Bad cover art. Keto is the single best way to lose weight and permanently keep that weight off. I can literally eat 5 full plates of food every day in a single meal since I do omad as well. And I haven't changed my body fat content in 6 months.
That's not to say you can't lose weight on a vegan diet. That works too as long as you aren't eating refined sugar and pastries all the time. Keep the carbs and the fat away from each other, and you'll lose weight.
The cover art should actually be French fries, a burger, steak and potatoes, risotto, or any other food that is carb + fat.
