Lena Dunham's "Trump Diet" Is a Really Bad Idea

Her weight loss is real, but we simply can't recommend an eating plan based on half-eaten croissants and packs of baby food.

If you follow Lena Dunham on Instagram, you may have noticed she's looking slightly more svelte these days. Unfortunately, it's not because she's adopted a cutting-edge new diet plan or exercise regimen. And her new figure, she's revealed, comes from a very unexpected source: President Donald J. Trump.

This week, the "Girls" star told Howard Stern: "Donald Trump became president and I stopped being able to eat food. Everyone's been asking like, 'What have you been doing?' And I'm like, 'Try soul-crushing pain and devastation and hopelessness and you, too, will lose weight.'"

Yikes. After her comments coursed through social media, she decided to share exactly what her day-to-day diet looks like in an Instagram post:

Now, it should go without saying that cold green tea, half-eaten croissants, and squeeze-packs of baby food aren't exactly great pillars of a healthy meal plan. But, in weight-loss terms, this is guaranteed to backfire. As scientists have revealed time and again, most notably in a major study published last year in the journal Obesity, people who drop weight through crash diets will be invariably gain it all back (and then some) in the long-term. In some cases, it can cause permanent damage to your body.

The reality is that when you cut so many calories from your diet, your metabolism slows to a crawl. (Scientific term: "metabolism adaptation.") Many of the test subjects in the aforementioned study emerged with irreparably damaged metabolisms after their diets—their bodily levels of the hormone leptin, a key regulator of hunger, returned to only 60 percent of its original levels.

To be sure: those diets are quite extreme compared to Dunham's grief-based fast. And we're encouraged that she'll rebound just fine. (After all, she added the good news that she's "still rocking a BMI above [her] doctor's recommendation, despite months of this.")

To her credit, Dunham has always maintained a healthy sense of humor about her body, especially as the subject of her weight has become a topic of discussion for both fans and haters alike. We applaud her for not recommending that anyone else try this.
