Variations
Raw (fresh)
518 kcal per 100 g — raw fresh pork belly as per USDA data. The default reference form with 53 g fat, 9.34 g protein, and 37% water content.
Roasted (crispy skin)
~500 kcal per 100 g (estimate). Slow-roasted pork belly with crispy skin. Some fat renders out during cooking, but water also evaporates, keeping the calorie density similar to raw. The texture transforms from soft to crispy on the outside and tender inside.
Braised (stewed)
~430 kcal per 100 g (estimate). Braised or stewed pork belly — more fat melts away into the cooking liquid compared to roasting. Common in Asian cuisine (red-braised, soy-ginger, dong po rou). Lower calorie density than raw or roasted because more fat is lost during slow cooking.
Dietary Perspectives
For Weight Loss
Not suitable for weight loss — 518 kcal per 100 g is one of the highest among meats. A serving (85 g) has 440 kcal with only 7.9 g protein. The protein-to-calorie ratio is terrible: you'd need 4 servings (1,760 kcal) just to get 32 g protein. Choose pork tenderloin (143 kcal, 26 g protein per 100 g) or chicken breast instead.
For Athletic Performance
Not recommended for athletes — very low protein (9.34 g) at extreme calories (518 kcal per 100 g). The 53 g of fat provides no advantage for recovery or performance. Occasional treat only. For pork protein, choose tenderloin (26 g protein at 143 kcal per 100 g) or lean pork chops.
For Keto
One of the most keto-friendly meats available — zero carbs with extreme fat (53 g per 100 g). The fat-to-protein ratio is ideal for hitting keto fat targets. A slice (30 g) has 155 kcal, 2.8 g protein, 15.9 g fat, 0 g carbs. Slow roast for crispy skin, braise in soy sauce and ginger, or slice thin and pan-fry. Low sodium (32 mg per 100 g) is a bonus on keto where electrolyte balance matters.
