@jawdy it was more so because I dove right in 100% thinking I could do it ...I suggest the moderate approach.
As an example this is typically how my day went
Breakfast- cold porridge made with organic quick oats, chia seeds and almond milk. Let sit 10 min in fridge and then add fresh berries and honey or agave nectar
Snack - I snacked every 45 min or so on raw nuts like almonds and fresh fruit.
Lunch - small salad with vegetables and oil based dressings. Also fruit.
Snack - Again same as other snack period
Dinner - large salad with a ton of veg and fruit with oil based dressings.
Like I said, I felt great and you realize your stomach doesn't require a lot of food at all. We only perceive ourselves to be hungry because a lot of what we eat are empty carbs..
