Finn Wolfhard is a Canadian actor most famous for his role as Mike Wheeler in the TV show Stranger Things and for voicing Pugsley in The Addams Family (2019).

As Stranger Things came out with season 4 this year, Wolfhard fans noticed his dramatic weight loss.

Having successfully trained over a thousand people to lose weight for over a decade, I observed that Wolfhard’s so-called “transformation” didn’t look healthy.

To examine this further, I teamed up with a dietician and studied Wolfhard’s physique over the years.

Here’s what we found about the Finn Wolfhard weight loss journey.

The Finn Wolfhard Weight Loss Journey

Wolfhard was only 13 years old when he started playing Mike Wheeler in season 1 of Stranger Things.

He wasn’t particularly lean or skinny but seemed to have the physique of an average 13-year-old.

In fact, based on his action scenes (how he ran, jumped, and engaged in other physical activities), Wolfhard seemed energetic and fit.

But what concerned his fans the most was the fact that he got skinner with every season of Stranger Things — to the point where he looked quite unhealthy.

Our dietitian said that he looked like someone who frequently skips meals.

While there were multiple speculations regarding Finn Wolfhard’s weight loss, we now know that it stemmed from bad eating habits [1].

“I still eat like a four-year-old child, which is not a good thing when you’re constantly traveling and feeling crappy because of your diet.”

Diet Routine and Principles

Healthy diet with protein rich and fat rich foods

Since gaining muscle is the key principle here, you’ll need to focus on high-protein foods for muscle gain and a high-fat diet.

You needn’t eliminate carbs because they can provide energy for workouts.

As a personal trainer, I can say from experience that a focus on eating high-quality sources of protein is the key to a leaner body, which research at WebMD confirms [2].

Such as:

  • Lean beef
  • Seafood
  • Poultry
  • Eggs
  • Pork tenderloin
  • Milk, cheese, and yogurt
  • Beans
  • Certain brands of protein powder

3 Important Weight Loss Pointers

We’ve seen how you can lose weight in an unhealthy manner, as in the case of Wolfhard.

So, here are some tips to help you lose weight, build muscle, and get a balanced physique without compromising your overall health.

1. Lose Weight Safely

If you’re planning on losing weight, make sure you don’t rush it. It’s unsafe and could potentially lead to health problems.

A safe rate of weight loss is 1–2 pounds per week [3]. This assures you’re getting enough calories every day while shedding fat.

2. Build Muscle Alongside Weight Loss

While losing weight, it’s also important to build and gain lean muscle mass and strength. This will ensure you have a well-balanced physique and enough strength to perform basic athletic movements.

3. Eat Healthy Food

Eat a healthy diet to ensure you have enough calories to push through your workouts. Ensure that you’re getting in all your macros as well.

It's a reminder that weight loss, often viewed through a physical lens, also carries profound mental and emotional dimensions, particularly for those constantly in the spotlight.
