How this fits a day of eating
A 1 oz (28g) slice of cheddar is about 113 calories, under 6% of a 2,000 calorie day, with 6g of protein. Cheese is one of the most calorie-dense foods in a typical fridge, and grated cheese in particular is easy to over-pour, so it is a common source of untracked calories.
Grate or slice cheese onto a scale once to calibrate your eye. A loosely packed cup of shredded cheddar weighs about 113g and holds roughly 455 calories, far more than most people expect.
Common questions
How many calories are in a slice of cheddar cheese?
A 1 oz slice of cheddar weighs about 28g and contains roughly 113 calories, 9g of fat, 6g of protein and 180mg of sodium. Thin pre-packaged slices are often closer to 20g, which is about 81 calories. Checking the weight on the pack gives the most accurate figure for your brand.
Can you eat cheddar cheese while losing weight?
Yes, in measured amounts. Cheddar provides protein and calcium, but at about 403 calories per 100g it is very calorie-dense, so small portions add up quickly. Using a strong mature cheddar lets a smaller amount deliver more flavour, and weighing grated cheese helps prevent generous handfuls from adding hundreds of calories.
Is reduced-fat cheddar much lower in calories?
In the US, reduced-fat means at least 25% less fat than the regular version, which typically cuts calories by roughly 20 to 30 percent depending on the brand. Protein usually stays similar or rises slightly. Some people find the texture less satisfying and use more, so compare labels and portions honestly.
