A former Secret Service agent who protected Presidents Barack Obama and George H.W. Bush has lifted the lid on the key signs that reveal someone is lying to you. 

Evy Poumpouras, who received a U.S. Secret Service Medal of Valor for her heroism on 9/11, served in the Secret Service for 12 years and stood out on presidential detail for various leaders. 

After leaving the service, the former agent - who 'grew up in the White House' and started her career under President Bill Clinton - has been sharing her insider secrets with the world. 

As an interrogator and agent, Eva became a pro at reading people and has now dished out her tips to spot a liar and how to get anyone to do whatever you want in an episode of The Diary Of A CEO podcast hosted by Steve Bartlett.

Evy - who spent eight years conducting polygraph tests - revealed the biggest mistakes people made and the one phrase that automatically meant you were guilty as she shared how to use the skills she was taught in the Secret Service in your everyday life.

Being born and raised in New York City, Evy knew she wanted to protect her land and so from a young age she joined the NYPD.

By age 22, the blonde powerhouse entered the Secret Service. 

Beginning her presidential detail under Clinton, she learned many tricks that she later applied throughout her career and personal life. 

Speaking on the podcast, she said: 'I grew up in the White House. I grew up in the US Secret Service. That's how I grew up, those things helped shape and mold me.

'It's easier to get into Harvard than it is to get into the Secret Service.' 

Evy detailed the various skills she learned - including how to spot a liar based on some giveaways. 

She explained that the biggest mistake people often made when fibbing was talking too much. 

Evy noted that to spot a liar, you needed to first find their baseline.

A baseline is someone's usual pattern of behavior. 

So, if they tend to make eye contact and avoid it when a certain topic is brought up it tends to mean they are lying. 

She noted that you need to tune in on what caused them to change their baseline and that is how you will discover they are lying.

The former Secret Service agent also shared the one phrase that was often a 'red flag.'   

'One of the things I have heard a lot of guilty people say is, "I swear to God,"' she said.

Evy noted that when people brought 'religion into it,' she immediately thought they committed the crime. 

The ex-agent also shared how you can get someone to do whatever you wanted, which she revealed went back to talking too much. 

She added: 'The biggest mistake people make is they talk too much.

'You need to understand that person's motivational mindset, what they are motivated by. That is your value and belief system. If you give people enough space, they will reveal themselves to you.

'We are so busy talking and making noise and thinking me, me, me, me and you know what, nobody cares.

'People will show you what they care back if we just hold back and stay silent. You have to be non-judgmental or people will shut down.' 

In addition to getting people to do what you want, the ex-agent revealed that you can also demand respect from others. 

She explained that it started by how you reacted to disrespect. 

Evy said that when someone disrespected you, you have to take that and ask yourself why they thought they could behave that way around you. 

She said: 'People are so afraid of stepping on someone's toes or hurting someone's feelings, and that's worse.' 

The former Secret Service member noted that to become a good leader, you couldn't let your emotions take over. 

She added that great leaders were 'not driven by emotions.'

'I have never heard a US President yell or lose himself,' she said.

Evy also spoke about her work with George H.W. Bush and the one rule he had in place. 

She revealed that the former President would send Secret Service agents 'home' if he heard their 'phones go off.' 

In the past, Evy revealed she was 'outraged' that she could 'do nothing' to protect Michelle Obama from racist comments because of the freedom of speech.

The former agent wrote in her book, Becoming Bulletproof, that Michelle, the first black First Lady, had to withstand disparagement 'that none of her predecessors ever faced.'

'I was on her protective detail when we were driving to a school to deliver a speech; we passed someone on a bridge holding up a shockingly racist sign directed at her,' she wrote in her book.

'I remember feeling outraged - after all, it was part of our job to protect the first family mentally as well as physically. But if the First Lady saw the sign, she gave no indication of it.'

She has also previously spoken out about her heroism on 9/11 following the attack of the World Trade Towers.

Evy nearly died trying to drag people to safety as the towers came down. 

For her work, she became one of only five women to receive the Medal of Valor.
