>>937615711 (OP)Yeah, fill up on raw leafy greens like spinach and kale, as well as other greens like broccoli, asparagus, and peas. You can use canned peas. If you just shove this shit into your mouth when you feel like you "need a snack", you'll sate your hunger while putting great dietary fiber into your body plus a shitload of micronutrients that WILL make a difference on your mood and energy.
You may still "crave" sweetness: switch to peanut butter and don't overdo it. It legitimately replaces the urge to eat chocolate and bullshit like oreos or cheesecake if you have even a little bit of willpower. Eat red beans because black beans taste like water and mush, and cut out milk, juice (especially anything artificial like Sunny D, Capri Sun), and basically any liquid that isn't water.
If you're trying to drink a lot of water but it makes you feel sick even when you don't have a lot, you're probably low on electrolytes like sodium, potassium, and magnesium. First, take a Flinstones multivitamin every morning; then, put salt in your foods if water makes you feel that way, and have (NO MORE THAN) two bananas a day for potassium. Maybe take a magnesium supplement if your multivitamin doesn't cut it.
Lentils, oats, nuts (almonds and pistachios are good) - but don't get ridiculously loaded Planters nuts designed to trick fatsos into thinking they're healthy. Avoid sugar except from fresh fruits - blueberries, raspberries, watermelon (barely anything in it), and the occasional apples or grapes; and again, don't overdo it.
Try to stay busy - LONG WALKS are GOAT-tier. Do that and if you don't lose weight, you're a lying piece of shit. That is the core of the "Blue Zone" dietary type. Look it up.
