Strictly contestant Vanessa Feltz is predicting she could end up piling on weight rather than shedding pounds like many past celebrities.
The broadcaster has been turning to food keep up her energy levels as she struggles to balance her work schedule - which involves rising at 3am for her radio show - with training.
Vanessa, who has battled with her weight in the past, said: "I wonder if I will be the only person on Strictly who will put on weight? Everyone said I'll lose weight - so far, if anything, I'm sure I have put weight on. I will be the only person to dance on Strictly to put on weight. I'm cream crackered - where will I find comfort? In the arms of the blancmange."
Meanwhile, celebrities on this year's Strictly Come Dancing have outdone last year's batch by putting in way more training during their first week
Hollyoaks star Ashley Taylor Dawson is among those who have been putting every spare moment into their routines, as he dances until midnight each day after finishing filming on his Channel 4 soap.
The actor, partnered with professional dancer Ola Jordan, has been finishing filming and then starting his training at 8pm, finishing at 2am on one occasion.
A show source said: "The celebs are really going for it, the majority have been training five days a week already, compared to last year's four days. And some of them are putting in extra hours over the weekend to push things further. They are fitting hours in all over the place, especially the likes of Mark, Patrick, Vanessa and Rachel who are fitting it around other work commitments. And Ashley has trained until gone midnight with Ola this week, even though he is filming Hollyoaks each day."
Ashley is also on high alert for the arrival of his second child which is due in the next fortnight, close to the first live show of the latest series of BBC1's Strictly.
"Every time my phone rings we panic, I'm on standby at all times," he said.
BBC Breakfast host Susanna Reid has been battling fatigue with what she calls "micro-sleeps" during training as she fits rehearsals into her busy days which involve commuting between her London home and the studios in Salford where her morning show is filmed. "I'm not really falling asleep, my eyelids just close for longer than they should," she said.
