You are far too fat to begin a mass gaining diet. Now, I am not all for being some pretty boy all year long, but 27% bodyfat is pretty damn chubby! I, myself, have gotten up to 20% bodyfat before and I was not looking pretty. However, my strength was the best it ever was. I, like PX, also believe that the bodyweight I was at that fat percentage, 240#, allows me to carry more muscle mass at my current weight, about 225# at 5’10".
If you are just starting out or coming back from a long layoff, you will be able to add muscle and lose fat at the same time; maybe even do BOTH SIGNIFICANTLY.
You do not need any carb cycling at your bodyfat. If you are carrying that much fat, you can lose weight on a lifestyle diet, eating what you are supposed to 90% of the time. Just use a caloric reduction through less food and increased exercise. Leave the “tricks” for later. I do not find tricks to be useful until you are at an advanced or considerably lean body composition. They are meant to be used when you reach plateaus with more conventional methods, in this case, increased activity and less food and proper food choices.
