Is it possible to estimate the calories from the cooked food in my home?

It is possible to estimate the calories, but it is time consuming, and expensive and further the results are very inaccurate.
I am against calories counting and it makes you only mad. Many food ingredients are mixed in different proportions in our food and so it is also very difficult to calculate the calories of a food from the individual food calories chart.

Watch the amount of food, the variety of food and by doing so you can find out the optimum for you and your family. Consult a good dietician and it helps a lot to understand several things about our foods.

You are that what you eat.

Is canola oil a rapeseed oil?

Canola oil is genetically modified rapeseed oil which is free from the pungent smelling of euric acid and it is patented in Canada.
Rapeseed belongs to the family of mustard. Mustard oil contains erucic acid which is dangerous for infants and very small children. Therefore, it is not allowed to use as spice oil in those countries.

The long term health effects of genetically modified food are not established clearly and so you must be very careful. Majority of the countries in our world has yet banned genetically modified food.

Is taking more milk and milk products correct?

Milk and milk products are healthy if we eat them in small quantities.
In Western countries they used to take too much milk and milk products which cause a lot of problems with calcium metabolism. Too much of protein makes more calcium to excrete from your body and the same is the case with the sodium present in cheese. The milk industry is powerful and their advertisements make us think like this. Moreover their lobby is very big.

Too much of milk and milk products make one very tired. I have asked women to sacrifice milk and milk products for 14 days to show them that excess food based on milk make them very tired. The results are always good. 60% of the world population have problems with milk and milk products.

Milk has also cholesterol.

Animal food: Can you tell me the amount of cholesterol present in shrimp?

All animal food including fish contains cholesterol.
100 gram of edible shrimps contains 140 mg of cholesterol, if you are healthy, now and then is good, but if you have cardiovascular problem, eat rarely.

It is not necessary to avoid animal food with cholesterol. Cholesterol is very much necessary for your health. Your liver produces everyday 1.5 to 2 g cholesterol.

I am very careful with my food, fruits and vegetables, low fat milk, cereals and swim every day and go to gym, but I am not losing any weight...

What you eat is good but I have no information about your weight, height, how much and when you take your food and also how much water you drink.

My experience is if you do more exercise and reduce your food intake, your metabolism slows down very much and only few calories are burnt. Eat normally, drink enough, 3 to 4 litre of water, more physical activity and have patience for few weeks. Your body gets more calories, more physical activity and now burns more calories and your weight will come down.

The side-effects of some of the medicines also increase your weight and in this case you can eat less but your weight will not come down but can go up. A personal consulting with your doctor and dietician can clear this situation. The minimum effective dose of the medicine must also be found out by your doctor; otherwise the chances are very bleak.
