1. This person raises his or her eyebrows
  You suspect something’s up, and you’ve called your date out on it. The person   then offers an explanation, ending things with a “you do believe me, don’t you?”   look, eyebrows raised. This key body language piece indicates that your date   is not being fully honest. He asks,“You know that phrase, ‘lying eyes?’ A lot   of times, it’s more in the lying eyebrows, especially with women, so pay attention   to them when a woman is speaking to you.”

2. The pace of your date’s answers varies
  Though your date may be offering flawless answers to your questions, what may   actually give him or her away is the rate at which those answers get delivered.   Pay attention to inordinate time differences in your date’s answering style.   If he or she rushes to answer instead of the usual, halting speech or pauses   when rushing through words is the normal pattern, that’s a hint that something   is up.

3. Your date compliments you at an inappropriate time
  A man often compliments a woman when he’s trying to pull a fast one on   her. If, in the middle of his explanation of his whereabouts, he comments on   your dress or asks if you just got a haircut, be suspicious. Guys who do so   are trying to distract you and divert your attention away from their half-truths   or other deceptions. Don’t fall for it.

4. Your date plays with her hair
  When a woman is being deceptive, her behavior will actually be quite similar   to when she’s trying to seduce you. When you think about it, the two actions   are somewhat linked, even though they have different motivations behind them.   Therefore, if you’re trying to assess your female date’s honesty,   look for a sure sign of flirting: playing with her hair, a historic symbol of   romantic interest and attraction.

5. Your date wrings his hands
  If a guy is wringing his hands when he’s speaking to you. Why is this an indicator   of dishonesty? Hand-wringing not only signals stress, which is an indicator   of deception, but putting his hands in between his body and yours creates a   barrier. A guy creating this kind of barrier is usually hiding something.
