You should probably up your protein powder to 2 scoops per serving. You are pretty low carb. You might consider a keto diet with a bit higher healthy fats if you're going to go that low carb anyway. Make sure your lean protein measurements are in cooked weight. 8 oz raw may be a bit on the low end for your protein needs. I would also consider dropping the veggies down to 1 cup and maybe adding some EVOO or mac nut oil to them if you decide to go the keto route. Best of luck whatever you decide. I don't know how much protein is in the tuna that you have, but I would simply suggest that you shoot for 40 - 60 grams of protein per meal. Make sure that your whey protein is as pure as possible. You do not want the additional calories of carbs and fat from your whey protein during a cut if you can help it.
