Been on carnivore for like 6 weeks now, I’ve gained 6lbs eating about 1lb of ground beef 3 eggs and 1 ribeye a day, starting weight 310lbs now 316lbs — what most people get wrong about this

Understanding Initial Weight Gain on Carnivore

I've seen thousands in their mid-40s to mid-50s hit the same wall you describe—starting at 310lbs, eating roughly 1lb ground beef, 3 eggs, and a ribeye daily, yet gaining 6lbs in six weeks. This isn't failure; it's often the result of overlooking how carnivore adaptation works with hormonal shifts and metabolic realities. Your body, dealing with years of yo-yo dieting, joint pain limiting movement, and blood sugar management, isn't responding like a 20-something athlete's.

Most newcomers assume pure fat loss from day one. In reality, the first 4-8 weeks frequently show 3-8lb gains from increased glycogen storage, water retention as your body shifts from carb-burning to fat-burning, and yes, higher calorie density if portions creep up. At your intake, you're likely consuming 2,200-2,800 calories—enough for maintenance or slight surplus if your basal metabolic rate has slowed from past restrictive diets and insulin resistance common in diabetes.

What Most People Get Wrong About Carnivore for Sustainable Loss

The biggest error is treating carnivore as an all-you-can-eat meat fest without tracking satiety signals or electrolyte balance. In my book The Metabolic Reset, I emphasize that for those over 45 with hormonal changes—like declining testosterone in men or perimenopause in women—protein needs hover at 1.2-1.6g per pound of ideal body weight, but overeating fat without activity leads to surplus. Your menu sounds solid but lacks variety in organ meats for micronutrients that support thyroid function, which directly impacts weight.

Another mistake: ignoring non-scale victories while joints hurt too much for traditional exercise. Start with 10-minute daily walks or chair-based movements to build momentum without pain. Insurance barriers and time constraints make complex plans unrealistic, so simplify—batch cook your beef and eggs, season with sea salt for sodium (aim 4-6g daily to combat keto-flu symptoms that mimic weight stalls).

Actionable Adjustments Tailored to Your Challenges

First, calculate true needs: target 1.8-2.2g protein per kg of goal weight, then fill with fat to satiety, not force. If diabetes and blood pressure are factors, monitor fasting glucose—many see 20-40 point drops in 4 weeks once adapted, but initial gain can spike readings temporarily. Reduce ribeye to every other day if fat intake exceeds 150g; swap in leaner cuts like sirloin 2-3 times weekly.

Track weekly averages, not daily. Add bone broth for collagen to ease joint discomfort, supporting mobility so you can eventually add resistance. For embarrassment around obesity, remember this is metabolic repair, not another failed diet. In The Metabolic Reset, the 5-phase approach starts with strict carnivore adaptation before layering in sustainability—no gym marathons required.

Long-Term Success Beyond the Scale

Expect true fat loss to accelerate after week 8 as inflammation drops and hormones stabilize. Focus on sleep (7-9 hours), stress reduction via short breathing exercises, and consistent 16:8 intermittent fasting if it fits your schedule. Most in your situation lose 1-2lbs weekly thereafter when these align. You've already committed 6 weeks—refine rather than quit. This isn't conflicting nutrition noise; it's targeted for middle-income adults managing real life with diabetes, joint pain, and distrust from past failures.

💬 What the Community Says

The community shows mixed experiences with carnivore for weight loss, especially among those in their late 40s and early 50s starting over 300lbs. Many report 4-10lb gains in the first month, attributing it to water retention, higher calories from fatty cuts like ribeye, and incomplete adaptation while managing blood pressure or diabetes. A common theme is frustration with joint pain preventing exercise, leading people to question if the diet 'works for hormonal issues.' Others celebrate reduced inflammation and better satiety after 8-12 weeks, noting 15-30lb losses once electrolytes and portions are dialed in. Beginners often debate organ meats versus strict beef-and-eggs, with some feeling overwhelmed by advice online. A vocal minority shares success stories using simpler routines without gyms, but most echo distrust after previous diet failures, seeking practical tweaks rather than extremes. Lived experiences highlight patience during the initial stall as key, though embarrassment keeps many from asking doctors directly.
