I put on weight because I was nutrient deficient -

On a vegan diet eating pesticide, insecticide and chemically laden foods ie not organic, I put weight on cos
I had to eat larger quantities of conventionally grown food
to try and get some more nutrients in but it didnt work.
The fruit, veggies, grains, seeds and nuts were nutrient
deficient cos the minerals were not in the soil to start with, so not in the foods. NPK fertilisers sprayed onto veggies etc prevents the plant from uptaking any minerals that are in the soil only absorb the vitamins.
Cooking food depletes the minerals and vitamins available.

I only ever feel nourished and healthy when eating raw
veggies, fruits, nuts and seeds. I had juices and smoothies every day to build up my levels, ate weeds from my garden and foraged wild berries etc. As much organic food as I could afford.

Cooked carbs and oils left me bloated causing inflammation in my system.

14 days on raw juices, salads, fruits, nuts and seeds along with spring water proved it - I lost weight and that puffy face and bloated body look vanished, it was so obvious.

All the carb laden, salty, sugary and processed vegan food
made me feel depressed and lethargic, all the chemical stuff affects the brain. You only notice it when you give it up and eat clean food. Energy levels are high on low fat raw vegan foods.

I eat superfoods - maca, spirulina, goji berries, medicinal mushrooms, wheat grass powder, lucuma, raw cacao, probiotics, fermented cabbage, hemp seeds, coconut oil, etc etc just to feed my body what its missing.
