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

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.

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

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.

A bowl of nails, without any milk.

Black coffee One apple One banana 500ml banana flavoured pea protein isolate

I'm not thrilled about consuming so much of the pea protein isolate, however I'm now actually seeing progress in my workouts so that's nice! I'm looking at replacing it with a source of protein that's a bit more natural, or atleast not processed to high heaven.

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

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

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

@TheBaldness I don't always eat breakfast, but when I'm hungry in the morning I eat a lye roll without anything. They're less calories than a crossiant, and because of the lye they're not as dry as a normal bread roll.

Lately, steel cut oats with half a banana and 250ml of kefir. I actually hate eating breakfast. I was into Intermittent Fasting for years and did 18/6 almost every day, but then I was diagnosed with diabetes and my doctor told me to stop IF if I wanted my meds to work as they should without causing low blood sugar.

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.

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

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

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.

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.

Energy drinks

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

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.
