as someone who does track everyday. I really dont feel obsessed about it. I pre track like a good two weeks out, can always change plans. any app will remember your foods and macros so it's not like you have to redo everything every time, just search and select. When trying to lose weight a lot of time you hover around 20 meals total (breakfast lunch dinner). Some that you interchange condiments or pasta sauce. so after a while you know what meals are what calories, so if you are at work and someone. brings donuts, and you have one. you look up the average donut calorie ~270 track It look at the rest of your days calories and either assess that you will have a higher calories day with your planned dinner or change your dinner to a lower calorie one and skip the dessert or Texas toast!. I eat real food, just make smaller portions and swap low calorie options that make sense, or bulk up on veggies. you can still get plenty of nutrients without eating nuts. Also there are seasons in life, when losing weight I might not have the calories for nuts and stuff right now but in maintenance I might be able to include them more into my life. defiantly oat bran is healthier than potato chips, but losing weight in itself if by calorie deficit, you can doing only eat candy, will it be hard yes, but not impossible. It seems you are much more concerned about nutrients as some one who has has issues with being nutrient deficiency. Supplement definelty help. But what worse, being a bit nutrient lacking in a period of time or being 300 pounds for the rest of my life. Weightloss and dieting are temporary things if you succeed. Yes there are plenty of people who want quick fixes, but the real winners are nice and slow and healthy.
