Maja blanca is a creamy coconut pudding. In the traditional version, you mix coconut milk with sugar and cornstarch. To make it keto, instead of the cornstarch you can use xantham gum to achieve the same texture. Instead of milk you can use heavy cream since it is lower in carbs and higher in fats.
As for a strict low-carb meal plan that requires very low amount of carbohydrates, they might not be good for people who have liver and kidney issues, pregnant or breastfeeding, or taking medications. Better err on the side of safety for this.
Simplicity is the key to healthy cheap meals. Each low-carb meal should have some good protein, nonstarchy vegetables and plenty of healthy fats. Meals don’t have to be complicated, in fact simple meals are easier to make, cheaper, and will encourage you to cook more often.
Chicken adobo is a traditional dish that uses several herbs and spices. While most are keto-friendly (onion, garlic, chicken, soy sauce, olive oil), it uses brown sugar, which is not allowed on a ketogenic diet. To make it keto-friendly, you can substitute the sugar with a sugar substitute like cooking sucralose or erythritol.
