What does fat look like, exactly? When you think of fat, you may think of body fat (such as your midsection) or dietary fat (such as a juicy, grass-fed steak).
For the longest time, people thought dietary fat and body fat were tightly related. Erroneous scientific studies told the general population that dietary fat lead to weight gain, which caused the low-fat craze of the late 20th century. However, new evidence shows that dietary fat can cause fat loss (not fat gain).
That being said, not all fats are created equal. While healthy fats from avocados, olive oil, and grass-fed meats are part of a healthy, keto diet, other fats should be avoided at all costs. Junk food, including french fries, ice cream, and candy bars are best avoided completely.
To help better understand how body fat and dietary fat work together, keep reading. Plus, you’ll discover what 30 grams of fat looks like from a number of different food sources.
Why Fat Does Not Make You Fat
For the longest time, it was believed that eating dietary fat would increase body fat. After several studies in the 1970s-1980s made a supposed connection between dietary fat and weight gain, increased cholesterol levels, and an increased risk of heart disease, the general United States population switched to a low-fat diet. However, new studies are now debunking these claims.
After two decades of the low-fat diet fads, scientists noticed that a decreased consumption of dietary fat caused a massive increase in the prevalence of obesity[*].
In fact, various studies have found that high-fat, low-carb diets have been a more effective weight loss (and fat loss) tool than low-fat, high-carb diets. Consuming high amounts of dietary fats have been shown to be particularly effective in reducing a type of fat called visceral fat — that is, fat around the abdomen, or belly fat[*].
For example:
- In a six-month study, the effectiveness of low-fat versus low-carb diets were stacked against one another. Those who reduced their carb intake lost three times as much body weight as those who followed a low-fat diet[*].
- In a different study done on 300 people, those who followed a low-carb or Mediterranean diet lost more weight than participants following a low-fat diet. Plus, those following the low-carb diet saw improvements in their triglycerides and HDL cholesterol levels[*].
- In a two-year study done on a high-fat keto diet, the body mass index of patients decreased significantly. In other words, the patients saw a decrease in their body fat percentage while maintaining muscle mass[*].
What Does Fat Look Like? 30 Grams of Dietary Fat
Against popular opinion of the past few decades in the nutrition industry, dietary fat is healthy for you. It’s a macronutrient required by your body to maintain optimal hormone and body function.
Your heart cells run exclusively off fats. Fat cells also help you absorb beneficial vitamins and minerals. Triglycerides, cholesterol, and other fatty acids store energy, keep you warm, and protect your body’s vital organs[*].
But not all dietary fats are the same. The healthy fats from a grass-fed steak will contain more micronutrients compared to greasy french fries from your local fast food chain. Trans fats found in vegetable oils and hydrogenated oils have zero health benefits whereas saturated fats, unsaturated fats, and omega-3 fatty acids all have advantageous effects for your body.

An Infographic: What Does Fat Look Like?
Here are simple, printable reminders to help you remember what 30 grams of fat looks like anytime you don’t have a scale on hand.




Eating Healthy Dietary Fats Does Not Cause Body Fat
For decades, people believed that dietary fat caused body fat. However, there are numerous studies comparing low-carb, high-fat diets to low-fat, high-carb diets that debunk these claims. These studies show that participants who followed a high-fat diet lost more weight than if they were to restrict their fat intake[*][*][*].
Adequate amounts of dietary fat are essential for keeping your organs healthy, keeping you warm, and helping you absorb valuable nutrients. However, when adding healthy fats to your diet, you should know which food sources are best.
When looking for healthy fats to consume, stock up on grass-fed meats, hormone-free poultry, wild-caught fish, eggs, nuts and seeds, and healthy oils. Avoid sugary desserts (like ice cream), starchy side dishes (like french fries), and vegetable oils.

Love the infographics! Also, that you listed the carbs for each as well. It would have been helpful to have the grams of sugar listed too. This will definitely help when I am trying to decide what meal options are available. Thanks!
This is so helpful!
Very helpful information! Thank you!
Very helpful still having a hard time getting all the facts that I need in
Thank you ????
I ABSOLUTELY LOVE THIS WEBSITE. I FOUND IT ABOUT 2 WEEKS AGO AND I CAN’T STOP READING THESE ARTICLES. LOVE IT. THANK YOU FOR EVERYTHING THAT YOU DO!!!
Most helpful info I have read thus far. Thank you.
Helpful, except two avocados weighing 210 grams are likely very small avocados and combined likely have net carbs between 6-9.
A typical single weighs about 200 grams.
Hi Jason, it’s 210 g each.
This is golden, I was literally sitting at my desk freaking out because I have about 300 calories left in the day, 40 grams of fat and 20 grams of protein to get through and I had no clue how to achieve that. I did a lot of googling and then found this. Actually seems like all my concerns lead me back to this website. Pure gold.
