The chef's caveat

One handful is not one serving

A "handful" of nuts is usually 30–40g, not the "1 oz (28g)" on the label. If you snack straight from the bag, expect to eat 1.5–2 servings without noticing. Weigh once to calibrate your eye.

Common questions

The stuff people actually ask.

How many calories in oz of nuts?

About 140 calories, with roughly 2.3g of protein. oz weighs about 28g. Use the slider above for any other portion.

Are nuts good for weight loss despite the calories?

Studies say yes, actually — people who add nuts to their diet without cutting other calories do not gain weight proportionally. Best theories: chewing time, satiety, and about 10–20% of the fat calories are not fully absorbed.

Is nuts actually healthy, or is that marketing?

By the numbers on this page: dense in unsaturated fat, fiber, and micronutrients — the "high calorie ≠ unhealthy" case in food form.
