With an account, you can revise, criticize, and comment on ideas, and submit new ideas.Here I will build a list of essential vitamins and minerals, and their sources. It is my amended version of the list featured in How to Heal Your Metabolism by Kate Deering. Sources described are for the diet I have designed for myself, and are not exhaustive.

Sources: salt, cheese, shrimp, oysters
Zinc
Functions:
- Opposing heavy metal toxicity

Sources: oysters, beef, beef liver, beef kidney, shrimp, cheese, yoghurt, eggs
Copper
Functions:

Sources: milk, cheese, eggs, beef liver, beef kidney
Most people are overnourished. One way to take control is to measure your daily energy expenditure and not eat above that.
Using an online calculator like https://www.calculator.net/calorie-calculator.html, you can get a decent estimate of your daily caloric needs (aka your caloric maintenance).
Then, using https://cronometer.com/, track your food to ensure you don’t exceed your daily caloric needs.
By eating in a 500-calorie deficit, you can lose about a pound per week. Lift heavy weights a couple of times a week so the weight you lose is fat, not muscle.
Avoid a prolonged deficit. Eat high-quality foods so you get all the macro- and micronutrients you need (Cronometer will tell you). Recalculate your caloric maintenance once a month or so to make sure you don’t hit a wall.
This is a simple way to do body recomposition.
The easiest lever to pull when trying to lose weight is satiation. That can be done artificially through GLP1-agonists, but in the case of nutrition, that's best accomplished by an increased protein and fibre intake.
Correct me if I’m wrong, but potatoes seem to be a good source of fiber. Very filling, also due to their high water content.
Carbonated water and diet sodas also feel filling, and they don’t even have calories. Diet sodas can help people lose weight. I like to drink Diet Coke when I’m on a cut. The caffeine gives me energy.
Some people think if they’re hungry that means they’re losing fat. I think that’s wrong.
You can eat a single meal at Cheesecake Factory for 2500kcals and be hungry again an hour later.
Or you can eat low-calorie foods throughout the day and not get very hungry until it’s actually time to eat again.
Some people might have trouble reaching their maintenance calories if they ate nothing but chicken breast, boiled potatoes, and broccoli for a day. They’d feel very full throughout the day.
I don’t expect much correlation, if any, between how satiating and how calorically dense some food is.
The good news for people who enjoy volume eating is that you can eat a lot while losing fat as long as you do it right. That means foods high in fiber and/or water (again, potatoes) and lean proteins. Vegetables generally work well.
The most important thing for fat loss is a calorie deficit, not hunger. Hunger is not a reliable indicator that you’re losing fat. You could be losing fat without being hungry, or you could be gaining weight while being hungry often.
Don’t go off of feelings. Count calories, macronutrients, and fiber, and weigh yourself to track progress.
Factory-farmed pork and chicken are bad choices. Sufficiently so that it's worth stressing, rather than saying their well-fed counterparts are tastier or somewhat preferable.
Fiber-rich vegetables like lettuce, greens, and salads should be part of your diet.
Whole grains, nuts, and legumes are health-promoting staples.
Nuts in moderation. Very calorically dense, easy to overeat.
Nicotine from non-smoking sources can be a useful health or cognition tool.
One is that it's a way of reducing body fat, and overweight is likely a bigger problem for many people than potential short term negatives of fasting.
Eating dinner earlier can be beneficial to sleep because digestion raises body activity.
Less constant feeding can improve blood sugar swings and insulin sensitivity because every time you eat, your body has to run the insulin system again.
You can just eat fiber with your meals instead, that will slow down insulin secretion afaik.
Protein above 0.8 g/kg of lean mass is desirable, often up to around 2 g/kg.
Per kg of lean mass. Someone who weighs 150kgs does NOT need to eat 300g of protein.
I could see that. Milk is hydrating. Yogurt is a good source of calcium and protein. Can go with low-fat or fat-free options to reduce calories.
I tried to look for good arguments against eating dairy for it being dairy and I cannot find any.
Yes. Fat is calorically dense and easy to overconsume, especially from hyper-palatable foods which are often greasy. I try to eat around 60g of fat per day.
