"Half of an avocado calories" is one of the most-searched food halves - and it is not really about arithmetic. People search halves because halves are decisions: you saved the other half with the pit in it, you split a bagel when the bakery sold them in twos, you boxed half the burrito for tomorrow. The table below prices the twelve halves people actually eat, using whole-food reference amounts consistent with USDA FoodData Central entries.
Bottom line: half a medium avocado is about 120 kcal and half a medium banana about 53; half a large chicken breast lands near 140 with roughly 26 g of protein; half a plain medium bagel runs about 145 kcal of mostly starch; half a cheese pizza slice is around 140. The pattern worth noticing: on whole foods the half is a genuine portion; on bakery and restaurant items the half is often still a full serving's worth of energy.
The honest part: every number here is a reference-value approximation, not a measurement - avocados alone double between small and large, and a bakery bagel can be twice the chain-store standard. Treat the table as the center of a range that runs about plus or minus 20 percent, and treat your own kitchen scale as the truth when a number actually matters.
How to use
- Find the food, read the half: the table lists the common whole reference (medium fruit, standard slice, typical serving) and what one half of it costs in calories and protein.
- Mind the reference, not just the row: a 'medium' avocado is about 150 g before the pit and skin; a 'large' one is closer to 200 g, and the half moves with it.
- For split meals, log the half you ate and store the other half deliberately - the storage notes below keep the second half worth eating tomorrow.
Frequently asked questions
How many calories are in half of an avocado?
About 120 kcal for half of a medium avocado (roughly 68 g of edible flesh), with about 1.5 g of protein and most of the calories from monounsaturated fat. Avocados swing harder than most foods - a small one halves to about 80 kcal and a large one past 160 - so if the number matters, weigh the flesh: about 1.6 kcal per gram.
How many calories are in half of a banana?
About 53 kcal for half of a medium banana (about 118 g whole, 9 inches or so), with roughly 0.65 g of protein. Bananas are among the most standardized foods in the reference tables, which is why the half is such a clean number - and why the 'half a banana in a smoothie' habit is a genuine 50-kcal lever.
How many calories and how much protein in half a chicken breast?
Half of a large cooked, skinless chicken breast (about 88 g of meat) is roughly 145 kcal and about 27 g of protein - one of the best protein-per-calorie ratios in the table. Cooking method moves it: add about 40 kcal per half for pan oil, and skin roughly doubles the fat line.
How many calories are in half of a bagel?
About 145 kcal for half of a plain medium bagel (a standard 105 g bagel runs near 290), almost all of it starch with about 5-6 g of protein. Two honest warnings live in this row: bakery bagels routinely run 130-150 g, so the 'half' can carry a full 290; and a flavored or sweetened bagel shifts the number up before you count the cream cheese.
What's the best way to store the half I didn't eat?
Avocado: keep the pit in the saved half, brush or squeeze lemon juice on the cut, wrap tight, and refrigerate - you buy a day, not forever. Banana: peel, wrap the cut end, refrigerate (the skin blackens, the fruit doesn't). Pizza and sandwiches: box and refrigerate within two hours; reheat pizza in a dry pan, not the microwave, to keep the crust from going rubbery. Bagels and croissants: they freeze well halved, toasted from frozen.
Is eating half now and half later actually a good strategy?
It is one of the few portion strategies that survives contact with real hunger, because it uses the end of the meal - not willpower at the beginning - as the control point. The arithmetic is the simple half: two halves of a 940-kcal burrito are two 470-kcal meals, which is a more honest lunch than eating all 940 and calling it one. The table's job is to make the second half a known number before you order.
