Johnny is 10 years old. he has had minimal protein intake for the last two years. he has just recently had surgery. what are the likely results of his deficient protein intake?

A sign to look for that might indicate a lack of protein in the diet is a feeling of low energy, moodiness, and the inability to handle stress well. Without protein to stabilize the blood sugar, the tendency to experience exhausting highs and lows in mood and energy increases.
