I am wondering if my overall calories are too low? I keep my calories at about 1800 a day. I am on a ketogenic diet consisting of protein shakes, natural peanut butter, avocados, hard-boiled eggs, and fish oil. Due to financial reasons for the past 6 weeks my food intake has been limited, and my ability to lift have been put on hold.
I have been employing calisthenics, like push ups, calf raises, and body weight squats. For conditioning I do tabata thrusters about twice a week and an hour of cardio a day consisting of walking with a weighted pack. I have lost a significant amount of weight, unfortunately some muscle.
I am now able to lift, so I was wondering if I should increase calories as a result? For example, utilizing high GI carbs after lifting. Any input is appreciated.
