Banana · raw

The banana is lifters' favourite fruit: 20 g of easily available carbs and potassium per 100 g (94 kcal). It provides quick energy, handy before training for a boost, or after to help refill glycogen.

Portable, digestible and cheap, it ripens at room temperature: the riper it is, the faster its carbs are absorbed.

On its own as a training snack, sliced into a bowl of oats or skyr, or blended in a smoothie with whey and peanut butter: it is one of the simplest ways to add carbs to a bulking snack.

Its natural sweetness pleasantly sweetens a porridge or fromage blanc without added sugar — handy to make 'cutting' meals more enjoyable.

A banana is moderately caloric and perfectly compatible with cutting if it fits your calories. It is not the fruit that causes weight gain, but your daily calorie total. Its fibre (2.6 g) and potassium make it a healthy snack versus ultra-processed products.

Ripeness changes the profile: a well-ripened banana (spotty skin) has faster-absorbed carbs — handy right before or after a session. A slightly green banana contains more resistant starch, digested more slowly, with a slightly more filling effect.

In practice, the calorie difference is small: choose mainly by taste and timing. Well-ripened for energy around training, a bit firmer for a snack that keeps you full.

Per 100 g of flesh, a banana provides 94 kcal, 1.1 g protein, 20 g carbs, 0.3 g fat and 2.6 g fibre. But nobody weighs 100 g of flesh: a small peeled banana is about 90 g (85 kcal, 18 g carbs), a medium one about 120 g (113 kcal, 24 g carbs, 3 g fibre) and a large one about 150 g (141 kcal, 30 g carbs). So remember that a medium banana is roughly 25 g of carbs.

Mind the peel: the values refer to the peeled flesh. If you weigh the whole fruit with its skin, about a third of the displayed weight is not eaten. For accurate tracking in your app, weigh the flesh, or simply log 'one medium banana' and keep that convention over time so your data stays comparable.

On the protein side, a banana barely counts: 1 to 2 g per fruit. It plays the role of a comfort carb, not a protein source. You should therefore always pair it with skyr, fromage blanc, eggs or whey to build a snack consistent with a muscle-gain goal.

A medium banana provides about 25 g of digestible carbs and little fat or heavy fibre, making it a well-tolerated pre-workout snack. In practice, eat it 30 to 60 minutes before training if your stomach is sensitive, or up to 15-20 minutes before if you tolerate it well. More than two hours out, it mainly serves to top up a meal.

For a standard one-hour lifting session you do not need to load up on carbs: if your last meal was less than three or four hours ago, the banana is a bonus, not a requirement. It becomes truly useful when you train early in the morning fasted, after a long day without eating, or for a long, intense session where you want to keep performance up to the last set.

Always test under real conditions: some people feel heavy with a banana right before effort, others do not. Note your feeling in your training log and adjust the timing. The fruit is the same, but digestive tolerance is individual.

After training, muscles are more receptive to carbs. One to two bananas paired with a protein source supply 25 to 50 g of easily digested carbs, a good starting point to refill glycogen without weighing down the next meal. The classic combo: a banana blended with 30 g of whey and milk in a shaker.

That said, the urgency is often overestimated. If you eat a proper meal within two or three hours after the session, the banana is just a plus. It really makes sense when the meal is far off, when you train several times a day or when you lack appetite and want something light.

First mistake: counting it as a protein source. With 1.1 g per 100 g, it barely helps you reach your protein target. Second mistake: eating several alone on an empty stomach, then feeling an energy dip an hour later because the sugar arrived quickly without protein or fat to temper it.

Third mistake: forgetting to log it because 'it is just a fruit'. Three bananas a day represent about 340 kcal and 72 g of carbs: not negligible when cutting. Fourth mistake: demonising it because of its sugar. The carbs in a whole fruit come with fibre, potassium and vitamin B6, which is nothing like candy.

When bulking, the banana is an easy tool: it lets you add 100 to 150 kcal and 25 to 30 g of carbs to a shake or a bowl of oats with no chewing or cooking effort. Two bananas in a homemade mass shake with milk and oats push your calorie total up when appetite is limited.

When cutting, keep it in your plan but frame the frequency: one medium banana around training or to sweeten a fromage blanc is enough. Rather than a big banana alone, use half a mashed banana to flavour your porridge. You get the sweetness for about 55 kcal, which helps you stick with the diet without frustration.

Choose firm bananas, without soft brown patches, with an intact stem. Let them ripen at room temperature, away from other fruit if you want to slow the process. To keep them longer, separate the bananas from the bunch and wrap the stem in cling film: it releases less ethylene and ripening slows down.

The skin darkens in the fridge, but the flesh stays edible: it is only cosmetic. To avoid waste, peel very ripe bananas, slice them and freeze them flat. They then blend in seconds with milk or skyr into a creamy ice-cream-like texture with no added sugar, very handy for a cutting-phase dessert.

Compared with an apple (about 14 g of carbs per 100 g), the banana is more energy-dense and more filling in the short term, but less watery. Compared with berries, it contains more carbs and calories: blueberries or strawberries let you eat a bigger volume for fewer calories. Compared with white rice or pasta, the banana needs no cooking, which is its convenience advantage.

The right choice depends on context. Around training, the banana wins for speed and potassium. During the day when cutting, berries or an apple leave more calorie room. Rotating fruits is the best strategy: each provides different vitamins and antioxidants.

Banana is generally well tolerated. It contains small amounts of fructans and sorbitol, and a very green banana may ferment in people with a sensitive gut. A latex allergy can come with cross-reactivity to banana: if you get an itchy mouth or swelling, seek medical advice. If you are on treatment for blood pressure or kidneys, discuss your potassium intake with your doctor.

Quick meal ideas: wholewheat toast with peanut butter and banana slices, a bowl of skyr with banana and oats, oat-banana-egg pancakes pan-cooked without added fat, or mashed banana mixed with fromage blanc and cinnamon. Each idea stays simple, cheap and easy to weigh in your tracking.
