Falling off from the ride to physical fitness is never an easy recovery. To return to his healthy course, a person must abandon his traditional lifestyle and boring routines.
Take this Leicesterian mother known as Karen Sharpe, as an example. This 37-year old's resolution was quite easy but promising-- she simply got rid of her usual nightly fast food, adopted a balanced diet, and invested more time in exercising.
A morbidly obese mother who spent almost $6,000 a year on fast food has dropped 10 dress sizes after shedding almost half her body weight.
Karen Sharpe, 37, has slimmed from a size 32 to a healthy 12/14 after ditching her diet of Chinese food and starting to exercise regularly.
The mother-of-four weighed 400 lbs and regularly ate Pot Noodles for breakfast when she was at her heaviest.
At her lowest ebb, she admitted to buying Chinese takeout five times a week, spending $22 each time.
But now, Mrs Sharpe, from Leicester, has given her lifestyle an overhaul, dropping down from 400 lbs to 198 lbs.
'I've always been big,' she said. 'I had a tough childhood and food was where I found solace. Some people turn to drink, some people turn to drugs I turned to food.
'It look me a long time to realize that eating a pack of donuts wasn't going to solve all my problems.'
Growing up, Mrs Sharpe's size saw her regularly teased.
'School was difficult,' she recalled. 'I kept my circle of friends quite small to try and avoid being teased as much as possible, so I don't think I got as badly bullied as some people do, but it was still tough.'
Despite trying various diet plans over the years, nothing seemed to work for Mrs Sharpe.
On a typical day, she admitted she would eat a Pot Noodle for breakfast,.
This was followed by chicken nuggets and chips for lunch and a takeaway for dinner - as well as snacking 'almost constantly' on crisps and chocolate throughout the day.
By February 2009 she found her size was not only damaging her self-esteem, but also causing her physical pain.
Mrs Sharpe found it difficult to walk, with her weight causing agonising pain in her legs.
'It got to the point where I didn't want to leave the house because it was too painful to walk,' she said.
Desperate to change, she sought advice from her doctor, who told her that she would be unable to lose weight naturally, suggesting instead she join the waiting list for a gastric band.
She started to visit a dietitian, who helped her reshape her eating habits.
Then, the following week, she decided to join Weight Watchers in a bid to shift some extra pounds before the operation.
'I was told the wait list for gastric surgery could take up to two years,' said Mrs Sharpe.
'I didn't want to be the way I was for another two years. My children were growing up, and I just felt like I'd miss so much waiting.
'I joined Weight Watchers to try and lose a couple of stone to help with the pain of walking around before I had the surgery.'
The pounds began to fall away, until eventually, spurred on by her success, Mrs Sharpe decided to get to her goal weight via healthy eating and exercise instead of through surgical help.
She explained: 'I know people who've had surgery and, while they did lose weight, they never addressed the reasons why they were big in the first place.
'I also met a lot of people whilst on the waiting list who cheated the band, doing things like melting down Mars Bars so they could still indulge.'
By the beginning of 2015, Mrs Sharpe had lost more than ten stone.
Then, after switching to a new plan called SmartPoints, she lost a further two stone in just eight weeks.
Now, she is just 8lbs away from her goal weight of 190lbs, and wears a size 12 to 14.
Instead of snacking on quick-fix junk, she enjoys freshly prepared healthy meals.
Although she said she will allow herself a 'few treats' over the festive period, Mrs Sharpe is not going to be too overindulgent this Christmas.
'Before, I'd have piled my plate high with food just because it was there. I also used to have loads of Baileys, which is the worst thing you can drink.
'I'll still have a few treats, but nothing major. I'll have butternut squash instead of potatoes and that sort of thing but I'll still enjoy some pigs in blankets.
'But the fact is I don't even like the kind of food I used to gorge on anymore.'
Mrs Sharpe also works out three times a week, and has even become a Weight Watchers leader.
'My life in unrecognizable now,' she said. 'I can play football and run around after my children instead of sitting on a bench watching them.
'For the first time in my life, I can shop in regular high street shops. I wear things I'd never have dreamed of before.
'I used to hate myself. I didn't like mixing with people or going out. I still struggle with my confidence but I'll get there, in time.'
