Right now I'm starting a tuna and water diet for the next 10 day about 100g of protein from the tuna. I will also take 40g of protein shake every other day to get some bcaas. my total calories will under 1000. I've been reading that this kind of diet becomes ketogenic(not sure about spelling) so burns fat instead of carbs. If I add about 30g per day of cod liver oil would that greatly increase fat loss but also aid me in lot lossing to much muscle?
