What You'll Learn
Nutritional benefits and risks
Meat is a significant source of nutrients and has been an important part of the human diet throughout evolution. It is a good source of protein, iron, zinc, and B vitamins, including vitamin B12. Heme iron, which is found in meat, is absorbed more efficiently by the body than non-heme iron from plants. Meat also contains bioavailable essential nutrients and high biological value protein.
However, a predominantly meat-based diet may come with certain risks. The World Health Organization (WHO) has claimed that eating processed meat causes colon cancer and red meat probably causes cancer. While the observational data supporting these claims is weak and not supported by intervention studies, there are other factors to consider. For example, those who eat a lot of meat may also be more likely to be overweight, exercise less, and consume fewer vegetables and dietary fiber, all of which can contribute to an increased risk of cancer and other health issues.
Additionally, eating too much red meat, processed meat, or meat high in saturated fats can lead to health problems. Processed meat is often high in salt, which can increase the risk of high blood pressure. Consuming large amounts of red meat has also been linked to an increased risk of diabetes and weight gain, although this may also be influenced by other dietary factors. Liver and liver products should be consumed in moderation due to their high vitamin A content, as excessive vitamin A intake can increase the risk of bone fractures.
It is worth noting that the efficiency of nutrient transfer from an animal's diet into its meat is generally low, and direct human dietary supplements may be a more efficient and cost-effective way to obtain certain nutrients. For example, the use of seaweed in animal feed has been shown to improve meat quality and nutritional value, but it may be more beneficial and cost-effective for humans to consume seaweed directly.
In conclusion, meat can be a nutritious part of a balanced diet, but overconsumption may lead to health risks. It is important to practice moderation and ensure adequate intake of other food groups to maintain a healthy and varied diet.

Weight loss and health issues
A predominantly meat-based diet, also known as the carnivore diet, is a highly restrictive diet that consists of only animal products, including meat, fish, and eggs, with small amounts of low-lactose dairy. This diet claims to aid weight loss and address various health issues. While it may offer short-term benefits, there are potential health risks associated with it, and it may not be sustainable in the long term.
Weight Loss
The carnivore diet can lead to weight loss due to its high protein and fat content. By eliminating carbohydrates, the body enters a state of ketosis, where it burns fat for energy instead of carbohydrates. This can result in increased metabolism and subsequent weight loss. Additionally, protein helps you feel fuller for longer, leading to reduced calorie intake.
Health Issues
However, a meat-based diet also presents several health issues. Firstly, it is high in saturated fats, which can increase the risk of heart disease by raising "bad cholesterol" (LDL) levels. Secondly, consuming large amounts of red meat has been linked to an increased risk of colorectal cancer, including colon and rectal cancer. The diet also lacks essential nutrients found in plant-based foods, such as fiber, vitamin C, and antioxidants, which are crucial for gut health, immune function, and disease prevention. The absence of fiber can lead to constipation and digestive issues, and the lack of key nutrients can result in electrolyte imbalances, causing muscle cramps, dizziness, and fatigue.
Additionally, the carnivore diet may not be suitable for certain populations, such as children and pregnant or lactating women, and those with a history of disordered eating. It is also difficult to follow long-term due to its restrictive nature and lack of variety. A balanced diet with a variety of healthy foods is generally more sustainable and beneficial for overall health.

Meat-based communities
Meat can be a nutritious part of a healthy diet, providing a good source of protein, vitamins, and minerals. However, a predominantly meat-based diet, such as the carnivore diet, has potential health risks and is not recommended for everyone.
The carnivore diet consists exclusively of animal products, including meat, fish, eggs, and small amounts of low-lactose dairy. Proponents of this diet claim that it aids weight loss, improves mental health, and helps manage chronic physical conditions. Additionally, some people with diabetes have found that a meat-based diet lowers their glucose levels and makes it easier to manage their low-carb lifestyle.
However, the carnivore diet is extremely restrictive and difficult to follow long-term. It does not offer much variety and eliminates entire food groups, which can lead to nutrient deficiencies and overconsumption of certain nutrients. For example, it is high in saturated fat, which can increase the risk of heart disease and stroke. It also lacks fiber, which is essential for gut health and can only be found in plant foods.
While a meat-based diet may work for some individuals, it is important to proceed with caution. It is recommended to introduce dietary changes slowly and consult a healthcare professional, especially for those with special nutrient needs, such as children, pregnant or lactating women, and those with a history of disordered eating. Additionally, a balanced diet that includes a variety of healthy foods, including plant-based options, is generally considered more sustainable and beneficial for long-term health.

