When the IIFYM (If It Fits Your Macros) diet exploded in popularity, it brought with it the idea that you could eat anything so long as you met your daily macronutrient intake. For a lot of people, this meant indulging in fried chicken to meet protein and fat needs and eating Pop-Tarts for reaching that carbohydrate goal.
A diet of junk food and the claim that you can still reach your fitness goals is based on the cliché that a calorie is just a calorie. Recent studies are showing that is not the case. Let’s take a look at what the science says about the importance of the quality of the food you eat, and how the keto diet stacks up for weight loss.
Food Quality Matters for Weight Loss
For many years, the dominant idea was that so long as you burn more calories than you consumed, you could eat whatever you wanted. However, one study from the New England Journal of Medicine found that food quality – not the number of calories – was the most important factor in determining long-term weight loss success. 
What determines a high-quality food compared to a low-quality food, and how you can you tell the difference?
High Quality vs. Low-Quality Foods
The Healthy Eating Plate that is provided by the Harvard School of Public Health states that high-quality food is unrefined and minimally processed. This usually includes foods that natural and organic such as the following:
Fresh vegetables and fruits
Healthy and natural sources of fat such as coconut oil
Healthy sources of protein such as a chicken breast
On the other side of the spectrum, we have low-quality foods, and this is going to include the following:
Highly processed such as snack foods
Sugar-sweetened such as sweet beverages (e.g., iced tea)
Refined grains such as white bread
Refined sugars such as what you’d find in candy
Trans fats (usually found in processed snack foods)
Foods that spike your blood sugar or high-glycemic foods (e.g., white potatoes, soda, etc.)
Quality of a Keto Diet for Weight Loss
When followed responsibly, the ketogenic diet is focused on high-quality foods, and it has been shown to be extremely effective for weight loss. There are two primary reasons for this:
Once you enter a state of ketosis, your body taps into stored fat as a fuel source, not glucose (carbohydrates). This has been shown to accelerate fat burning. One study found that subjects using a keto diet for 24 weeks had a dramatically reduced body weight, body mass index, level of triglycerides, LDL (bad) cholesterol, and blood glucose. 
Also, the ketogenic diet regulates your hunger hormones more efficiently. Studies show that ghrelin, the hormone that triggers hunger, stays in normal ranges and does not increase while leptin, the satiety hormone, stays elevated. In other words, you’ll always feel satisfied on a keto diet.
