No, its not going to work.
The body demands insulin in order to shuttle certain amino acids into the muscle. Without enough carbs, you forfeit the ability to supply the essential nutrients to the muscle to grow.
In fact, I'd place money on the fact that you have likely lost a sizeable amount of muscle while on Keto. Not to mention to consequences it has on ur heart.
I'd love to go into the metabolic difference between fats and carbs, but its impossible to convice Ketoers any different. Yes, cutting carbs means losing fat but it also means losing muscle. So Keto and bulk? Absolutely not. Keto and maintenance? MAYBE. Keto and getting smaller? Absolutely.
Stop eating so much fat, start eating slow releasing carbs like sweet potatoes, leafy greens, rice, and legumes and start eating lots of protein as well, placing emphasis on whole protein sources for 60% of ur protein needs.
Do cardio, since aerobic activity targets fat for energy. Pre-breakfast is the best time for this. Do anaerobic activity for muscle growth. Eat tons of healthy carbs and you'll grow.
