OP I'm sorry to say most slim people I know just put up with hunger.
Absolute and utter twaddle. This thread is appalling, the majority of the replies sound deeply disordered. No one ought to be starving eating a balanced diet that doesn't run in to excess. No one. Unless they have a health issue.
Whilst fat isn't bad (no food is 'bad'), it is often incredibly calorie dense. The obsession with avoiding carbs is an exclusion diet, not a balanced diet, and pulling away bits of simple bread or crumb from food absolutely smacks of ED behaviour, which is sadly so integrated into women's lives now it doesn't even stand out as shocking anymore.
Carbs in their healthy form affect the brain, mood, energy. We actually do require good carbs even if not in large amounts. Many, such as wholewheat pasta contain oleic acid, others are high in protein and are very satiating.
I know countless people who fell off the low carb bandwagon, and most professionals (ie, not youtubers) would never advise cutting out an entire food group. It isn't sustainable, just like low fat isn't, but moderation just doesn't sell, nor does it assist women in self loathing, so the cycle continues.
One friend of mine cut carbs to almost nothing for over 10 years, during which her weight went up and down regardless. She was piling on the saturated fat and fell for the trend driven garbage that we only need protein and fat to survive. She eventually began to eat small amounts of healthy carbs and felt much better for it, and has since managed to keep her weight in a good place with moderation.
Self denial is lose lose. It doesnt work. And no, naturally slim people do NOT starve or feel hungry. If you are slim and starving I would advise seeing your GP.
I have always been at the thin end and have struggled to gain over the years, so the presumption that all slim women are starving is severely screwed up. I honestly would not advise anyone to seek assistance in this section of MN, it's the first time ive popped in and wft, this place is heaving with issues.
Many users are sincerely kind and helpful, but sadly they are outnumbered by extreme diet advice.
OP, misery loves company, I don't think it's healthy in here. Good luck.