Food preparation and safety
Meat can be a nutritious part of a healthy diet, but it's important to prepare and cook it safely to avoid food poisoning and other health risks. Here are some detailed guidelines for safe food preparation and storage when following a meat-based diet:
Storage
Always store raw meat separately from other foods. Keep raw meat and poultry in clean, sealed containers on the bottom shelf of the fridge so that it cannot touch or drip onto other food. Make sure to follow any storage instructions on the label and do not eat meat after its "use by" date. If you're not going to cook the meat immediately, it's best to store it in the freezer. Raw meat generally lasts safely for around three days in the refrigerator, but it can be frozen for several months if sealed in an airtight package. Keep your freezer close to 0°F (-17.8°C) to retain nutrients and keep food fresh, and maintain your refrigerator at around 34°F (1.1°C) to prolong the shelf life of foods.
Preparation
When preparing meat, always wash your hands before handling any food items. It's important to use separate utensils and cutting boards for meat and other ingredients, especially if they won't be cooked together. Keep your preparation space and utensils clean, and wash them thoroughly with warm soapy water or disinfectant after they come into contact with raw meat. Avoid washing raw meat before cooking, as this can spread bacteria through water droplets. Instead, cook meat thoroughly to ensure harmful bacteria are killed. Meat is generally considered cooked when its juices run clear and there is no pink or red meat left inside. However, some types of meat, such as poultry, burgers, and fish, need to be cooked all the way through to prevent foodborne illnesses.
Cooking
When cooking meat, it's important to avoid high-heat cooking methods that can char or overcook the meat. If grilling or barbecuing, wipe away any drippings promptly. For fish, aim for an internal temperature of 145°F (62.8°C) or until the flesh is opaque and separates easily. For clams, oysters, and mussels, ensure the shells open during cooking, and discard any that remain closed. For scallops, the flesh should be rigid and not see-through. Shrimp and lobster should be shiny and opaque. Do not leave cooked seafood out for longer than two hours; keep it refrigerated or insulated with ice if consuming later.

Long-term sustainability
A predominantly meat-based diet, also known as the carnivore diet, consists of eating only animal products. This includes red meat, poultry, seafood, eggs, and dairy. While meat can be a nutritious part of a balanced diet, there are concerns about the long-term sustainability of a meat-only approach.
Firstly, a meat-based diet is extremely restrictive and difficult to follow long-term. It eliminates entire food groups, including fruits, vegetables, grains, legumes, nuts, and seeds, which are recommended in dietary guidelines. This restriction can lead to food cravings, and it is challenging to maintain due to a lack of variety.
Secondly, a meat-based diet may result in nutrient deficiencies or overconsumption of certain nutrients. Meat is a good source of protein, vitamins, and minerals, but a balanced diet typically includes protein from both animal and plant sources, such as beans and pulses. A meat-only diet lacks the beneficial plant compounds, antioxidants, vitamins, fibre, and minerals found in plant-based foods, which have been associated with a lower risk of long-term health conditions like heart disease, certain cancers, Alzheimer's, and type 2 diabetes.
Thirdly, the sustainability of a meat-based diet is questionable due to its environmental impact. While there are valid reasons to consume meat, plant-based diets are generally considered more sustainable and eco-friendly.
Finally, certain populations with special nutrient needs may not meet their requirements on a meat-based diet. This includes children, pregnant or lactating women, and those with a history of disordered eating.
In conclusion, while a meat-based diet may offer some potential benefits, it is challenging to sustain long-term due to its restrictive nature, potential nutrient deficiencies, environmental concerns, and the specific needs of certain populations. A balanced diet that includes a variety of healthy foods from both animal and plant sources is generally recommended for optimal long-term health and sustainability.
