There are 56 calories in a 1oz serving of homemade beef jerky. Calorie breakdown: 18% fat, 2% carbs, 80% protein.
Jerky is made from lean cuts of beef that are cooked at low heat for a long time, so very little fat makes it into the end product. On the other hand, meat sticks, encased like sausage, have 8 to 13 grams of fat, including 3 to 5 grams of saturated fat. The sticks also have about twice the calories of the jerkies.
