From cooking oil to carbs, protein, fats and fibre, home-cooked food can provide you the perfect balanced diet you need for good health and weight loss.

3. Carry home-cooked food when travelling or going out

There are times when you simply cannot avoid eating out. But, you can definitely work on reducing the number of times you have to eat out. Meal prepping can help you in this case. On a day when you know you have to travel or not be at home or your workplace, carry your food with you. This will help you keep up with your weight loss diet and also avoid eating food which is most likely to be cooked in reheated oil. You can also opt for fast food that involves less use of oil like salads, dosa and idli.

4. If you have Alzheimer's, diabetes, high blood pressure, heart disease or any other disease running in the family, it gives you all the more reason to avoid reheating cooking oil. It is going to contribute to more inflammation in conditions that are already inflammatory in nature.
