Jenna shared some great tips to help dieters stay on track. She began her weight loss using clean eating and meal prep. She meal preps two days at a time instead of for the entire week. By doing this, it keeps her meals fresh and exciting.

She also found smart replacements for her sweet tooth cravings. Instead of ice cream and candy, Jenna eats a bowl of fresh cut-up fruit with whipped cream and sometimes dark chocolate drizzle on top. It satisfies her cravings, yet keeps her on track.
