Weight loss is fascinatingly easy, the problem with weight in the western world is that the fitness industry is incentives to entrap the population.
As a PT, my first advise to every new client on a weight loss program was not to extract ANYTHING from their lifestyle first up. The fact that they are here is a huge sign they are ready for change, but change must be sustainable and life long.
The first step was always to eat as usual, but exercise and add water. It really was that simple. Drink a cup of water on first wake up, one for lunch and 1 before bed, and as much as they like in between, then turn up to PT sessions.
I designed all of my self efficacy building paradigms on feelings, and ability, rather than weight or inches. By the end of month 1, every single person who engaged fully reported massively increased sleep, and energy throughout the day.
After that, reducing dietary intake was easy, replacing convenient processed foods with alternatives, and strategising drinking before eating (most people confuse thirst for hunger) started to reduce fat stores, and increase mobility, allowing them to perform better and better.
The downside was always program uptake, as soon as people hear that this isn't a 4 week easy fix they drop out hard, they want weight watchers results, and dont care that it is a scam designed to dehydrate you, drop weight (water) and then balloon back up using yourself as a weapon to blame yourself.
I met a friend recently who was using Mounjaro, she was an energetic bubbly big girl, full of life. Hadn't seen her in nearly a year, and she looks 10 years older, meek, lacked any sort of life. Really reserved, it was the saddest thing id ever seen. TBH that's my only experience of thewlse weight loss drugs, so maybe not a fair reflection of 1 case.
Also, I havnt PT'd for nearly 20 years lol
