The carnivore diet has intrigued me but I really like vegetables, so I went with the paleo diet, I lost 100lbs in one year, felt way better so I Started lifting weights during the week and Mtn. Biking and hiking on the weekends and have maintained a 75lb weight loss for 4 years. It’s very sustainable and don’t see myself not eating this way in the future, the benefits have been too great. I do believe weight loss is in the kitchen and fitness is in the gym (or trail, etc…) It’s mostly meat and vegetables which I like so it’s not hard, you just have to decide that’s the rule. I do sway towards the beers and like some bourbon occasionally, but getting away from eating sugar, grain (I know, beer and bourbon have both of that…), processed food, etc has made the biggest difference. I always bring my lunch to work, usually a salad with meat leftover from dinner and nuts and hard boiled eggs for a snack. It also makes it very hard to eat out at restaurants when cutting out the non paleo stuff which is great also for the wallet, maybe once or twice a year which is usually a lettuce wrapped burger when we’re traveling or something. I have been thinking about doing the carnivore thing for a month for the hell of it just because it’s interesting to see what changes.
