Hi Rob,
Clearly all your forces training has given you great mind over matter techniques. But you need to eat!
Yes, it can be a bit of a shock at first to come down to 800 calories but you will find that the lack of carbs reduces your appetite and you won’t feel so hungry. But you need to spend your calories in meat and fats to help achieve that satisfied feeling.
However, there is another way. Many of us on the forums don’t count calories, only carbs. So for instance, we aim for a maximum of 50grams of carbs a day. There are no carbs in eggs, meat, fish or butter and oil. So we eat these freely until we are full, no calorie counting. We still lose weight because of the reduced carbs.
So if you are really struggling with the hunger, try just counting the carbs. But you must only eat when you are hungry and stop eating when you are full. Eat mainly carb free food and veg, stil no pasta, potatoes, bread, etc.
Here’s wishing you a more comfortable week this week!
