Thinning hair, hair loss, flaky skin and nail problems are some of the first signs that your body may be lacking protein. Biotin, a water-soluble B vitamin, helps keep our skin, hair and nails healthy and looking their best.

Protein and biotin loss often go hand in hand, which is why many people experience hair loss when they don't get enough protein.

5. Fluid Retention
Swelling or Fluid Accumulation: Protein plays an important role in preventing fluid accumulation in tissues, especially in the feet and ankles.

Bloating can also cause abdominal swelling, the hallmark symptom of which is a swollen abdomen. However, this condition reflects a fairly severe protein deficiency (and is unlikely in developed countries).

6. Regular Illness
Frequent illnesses indicate a weak immune system, and immune cells are made of protein. One study in particular found that older women who consumed a low amount of protein for nine weeks had a significantly weaker immune response.

7. Brain fog
Brain fog, fatigue, and poor concentration can be linked to protein deficiency. Protein deficiency can also affect mood, anxiety, and sleep.
