It will take Rick 188 weeks to achieve his goal of losing 188 pounds following 3500 kilocalories rule.
According to this question, Rick wants to safely lose weight using 1 pound of weight loss per week, known as the "3500-kcalorie rule".
This rule simply means one should reduce daily kilocalorie intake by 500 kcalories; over a seven-day week you would lose 3500 kcalories
which is approximately 1 pound.
This means if 1 pound is lost per week, 188 pounds will be lost in 1 × 188 = 188 weeks.
