Sir. what would be ideal weight for male height 5feet 6.5 inch?

You choose: The "ideal weight" charts are subscience / entertainment; olympic sprinters are "underweight" & super-fit linebackers "obese". A person's best weight is whatever looks and feels right to that person while he / she is able to keep up with peers at the fitness activities that he / she enjoys. I hope you've chosen a smart, fitness-focused lifestyle.

BMI: Use a BMI calculator to know. SEE: https://www.nhlbi.nih.gov/health/educational/lose_wt/BMI/bmicalc.htm. BMI Categories: Underweight = <18.5 * Normal weight = 18.5–24.9 * Overweight = 25–29.9 * Obesity = BMI of 30 or greater. By checking your BMI you can get an idea of whether you are in a healthy range.
