It does get exhausting when people go on and on about malnutrition and starvation mode. It makes me want to not even talk to anyone about weight loss because they are so 1979 in their thinking.
It also explains why we're all so overweight, as a society, because people literally think that they can starve even though they've eaten all of their calories and nutrients, in surplus, for years.
So, people end up overeating and being frustrated when the scales don't move or move in the wrong direction, because they're told by people who have no clue that they'll starve even though they are large and actually do need to eat a lot less. They are just trying to do the right thing but getting incorrect information.
Dr Now (American bariatric surgeon) once told a woman that she wasn't going to suffer from malnutrition because she'd eaten all of her nutrients for the next 4 years. She was so mad at him for saying this but it made sense!!
I have previously put my calorie level here, when asked, and had posts deleted. It's ridiculous that misinformation that results in unhealthy outcomes i.e. obesity/overweight, is allowed, but not counter arguments that promote healthy BMIs because they are not 'popular' amongst those suffering from obesity or overweight.
I once lost more than 80 pounds eating 1800 calories a day but that's because my starting weight allowed me to lose weight, quickly, on a higher amount of calories.
As we lose and get closer to goal weight, the calories required to lose shrink further, and that's especially true if one is sedentary, older or petite.
