Best Diets of 2020
Keto Diet
What it looks like:
Eggs and bacon for breakfast. Chicken and salad for lunch, and steamed fish with mixed veggies for dinner.
How it works:
It’s super-low carbs, with high fat, placing the body into ketosis. This is where the body is forced into breaking down fat for fuel. There is certainly merit in keeping a diet low in carbs. Because this reduces the release of the fat-storing hormone insulin. Following a Keto diet for a prolonged period can lead to acidosis or at the very least mood swings, constipation and energy lows.
However, it’s certainly very effective for weight loss and you can choose the rate at which you want to lose weight by closely monitoring the total number of kilojoules you’re eating on a daily basis.
For example, if you want to lose a kilo per week, an average-sized woman would need to eat around 6 276 kilojoules daily. Around 65% of those kilojoules would come from fat.
Pros and cons:
Weight loss can be achieved quickly, and with around 30% of kilojoules coming from protein, the body won’t lose muscle mass, which frequently happens on weight loss plans. However, you’re likely to have quite a few nutrient deficiencies, especially calcium as the diet contains no dairy or other calcium-rich foods such as soya milk.
Verdict:
Probably not a diet for the long-term but can be effective for weight loss in the short term, with the potential of reducing general obesity.

Paleo Diet
What it looks like:
Spinach, mushroom and tomato omelette to start the day. Wild salmon salad for lunch and organic roasted chicken with mashed sweet potatoes, broccoli and peas for dinner. It’s not going to be cheap…
How it works:
It’s basically a throw-back to caveman times! So, it’s based on meat, fish, vegetables, fruit, nuts and seeds. However, out go dairy, sugar, grains, legumes and beans.
The good news is that since it’s based on healthy eating principles, with foods that are not processed or pumped full of hormones, it’s certainly not in ‘fad’ territory.
Pros and cons:
Your diet will be very ‘clean’ with no refined foods allowed. It naturally follows that you’ll be getting a great range of nutrients. However, the Paleo Diet could lead to deficiencies in the mineral iodine, since dairy is one of the main sources. Iodine is key for growth and brain development during pregnancy.
Verdict:
It’s not a fad but it carries a high price tag.

Vegan Diet
What it looks like:
Homemade beans on wholegrain toast for breakfast. Chunky vegetable soup with barley and tofu for lunch and vegetarian goulash with whole grain brown rice for dinner. You won’t go hungry on this one!
How it works:
The vegan diet contains no foods from animal sources at all, therefore it will naturally contain lots of nutrient-rich fresh fruits and vegetables, whole grains, beans and legumes. Another positive of the diet is that since our food chain is far from perfect with tonnes of animal products being pumped full of chemicals and antibiotics, you’ll be escaping their onslaught!
Pros and cons:
The vegan diet is generally nutrient-dense with lots of minerals like magnesium, potassium and calcium. However, vegans can sometimes miss out on vital vitamins, especially vitamin B12.
Interestingly, tempeh is taking over from tofu in terms of popularity as a vegan protein source. Tempeh contains probiotics, which naturally encourage the body’s production of vitamin B12, so this could help to plug some of the gaps. However, taking a daily multivitamin is recommended.
Verdict:
Veganism is certainly increasing in popularity. But many people have had to revert to eating some animal protein due to health issues associated with low protein intake.

Zone Diet
What it looks like:
Egg white omelette with spinach and mushrooms for breakfast. Chicken salad with avocado for lunch and roasted hake with veggies for dinner.
How it works:
It’s based on being ‘In the Zone’ where your body better manages the insulin response and has more control of inflammatory issues. The diet requires a balance of 1/3 protein and 2/3 carbohydrates with just a small amount of monounsaturated fats from avocado, olive oil and nut butter.
Pros and cons:
The great news about this diet is that it includes plenty of colourful foods every day and is much more likely to give the body the nutrients it needs; richly coloured fruits and vegetables are loaded with vitamins and minerals, plus antioxidants although starchy veg and highly sugary fruits such as bananas should be avoided.
However, it’s lacking in essential polyunsaturated omega-3 fats found in oily fish, nut and seeds. These fats are needed for hormone balance, glowing skin, healthy eyes, heart and brain. However, any diet that reduces inflammation can certainly promote longevity.
Verdict:
Most criticism of this diet has been about its sustainability and the difficulties in maintaining it with a busy lifestyle.

Intermittent Fasting
What it looks like:
Eggs, smoked salmon and avocado for the first meal. Chicken, broccoli and quinoa for dinner.
How it works:
The usual routine is to skip breakfast and eat one meal around 1pm and another around 8 pm. The body is then fasting for 16 hours. This diet will produce weight loss because the body burns fat when it’s in the post-absorptive phase of digestion.
This means it’s not been fed for a while and insulin levels are low, allowing fat burning to happen. Problems can arise because there are only two windows of opportunity for eating well-balanced, nutrient-rich foods with a good proportion of macronutrients.
Pros and cons:
There are many health benefits to this diet, especially relating to heart disease and inflammatory issues. However, it may be low in antioxidants, which can affect the immune system, because there’s less opportunity for food intake overall.
Verdict: This needs to be strictly followed to stand any chance of the body getting what it needs.
