Preferably something that has little to no preparation required.

  • Oatmeal and yoghurt.
    You can switch it up with fruits, nuts, syrups (like maple) etc.

    My goto is:
    Oatmeal, plain yoghurt (3.5%) or greek (10%), passion fruit, apple, maple syrup (if I like it sweet).

    This will certainly fill you, has lots of vitamins and depending on how much and what you do is easy to eat.

        • Fast as in the non-eating time since last meal or fast as in quick? I might have missed the original question… If it’s the latter, there’s plenty of quick, filling meal items in the morning. When I was serious about weight lifting, I would drink a protein shake 1-3 times a day to supplement muscle-building.

          As for the former, intermittent fast-ers are adamant that anything other than water, plain coffee/tea will break their fast and provide less benefits.

          I don’t know, but wonder if there is a scientific basis for this. If you’re avoiding eating something that’s going to fill you up (ie protein), my reaction is kind of “why bother”…

  • Overnight oats. Look up recipes, but you mix stuff together the night before and just eat it with a spoon out of the jar the next day. For optimizing the morning routine, nothing is simpler.

  • Oatmeal. You can customize it to what you need and your tastes. It just needs liquid for the oats and whatever additions you want to do. I use chia seeds and flax seeds for protein & fiber, and add frozen fruit and vanilla soy milk. Microwave and enjoy.

    Peanut butter, dried fruit, honey, fresh fruit, etc. are all good choices

    • I have little meal prepped oatmeal jars I set up. Everything is pre-measured just add a cup of water and pour in the jar, boil and you’re done. They have oats, brewers yeast, salt, pepper, garlic powder, and sometimes whey protein (that one changes how you have to hear it though to prevent weird clumping). Throw a fried egg on top of I have time, or a scoop of cream cheese to mix things up

  • A bottle of Soylent contains 400 calories. It contains exactly 20% of each RDA-recognized vitamin, about 30 grams of carbs, a healthy balance of fats, and protein. Preparation is shaking the bottle for about three seconds, and peeling off a little foil seal.

    Used to be you couldn’t drink it fast without getting digestion issues but now they’ve added enzymes to help digest the oats, so you can chug that bottle without issue.

    A little more expensive than groceries you prepare, but cheaper than any buyable prepared breakfast you’d get from a coffee shop, diner, convenience store, or fast food joint.

  • A serving each of full fat Greek yogurt, peanut butter, and chocolate protein powder all mixed up. It forms a mousse and is yummy. Takes a minute to make and a couple minutes to eat, lots of protein and fat so it keeps you going way longer than it should. I mix the PB into the yogurt first then mix in the protein, that helps it mix better.

  • Fil (fermented/soured milk) and musli in my opinion cannot be beaten. Get bowl, open fridge to get fil, pour fil into bowl, get muesli, add that and you are done. Pretty unprocessed, plenty of fiber and (depending on variety) lots of good bacteria. Cleaning up is also quick, water and a few swirls with the brush. Making coffee takes longer than chomping down on a bowl of fil and muesli.

  • Sorry, I only have the filling, easy to eat, and no prep parts to give you. I’m no health expert, just a lazy Lemming.

    Normally my daily routine is a bowl of Cereal with milk. I have a banana sometimes with it. Zero prep.

    If I need to count on having energy for the whole day, it’s an over easy egg on buttered toast with margarine and black pepper. Some prep required.

    My unhealthy “dinner for a week” meal is a pack of Costco hotdog buns and sausages that I cook two at a time whenever I want and slap mustard on it. That’s 8 or so meals for just over $20.

    I could cook more and better stuff but I’m just too lazy to do the prep, the cooking and the cleanup, but I’m also too cheap to do takeout more than once a week.

  • NO PREP: A couple slices of smoked salmon. A few cherry tomatoes. Another fruit of your choice (apple, orange, berries, etc.)

    Substitute similar things for variety: Smoked mackrel, whitefish, trout, or herring. Vegetables like cauliflower, broccoli or snap peas instead of cherry tomatoes. Fish not your thing (too bad cause it’s VERY healthy) then eat sliced meats. Leaner is healthier.

    ANOTHER LOW PREP OPTION: Charcuterie board. Make it in a big glass storage container and keep it in the fridge so all you have to do is take it out. Graze. Put it back. These can have almost endless foods on them, but choose wisely. No candy, Nancy! Eat some nuts.

    For years I ate cereal with milk and was still hungry. Stop being a bitch and putting sugar on your sugar and eat real food.
