Fat Isn't the Enemy (But Skipping It Might Be)
Why your low-fat diet might be doing more harm than good.
You’ve been careful for years. You choose low-fat dahi. You skip the ghee on your roti. You avoid nuts because they’re “high in fat.” Your meals are lean, light, and supposedly healthy.
But your joints feel stiff. Your skin is dry no matter how much moisturizer you use. You’re hungry an hour after eating. Your energy dips throughout the day.
What if the problem isn’t that you’re eating too much fat, but too little?
Why Fat Is Actually Essential
Your body needs fat for specific jobs it cannot do without it.
Building every single cell. Every cell in your body is wrapped in a membrane made of fat. Without enough fat in your diet, your body struggles to build and repair cells properly.
Making hormones. Estrogen, progesterone, testosterone, and cortisol are all made from cholesterol, which comes from fats you eat. When you eat very low fat for months or years, hormone production becomes inconsistent. This is why some women on extreme low-fat diets experience irregular periods or worse menopause symptoms.
Lubricating your joints. The synovial fluid that cushions your joints needs fat to maintain its thick, protective consistency. Without adequate fat, this fluid becomes thinner and less effective. Your joints feel stiffer and more uncomfortable.
Absorbing vitamins. Four vitamins - A, D, E, and K - dissolve only in fat, not water. If you eat a salad with carrots (vitamin A) but no fat, your body can’t absorb that vitamin. It passes through unused. This is why people eating very low-fat diets can be deficient in these vitamins even when eating vitamin-rich foods.
Keeping you satisfied. Fat slows down digestion. This means your blood sugar rises gradually after eating and stays stable longer. Without fat, meals digest quickly. Your blood sugar spikes, then crashes. You feel hungry again within an hour and reach for snacks.
These aren’t optional nice-to-haves. These are essential functions. Your body literally cannot perform them without fat.
What Happens When You Eat Too Little Fat
When you consistently avoid fat, your body sends clear signals.
You’re hungry shortly after meals, even substantial ones.
You crave sweets and carbs constantly because your blood sugar is unstable.
Your skin becomes dry, flaky, or dull no matter how much water you drink or cream you apply.
Your joints feel stiff, especially in the morning.
Your periods become irregular or menopause symptoms worsen.
You feel cold often.
Your hair becomes dry and brittle.
These aren’t separate random problems. They’re your body telling you it needs fat.
The Right Fats in the Right Amounts
The solution isn’t to pour oil over everything. It’s to include moderate amounts of healthy fats in your daily meals.
How much do you need?
About 2 to 3 tablespoons of added fats per day. This could look like:
1 to 2 teaspoons of ghee or oil used in cooking your meals
A small handful (about 10 to 12) of nuts like almonds or walnuts
1 tablespoon of seeds like flaxseeds or pumpkin seeds sprinkled on dahi or salad
Plus fats that come naturally in foods like regular dahi, paneer, eggs, or fatty fish if you eat them.
Which fats to choose:
For cooking: Ghee, mustard oil, or any cold-pressed oil you prefer. Use 1 to 2 teaspoons per meal, not more.
For adding to meals: Nuts like almonds, walnuts, or cashews. Seeds like flaxseeds, chia seeds, or pumpkin seeds. These also give you protein and minerals.
In your meals: Regular dahi instead of always choosing fat-free. Paneer in normal portions. Eggs. Fatty fish like salmon or mackerel twice a week if you eat non-vegetarian.
Which fats to avoid:
Trans fats: These are in many packaged biscuits, namkeen, and bakery items. Check the label for “partially hydrogenated oil” or “vanaspati” and avoid those products.
Reused cooking oil: Oil that’s been heated multiple times, like in some street food or restaurants, creates harmful compounds. You can’t always control this when eating out, but avoid reusing oil at home.
How to Know If You’re Getting It Right
Your body will tell you if you’re eating the right amount of fat.
Signs you’re eating enough:
You feel satisfied for 3 to 4 hours after meals
Your skin feels softer and looks healthier
Your joints move more easily, especially in the morning
You’re not constantly craving sweets
Your energy stays steady through the day
Signs you might be eating too little:
You’re hungry within an hour of eating
Your skin is persistently dry
Your joints feel stiff
You crave sugary foods constantly
You feel tired and foggy
Signs you might be eating too much:
You feel heavy or sluggish after meals
You’re gaining weight despite eating healthy otherwise
Your digestion feels slow
Start Simple
If you’ve been avoiding fat, start adding small amounts this week.
Add 1 teaspoon of ghee to your dal or rice. Have 10 almonds with your evening chai instead of biscuits. Sprinkle a tablespoon of seeds on your morning dahi. Choose regular dahi instead of fat-free a few times this week.
Notice how you feel. You’ll likely find you’re less hungry between meals. Your skin starts looking better within a week or two. Your joints feel less stiff in the morning. Your energy feels steadier.
The goal isn’t to eat as much fat as possible. It’s to eat enough so your body can do what it needs to do. Not too little. Not too much. Just enough.
Fat isn’t the enemy. Avoiding it completely is.
