Yes, literally by eating less. You can lose weight on a diet of pure granulated sugar.

For the purposes of weight loss, exercise is absolutely overrated, especially the low intensity cardiovascular type that most individuals trying to lose weight engage in. The actual number of calories burned for the mental effort/discipline is garbage and that effort would be better spent on better dietary discipline.

High intensity training and weightlifting have better results due to increasing metabolic rate for a long period after the activity, but the key to weight loss is diet.
