Pear: Calories, Protein and How It Fits Into Your Diet

Pears get skipped on a lot of cutting diets because they taste sweet, and then the same person eats three biscuits with coffee without blinking. The numbers say otherwise: a medium pear of about 180 g gives you roughly 103 calories, 5.5 g of fiber and less than a gram of protein. Here is exactly what you get and how to fit it into your day, whether you are cutting or bulking.

Calories and macros per 100 g

These figures are for raw pear with the skin on, averaged across common varieties (Williams, Bosc, Conference):

• 57 calories
• 15.2 g carbohydrate, of which about 9.8 g natural sugars (fructose, glucose, sorbitol)
• 3.1 g fiber
• 0.36 g protein
• 0.14 g fat
• about 84 g water and 116 mg potassium

Per piece: a small 150 g pear is about 85 calories, a medium 180 g pear about 103 calories, and a large 230 g pear about 130 calories. That is a 45-calorie spread between the smallest and largest pear in the same bag, which is more than most people assume when they eyeball portions.

The skin carries a meaningful share of the fiber and polyphenols. Peel the pear and you lose roughly a quarter of the fiber. Unless your gut reacts badly to it, eat it with the skin and just wash it properly.

Protein: honestly, negligible

A medium pear has about 0.65 g of protein. If you lift and weigh 80 kg, your daily target is around 1.6 to 2.2 g per kilogram of bodyweight, so 128 to 176 g of protein per day. One pear covers less than half a percent of that. A pear is not a protein food and there is no point treating it as one; it is a source of water, fiber, potassium and vitamin C (about 7 mg per piece).

If you want the pear to be part of a meal that actually holds you for three or four hours, pair it with a protein source:

• pear + 200 g of 0 % Greek yogurt: about 220 calories and 21 g protein
• pear + 150 g low-fat cottage cheese: about 215 calories and 19 g protein
• pear + 2 whole eggs: about 255 calories and 13 g protein
• pear + 25 g almonds: about 250 calories and 6 g protein, plus 12 g fat

Fiber, sugar and blood glucose

The 5.5 g of fiber in a medium pear is roughly a fifth of the 25 to 30 g daily target. The glycemic index of pear is around 38 and the glycemic load per piece is about 4, which is low. In practice that means one pear will not produce the blood sugar spike that fruit generally gets blamed for.

Part of the sugar in a pear is sorbitol, a sugar alcohol that absorbs slowly. That is why pears can have a mild laxative effect, and why 300 g of pear in one sitting can cause bloating and cramping in people sensitive to FODMAPs (for example with irritable bowel syndrome). If that is you, take 100 to 150 g per meal instead of two large pears at once.

Fitting it into a calorie deficit

Example: an 85 kg man, maintenance around 2,700 calories, deficit set at 2,200. Two pears a day is 200 calories, about 9 % of the budget, and that is perfectly workable as long as the rest of the day hits your protein. The problem starts when fruit gets eaten on top of everything else instead of in place of something.

1. Keep fruit to 2 or 3 servings a day; one serving is roughly 150 g.
2. Weigh your fruit for the first week or two. Eyeballing is off by 50 to 80 calories per piece, which is over 300 calories a week.
3. Do not drink it. A 250 ml glass of pear juice is 120 to 140 calories with almost no fiber, and it will not fill you like the whole fruit.
4. Eaten 60 to 90 minutes before training, one pear supplies about 25 g of carbohydrate, enough for a 45 to 60 minute strength session without sitting heavy in your stomach.
5. After training a pear is fine as an extra, but the meal is built on 30 to 40 g of protein, not on fruit.
6. Dried pears are a different food: 100 g is about 260 calories, so a 40 g handful already costs you 105 calories.

Pears do not ruin a diet. Unweighed food and three meals a day with under 20 g of protein each do.

When to see a doctor

A pear is food, not medicine, but digestive reactions can flag something else. Get checked if you:

• have bloating, cramping or diarrhea lasting more than 3 to 4 weeks regardless of what you eat;
• feel itching in your lips, tongue or throat within 30 minutes of eating fresh pear, which can be oral allergy syndrome linked to birch pollen allergy;
• notice blood in your stool or lose 5 % of your bodyweight in three months without trying;
• have diabetes or prediabetes and do not know how much fruit suits you, in which case a glucose reading 90 minutes after a meal gives a concrete answer;
• have kidney disease or medication that limits your potassium intake.

The short version

• 100 g of pear is 57 calories; a medium 180 g pear is about 103 calories.
• Protein is 0.65 g per piece, so it is negligible; pair it with yogurt, cottage cheese or eggs.
• 5.5 g of fiber and a low glycemic index of 38 give good fullness per calorie.
• Two pears a day fit into most diets; eat them with the skin and weigh them for the first couple of weeks.
• Digestive symptoms lasting over a month, or a reaction in your mouth, belong with a doctor rather than a search engine.
