Here are some key components to aid in weight loss:
Regular cardiovascular exercise, 56 minutes, 3-4 times per week. This will help you keep weight off and keep your energy levels high.
Healthy eating, including portion control, lean protein, whole grains, and lots of fruit and vegetables. Staying hydrated is also essential especially if you're active. 8-10 8oz. glasses of water per day are recommended.
And most importantly, sleep! The average person needs 7-8 hours of quality sleep per night to help the body repair itself, and to recharge the mind and the central nervous system.
