That takes some serious self control as sugar is highly addictive. Check out the book Potatoes Not Prozac which writes about how sugar, and carbs in general affect your hormones, specifically raising your cortisol stress hormone, while at the same time increases sugar cravings. It also leads to low serotonin, beta-endorphin, and melatonin, which is found in people who have cancer and compromised immune systems. Imho, best way to lose weight is to eat a Mediterranean high fat keto diet. Greek salad + steak/chicken + greek yogurt, lots of butter and monounsaturated oils. I'm Mediterranean, and no one in my family is fat, and we have no chronic diseases, and have long longevity. Our dessert is high fat yogurt with some cocoa on it or dark chocolate with nuts. On average we eat less than 50 grams of carbs a day. I personally eat a lot of meat and am pure muscle, with very low body fat. Chuckeye steaks every day. Also, we avoid fructose, as it's poison.
