You know the BMI scale is bullshit right? It was developed in the 1800s with an abysmal sample size that is not considered scientifically valid. It doesn’t not take into consideration muscle mass and bone density which is a far better indicator of good health. These days you could take an “everyday athlete” who goes to the gym regularly and has a decent amount of muscle and a “skinny fat” person who holds large amounts of fat around their organs and the “skinny” person would be seen as being the “healthier” person.She is most definitely overweight, and she holds weight around her abdomen - this is known as visceral fat and it's the most unhealthy kind of fat to "wear" because it surrounds your abdominal organs.
Overweight people like Helen being seen as a normal size in the UK and USA doesn't make it healthy I'm afraid, it's just a reflection of the unhealthy diets and lifestyles that people have here. A quick Google search shows this:
"Data from the Health Survey for England (HSE) conducted in 2018 indicated that 31% of adults in the United Kingdom were recognised as clinically obese with a Body Mass Index (BMI) greater than 30. 63% of adults were classified as overweight or obese (a body mass index of 25 or above)"
So a "normal" size in the UK is overweight. No need to feel sorry for me, I'm very happy with my body and really enjoy being active and eating good food to look after it as best as I can.
