Jennifer Lawrence is a woman whose thoughts on food I – like the rest of the internet – have a lot of time for.

Like Lawrence, food is one of my “favourite parts of the day” (seriously what a sad life you must lead if it’s not).

So when I heard Lawrence’s personal trainer Dalton Wong had teamed up with health journalist Kate Faithfull-Williams to publish a book called ‘The Feelgood Plan’, I was intrigued – if a little skeptical about how exercise plans and meal suggestions could improve your mood.

It goes without saying that Lawrence would only back a diet plan that includes pizza

The idea of a “diet and fitness” plan brings to mind deprivation, exertion and a strict regime – not elements that fill me with joy.

Yes, we’ve all heard the old chestnut about exercise releasing endorphins, but give me the choice between climbing onto a sweaty cross trainer and pounding the road to nowhere, or enjoying a meal out with friends, and it’s no competition which one is going to get my endorphins flowing.

But Lawrence has sung Wong’s praises: “Dalton is different to other trainers because he understands what my body needs – how to exercise, when to unwind, how to enjoy food.

“I could never live on a ‘diet’.

“Dalton taught me how to eat, move and live a delicious but healthy life.”

And she’s just one of Wong’s A-list clients – he’s also worked with Game Of Thrones actors Kit Harington and Gwendoline Christie, as well as Nicholas Hoult and Amanda Seyfried.

At just £11.99 for the paperback, ‘The Feelgood Plan’ is a lot more affordable than Wong’s £250 training sessions. So I gave it a try to see how it measured up to Lawrence’s list of the lessons her body needs: “how to exercise, when to unwind, how to enjoy food.”
