IF:45 is for you if:

  • You've tried fasting on your own and you didn't see results (weight loss and body composition)
  • You want to learn how to fast in a way that's healthy and sustainable
  • You need accountability
  • You don't know how to use macros (protein, carbs, and fats) to achieve fasting success
  • You want to balance blood sugar levels
  • You want to eliminate brain fog and increase energy

What if I told you there is a flexible way to lose belly fat, balance blood sugar levels, increase energy, and eliminate brain fog. And what if I told you there was a program out there to teach you EVERYTHING you need to make intermittent fasting a permanent and healthy lifestyle?

Most intermittent fasting programs are designed for men. As a midlife woman you need a program specifically for you and your needs.

IF:45 is what you need for success.

The foods you choose in your feeding window are critical. You will be successful when you know how to eat the right combination of protein, carbs, and fats. That is why there is a 21 day meal plan with science backed recipes.

Blood Sugar Balance

Research indicates that IF lowers insulin levels and increases insulin sensitivity allowing you to lower blood sugar levels and reduce body fat.

Metabolic Flexibility

During prep week we will work on moving you away from addictive carbs and increasing satiety with protein and healthy fats. The goal is for you to switch from being a constantly hungry carb-burner to a metabolically efficient fat- burner who can successfully fast.


Maybe you've tried intermittent fasting before and were not successful. The key is mindfulness. The emotional draw to food is strong. Dr. Tara Gunther will be helping you overcome negative thought patterns and emotional eating.

Meet Your Coaches

Carol Covino

Carol Covino has helped thousands of women to lose body fat and to tone and strengthen their bodies with nutrition and exercise.

In her forties she was a "skinny fat" burned out marathon runner who exercised obsessively.

At age 50 she decided to do a figure bodybuilding show to transform her body. Through the process she learned about nutrition and weight training and went on to coach over a thousand women to reach their fitness goals.

Although the bodybuilding lifestyle taught her about exercise and nutrition, it was actually hurting her health. She was eating 6 meals a day in her off season with a cup of white rice at every meal. At the end of the day she was bloated and inflamed!

She discovered the benefit of intermittent fasting for reducing body fat, balancing blood sugar, and becoming insulin sensitive. She realized the small "mini meals" were skyrocketing her blood sugar and damaging her metabolism. She learned to implement intermittent fasting in a safe, effective way.

Carol Covino is certified in fitness nutrition and the IF:45 method under Cynthia Thurlow. She is also a female metabolism and menopause fitness specialist with over 12 years experience. Carol is currently working on her Functional Medicine Coaching certification.

At age 62 Carol is committed to helping you achieve metabolic health with the IF:45 method.

Dr. Tara Gunther

Along with being a licensed Clinical Psychologist, Dr. Tara Gunther is also a Health and Wellness Coach after completing the Integrative Health Coach Certification through the University of Arizona Andrew Weil Center for Integrative Medicine.  She is also a certified coach in Cynthia Thurlow’s Intermittent Fasting Masterclass IF:45.

Tara’s deep fascination of the mind-body connection drove her decision to place an emphasis on the study of health psychology in both her master and doctoral degrees in Clinical Psychology.  Having later completed programs in physician leadership at both T.H. Chan School of Public Health at Harvard and Bloch School of Management at the University of Missouri-Kansas City, she worked extensively in the field of primary care behavioral health integration.  As a result, she developed expertise in working with patients in Sleep Medicine, Gastrointestinal Disorders, Diabetes and Primary Care.  Despite the range of chronic illness conditions, Tara noted the common thread of metabolic dysfunction amongst many of her clients, who often struggled with more than one chronic health condition.  As a health psychologist, she advocated for behaviors that would ultimately help them manage their symptoms and hopefully lead to a more fulfilling life.

When Tara discovered intermittent fasting (i.e., time-restricted eating), she realized how ill-advised her advice had been over the years.  It has mirrored what the medical community believed, that eating 5-6 small meals throughout the day was the advised protocol for most patients to “keep the metabolism burning.”  Once Tara began to research and educate herself on the benefits of intermittent fasting and the incredible impact on our hormones including metabolic flexibility, her practice changed dramatically.  She began not only to change her own lifestyle choices as she navigated perimenopause, but also she began to educate and help her clients understand the benefits of intermittent fasting on mood, weight management, hormone regulation and mental clarity.
