Here comes yet a new viral trend from TikTok that promises to be an effective weight loss diet, the main pull factor being that you don’t have to really restrict certain foods, but consume a variety of healthy ones in a specific quantity. So could the 90-30-50 diet plan actually be worth checking out?

The weight loss industry sure can be a saturated market filled with fads and trends, but sometimes an effective strategy is born. In this article, we try to find out if the 90-30-50 diet plan is one of them – breaking down how it works and if it’s an effective and safe method for losing weight!

What is the 90/30/50 Diet Plan?

Created by Courtney Kassis, RD, LDN who is a nutritionist and influencer, this diet simply requires you to consume 90 grams of protein, 30 grams of fiber, and 50 grams of healthy fats every day. Kassis claims to have dropped 15 pounds and lost 2% body fat in just two months since having gone on the weight loss diet. Now, she declares that she’s lost 55 pounds postpartum and put her Hashimoto’s into remission:

Kassis also explains in another video that she does not believe in restrictive diets, and that after fulfilling the 90-30-50 quota by prioritizing protein, fiber, and healthy fats, carbs come in. However, it’s good for them to come from whole, unprocessed, and low-glycemic sources.

Can You Actually Lose 15 Pounds in 2 Months?

As this diet majorly focuses on protein, it can definitely contribute to weight loss. A study by The International Journal of Obesity showed how a 20% increase in protein intake led to 50 percent lower weight regain. Protein, healthy fats, and fiber-rich foods all leave you feeling fuller and increase satiety. If an individual were to focus on these foods and naturally eliminate processed and sugary food and drinks, losing 15 pounds in 2 months can be a possibility. This balanced diet should also be combined with effective workouts for weight loss.

What are the benefits of the 90/30/50 Diet Plan

  • As a result of a high-protein diet, there is an increased metabolic rate since protein digestion requires more energy, burning more calories even while the body is at rest [1].
  • The whole foods and nutrients consumed are also highly recommended for muscle building, especially protein and healthy fats. So say hello to muscle growth and lean muscle mass with your new dietary plan.
  • Fiber is a major player in improving gut health and improving digestion.
  • Healthy fats protect you against heart diseases, diabetes, and other chronic diseases [2]. Healthy fats also promote metabolism and support fat-burning processes.
  • Protein helps to balance blood sugar levels and regulate hormones [3].
  • The recommended diet rich in micro and macronutrients, protein, fiber, and other healthy foods helps keep cravings at bay and increases satiety [4]. This automatically will help you lose weight and have sustainable weight loss, along with all the other health benefits brought on by vitamins, minerals, and antioxidants.
