John Whaite has discussed his recent attention deficit hyperactivity disorder (ADHD) diagnosis, describing it as "the most liberating thing".

The Bake Off winner recently shared that he had been diagnosed with the condition with his 300,000 Instagram followers.

But he has now revealed his response to the news, explaining how it helped him make sense of his past behaviour.

“It turns out that I’ve got ADHD," he told Steph McGovern on Monday's episode of Channel 4's Steph’s Packed Lunch. "There’s a lot of scepticism at the moment in social media about ADHD but it is a recognised factual diagnosis, I was diagnosed by a psychiatrist.

“For me, it puts a lot of perspective and a lot of insight into my life. People often fear diagnoses, but actually this for me is the most liberating thing I think I've ever had."

The chef then said discovering he had ADHD was like ”multiple jigsaw puzzles finally getting put into place".

“Now I can look back at my life, the things I've done, at the conversations I've had, the arguments I've had, with a new perspective, it's beautiful," he added.

In terms of treatment going forward, Whaite says he is exploring CBT (Cognitive Behavioural Therapy), medication, as well as reading a lot about the subject.

Whaite isn't the only celebrity to discuss ADHD.

Sam Thompson explored whether he has ADHD in an E4 documentary that aired earlier this month, after his girlfriend Zara McDermott said he'd been displaying signs for years.

As he approached his 30th birthday, the former Made in Chelsea star made the decision to finally get tested for ADHD and explore what a possible diagnosis might mean for him.

He said he is known by those close to him for his impulsiveness, for forgetting appointments and losing things like car keys.

Olivia Attwood previously discussed being diagnosed with ADHD as an adult, revealing how it impacts her everyday life. The former Love Island contestant, 32, spoke about the condition while appearing on ITV's Loose Women, explaining that she was diagnosed while seeking treatment for anxiety and depression.

What is ADHD?

Many think of ADHD as a childhood condition, but a growing number of people in the UK are being diagnosed with the condition in adulthood.

According to the NHS, ADHD is a condition that affects people's behaviour. People with ADHD can seem restless, may have trouble concentrating and may act on impulse.

The exact cause of ADHD is unknown, but it has been shown to run in families.

What are the symptoms of adult ADHD?

While symptoms are similar for both adults and children, elements can differ or change as we get older.

"Adult symptoms of ADHD also tend to be far more subtle than childhood symptoms," the NHS explains.

Some specialists have suggested the following as a list of symptoms associated with ADHD in adults:

• carelessness and lack of attention to detail

• continually starting new tasks before finishing old ones

• poor organisational skills

• inability to focus or prioritise

• continually losing or misplacing things

• forgetfulness

• restlessness and edginess

• difficulty keeping quiet, and speaking out of turn

• blurting out responses and often interrupting others

• mood swings, irritability and a quick temper

• inability to deal with stress

• extreme impatience

• taking risks in activities, often with little or no regard for personal safety or the safety of others – for example, driving dangerously

ADHD symptoms in women may be more subtle, including anxiety and low self-esteem, according to the Priory.
