When I retired I stopped eating high calorie restaurant/cafeteria lunches and took my exercise addiction to another (not all that healthy) level. I started dropping from my target weight to being too slender. To maintain muscle in an old person an extra 1-2% body fat about the 30yo "ideal" is a good idea.
I asked friends, some with similar vices or serious athletic backgrounds, for advice on calorie sources. Here's the current list ...
- Snickers bars
- Chocolate bars
- Whole fat organic Greek yogurt
- Sports drinks
- Peanut butter everything including peanut butter monster trail mix
- Almond butter
- Avocado things
- Baby bel cheese,
- Nuts: macadamia, cashews, Tahini
- Ice cream (cheap)
- Peanut butter granola
