Nonfat milk has fewer calories than whole milk: about 84 kcal per cup (246 g) versus about 149 kcal for whole milk, by our calculation from USDA FoodData Central. We found no official source that says nonfat milk by itself causes weight loss. The NHS says lower-fat milks such as skimmed are a good idea for adults who want less fat.

How many calories and carbs are in nonfat milk?

USDA FoodData Central lists nonfat (skim) milk with added vitamins A and D at 34 kcal, 3.43 g protein, 0.08 g fat and 4.92 g carbohydrate per 100 g. One cup weighs 246 g, so our calculation gives about 84 kcal, 8.4 g protein, 12.1 g carbohydrate and 0.2 g fat per cup.

Is nonfat milk good for weight loss?

The NHS says much of the fat in milk is saturated fat and that eating too much fat can add to excess energy intake. For adults it suggests going for lower-fat milks, such as 1% fat or skimmed, which still keep the nutritional benefits of milk but are lower in fat. That is a calorie swap, not a promise of weight loss. We found no official source stating that nonfat milk makes you lose weight or keeps you full longer.

Nonfat milk vs whole milk: calories per cup

Milk (1 cup) Calories (our calculation) Fat
Nonfat about 84 kcal 0.2 g
Whole (3.25%) about 149 kcal 8.0 g

Cup weights used: 246 g nonfat, 249 g whole, from the USDA portion data. The difference is about 65 kcal per cup.

Who should not switch to nonfat?

The NHS says lower-fat milk should not be the main drink for children under 5 because it lacks enough calories and nutrients for young children. If you are managing weight for a medical reason, ask a doctor or dietitian.

What are the benefits of non fat milk?

The benefits of non fat (skimmed) milk, as the NHS puts it: milk and dairy are great sources of protein and calcium and contain a wide range of vitamins and minerals. It says lower-fat milks such as skimmed still contain the important nutritional benefits of milk but are lower in fat.

The NHS page gives no per-nutrient amounts for skimmed milk, so for numbers use the USDA calories above. We found no official source on non fat milk benefits beyond this.
