Tampa, FL

Gabby + Jessica changed my life!! I seriously cannot recommend 7.7 Nutrition more highly – they are the absolute best and really go above and beyond to get to know you, help you, listen to you, and make you feel like you are making great progress no matter how much or how little it really is. I was so afraid to start the journey with them because I felt ashamed that I needed to get help for my weight, but they always made me feel welcomed, important, and encouraged me to keep going and making progress. Gabby and Jessica helped me lose almost 40 pounds in about 4 months with very little exercise and I cannot thank them enough for helping me get my confidence and life back!!!

W Bloomfield, MI

This team is amazing. Laura helped me figure out a plan that worked with my lifestyle. I originally only wanted to lose weight by dieting however I was able to walk away with a whole new outlook on nutrition. Taking the food sensitivity test identified which items to stay away from and my body has thanked me by literally shedding the weight almost immediately (could notice the difference within 2 weeks)! 10/10 would recommend

Novi, MI

7.7 nutrition has the most knowledgeable and genuine team of nutritionists. They are very thorough and take the time to get to know you personally and adjust to your needs. They don’t provide “cookie-cutter” diets, they are customized for you personally. I love the accountability their programs provide. Not only that I’ve had FANTASTIC results. I’m sleeping better at night and my energy has substantially increased which is where I was lacking the most. Highly recommended!!
