You are right that there are many types of low carb diets. Some are zero carbs others are perhaps 50g or 100g. Some are using a 4:1 fat to protein ratio and the more “mainstream” low carb diets are using a 1:1 ratio. Some are calories restricted, others are not. The one I have chosen to use is the 50g carbs and a 1:1 fat:protein with a 500kcal deficit to loose weight. It works great. Also be aware that there are many high carb diets out there. Most of them are extremely dangerous. Leading to Type 2 diabetics, blindness, amputations, fatty liver, hypoglycaemia, heart problems and (ultimately) an early death. However some high carb diets are fine if done right. So I think we can agree that we need to be very specific when we talk about diets and emphasise what is needed for it to be actually healthy.
