Hi Linda
Thanks for your question. To calculate calories in your instance, you need to use a formula to calculate your basic metabolic rate – the energy needed for your body to function. You haven’t provided, however, the data needed for this calculation (your height, weight, and age).
Counting calories, nevertheless, does not equal good nutrition or weight loss – eating less calories could lead to malnutrition. There are “empty calories” that supply only few nutrients and can cause quick weight gain (like refined products high in sugar, refined grains and low in fibre) so instead of counting calories, try focusing on healthy calories!
Very low calorie foods are vegetables. You could find dark green vegetables especially useful since they are rich sources of vitamin K, vitamin A, magnesium, and calcium that can support bone health and recovery after your operation.
You could try to include them into your daily regime: have a bowl of fruit before your breakfast, green soup (made of kale, spinach, broccoli and sweet potato) before your lunch and a vegetable salad with some seeds before your dinner.
In this way, you significantly increase your intake of nutrients vital for bone health and healing and reduce the intake of calories overall since you will fill up on vegetables and fruit first. This way, you do not go hungry and still reduce your food intake.
You can also try reducing the plate size – people find they eat less when they use smaller plates. If you include fruits and vegetables before your main meal, you should eat less anyway but it is also easy to overeat. Sticking to a small plate size could help you to manage this.
Try to eat protein (meat, fish, shellfish, eggs, pulses, nuts) with each meal which could help you to reduce appetite. Protein can stabilize sugar levels after a meal which leads to less cravings in-between meals and help to burn more calories.
Reduce the size of carbohydrates on your plate especially refined ones like white rice, white bread and white pasta and replace them for nutrient and fibre rich whole, unrefined foods like pulses, whole grain bread/pasta and brown rice. If you include fibre-rich foods in your diet, they can significantly reduce your hunger and improve your chances of weight loss.
To sum up, eat vegetables as a starter before lunch and dinner, use smaller size plate, and fill up half of your plate with protein rich foods (meat, fish, eggs), and then unrefined carbohydrates (whole grain bread/pasta, brown rice, pulses etc.) of the size of your palm only, and add some healthy oil (like Extra Virgin Olive oil), nuts and some more cooked vegetables to fill you up!
It goes without saying though, that reducing your sugar and fast/processed food intake is vital for your weight goals.
You may wish to visit a Nutritional Therapist to address your exact needs to make sure that you can support your body during the healing period and improve bone health with appropriate sources of nutrients.
Good luck!
