Thanks for your reply. It's mainly my grandmother, and yes, she wants to lose weight, she's just sceptical because she's already seen a dietician, went on diets, exercised, but it didn't really work. As for eating food, that's the funny part, they don't eat that much at all, I've been staying at their place for the last few days, and they eat like mice... but the food that they do eat is extremely high in carbs. They're also in bed asleep by 7pm, but I'm guessing you're talking about fasting? I'm not sure how that would work with them. I don't want them to starve. Which is another reason I like keto, I was struggling to hit my calorie intake because there's only so much grease and fat you can eat before you feel very, very full... I was chugging down thickened cream (basically just fat) to meet it. I'll look into fasting in addition to keto, but I'm not sure if it'll be too much for them at once.
