Coming in under target, need healthy snacks!

If you are under your calorie goal basically eat more. It doesn't really matter what, if it fits then eat it. It doesn't have to be what you consider healthy either, food is food, although try and hit your macros.

The one item to be aware of is if you are logging your exercise and eating the calories back. In that case its easy to over estimate, and end up with a very small, or non existent deficit.

Trust your gut - coming in way under is bad, especially for a guy since you need more calories than us ladies.

Technically, you can eat whatever you like. Some very successful people on here eat ice cream or gelato on a regular basis because as long as it fits your calories/macros, it's all good. But if you prefer to go with more real foods (healthy is subjective) how about nuts, seeds, dried fruit (or put those three together for yummy trail mix), peanut butter with apple or carrots or banana, eggs, full fat yogurt or cottage cheese, avocado, cheese and fruit...

That's all I've got off the top of my head. The other option is bulking up meals by adding oils, sauces and some of the above ingredients. Skip the diet foods, you have plenty of calories and there's nothing wrong with full fat...unless, of course, you have a heart health issue.

ETA - just saw that you don't log calories. In that case, you DEFINITELY need to eat more. I get that it's hard to estimate but you can't just skip that part of the program completely. One option to make it a bit simpler is to up your activity level. Say you have a desk job so you're sedentary but you work out a few times a week so that would make you at least lightly active...and you can set your activity level as such. That way you don't have to worry about logging exercise as the calories are already factored into your daily goal.

edited again - holy typos Batman!

There are some snacks that are both healthy and have a bit of calories. Peanut butter/other nut butters, for instance. I use avocado for a snack sometimes. And I can eat about a mountain of Greek yogurt - tasty, and tons of protein.

I like a boiled egg, or a yogurt (I know some people don't like yogurt). Some vegetable chips (actual vegetables, crisped in the oven) a salad wrap or similar. But I'll eat a bowl of ice-cream if it will fit in my calories.

You can also save those calories for a ones a week "nice" dinner. If there is a food you avoid because it's a little calorie dense you can use the calories you don't eat for one splurge meal.

When I find myself coming in with low numbers, I make an insanely awesome protein shake. I'm talking chocolate whey powder +banana +peanut butter +milk or vanilla whey powder +blueberries+ banana+ milk kind of deals. How far under I might be and how much protein I need to meet my goal for that day factor in, too, but those are my typical go-to shakes.

ETA: I also like vanilla ice cream + granola + dried fruit (you could always use yogurt, if you don't want to have ice cream!). There are plenty of nutrient dense foods out there: many different kinds of nuts, avocado, fruits, etc.

If I had calories to burn I'd be eating CHEESE, nuts, sunflower seeds, olives, and maybe follow that up with some CHEESE!

Yummy almond butter on ray crackers, even better than pb. Also like prunes and venison biltong (jerky).
