Whats trending now? Courtney Kassis 90-30-50 diet.

The registered dietitian says she created the plan to help with weight gain associated with Hashimotos thyroiditis after she received a diagnosis for the autoimmune disease.

What is Hashimotos thyroiditis?

This autoimmune disease causes your body to attack its own thyroid tissue, leading to inadequate production of thyroid hormone. In addition to weight gain, it can cause symptoms such as fatigue, joint pain, constipation, intolerance to cold, depression, and skin and hair changes.

Although this diet was formulated by a dietitian, TikTok tends to spawn many less-than-healthy trends. Thats why Healthline spoke with other nutrition experts to weigh in on this plans effectiveness and highlight any potential drawbacks people should consider before following it. What is the 90-30-50 diet?

To understand what the 90-30-50 diet is, we need to talk about what those three numbers in the name mean.

Trista Best, MPH, RDN, LD who is a Registered Dietitian Nutritionist at The Candida Diet, an Environmental Health Specialist, and an Adjunct Nutrition Professor told Healthline this approach requires dieters to hit three daily targets: 90 grams of protein, 30 grams of fiber, and 50 grams of fat.

Following the 90-30-50 method does not create a calorie deficit as most diets do, she added, but focuses rather on consuming a significant amount of these three nutrients.

Best explained that eating protein helps the body repair muscle tissue, preserves muscle, and improves satiety.

Building and preserving muscle during weight loss is essential to keeping metabolism high as lean muscle burns calories at a high rate, she said.

According to Best, the diet recommends fiber because it supports a healthy gut, increases satiety, and helps balance blood sugar.

Finally, she said, getting plenty of healthy fats aids in nutrient absorption, energy, and hormone regulation .

This combination of benefits can aid in preventing overeating and fat storage, said Best. Is the 90-30-50 diet effective for weight loss?

Shelley Balls, MDA, RDN, LDN a Registered Dietitian Nutritionist for Consumer Health Digest said the diet should be very effective for weight loss, echoing what Best said about protein helping to retain muscle mass, thus keeping your metabolic rate high.

Consuming more protein throughout the day will help you feel more satisfied and help you make healthier food choices, she said.

Dietary fibers ability to help you feel full faster and keep you full longer is also beneficial to weight loss, per Balls.

She additionally noted that the anti-inflammatory effects of eating healthy fats can help promote weight loss.

Studies show when saturated fats are replaced with healthy fats, LDL cholesterol levels decrease, waist circumference decreases, and other health biomarkers improve, said Balls.

They can also help with satiety and prevent blood sugar spikes. She noted that both of these will help you with your weight loss goals.

Best, however, pointed out that while the diet may be effective for weight loss, it may not be sustainable in the long run.

This is primarily due to the rigidity required in eating that may cause some to feel overly restricted, she said. This might lead to rebound weight gain once the plan is stopped. Are there any health risks associated with the 90-30-50 diet?

There are some potential issues with this diet since it doesnt address the unique needs of every individual.

Individual macronutrient targets may not be met through this method depending on the degree of activity, health conditions, or the elderly, said Best.

Balls additionally pointed out that if you are not very active, this amount of protein could be too high for your needs.

Those with kidney disease may also want to talk to their doctor before consuming this much protein, she advised.

Even if you dont have kidney disease, the Academy of Nutrition and Diet suggests that its a good idea to speak with a Registered Dietitian Nutritionist before starting a new diet. They can help you understand whether a particular dietary plan is right for you. Takeaway

This diet emphasizes eating 90 grams of protein, 30 grams of fiber, and 50 grams of healthy fats every day.
