I have seen a lot of different recommendations for a good ratio of carbs to protein to fat in order to lose weight effectively while maintaining muscle and remaining healthy and satisfying nutritional requirements...

I am currently aiming for 40/40/20. Is this good? It comes out to 205 g carbs, 205 g protein, and 45 g of fat.

I have seen others like 50/30/20, or 35/45/20, etc.

Does anyone have any advice about this? Is 20% fat enough?

I have read consuming too little fat makes a person prone to brain diseases like Alzheimers.

I want to be fit but not at the expense of other aspects of my health..

There is no best ratio. You can lose fat on low carb, high carb, somewhere middle like your 40/40/20, etc. Different macros will give you different advantages for fat loss, but in the end, it all boils down to total calories in vs. calories out. Unless you are competing in say a bodybuilding competition, I prefer sticking with nutrition plan that you are comfortable with and will stick with. Don't stick on a low carb diet just because it gives you some more advantages. I think there are some rules that need to be applied though. For example, I don't think going too low on fat is good. It'll deprive of you of certain important nutrients such as EFAs. 20% fat is fine, as long as you are making sure you get your EFAs.

It depends on you and your goals. There is no right answer.

Unless you are trying to get below like 8% bodyfat, go with any ratio that works for you. Center carbs around breakfast and work outs. Make sure you're getting at least 20-25% of your calories from fats. And you're good to go.

I'm in the "calories in vs. calories out" camp, so long as you're getting the minimums of each macronutrient.

I think success can generally be had at a lot of different ratios.

I've come around to cutting on moderate carbs, high proteins, and somewhere around 35%-40% fat. I enjoy it, I don't have problems with lower carbs (normally somewhere from 75g to 130 g a day) like some do.

I think there is mounting evidence that low to moderate carbs might be slightly more successful for people, but I think that may be due to people who eat higher carbs making bad choices and not timing them right.

I also think different people will have better success on different types of plans. So experiment.

I agree with KT. The macro ratio (esp. carbs) is more important at lower body fat levels, but almost meaningless (granted you are having moderate amounts of every macro) when you are carrying a lot of fat.

Calories in vs. calories out, in my opinion.

I think we react differently. What works for one of us won't for somebody else.
