14 Snacks Under 100 Calories That Fill You Up and Slim You Down

These snacks won’t undermine your weight loss efforts.

Unhealthy, high-calorie snacks can undermine even the most controlled weight loss regimen—but not all snacks are created equal. "When snacking is done correctly, it can give you a boost of energy between meals, help meet nutrient needs for the day, and help keep hunger at bay to prevent overeating at the next meal," says the Mayo Clinic. "And managing your hunger can help you maintain a healthy weight and reach weight loss goals." Here are 14 snacks that are not only good for you but will help you lose weight as part of a healthy, balanced diet.



Full of healthy fats and protein, almonds are a great choice for a healthy snack on the go. They don't need to be refrigerated-simply carry them in your bag or car. Some almonds are sold in 100-calorie packs, making them even easier to enjoy while sticking to the calorie limit.

That's a combination that's hard to beat."

Greek Yogurt


Packed full of healthy fats and probiotics, Greek yogurt has twice as much protein as regular yogurt and is a perfect snack to get you through to lunch or dinner. Watch out for any added sugars as that will up the calorie count considerably.

Cottage Cheese

Low-fat and high-protein, cottage cheese is a filling snack with nutrients such as B12 and calcium. "Look for live and active probiotic cultures in the list of ingredients," clinical dietitian Carly Zimmer tells OSF Healthcare. "It usually has parentheses that say what kind of cultures were added, like lactobacillus. Not all brands have those live and active cultures."

Crunchy and delicious, raw carrots are high-volume and full of fiber. "Since 1/2 cup of carrots only have 41 calories, they can actually help you feel fuller longer and in turn, decrease the amount of calories you eat," Anna Taylor, MS, RD, LD, CDE, tells the Cleveland Clinic. "If you're looking to lose weight, try adding some carrots into your food rotation."

The fiber and healthy fats in avocado make it an ideal snack. Avocados are also low in sugar and packed with more potassium than a banana. "A whole avocado has under 1.5 grams of sugar, while one medium apple, by comparison, has about 19 grams," Julia Zumpano, RD, LD, tells the Cleveland Clinic.

Lean deli turkey is a good source of protein and can make for a filling snack. Deli meat fresh from the counter is the best option, experts say. "That is not always feasible for people … but if you can and you're able to choose organic sources, something like Applegate Turkey that's going to have minimal added ingredients, minimal preservatives, that's going to be a healthier choice," registered dietitian nutritionist Danielle Crumble Smith tells USA Today.
