Johnston's 25-pound weight loss caught many of her fans' eyes. To that end, Johnston let everyone know exactly how she managed it in such a short amount of time by tagging her post "#optaviaworks." She was also quick to point out it definitely wasn't a sponsored post.
Additionally, according to US News & World Reports, Optavia ranked 27th out of 35 diets, as per their panel of experts. However, it came in second for weight loss overall. The magazine further noted that the diet is nutritionally sound and doesn't involve counting carbs, points, or calories, which is what worked for Johnston.
The Optavia diet is strict in general, though, which might prove difficult for certain people to adhere to, as the food is bars and powdered "just-add-water" products. Clearly, Johnston was determined to make a change, and the Optavia Diet suited her lifestyle. They make their own range of products, similar to WW, which are also reasonably priced, comparatively speaking. Regular exercise is also required, with the main aim of the diet being to make users more confident and comfortable while making healthier choices overall.
