Weetabix calories come to 130 for 2 biscuits (35 g) and 371 per 100 g. Look at the fiber first. That serving brings 4 g of fiber alongside only 2 g of sugars and 1 g of fat, so nearly all of the energy comes from whole-grain carbohydrate rather than added fat or sweeteners.

Two biscuits are a 130-calorie base, and the count adds up fast
The standard serving is 2 biscuits (35 g) for 130 calories, which is 6% of a 2,000-calorie daily value. Because Weetabix comes as fixed biscuits rather than loose flakes, portions are easier to keep steady than with most cereals. You count biscuits instead of guessing at a pour.
The total climbs quickly once you add biscuits. Four biscuits (70 g) come to 260 calories, six (105 g) reach 390, and ten (175 g) hit 649. If you measure by volume, 1 cup (57 g) works out to 211 calories, or 11% of the daily value, which is noticeably more than the two-biscuit serving most people picture.
These numbers are for the dry cereal only. Milk, sugar, honey or fruit go on top of them, so log what you pour as a separate item. A bowl that starts at 130 calories can end up much higher depending on what goes on it.
Carbs supply 82% of the calories, and fat barely registers
Weetabix is a carbohydrate food. Carbs supply 82% of its calories, protein 12% and fat just 6%. Per 100 g that means 81.5 g of carbohydrate, 11.4 g of protein and 2.9 g of fat, of which only 0.5 g is saturated.
What sets it apart is the quality of those carbs. Of the 81.5 g, 11.4 g is fiber and just 5.7 g is sugars per 100 g. In the 2 biscuits serving that translates to 4 g of fiber against 2 g of sugars, a ratio that sweetened flakes rarely match.
Protein is modest. The 4 g in a two-biscuit serving covers 8% of the daily value, and even 1 cup (57 g) delivers only 6.5 g. Weetabix works as a whole-grain carb base, not as a protein source, so it needs company to make a filling breakfast.
Fiber is the standout row; sodium is moderate
Fiber is the row worth celebrating. With 4 g in 2 biscuits and 6.5 g in 1 cup, Weetabix puts a real dent in the 28 g daily value used on nutrition labels. Cholesterol is 0 mg, and potassium reaches 429 mg per 100 g.
Sodium deserves a glance rather than alarm. Two biscuits carry 130 mg, which is 6% of the 2,300 mg daily value, and 100 g carries 371 mg, or 16%. That is lower than many cold cereals, but it is not zero the way plain oats nearly are.
If you watch sodium, the bigger risk is portion creep. Ten biscuits (175 g) carry 649 mg, so the same habit that inflates calories also inflates salt. Sticking near the two- or four-biscuit mark keeps both rows in check.
Weetabix needs protein on the side to keep you full
Low fat and moderate protein mean Weetabix alone digests without much staying power. Pairing it with a protein-rich addition such as milk, Greek yogurt or eggs on the side turns a 130-calorie base into a breakfast that holds you longer. Fruit adds volume and sweetness without the need for spooned sugar.
Because the biscuits are so consistent, Weetabix is one of the easier breakfasts to track. Count the biscuits, then log the milk and toppings separately. BodyPal can log the bowl from a photo, which helps when the toppings change from day to day.
In a day of eating, two biscuits at 6% of daily calories leave plenty of room elsewhere. The cereal itself is rarely the problem; heavy pours of sugar or full-fat extras are where a light breakfast quietly turns into a large one.
How does Weetabix compare?
Here is how Weetabix stacks up against Cheerios, frosted flakes and rolled oats, per 100 g and per usual serving.
Verdict: For the least sodium pick rolled oats at 6 mg per 100 g; among ready-to-eat cereals Weetabix wins with 371 mg against 497 mg for Cheerios and 451 mg for frosted flakes, and it has far more protein than frosted flakes at 11.4 g versus 4.3 g. Cheerios looks lightest per bowl at 104 calories, but only because its 1 cup weighs just 28 g, so compare by weight before you choose.
