I have seen a few videos from the diet doctor, who looks at lots of different diet techniques
he reviews lots of difference diets and other things like learning, is salt good for you etc.
he has had lots of people write in saying how effective the low carb diet was for them
more success stories here
he has an interesting article on how to lose weight (step 1 - low carb diet)
A 2012 study also showed that people on a low carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually doing it.
Bottom line: A low carb diet reduces your hunger and makes it easier to eat less. And it might even increase your fat burning at rest. Study after study show that low carb is the smart way to lose weight and that it improves important health markers.
