How this fits a day of eating
A 170g pot of plain nonfat Greek yogurt is about 100 calories, 5% of a 2,000 calorie day, with 17g of protein. That protein-to-calorie ratio rivals chicken breast, which makes it one of the most useful breakfast and snack foods when you are trying to eat more protein in a deficit.
Flavoured and full-fat versions are very different foods. Whole-milk plain Greek yogurt is about 97 calories per 100g, and sweetened fruit versions often contain two to three times the sugar of plain.
Common questions
How many calories are in Greek yogurt?
Plain nonfat Greek yogurt has about 59 calories per 100g, with 10g of protein and under 4g of carbohydrate. A standard 170g pot comes to roughly 100 calories and 17g of protein. Low-fat and whole-milk versions are higher in calories, and sweetened flavours add sugar, so check the specific label.
Is Greek yogurt good for weight loss?
Plain nonfat Greek yogurt is one of the most protein-dense dairy foods, providing about 17g of protein for 100 calories in a 170g pot. Protein helps with fullness and muscle retention in a calorie deficit. Choosing plain yogurt and adding fruit yourself keeps sugar and calories lower than most flavoured options.
What is the difference between Greek yogurt and regular yogurt?
Greek yogurt is strained to remove much of the liquid whey, which makes it thicker and concentrates the protein. Plain nonfat Greek yogurt has about 10g of protein per 100g, while regular plain nonfat yogurt has closer to 6g. Straining also lowers the carbohydrate content, since some lactose leaves with the whey.
