I don't know on how to keep track of the amount of calories and protein I intake. I believe I know how much calories and protein I have to intake regularly from the TDEE and Protein calculator, but not every food I intake will mention on how much calories and proteins it has. It also doesn't help that I find too many sources about what to eat that I don't know where to start.
Protein intake is actually vastly overrated. There is no significant benefit in any aspect of muscle building, strength or general health in consuming more than 60g of protein daily, 80g is probably the best amount to aim at when wanting to grow muscle
Mind you, muscles grow incredibly slow and your body doesn't need much protein for regular function. Also, don't sweat about bioavailability too much, anything above 70 is good enough
Just eat healthy. Swap out white carbs for dark ones, don't consume added sugar, nothing deepfriend, not too many saturated fats, lots of fiber... Like, just remember that any fruit, vegetable, legume, grains, milks, eggs and lean cuts of meat are healthy in their "unaltered" state, and that some processed foods like dark bread or soy milk are also very healthy
Another problem could be that when I work from home, whilst I usually have white wraps with chicken, sometimes it can be a problem when I don't have enough chicken or pita bread. This ends up me having sausages or ramen for lunch, the former might not be great due to the amount of oil. I have been thinking to just buy more supplies, but I am wondering if there are more reliable backup plans.
Just keep some trail mix or joghurt with oats. Satiates very well and is very healthy
have slightly changed my habits compared to before. When I have raisin toast, I now use strawberry jam instead of butter, which helps since it has has no fat.
Butter is prolly better in this case. Sugar is a lot more damaging than most fats, and butter is quite high in good nutrients. But the best replacement would be peanut butter without added sugar and without hardened oils. It's expensive but lasts very long and is very very healthy
I would love to have eggs, but my family is worried that I would take in too much cholesterol (even though I think it's fine).
Eggs don't raise blood cholesterol levels. I don't even know if dietary cholesterol is straight absorbed, sea fruits have cholesterol too but I've never heard of a person that got high cholesterol from shrimps. Saturated and trans fats, sugar and overconsumption of salt raise cholesterol, and just having a bunch of body fat around the waist raises it too. If you're lean, you can eat 2-3 eggs daily, no worries about it.
only have my dumbbells at home as "gym equipment", so I can't do much exercise outside of dumbells and pushups.
That's fine actually. I go to the gym and most of my exercises are body weight and dumbbells these days. Deficit push ups for chest and triceps, romanian deadlifts for hamstrings and glutes, Nordic reverse curls for quads, dragon flags for abs, pull overs for lats, rows and kelso shrugs for upper and mid back...
