I remember when I was a teenager. I would eat Crisps and chocolate every lunch, and pizza and chips every evening. It was a Fast food house which is a bit neglectful, but understandable at my mum was a struggling single mum, that was how it was.

I was so thin all through my teens

Now I'm early forties. I eat pretty healthily. I go to the gym three times a week, yet I'm overweight and it takes so long for me to lose a pound.

How does age slow down metabolism so much? Agh

It really doesn’t. Look at the evidence. It’s your TDEE that’s dropped because you’re more sedentary.

BMI 23 so that is good enough for me

I think dieting is too hard so I have been focusing the last 5 years on building muscle and fitness. The fatloss then sort of falls into place

i have lost no weight as such, but much more muscle 5 yrs in even than I had in my youth

as a result I can eat quite a lot more

i think diets and restrictions are no way to live, but saying that I do about 15k steps a day and do gym 5X a week. It is a bit of a commitment and was only able to put so much time into myself and my health once kids were older teens

I don't think it does for everyone. I was lighter in my teens and early 20s but nothing really changed for me after my mid 20s. I'm 68 now and menopause made no difference, I weigh the same as I did 40 years ago. I don't diet but probably drink less alcohol than in my 20s.

It's taken me 4 weeks to lose a pound

I don’t know but I imagine, in part, it’s loss of muscle mass which we lose as we age if we don’t strength train.
