What is the fastest way to lose weight instead of surgery?

Negative balance: Weight loss is achieved by increasing energy/caloric expenditure and decreasing caloric intake, a negative caloric balance. The combination of diet, exercise and/or restrictive surgery procedures all achieve negative caloric balance. If you can't achieve the negative balance, then surgeries are great.
