Hi @Atlantic
when I was young I was quite skinny and after going through puberty was quite surprised that I couldn’t continue to eat what I wanted with no consequences.
I put on 10 kilos in 30 years and when I was diagnosed with breast cancer age 62 determined I’d lose those kilos,
I saw a physical therapist to help me with an exercise programme but also changed my diet .
Eliminated sugary drinks, fast food ( McDonald’s, kfc, pizza.etc) drastically cut down on alcohol , sweets, chocolates , biscuits etc.
Ramped up consumption of fresh fruit and veggies, lean meat and fish.
I got a set of scales and kept a diary of what I eat.
Might seem boring but I lost the 10 kilos and
kept them off 2 years on.
It can be done , and in my case I feel so much better for it.
