The carnivore diet has become an increasingly popular way of eating for health and weight loss. While the simplicity of only eating meat can seem appealing, many people struggle with determining how much to eat and how often. In this article, we’ll break down optimal protein intake, fat ratios, meal frequency, and other key factors to consider when implementing a successful carnivore diet.
Focus on Adequate Protein Intake
The most important nutritional focus on a carnivore diet should be adequate protein intake. Protein provides the amino acids your body needs to maintain muscle mass, repair tissues, produce enzymes and hormones, and carry out virtually every function.
When transitioning to a meat-only diet, it’s easy to undereat protein without realizing it. Meat is very nutrient dense and satiating. Your appetite signals of hunger and fullness can become deregulated after years of eating the standard carb-heavy diet. Tracking protein intake in the beginning can be beneficial to make sure you’re eating enough.
A general recommendation is to eat around 1 gram of protein per pound of ideal or lean body weight per day. Someone who would like to weigh 180 lbs at a healthy composition could aim for at least 180 grams of protein daily. For a 150 lb person, target 150 grams of protein as a minimum.
Consuming adequate protein ensures your body has the necessary amino acids to maintain muscle mass. Muscle is metabolically active tissue that helps keep your basal metabolic rate higher. When reducing calories and losing weight, the ideal goal is to maintain muscle while shedding body fat.
The Risks of Undereating
Eating too little protein while losing weight often backfires. Your body will start breaking down muscle tissue to get the amino acids it requires. Muscle loss will cause your basal metabolic rate to slow down.
Undereating calories in general can stall weight loss. Metabolic adaptations like reduced thyroid hormone slow your metabolism to compensate for the perceived food scarcity. Your body tries to hang on to fat stores when underfed for too long.
Prolonged undereating leads to symptoms like fatigue, irritability, food cravings, insomnia, decreased immune function, and hormonal issues. Ensuring adequate protein and calories prevents these unwanted side effects.
Some popular weight loss drugs like Ozempic work by suppressing appetite. But studies show up to 30% of the weight loss from these drugs comes from loss of muscle and bone mass due to undereating.
Leverage Fat for Energy Needs
Once protein needs are met, fat intake can vary based on activity levels and weight loss goals. Dietary fat provides essential fatty acids and is the main source of energy on a carnivore diet.
Having some body fat to burn provides a buffer for days when appetite is low. But overdoing fat and consistently eating in a large calorie surplus will slow fat burning.
A useful reference is to calculate your estimated calorie maintenance level based on your height, weight, age etc. Then aim to eat around that amount or in a modest deficit if trying to lose weight. Tracking total calories once in awhile ensures you’re not regularly under or overeating.
Increase fat if you feel low energy, are struggling to recover from workouts, or have issues like hormone imbalances or thyroid problems. Women generally need more fat than men for hormonal health. High activity levels also call for more fat calories.
Meal Frequency and Timing
On a regular basis, most people feel best eating two or three carnivore meals per day. Larger infrequent meals work for some, while others need smaller meals spread throughout the day. Experiment to find your optimal frequency and meal size.
The consistency of your meal timing and frequency matters more than specific meal numbers and sizes. Avoid excessive snacking or treats between meals. Grazing perpetuates carb cravings and unstable blood sugar.
Schedule meals at times that best fit your lifestyle for adherence. Some prefer eating earlier in the day with breakfast and lunch. Others find skipping breakfast and eating a late lunch and dinner works better. Do what allows you to consistently get in proper nutrition each day.
Occasional fasting can provide metabolic benefits. But chronic undereating plus daily 16+ hour fasting is counterproductive. Make sure your average intake sustains health before trying more aggressive fasting.
Tracking Intake When Needed
While calorie tracking isn’t usually necessary long-term on carnivore, it can provide useful feedback when troubleshooting issues.
If your weight loss stalls or you suspect undereating, track for a week to validate your protein and calorie intake. This data can reveal if you need to adjust your meal size, frequency, or macro ratios to get back on track.
Tracking also helps determine if you’re overeating and need to scale back. It’s easy to overdo calories with calorie-dense ribeyes and fatty meat cuts. Sometimes we need objective data to keep our portions in check.
Use tracking as a temporary feedback tool, not a forever habit. The ability to eat intuitively based on hunger and satiety is a major benefit of carnivore eating. But checking in with tracking from time to time can troubleshoot plateaus.
Sample Daily Macros
To give you an idea of what optimal protein, fat, and calorie intake could look like, here are some examples:
150 lb moderately active female looking to maintain weight
- 150g protein (600 calories)
- 80g fat (720 calories)
- Total: 1320 calories
This provides enough protein to maintain muscle mass and metabolic rate. Fat intake gives adequate energy to fuel her activity level and hormone function. Total calories roughly match her maintenance needs.
200 lb very active male looking to lose weight
- 200g protein (800 calories)
- 100g fat (900 calories)
- Total: 1700 calories
Higher protein intake preserves his greater muscle mass. More fat fuels his intense workouts. The calorie intake promotes weight loss without deprivation at his size and activity level.
125 lb female with thyroid issues looking to improve health
- 125g protein (500 calories)
- 100g fat (900 calories)
- Total: 1400 calories
Higher fat intake provides calories and nutrients to help optimize her hormone function. Protein prevents muscle loss. More calories improve energy, immunity and thyroid function that declined due to chronic underfeeding.
These examples illustrate how macros and calories should be tailored to the individual based on health goals, body size, activity level, and lifestyle.
Avoiding Dogma and Perfectionism
When researching the carnivore diet, you’ll encounter rigid opinions on how you should eat. Some claim you need to eat extremely high protein and low fat. Others preach the need for high fat intake and protein restrictions. Certain leaders push one “optimal” meal frequency and timing for everyone.
In reality, each person has unique needs that change over time. You may require higher protein and lower fat than someone more sedentary. A mother of three kids needs a different meal frequency than a college student. There is no universally perfect macronutrient ratio, meal size and timing that applies to everyone.
The most successful carnivore eaters are those that stay consistent with their intake while making the diet work sustainably within their individual lifestyle. Don’t get caught up in dogmatic rules. Find the protein, fat and meal frequency ranges that optimize your energy, health goals and adherence. Consistency over the long-term matters more than any short-term hacks or biohacking techniques.
Meal Frequency Should Complement Your Lifestyle
- Focus on adequate protein intake to maintain muscle and prevent metabolic slowdown. Undereating protein can sabotage weight loss.
- Fat intake can vary to meet energy needs and weight goals. Increase if you feel fatigued or have hormonal imbalances.
- Meal frequency should complement your lifestyle for consistency. 2-3 meals daily works for most people.
- Occasional tracking provides objective feedback on protein/calorie intake needed to troubleshoot plateaus.
- Find a personalized approach based on your body, activity, and lifestyle. Consistency over perfection is key for sustainable success.
