Nutritionist Shereen Lehman ranks 7 diet plans


With so many information about that eating skeleton and diets to follow, it’s tough to collect that is best.

Nutritionist Shereen Lehman has finished it for you. 

The co-author of Superfoods for Dummies has ranked 7 diets from a Mediterranean to a Alkaline diet.

She rated any diet on a scale of one to five, with a top scores going to those done adult of a healthy change of food groups, and though complicated restrictions.

Here we take we by a several diets, and uncover how they ranked from best to worst.


The Mediterranean diet follows eating habits of countries adjacent a Mediterranean Sea

The diet combines a eating habits of countries that limit a Mediterranean Sea – generally Spain, France, Italy and Greece. It is marketed as an eating settlement rather than a structured diet.

It encourages supporters to eat reduction red meat, sugarine and jam-packed fats and to bucket adult on produce, gaunt protein, nuts and other sustaining foods.

Dairy products such as milk, cheese and yogurt are allowed, though in moderation.

According to Lehman, this is a best of a seven. While it can be costly to maintain, it is a many offset diet.

‘The Mediterranean diet includes a lot of tasty food and has good variety. Of course, if we need to remove weight you’ll still need to count calories,’ she writes.

2. 5:2 DIET

The 5:2 diet allows eating whatever we wish for 5 days a week and fasting for a other two

A renouned weight detriment diet, a 5:2 diet consists of 5 days of ‘normal’ eating – following a standard 2,000 calorie-a-day diet.

The remaining dual days are singular calorie fasts, with 500 calories authorised for women and 600 for men.

Although fasting can exceedingly impact your appetite levels, it can also give your digestive tract a rest, Lehman says.

‘It seems to be effective for weight detriment and we like that we can eat what we wish on unchanging days,’ she wrote.


The extract clean diet consists of celebration usually uninformed squeezed juices and no plain foods

The extract clean diet consists of celebration creatively pulpy fruits and vegetables for a integrate of days to a integrate of weeks.

All plain dishes and ethanol are to be avoided.

Lehman says she likes that a diet promotes expenditure of fruits and vegetables, though records that it can be high in sugarine if too many fruit is used. 

She writes: ‘A extract clean is a good approach to burst start a diet, presumption we follow it with a healthy offset diet.’


The Paleo diet promotes eating a approach that early, Paleolithic humans would have eaten

The Paleo diet is formed generally on dishes reputed to have been accessible to early, Paleolithic humans. 

The diet encourages eating grass-produced meats, uninformed fruits and vegetables, and eggs. It discourages cereal grains, dairy and processed foods. 

While Lehman says a diet includes lots of ‘clean’ foods, it lacks several nutrients including calcium and vitamin D.

‘The Paleo diet isn’t balanced, and excludes a lot of healthy foods,’ she writes.

‘If we unequivocally wish to follow this diet, name fish for healthy fats and eat a lot of fruits and vegetables, generally dim immature shaggy vegetables for calcium.’


The Alkaline diet  is ostensible to keep a body’s pH levels offset and forestall disease

The Alkaline diet comes from a faith that certain dishes can impact a astringency and pH levels of corporeal fluids, including a blood and urine, and can therefore be used to provide or forestall diseases.

It is meant to keep a PH levels between 7.35 and 7.45 and presumably improves memory, boosts appetite levels, reduces flesh pain, and prevents headaches and bloating.

The usually authorised dishes are uninformed fruits, vegetables, nuts and legumes.

While a pros embody increasing food and unfeeling consumption, many other whole dishes are removed. Lehman did not like a singular series of dishes accessible to eat.

She writes: ‘I like that this diet is high in fruits and vegetables, though it’s out of change – it can be too low in protein, and grains are out of a question. 

‘Your physique regulates pH utterly well, so a judgment doesn’t make clarity to me.’


The Dukan diet consists of 4 phases with a final proviso being a lifelong commitment

The diet was combined by French nutritionist Pierre Dukan in a 1970s, and published in a book in 2000, as an bid to fight plumpness in France

It consists of 4 phases for weight loss. It allows 100 foods, and a fourth proviso is a life-long commitment.

1. The Attack Phase consists of pristine protein and creates a kick-start to a diet. During this phase, we can eat 68 high-protein dishes that presumably furnish evident weight loss.

2. The Cruise Phase adds 32 vegetables and will take we to your ‘true weight’. In total, we can name from 100 healthy foods. The normal length of this proviso is formed on a report of 3 days for any bruise we wish to lose.

3. The Consolidation Phase is when you’re during your many vulnerable, as a physique has a bent to fast recover weight. This proviso prevents a miscarry outcome by gradually returning formerly banned dishes in singular quantities and permitting for adult to dual ‘celebration’ dishes per week. There are 5 days per each bruise mislaid in a Cruise Phase.

4. The Stabilization Phase is a lifelong phase. There’s a leisure for healthy eating along with 3 non-negotiable rules:

  • Three tablespoons of Oat Bran per day
  • Walk 20 mins daily and name to take a stairs whenever possible
  • Have a pristine protein Thursday, i.e. Attack Phase menu.

Although a diet can lead to discerning weight loss, it can boost cholesterol levels and has too many rules, according to Lehman.

‘Too many rules, too many restrictions and it can lead to nutritive deficiencies,’ she writes. 


The Blood Type diet promotes ‘personalized’ eating habits formed on your blood type

Claiming to be a many personalized form of diet, a Blood Type diet recommends opposite dishes for opposite blood forms formed on a supposition that dishes conflict chemically to opposite blood types.

Type O: High protein, gaunt meat, fish, vegetables

Type A: Fruits and vegetables, beans, legumes, whole grains

Type B: Green vegetables, eggs, certain meats, dairy

Type AB: Tofu, seafood, dairy, immature vegetables

While all of a diets inspire a expenditure of healthy, healthy dishes with no intake of sweetened or greasy foods, there is no systematic backing.

Lehman writes: ‘The Blood Type diet is an engaging hypothesis, though there’s no justification to uncover that it works so we won’t be recommending it.’
