Firstly, from a physical perspective, there's increasing evidence that being overweight but with an active/high fitness lifestyle is far healthier in the longterm than inactive 'normal' weight.
Secondly, we also know that weight loss and fitness are more than just the physical. A £multi billion diet industry tells us that. In mental health nurse education, we are actively seeking, learning and benefitting from a programme called 'Experts by Experience.'
Lastly, for those posters who answered simply no, that's fine, thank you. For those that piled on with more judgemental attitudes, I guess manners, #bekind and science seems to have passed you by.
Yes, the majority of obesity is caused by an excess of food in over energy used out. The majority. Some people will have health conditions and/or medication that causes/exacerbates weight problems. Medications to control some really serious illness. Life limiting illness. Maybe even those 'overweight' dieticians and nurses.
