I am now following a healthy eating cookbook by a body coach. I am doing an HIIT training routine he has suggested for 20 minutes, 4 times a week. The confusion I have is the amount of fat I am consuming following his cookbook. His logic is to have carbohydrates only after the HIIT session and food with healthy fats the rest of the time. He suggests eating healthy fat helps to lose weight? How is this possible? Can someone explain this to me please? Having a full avocado with bacon for breakfast, is that healthy with the amount of workout I do?
To lose weight: Calories In < Calories Out
Eating Fat does not make you fat. Eating too much makes you fat.
The specific fat/carb/protein breakdown of those calories influences your energy levels and rate of muscle growth (amongst many other things) but does not directly affect your weight loss. Again, to lose weight: Calories In must be less then Calories Out.
You eat more satiating (filling) foods by cutting carbs in favour of fats. You get more food and feel more full eating that way. Cutting carbs and increasing fat to counteract the calorie change is a fine way to lose weight provided you remember, Calories In < Calories Out.
