Welcome. VLCD is one way to go, but not necessary, to lose weight and can present problems if not managed correctly. Things to watch out for are getting enough protein to avoid slowing of your metabolism and getting enough micronutrients to avoid cravings. You may experience a period of low energy, the low carb flu, which will fade. I think another trap for some is frequency of eating. Eating too frequently maintains a high level of insulin which impedes the release of free fatty acid for fuel. Three square meals per day, just as we were recommended back in the '70s, allows your body to cycle between burning glucose and fat and avoids the difficulty of maintaining the state of ketosis (though nothing wrong with that if that's what you choose)
