Just got home from my morning workout, I rode the Trikke today. Lots of fun great exercise.
Tip 1: Find out how many calories you need
BMR (Basal Metabolic Rate)
Body Weight [lb] x 15 + (moderate activity [mins/day] x 3.5)
Since you wish to lose weight, your target = BMR - 500 kcal
For instance, you weigh 140 lb and you perform 20 mins of moderate activity every day. BMR of this example = (140 x 15) + (20 x 3.5) = 2100 + 70 = 2170 kcal. BMR minus 500kcal; it would be 2170 - 500 = 1670 kcal. Therefore 1670 kcal is the target in this example to losing 1 lb per week.
