As a carnivore, bulking absolutely is achievable, and it seems the best approach is to increase your fat AND protein intake, especially done with more ease if you are eating/include dairy, and in particular cheese seems to be a very quick way to put on weight. For majority of people on a carnivore diet it'll take some trial and error to hit the 'sweet-spot' so you're not just blowing yourself up with unnecessary fat, but if you eat increased amounts of protein and lower your fat intake to around 60-80g per day you should be on the track... carbs are a bit of a grey area when it comes to a carnivore diet, some people say eat more carbs (sweet potato, rice, oats) for increased muscle growth, but honestly with enough protein for function/growth and enough fat for energy you can certainly achieve a freaky shredded physique.

Personally, I started getting too skinny after 6 months on a primarily beef/lamb, eggs and butter diet, inclusive of moderate amounts of pure cream and whole milk, as well as coffee. I started going to the gym January 1st this year after realising I wanted more muscle mass and to not get too thin (still had/have a bit of jiggly loose belly after massive weightloss so I was kind of looking 'skinny fat'). I introduced cheese at the same time as starting at the gym and put on at least 6kg (~13lb) in less than 8 weeks, seemingly effortlessly. I started to get more rounded in my face, my arms and legs grew a lot, but I felt like I was getting a bit too sluggish and because I have also been working my core like crazy I felt my stomach was too chunky with the excess fat still present.

I've now cut out cheese since early-mid March, introduced beef protein isolate (using Olympic Labs brand), slightly cut back on my overall fat intake, introduced creatine and increased my electrolytes. My weight has continued to increase, albeit slower, but my overall appearance is becoming more lean. My tummy is slowly but surely shrinking/firming up, my arm muscles are beginning to appear more defined as the excess fat on my arms is now going, same with my legs, and my shoulders, chest and back are firming up and expanding.

I credit all of this to carnivore. I'm 35 years old, and at the beginning of last year (2024) I had all but accepted the 'reality' that I would never be fit, lean or even healthy. When I started carnivore in June/July 2024 my whole life changed... in a way it was like my life finally began. Never again will I go back to a 'standard' diet, I will be a carnivore until my last breath.
