded cheddar cheese and egg beaters. I bake these (400° for about 15 minutes or until done). Then, after they cool, I stick them in the freezer. I make sure I have 12 in a Tupperware tub in my refrigerator.

Every morning, I microwave 3 of them and have that with some whole wheat toast and cream cheese. (I take more out of the freezer as needed and they are mostly defrosted by the next morning.)

12-18oz of black coffee, a fried egg over last night's leftover rice or a packet of instant oatmeal. I eat very early so I'm hungry again around 10:30 so I have a Second Breakfast. Usually some canned fish since I find it pretty satisfying and because it can easily be prepared different ways. Usually "Mediterranean" sardines over chopped onions, herring over hopped giardiniera, or the classic plain sardines on hot buttered toast with hot sauce.

Currently smoothie with 1 cup milk, protein powder scoop, banana, handful of strawberries, handful of mango.

Previously half a bowl of oatmeal. Or toast.

I've never been a breakfast person either. But I used to do the "bullet proof " coffee thing. A tablespoon of unsalted butter and a tablespoon of mct coconut oil. I found that I wasn't as hungry by lunch time.
Fat and protein take a while to digest and can make you feel more full.
Definitely find an alternative to the butter sandwich though, that's a shit ton of calories.

I didn't used to be a breakfast person either, but I've been trying to move my food intake earlier in the day, it's supposed to be healthier. So, one of: plain yogurt with honey and fruit, one scrambled egg in an omelette with Parmesan cheese, or a bagel with butter. Almost always vegetable juice, and a multivitamin. Always always 2 cups of coffee. Depends on what's around and I feel like.

I make a smoothie every morning. Right now it's with frozen banana and berries, beet powder, moringa powder, and hemp and chia seeds. I used to do banana, berries, fresh spinach, and protein powder, but protein powder is too expensive right now.

A peanut butter jelly sandwich.

Tears. If I'm lucky, iced tea.

Svunt Shake, just with one cup oat milk and one cup whole milk instead of two whole milk. Helps me reach my calorie goal per day (I tend to undereat).

Tea and two slices of bread and cheese. Sometimes a bit of orange juice with it. Alternatively, yogurt with some granola,but not very frequently.

I do an egg sandwich (English muffin toasted, egg whipped and then fried in an egg circle, cheese). My trick to continually enjoying my sandwich is that I buy fancy chedder for it from the cheese store. I usually put a little Italian dressing on the English muffin for flavor.

I usually make a Smoothie that consists of a banana, some plain fat-free yogurt, 1 scoop chocolate Orgain protein powder, about 1/2 cup almond milk, and some frozen blueberries. Sometimes I add Chia seeds, instant coffee, or cocoa powder. This smoothie is filling enough for me til I need a small snack around 3:00.

On weekdays, bread with something on it. If I'm planning on a really hard day, I might make a sunny egg and put it on a toast so that I don't starve 3 hours later.

The only thing I have for breakfast on the daily is my zero sugar energy drink and my antidepressant then wait till lunch for a meal.

I'm not a morning person. I wake up late and go to bed late, so I actually never eat in the morning.

I’m not a morning eater, usually just 1 banana or maybe a bowl of plain cheerios

I get my energy from coffee in the morning

It depends. During the work week, I'm awake before I've developed an appetite and settle for a banana and a coffee. Specifically cold brew espresso with a splash of whole milk and a scoop of chocolate flavored whey protein powder.

On the weekends though, I wait until 10 or 11 before I eat so I can savor a bigger meal. Typically bacon, eggs, and some diced red potatoes all cooked in the same cast iron pan. If I'm feeling frisky, I might whip up some French toast or pancakes as a side.

Ass.

Energy drinks

I like Ezekiel cereal, or toast. I think it's important to start the day with whole grains of some sort.

This week I started eating a butter sandwich as soon as I wake up in the morning. And when I say “butter sandwich” I’m talking about eight pats of butter between two slices of whole wheat bread.

About 450-500 Calories, 30% Carbohydrates, 6% Protein, 64% Fat (two-thirds of that is saturated fat) -- that's with regular bread, whole wheat improves this somewhat.

Why is this so satisfying? I’m not hungry until late in the afternoon, at which point I just wait until dinnertime.

It's because the fat content. It's got enough carbs (fast arc energy) to take care of an immediate hunger. It's got a lot more fat (slow arc energy) that gives you long-lasting satiety.

I’d like to lose some weight, and with these butter sandwiches I’m consuming much less food during my day, but they can’t be healthy for me. Clearly I don’t know how nutrition works.

I've learned this as I went along. I went from 298 lbs to 171 and I've kept it off for 8 years so far. Think of it as a series of trade ups that you make along the way when you learn thing and you are ready to do them. Doing too much too fast is how to get frustrated and quit.

To lose weight, we have to take in less energy than we burn and the proverbial average person burns about 2000 Calories a day. To get enough food for basic nutrition (essential fatty acids, enzymes, minerals, vitamins) we need to eat enough and eat through a wide variety of healthy food through the week. Most of us can cut back 25%-33% of what we were eating before and shed some pounds, so the rest has to be good with nutrition.

Missing in your breakfast and lack of lunch are sources of sufficient protein (such as some meat for example) and vegetables which provide a lot of our vitamins and minerals. But like you said, this is good for weight loss. Now make it smarter in some way, in YOUR way. Don't try to aim for the optimal way, but what's a veggie (or fruit) you might add or have on the side with it? When you choose it, it's easier to make happen. And some fruits are pretty portable and you can have it later that day and prevent that afternoon hunger.

On the constructive criticism side, butter is a saturated fat and the Heart Association recommends aiming for a dietary pattern that achieves 5% to 6% of calories from saturated fat to avoid health problems. The 8 pats of butter are just under 300 Calories and 120 or so would be the Heart Association's recommended amount. But, here too, trade up and do baby steps. It's a journey and it has to stay your diet and not be too weird to you. You can choose a butter-like spread that is mostly unsaturated and satisfy both your taste buds and your heart needs.

What do you eat in the morning?

A bowl of 0.5c Cheerios, a few nuts, some milk, and a fruit -- all mixed together. It's small, only about 250 Calories, but I eat again mid-morning when the spouse wakes up. Our main big meal is before noon. We have a light supper later, sometimes what other Americans would think of as a lunch, such as soup and salad.

Or if you are familiar with the McDonald's Sausage McMuffin with Egg, I make my own with turkey sausage. If I don't have that cereal/fruit/nut thing above, I make this.

When I want to feel full in the morning, I find that pinto beans does the trick. They're also a good source of fiber and potassium.

Or if I'm not feeling very hungry, a protein shake with some chia or flax seeds added to the mix.
