GDAWG15 like many others is prepping his meals while counting his macros, not just the number of calories, based on his specific stats, performance, goals, etc. So by asking how to pick up extra clean calories, you're being a little vague. It's an effective and more precise approach to pre-plan your meals for the week according to your macros, and sure you may have one day where you can cheat a little (nobody's perfect), but this way you won't have to wing it and just hope for the best or that you'll look your best by just guessing.
For example, you could eat avocado or watermelon, either would be considered clean calories. But if you've already maxed out on your daily fat intake but still could spare some carbs, the watermelon would be a better choice. But it really depends on you, your macros and your goals. I usually pre-plan, but I like many others in Houston I just got wrecked by hurricane Harvey. My house is still being rebuilt so you could easily say it's not as easy to pre-plan as it was before, and to give you an example... if it's nearing the end of the day and I'm trying to limit carbs and fat intake and get some more protein in before bed, I might go for some fat free plain greek yogurt, low fat cottage cheese and a protein shake with skim milk (excellent sources of protein, low in fat and carbs).
What you eat is just as important as how you train and rest (pct as well if you cycle), then comes drugs and lastly supplements. Not the other way around. Just because you shoot a gram of test a week and take the most expensive creatine and protein powder on the market, that does not mean you can cheat on the diet/training/rest departments and expect to look your best, or even halfway decent to be honest.
Do some research buddy. Best of luck.
And doughnuts... my god... those touch the soul...
