Hi
@KIZZY I understand that you need to lose some weight, but that you have health problems that make it har to get exercise. Don't worry, it is possible to lose weight just by doing the same normal amount of activities that you already are doing. It works for over 50% of people, just by cutting down hard on the amount of sugary and starchy food eaten. Even without consciously cutting Calories.
Just cut the carbohydrates and replace them with more Protein and more traditional fats (not Vegetable Oil) by traditional I mean fatty fish, fatty cuts of meat, butter, double cream rather than milk, eggs, cheese. Cook with butter/ghee, or lard or coconut oil. Use Olive Oil on salads rather than rapeseed or sunflower or corn oils.
It is carbohydrates that make most people fat, especially if those carbs are mixed with seed oil fats in processed food. But natural fats mixed with protein don't have that effect - instead we lose weight, lower blood glucose, have more energy, feel less hungry plus lots of other benefits!
