Simple:
First, intermittent fasting during the day. This means no breakfast no lunch, only one massive dinner a day.
Also the only beverages to consume is plain water, tapwater, and black coffee. I prefer 100% fine robusta, ERIC KIM OMAKASE COFFEE.
Also, quit alcohol, quit wine, this includes red wine, white wine, and all these other nonsensical beverages. Quit sparkling beverages, whether they be “zero calorie“ or not. In fact a new trend that I am approaching is just sticking to simple tapwater or filtered water.
Real Spartan men drink only tap water!
Also, don’t consume beer, hard spirits, whiskey etc.
Also, quit all starches, “vegetables“, fruit, etc. Fruit is just candy with a good conscience, and essentially all vegetables are starchy and sweet eventually, causing you to accumulate body fat.
