Suppression to me feels like almost no hunger at all. I am W3D4 and have only felt properly hungry once so far. Some days, I feel a bit peckish for about 5 minutes, then the feeling passes. But that's only very occasionally.
Most days, I could easily just not eat a thing if it weren't for the light-headedness.
I am quite lucky though in that I don't have to force myself to eat, like some people report. And maybe unlucky in that I don't particularly get fuller, faster. I think I've stretched my stomach over the years... I have noticed that if a meal is VERY big, I can't finish it. I went out for the most amazing Sunday roast this week and all I could eat was the meat, half the mash, and a small portion of veg. The roasties and yorkshire pudding remained unexplored. But the portion of beef was easily half a cow - I still stuffed my face... ;-) I'm not struggling to eat normal sized portions.
Food noise... I've got to a weird place where I want to want to eat. I miss the emotional side of enjoying food, food as fuel is a new concept and some days, I miss food for fun. But if I walk around the supermarket, all I actually want to eat is salad. I'll be interested to see what happens come winter/colder weather. I'm currently absolutely obsessed with M&S Feta & Watermelon Salad. 400 calories if I eat the whole lot, the crisp salad, salty cheese, cold watermelon, tangy dressing... It's all I want to eat. So I'm having that most lunches, with a 600-700 calorie evening meal that's protein-heavy. I don't weigh myself, but today's NSV is a skirt that I love that had become too tight to wear, now fits well on my waist. And I can see my arms are thinner. This is good enough for me.
