Is low-fat milk good for weight loss?
We found no official source from the NIH, NHS or USDA that states low-fat milk leads to weight loss, so we do not claim it. What we can show is the calorie difference from USDA FoodData Central.
How many calories are in low-fat vs whole milk?
USDA SR Legacy lists 42 kcal per 100 g for 1% milk and 61 kcal per 100 g for whole milk (3.25% fat). A cup weighs 244 g in both entries.
| Milk (USDA) | Per 100 g | Per cup, 244 g (our calculation) |
|---|---|---|
| 1% lowfat | 42 kcal, 0.97 g fat | about 103 kcal |
| Whole, 3.25% | 61 kcal, 3.25 g fat | about 149 kcal |
The gap is about 46 kcal per cup (our calculation). Whether that matters depends on the rest of your diet.
Do both have the same protein?
Per 100 g, USDA lists 3.37 g protein in 1% milk and 3.15 g in whole milk, so protein is about the same.
What should you do?
Weight change depends on total calories over time, not one drink. If you want to lose weight, ask a doctor or registered dietitian. Current federal dietary advice on milk fat has changed between editions, and we did not open it, so we do not summarize it here.
