There is definitely a trade off being on a ketogenic diet. For the most part you generally have to prepare all your own meals and eating out can be a little annoying at times especially when all the sides the restaurant has are carbs. The biggest issue people have with it is the first 2-4 weeks as you are adapting to the life without pasta, bread, rice etc. Strength will drop some during the first 2-4 weeks even with a calorie surplus because your body is changing over to ketones and fatty acids as its primary full source. You will also loose some water weight as you adapt that may make you think you are losing muscle, but you aren't its just water. I can't emphasis enough researching it more on your own and even checking out the books I mentioned in an earlier post. If you want to see if a keto diet is for you long term, I suggest using it on your next cut and then simply up your calories as you come off your cut. Any cut using the keto diet over 4 weeks and you'll more than likely be adapted. It is so much easier for me to get my calories in for the day now. Fat is 9 calories per gram where as carbs and protein are only 4. Its fairly easy to get 1000 calories in a sitting if you pick the right foods. So you don't feel like you are eating non-stop to the point you feel sick like a normal bulk. Anyway I could talk all night about this, but I'll stop here for now. Let me know if you have questions.
