Too much protein can actually be harmful to our health (renal problems including very painful kidney stones, amongst others).
The SP recommendations, altho' not set in stone, are a very good middle of the road ratio to aim for. I am generally a little higher in my carbs (wholegrains and fruit/veges mainly) and hovering around 56-59%, a wee bit lower in my fat - generally around 20-22% (my dietitian wants me around 20% which for me is good because I am not keen on much fat, even from the healthy sources.) I do struggle sometimes to get the minimum (60g) protein in, but as I have a regular snack before bed, I often use that time for tweaking.
The thing is about the Insanity Diet Plan, from my understand it is saying you can loose 11kg (about 24lb) in 3 weeks. That can be downright dangerous, and actually cause you to regain loads and just as quickly, when you reach your goal ....... if in fact you reach it! Theses sorts of things (IMHO) ARE insane and best left alone!
Good luck with whatever you choose - hopefully the healthier way :-)
