Obesity and sugar intake are major problems worldwide. They have large medical, economic and social impacts and influences. Concerning these topics, meaningful studies were recently reported from the United States (US)  and the United Kingdom (UK) . The author and colleagues have continued clinical research of low carbohydrate diet (LCD) for long years. In this editorial, key points of these topics are described.

According to previous epidemiological investigations, SSBs intake has caused a higher risk of diabetes, coronary heart disease, and stroke [3,4]. National Health and Nutrition Examination Survey (NHNES) data showed a relationship between baseline intakes of added sugar and SSBs with elevated CVD mortality .
