^ I really agree with this. To loose weight and be healthy (because some slim people are horribly unhealthy and it does catch up with you), people need to eat mostly healthy, natural & not overly processed odd
There is lots of academic research (eg Barbara Rolls Volumetrics, The End of Overating etc) that people are used to eating a certain volume/weight of food every day and ‘expect’ that /feel unsatisfied if they don’t
So eating a large quantity of food but reducing the calorie level (by bulking up with veg , more fibre on beans/whole grains, & water containing food like soups, stews, fruit etc) gives you that satisfaction/volume with more nutrition & fewer calories
A huge number of diets fundamentally switch you to eating more veg/unprocessed foods as a means of reducing the calorie level in a sustainable way
Understanding how different foods affect your blood sugar levels & so hunger/cravings is also important for managing your weight. In my case the more bread/baked good I eat the more I want so I aim to have those a couple of times a week vs daily, & know I’m overdoing it when I crave those so have a few days without
I’m not willing to give up my favourite foods (bread/baked goods in my case) entirely but being aware of how they affect me/can start a spiral of overeating has helped me set some limits
I think you can lose weight and eat ‘anything you like’ as long as that is only say once or twice a week for calorie dense and less nutritious foods (fried foods, cakes etc) & if you are overweight it’s more likely than not you have a strong appetite/hunger and don’t eat tiny servings so would not be happy to do so long term/might be setting yourself up for a binge/starve cycle if you try
