I'm actually getting over 50% of my calories from fat, some days as high as 80%. The rest is about an even split between carbs/protein. I'm not really strict with my macros as long as I get a lot of fat. Sometimes I'll even do <20g carbs/day for a week, then bring it back up to 40% with fruit then drop it back down. I like to vary it.
Also IMO the best way is to eat the same things each day. If you know that x eggs, x bacon, x oz of beef, x cups of rice, x amount of nuts, x amount of broccoli = 1400 calories, and that's your target, eat that same meal every day that week, and then next week use a different plan that gives you 1400. This way it's varied week to week, but during the week there is no stress over counting, preparing, etcetc.
Just my approach.
