I'm very slowly losing weight at the moment. If I fancy a snack I'll try to go for a miso soup (from a sachet), or about half a dozen almonds. If I'm really desperate for chocolate I'll either have a "fun-size" portion (tiny bars rather than proper "fun" size), or I'll have a pickled onion or a gherkin (nothing kills the craving for chocolate like a pickle). I always eat a healthy breakfast, if I can make it through the morning without uncontrolled snacking then I know I'm halfway there.And if it all goes to pieces I try to stay positive and make a fresh start. Good luck!
