Why Fad Diets Go Viral (and How to Spot the Red Flags)

By Lizzie Streit, MS, RDN, LD

A one-week diet that makes you lose 10 pounds, a juice cleanse that rids your body of “toxins,” or a weight loss meal plan with the same food for every meal. Sounds appealing, right?

Quick fix diets claim to offer what almost everyone wants: quick results. In reality, if it sounds too good to be true, it probably is. While it’s common to feel tempted by a fad diet, achieving sustained weight loss is a much less flashy and more long-term process.

Keep reading to learn about why quick fix diets go viral, how to spot red flags, and what strategies work instead.

Viral Nutrition

Today, people commonly consume information in short video clips and brief statements. Social media promotes sensationalized content and bold claims that drive clicks and engagement. This media landscape is a breeding ground for quick fix diets. Consumers are drawn to dramatic promises of better health and/or weight loss for little work. As more and more people flock to these claims, fad diets and food trends go viral.

Before trying the latest fad, it’s important to assess the information for credibility. Red flags include using inflammatory language, making bold claims based on a single study, not including citations, and encouraging complete restriction of certain foods. You can also research the person making the claims to see if they have a degree from an accredited university that’s relevant to the topic or credentials from the Commission on Dietetic Registration (CDR).

What to Do Instead

As tempting as quick fixes may be, the results often fall short of what’s promised. They may even come with risks, such as dehydration, fatigue, and nutrient deficiencies, especially if they encourage food restriction or eliminating food groups.

Instead of trying the latest fad diet, only to be discouraged with the results, reframe your thinking to view weight loss as a long-term process. Start with small changes, such as reducing soda intake, adding protein to each meal, and eating vegetables with dinner. Once you accomplish these goals, build on your progress with more changes to your diet and the addition of regular physical activity.

Another helpful strategy is reducing the everyday barriers that make healthy eating harder to stick with. Planning meals, grocery shopping, cooking, and portioning balanced plates all require time and energy — which is one reason many people end up turning to quick fixes instead of building sustainable habits.

Consider working with a registered dietitian for guidance and support. While tips from dietitians and other nutrition experts on social media can be helpful, you may find that one-on-one counseling is a better option at first to figure out what’s best for you and create a personalized 1200 calorie meal plan. Celebrate small wins, and be sure to track your progress! Even though the journey to your success may be longer than what a quick fix diet promised, it will be more sustainable.

For many people, having balanced meals already prepared can also make it easier to stay consistent with healthy habits. When meals are portioned with the right balance of protein, fiber, and nutrients, it removes much of the guesswork and decision fatigue that often derail progress.
