Unfortunately for most of us, work lacks proper kitchens and reheated food is vastly inferior and harder to prepare. Plus you're not getting paid for the time cooking unless you work in a restaurant or as a house maid.
Lunch is a mediocre or inconvenient meal if you work, it's best to opt-out entirely. A protein shake is healthy and low calorie, and a couple of them spaced through the day will get you to dinner, at which point you've built up a nice calorie deficit, so you can enjoy yourself.
I used to be about 50lbs heavier then I am now (not 6 pack yet ) but I found most of your suggestions to be similar to what work for me. I make my meals in advance for work, if I can’t pack a meal I simply don’t eat. (For example. Lunch may be a tuna sandwich made with 1 can of tuna(110 calories) soy sauce (6 cal) low cal mayo (10 grams, 45 calories) and two slices of light bread toasted in advance (90 calories ) and carrots or celery or an apple if I’m feeling adventurous. )
Otherwise I prepar my meals, and mostly avoid snacking. If I snack it’s going to be some carrots or similar that I log in a tracking app.
Though now after a year of nearly continuous meal and excrsice tracking I have found I tend to eat appropriate sized meals.
People put food in the fridge to slow bacteria growth. This quote is from a USDA Health brochure
>Bacteria grow most rapidly in the range of temperatures
between 40 ° and 140 °F, doubling in number in as
little as 20 minutes. This range of temperatures is often
called the “Danger Zone.” That’s why the Meat and
Poultry Hotline advises consumers to never leave food
out of refrigeration over 2 hours. If the temperature is
above 90 °F, food should not be left out more than 1
hour.
Yet somehow people survived for a very long time without refrigeration. In fact, we evolved to live without it, so those bacteria are probably good for us if anything. Personally I don't even like to eat cold food as it diminishes the flavour.
It's super easy to bring food to work and just eat it at room temperature. But instead people insist on this weird fridge then microwave ritual then complain about it being too difficult.
Or maybe we didn't survive. Life expectancy was half what it is today for most of humanity up until 1900. Even if you remove childhood deaths, life expectancy was still only about 33 years in the Paleolithic era.
I don't understand the romanticization of a time period where it was normal for people to die before they were 40.
Life expectancy has increased mostly thanks to modern medicine and in particular drastically reducing infant mortality. Keeping food in the fridge at all times has no effect other than reducing your enjoyment of the food and making it less likely that you bring food to work, thus decreasing your overall health.
