Tips please for logging food when cooking from scratch

First, I'd ask how you're using the scale. There are shortcuts. Here are a few examples:

• Assembling a salad in a bowl, a stew in a pan, sandwich on a plate? Put the bowl/pan/plate on the scale, zero, add an ingredient, note the weight, zero, add the next ingredient, note the weight . . . .
• Using something from a carton or jar, or cutting a slice from a hunk of cheese? Put the container or chunk on the scale, zero, take out portion, note the negative value (it's the amount you took out).
• Eating a whole apple, banana, un-hulled strawberries, corn on the cob? Weigh the ready-to-eat food, eat the yummy parts, weigh the core/hulls/peel, subtract & note.
• I like to keep a few clean plastic yogurt-tub lids around to weigh small items, like a handful of nuts or chopped hardboiled eggs or something. Drop the lid on the scale, zero, add item, note weight, eat or use - just a quick rinse of the lid under the faucet & you're done.

Personally, I find it easier to note these things on paper while I'm cooking, log the whole meal in MFP later. Sometimes I log in MFP only once a day, just using that scribbled list. (I like to use random junk mail envelopes or other paper scraps I'll be recycling for notes, but YMMV.)

Second, if you have things that you make sort of the same way frequently, such as a sandwich or Ceaser-like salad, save those things as an MFP "meal". When you pick a meal to log, it brings the individual items into your diary (not just a one-liner like when you use an MFP recipe). It's easy to adjust the quantity or delete/add items right in your diary then. Some people only worry about the higher-calorie items. Personally, I find it easier to autopilot log everything - for me, that takes up less brain bandwidth, leads to fewer errors.

I'm not remotely disciplined, but after getting my recent/frequent foods populated, and some basic meals set up, plus keeping my scale handy on the counter all the time, it rarely takes me even as much as 10 minutes a day to log my eating. To me, that's a small price to pay to have gotten from class 1 obese to a healthy weight in less than a year, and having stayed at a healthy weight for 7 years since. I feel so much better, have less pain/discomfort, and other quality of life improvements as a result . . . for way less than 10 minutes a day. That's a win, in my book.

P.S. I cook at home from scratch the overwhelming majority of meals. Yesterday, my diary had 32 food items. It was a pretty typical day.
