Op to help on the low carb thing,
Here is a typical low carb day
Fried or scrambled Eggs and bacon for breakfast.
Coffee either black or with some cream in it
Tuna or ham salad for lunch, with avocado, onion, salad leaves and low carb Mayo, olive oil if you fancy it on your salad.
Cajun chicken thighs with skin on, broccoli cheese made with cream, and garlic butter mushrooms for dinner,
No pasta, potatoes, fruit, milk, rice, the highest portion of your intake should be fat, the middle protein and the lowest carb.
So if you split your daily intake into three the most amount of anything you eat is fat, hence why you have skin on your chicken, oil on your salad, and butter on your veg,
Carbs you should aim for less than twenty grams a day to start, and remember everything has carbs, even cucumber,
