Full Fat vs Light Coconut Milk: What Is the Difference?

Coconut milk comes in two very different forms that are easy to confuse: full fat canned coconut milk and light canned coconut milk. Both are used primarily for cooking rather than drinking, and choosing the wrong one can significantly affect both the calorie content and the texture of your dish. Here is a clear breakdown of the differences.

Note: This Is About Canned Coconut Milk

This post focuses on canned coconut milk — the thick, creamy product used in cooking — not carton coconut milk which is the diluted drink-ready product sold in the dairy aisle. These are fundamentally different products and the calorie comparison is very different. Canned coconut milk in both full fat and light varieties is primarily a cooking ingredient.

Calories: Light Is Significantly Lower

Full fat canned coconut milk contains approximately 445 calories per cup — making it one of the most calorie-dense liquid ingredients used in cooking. Light coconut milk contains approximately 125–150 calories per cup — about one third of the full fat version. For calorie-conscious cooks, the swap from full fat to light coconut milk is one of the most impactful single substitutions available in Asian and tropical cooking.

Fat Content

Full fat coconut milk contains around 48g of fat per cup, the vast majority of which is saturated fat in the form of MCTs. Light coconut milk contains around 10–13g of fat per cup. The texture difference this creates is significant — full fat coconut milk is thick and creamy, while light coconut milk is thinner and more watery.

Effect on Cooking

Full fat coconut milk is the standard choice for curries, soups, and desserts where a rich, creamy texture is essential. Thai curries, laksa, coconut rice, and panna cotta all rely on full fat coconut milk for their characteristic richness. Substituting light coconut milk in these dishes produces a noticeably thinner, less flavourful result.

Light coconut milk works well in dishes where coconut flavour is desired but a lighter texture is acceptable — smoothies, lighter soups, marinades, and some baked goods. It is also a reasonable substitute when you want to reduce calories in a recipe without eliminating coconut flavour entirely.

Which Should You Choose?

Choose full fat if: you are making a traditional curry, creamy soup, coconut-based dessert, or any dish where texture and richness are important to the result.

Choose light if: you are calorie-conscious, making a dish where a lighter texture is acceptable, or using coconut milk as a background flavour rather than a primary ingredient.
