To lose weight we need to take in fewer calories than our body needs. When this happens, we draw on our fat stores to provide us with the extra energy we require to function properly. In the long term, this means we lose fat, and in turn lose weight. These programs work by replacing meals per day with specialised formula food, which are a complete meal. Meal replacement programs combine a meal replacement regimen with additional health supports such as physiotherapists.
The program is a combination of LCD (Low Calorie Diet) and the natural process of ketosis. Ketosis happens after 48 hours when body detects that it doesn’t have getting enough carbohydrates to operate as it usually does. The body therefore ‘switches over’ to a different method of providing fuel for itself – your fat stores.
Many people like meal replacement products because they are convenient, they take away the need to think about food during the day. The meals are strictly portion controlled. Meals are usually designed to be filling, reducing hunger between meals. Furthermore meal replacement diets are advantageous as the amount of calories in each portion has already been calculated. This makes it easier to keep energy intake down leading to greater success with weight loss.
Many people who enjoy cooking or preparing food may find the program too disciplined. In addition there is a limited amount of variety available when consuming whole foods. The flavours can also be limited and many people who are lactose intolerant may find that some sachets/shakes are milk/skimmed milk based.
