The best advice i can give anyone to keto diet's and recipes is to either go to bodybuilding.com and click on the forums section. If you do some searching under there you will find the nutrition section and at last there will be a shit load of recipes and advice from fellow people on the forums. i actually think that under the nutrition section there is a keto tab.
anyway its free.
Also read anything by Mark Sisson. He wrote "the primal blueprint" and runs the website "marksdailyapple.com" He is a low carb, hi fat kinda guy, along the same lines of keto diets and on there go to the archives tab and click on recipes. This a great place that shows 100's of low carb/hi fat and recipes and usually gives the nutritional values. So you could adjust the carbs yourself to make them even more keto friendly
also free.
Hope this helps man. And to be frank, yes this is the single best way to lose fat and retain muscle. Keep up the hard work and you will get there.
