Everybody can.
I switched to keto diet 9 weeks ago. In Vietnam. Country of carbs: sugar everywhere, rice noodle & tropical fruits. Went through the rough period of sugar cravings.
Then few weeks in Hong Kong, with all French pastries, dim sum, beer, wine and so much good food.
Resisted all of that and went through the no-booze phase.
And now, in Malaysia, land of fried rice, curries and delicious Malay sweets.
But easy. No more tentations. No cravings.
Lost 15 pounds so far and 4 inch of belly. While gaining muscle and be more productive.
