I'm afraid we may need more info - what you eat, why you think it isn't working?
As nosher says, i don't eat regularly, like he does. I eat twice a day nowadays, either breakfast and evening at the weekend, or a small lunch and larger evening meal Mon-Fri. Sometimes i only eat once. I do best if I eat no carbs til evening. So i will have a coffee with cream that will keep me going for hours rather than eat carbs or protein, because they both affect my blood glucose in the mornings.
It is all low carb, and I certainly don't bother with small meals and snacks. I eat when I'm hungry, and eat well, in satisfying amounts and then forget about food til I get hungry again.
I must say it is delightful after all those years of phaffing with snacks and regular eating.
The secret (for me) is eating enough fat and getting the carbs really low. Fat is slow release, doesn't bump up blood glucose, is satisfying and stops you needing to keep topping up endlessly with snacks. I love it.
