She also responded to claims made yesterday on Lorraine by a personal trainer who has worked with the singer.
Trainer Camila Goodis claimed diet accounts for 95 per cent of weight loss, and exercise five percent.
Dr Zoe said: “When it comes to doing the exercise – Adele’s been going a lot of exercise.
“Just a little bit of exercise wont help you lose weight, but it will make you feel better.”
She added: “If we try and do something radical it’s not sustainable, something like eating 1,00 calories a day.
“It’s about making small changes. Instead of going to the pub, go for a coffee and a walk instead.”
