As a nutrition and fitness expert, I understand the intricacies of weight loss and the role of dietary fats in the process. The notion that you should consume less than 20 grams of fat per day to lose weight is outdated and not supported by current nutritional science. In fact, a balanced approach to fat intake is crucial for weight loss and overall health.

Fat is an essential macronutrient that provides energy, supports cell growth, protects organs, and is necessary for the absorption of fat-soluble vitamins. It's also important for hormone production and brain function. The key is to consume the right types of fats and in the right amounts.

### Types of Fats
There are different types of fats, and not all are created equal:
- Saturated fats: Found in animal products and some plant-based sources like coconut oil. In moderation, they are not harmful, but excessive intake can lead to health issues.
- Unsaturated fats: These are considered healthy fats and are found in foods like avocados, nuts, seeds, and olive oil. They help lower bad cholesterol and have anti-inflammatory properties.
- Trans fats: These are artificially created fats found in some processed foods. They are harmful and should be avoided.

### Recommended Intake
The American Heart Association suggests that fats should make up 25-35% of your daily calories. For someone aiming to lose weight, this percentage can be adjusted based on individual needs and goals. Here's a simple way to calculate your daily fat intake:
1. Determine your daily calorie needs based on your goal weight. For example, if your goal weight is 120 pounds, multiply by 10 to get 1200 calories per day.
2. Calculate the fat calories by taking 25-35% of your total daily calories. For 1200 calories, this would be between 300-420 calories from fat.
3. Since fat contains 9 calories per gram, divide the fat calories by 9 to find out how many grams of fat you should consume. For 300 calories, this would be approximately 33 grams of fat per day.

### Macronutrient Balance
It's also important to consider the balance of macronutrients. Carbohydrates should be kept at 100 grams or less per day if you're trying to lose weight, but this is not a one-size-fits-all approach. The quality of carbohydrates matters; focusing on whole, unprocessed foods like fruits, vegetables, and whole grains is better than refined sugars.

### Individual Factors
Remember that individual factors such as age, sex, activity level, and overall health can influence how many calories and what types of fats you should consume. It's always best to consult with a registered dietitian or nutritionist who can provide personalized advice.

### Conclusion
In conclusion, the idea of consuming less than 20 grams of fat per day is not only impractical but also potentially harmful. A balanced diet that includes a variety of healthy fats, along with an appropriate balance of proteins and carbohydrates, is the key to sustainable weight loss and good health.
