The colossal machine that is the diet industry has one huge benefit - there are now so many companies and different options out there that dieters are spoilt for choice.
If you are serious about losing the kilos, forget about quick-fix options, or those with unworkable restrictions.
Weight loss and keeping it off long term required lifestyle changes, said Jo-Anne Dembo, principal dietitian at Diet By D'Zyne.
So whichever method you chose to adopt, the most important aspect was that it was sustainable.
The Foodie dietitian Laura Kiely said this meant first considering the reasons behind your weight gain.
Often weight gain or yoyo dieting were not as simple as eating too much chocolate because it tasted good.
In her clinical experience, Ms Kiely said she found common weight gain reasons people cited included emotional, medical, occupational and even poor education about food choices.
"It is important to address the many, complex factors leading to weight gain or unsustained weight loss. Most 'quick fix' programs do not address any of these issues," she said.
Mind&Body takes you through the maze of diet options - from home-delivery meals, group meetings, private one-on-one consultations and even to the new frontier of dieting online:
Home delivery: Home-delivery meals were a convenient way of having a calorie-controlled meal, and were suited to those who were time-poor and in need of low-calorie meals, Ms Dembo said.
"They are also the ideal alternative for those who rely on takeaway foods. And they are useful for people who live alone and cook for one as, for some people, cooking for one on a daily or regular basis may seem more like a burden than a pleasure."
Group meetings: Weekly group meetings tackle various topics of healthy living and problem areas for dieters, as well as members weighing in and sharing achievements.
Research had shown that people who publicly shared their goals with others were more likely to succeed, Ms Kiely said.
Private consultations: People would lose weight if they chose an approach or diet that worked for them, Ms Kiely said. But the real challenge came with maintaining the weight loss.
"This is where a dietitian - preferably one who is also skilled in counselling modalities such as acceptance and commitment therapy and cognitive behaviour therapy - can be of assistance," she said.
Online: Online programs were fantastic for people living in rural or remote areas as well as for those who were time-poor and couldn't make meetings or consultations during regular business hours, Ms Dembo said.
Ms Kiely said that this option might also appeal to people who responded well to numbers and visuals of their progress.
Many online programs were free, easily accessible, private and portable.
