Many people say that a meat based diet is a “high protein” diet. It really isn’t. The following is a list of foods that comprise 90+% of everything I eat. The % that follows each food is the % of calories that come from fat. Obviously most of calories come from fat, I’d guess around 70% on average (ground beef patties with cheddar cheese slices on them is my most common meal).  This table is also helpful on zero carb (a popular meat only diet) as the most common treatment of constipation is “eat more fatty meat” and the advice for the opposite problem is to “eat more lean meat”  If there are foods you’d like to know about this website shows the % of calories from fat for 1000s of foods https://www.fatsecret.com/calories-nutrition/ .
