You may not be losing because low cal isn't always the best way to lose weight. You should be getting in no less than 300-500 calories less than your BMR (factor in any exercise to that number and up the calories as needed). If you are eating too little or not enough protein (.8-1g per desired bodyweight) or fiber (fruits/veg) as well. Also, you may be carb sensitive. In spite of complex carbs, consider eliminating them and keeping carbs to <20-25% of your diet. If this is a VLCD I'd suggest you reconsider. You don't have to pay a lot of money to lose weight. You just need a good plan, equipment, time and commitment. If you need help, I can make some recommendations.
FYI a Tanita is a brand of scale that measures many elements. Mine measures weight, bodyfat %, water%, muscle lbs, visceral fat, metabolic age and level of fitness. It is known to be highly accurate and has home and professional models. I have found mine within 2lbs or less of a doctor's scale....
