The higher fat part of LCHF should help keep you feeling nice and full, so make sure you're consuming adequate good fats and oils, and hopefully you'll find you won't need to snack.
You don't
have to eat Greek yoghurt, but
definitely keep well away from any low fat, lite, added sugar, or added fruit ones. And if you want yoghurt with fruit, just add your own berries instead.
Coffee or cocoa with cream, bouillon or stock cubes with added cream or sour cream, small portions of berries with cream (or the dreaded yoghurt
), a piece of high cocoa (75% or more) dark chocolate, cheese, olives, nuts and seeds, a spoonful of almond or coconut butter, fat balls (look on Google for recipes for these), are all good small but filling options if you find have to snack. Low carb microwave muffins made with ground almonds or hazelnuts, flax seed, coconut or sesame flour (or various combinations of these) with or without various flavourings or additions - grated cheese, spices, herbs, chopped nuts or olives - are slightly more substantial depending on size. And small avocados, boiled eggs, slices of ham, corned beef and other cooked meats, or chicken drumsticks, could also be somewhat more filling snacks - or with added salad, etc, eaten as small meals.
