The scale can be misleading. It doesn't tell the whole story. Calorie intake does not play a part when doing something like this as your body has a limitless supply of them (body fat) stored and ready to tap in to. This is ketosis. When your body stops running on sugar and starts using all the fat that's been stored. This is a big shift for your body and it will do the work to use the fat as long as you support it by having all your Cambridge servings and ideally, nothing else but non-caloric beverages. The one exception is if you are adding a healthy fat source to your Cambridge.

It is quit common for people to have some weeks where they lose slowly, but drop inches or sizes. The human body is complicated and rarely behaves as we would like, especially when losing weight. Fluid fluctuations play a big part. Fat cells also contain fluid and as the fat is released, the cell can temporarily fill with fluid. Eventually it will flush out. Be sure to stay hydrated.

Your body is using the stored fat from your liver and muscles and other organs as fuel and converting some of it in to ketons for your brain to run on. It absolutely HAS to when it is being denied an outside energy source of a standard diet, typically high in carbs and sugar. Converting over to fat fuel is a process, but one your body is designed to do. My advice is to stay off the scale. It won't make you lose any faster and will likely only cause stress and doubt. Trust the process. Support your body and let it do it's work. Weight loss is never linear. It is more zig zaggy then straight. Just work your Cambridge plan and let your body do its thing!
