After analysis, researchers found that adults following the rapid weight loss program were more likely to achieve weight loss goals compared to those on the gradual program. In fact, 81% of participants in the rapid weight loss group achieved weight loss goals, compared to just 50% of the gradual weight loss group. And contrary to current beliefs, there was no significant difference in weight regain in either group after three years. Three years after the initial diet, nearly three-fourths of all participants regained the weight they lost, regardless of their diet.
The prevalence of obesity is increasing and according to the latest statistics of the world health organization, 13% of adults worldwide are obese and 39% are overweight (1). Obesity increases the risk of metabolic diseases, cancer, and cataract (2, 3). Statistics have shown that obesity and its consequences have high costs for communities (4). There is a positive association between body mass index (BMI) and direct and indirect (due to premature deaths) health care costs. Indirect costs of obesity (54% to 59%) have been reported more than the direct costs (5). In the last century, due to the increasing prevalence of obesity and its hidden costs, control and treatment of obesity requires more attention.
Green tea can help you lose weight. Several studies have suggested that the flavonoids and caffeine in green tea can help elevate metabolic rate, increase fat oxidation and even improve insulin activity. One study showed that those who consumed green tea and caffeine lost an average of 2.9 pounds during a 12-week period, while sticking to their regular diet. Another study suggested the increase in calorie output was equal to about 100 calories over a 24-hour period.
