A mum-of-two who used to gorge on "beige" food has revealed how she managed to lose more than two stone during lockdown.
Rhiannon Harrison, 29, tipped the scales at 17st 10lb before the stay-at-home restrictions were enforced across the UK.
At the time she admitted feeling sluggish and lethargic, using sweets and sugary snacks to keep her energy levels up to look after her two young boys Harry, six, and Iago, one.
But after completely altering her diet and taking part in regular exercise with her family, the Aberystwyth resident said her life has been transformed.
"It's had such a positive effect on my mental health, as well as my physical health," she said.
"I feel so much more energetic now, and I hope that even after lockdown is over we won't go back to our old ways."
Rhiannon, who works as a supply teacher, said most of the food she ate was processed, beige and convenient.
"I'd just eat crisps, sandwiches, just very stodgy stuff," she admitted.
"I'd spend my time making nutritious stuff for my children, but I wouldn't be looking after myself.
"I was just so unhappy. I was stuck in a vicious cycle where I'd feel uncomfortable with the way I looked and would comfort eat to make myself feel better."
In a bid to change her eating habits, Rhiannon decided to take part in an S4C TV show called FFIT Cymru, where she was given access to three diet and fitness experts.
They put her on a tailored meal plan and told her to limit her calorie intake to 1,600 daily.
"But there were things on their menu - like a breakfast omelette burrito - which I never thought I'd be able to have," she said.
"The difference in my diet before and after is that everything is now freshly made. This lockdown has given me the time to prepare my own meals at home.
"We even have fruit and vegetables in our garden now. We've just planted everything just to see what grows, from lettuce and potatoes to radishes, beetroot, spring onions and coriander."
As part of the FFIT Cymru plan, Rhiannon has also started exercising with her partner Gethin Evans and their two sons.
"My partner is furloughed, so we've had time to take part in exercise together and see the boys growing up," she said.
"FFIT Cymru has its own YouTube channel which has exercises for the whole family. It's also bilingual so it can be enjoyed in English and Welsh. We also have a treadmill in the house which has proved very useful, and we go for back rides.
"I alternate my exercise. One day I do cardio and the next resistance - and I've really felt the benefits. My partner has lost two stone too, and my eldest son - who is energetic and is sports-mad anyway - has loved how active we've become as a family."
Rhiannon said that she hopes to take her new lifestyle habits into the classroom once she returns to teaching.
"I'm really looking forward to taking PE lessons and advising them about healthy eating," she said.
Since the start of lockdown, Rhiannon's weight has reduced from 17st 10lb to 15st 8lbs.
"Four years ago I was at my fittest. I was a big fan of the gym and I was weighing 12st 12lb. I loved that weight, but when I had my second child I couldn't stay in shape," she said.
"I hope by September to reach 13st and then get to target by November/December time."
