The problem with dieting

ObesityLast week, I read with horror the latest obesity figures.

In the UK, 64% of adults are classed as being overweight or obese, and in the US that figure stands at an eye watering 70%.

With the average American making 4 weight loss attempts per year, and its diet industry valued at over $60billion, clearly something isn’t working.

So where does it go wrong and why don’t diets work?

The obvious starting points are:

  • We live much more sedentary lives than we ever have done before
  • We have easy immediate access to cheap high calorie foods
  • We have added food groups that we are not designed to eat.  Eg. Grains, and dairy
  • We are addicted to sugar

The result of all of the above is an epidemic in Type II diabetes, cancers, and heart disease.

Interestingly statistically the best indicator of future weight gain is if you have tried to diet.

So what is so wrong with the diets that we are encouraged to follow?

Well first of all, for a short period of time, most diets do work. The problem is sticking with them, especially when you are then battling against your body, which starts to panic because it thinks it is starving, and produces lots of hormones (such as Cortisol, Leptin and Ghrelin) to try and make you quit.

The other issue is that over time calorie restrictive diets burn muscle which in turn lowers your metabolism, so the weight loss slows down until it eventually grinds to a halt, at which point you give up, eat normally and pile the pounds back on again. Before going on to chose a different diet to fail at.

Finally, I think that diets involve far too much effort. Either its weighing food, counting calories or making complicated fussy meals, which over time become boring and onerous, and the diet breaks.

So the perfect diets must be:

  • Healthy
  • Simple to follow
  • Not counting of calories
  • No fussy meals or lots of preparation
  • Sustainable in the long term
  • Be effective at burning fat
  • Not burn muscle mass lowering metabolism

And the answer, of course is…Intermittent fasting.

Not the low calorie day’s version such as 5:2, but as close to no calories as possible (lets say 50 max).

To gain the most benefit, each fast should be 24 hours long (1 to 3 times a week) and you should eat every day (ideally dinner).

On non-fasting days you should eat a healthy balanced diet (though cutting some starchy carbs, diary and alcohol will make you feel a whole heap better), and you should eat as much as your body tells you to.

By fasting as well as weight loss you also gain huge health benefits including:

  • Reduced blood sugar and Increased insulin sensitivity (diabetes)
  • Reduced blood pressure and LDL (bad) Cholesterol. (Heart disease)
  • Reduced growth hormone IGF-1 (cancers)
  • Increased brain derived neurotropic factor (BDNF) – Mental illness and decline
  • Improved mood and self esteem
  • Causes autophagy (repair genes activated and increased longevity)
  • Reduced system inflammation (Diseases and asthma)

And the best thing is it is much easier to do than you would imagine.

So if you haven’t tried it, give it a go and enjoy the results.

 

Important note: Before you fast make sure you are healthy enough to do so. Please check with your doctor first and anyone with a history of eating disorders, low blood pressure or any other medical condition should avoid it. The advice on diabetes is mixed so suggest it is best avoided unless under medical supervision.

5:2 Diet review

The fast dietBackground

The 5:2 fast diet was popularized by TV presenter and medical journalist Dr Michael Mosley for its health benefits and weight loss.

The Fast Diet by Dr Michael Mosley and Mimi Spencer 

Diet summary

Based around Intermittent fasting, it recommends you eat well for 5 days a week, and then reduce calories to 500 (for women) or 600 (for men) on 2 non-consecutive days.

The good bits

  • As you would expect from a book written by a Doctor, the science and background to the benefits of fasting are well researched, well communicated and generally excellent.
  • There are lots of good tips for making the program work, along with personal examples making it feel more human
  • Includes recipes and ideas of meals for the fasting days
  • Author’s experiences add to its accessibility, making you feel that if they can do it so could you.

Not so good bits

  • My main issue is that it isn’t real fasting if you are eating 500 calories, and as a result you are missing out on some of the fat burning effects by not being fully fasted.
  • No real program and relies on its flexibility but suspect some would have preferred a more clearly laid out structure and plan.
  • You are still having to faff with counting calories (which can cause confusion especially on the non fasting days – clear when you read Facebook group comments)
  • Whilst it talks about eating a low GI diet, it could have focused more on the healthy eating.

Conclusion:

  • A well written and great introduction to intermittent fasting, but should have gone just a little bit further, and taken its own science to the proper logical conclusion, rather than diluting it.
  • Would highly recommend it for first timers, but think with a few minor tweaks it could have been a classic

7 tips to successful fasting

Fasting empty plateFasting has been around for as long as man has walked the earth, and is in my opinion, the most effective, healthiest, quickest and easiest way to help you lose weight. People are often surprised at how much easier it is to eat nothing than to eat small meals that leave you hungry and then battling hormones and blood sugar.

However in modern society, as with many things, anything easy is rarely worthwhile. So this is my guide to how to make your fasting day as painless as possible.

1.    When to fast

Choosing the right days to fast is vital, ideally you want to pick days when you are busy and have the most control over your environment with the least temptations. So weekends are often best avoided, as are days when you have an important work lunch or a party. Days out are also bad, as you will often be surrounded by temptations (ice cream, my own personal vice, at the cinema is a good example)

The time of day you do your fast is a personal choice. For me, start after your dinner in the evening (ideally an early one), sleep, skip breakfast, skip lunch, eat dinner 24 hours later. Job done.

2.    How long to fast

24 hours seems to be the optimum time, balancing the effect of the fast and the ease in which to complete it.

The great thing about 24 hour fasting, is that by timing it right, you still get to eat everyday.

3.    How often to fast

Anywhere from 1 to 3 days per week. But avoid consecutive days. If you are just starting and are highly motivated, 3 days is great (so Monday, Wednesday and Friday), but not for more than 28 days, and no more than twice a year as you don’t want to burn out.

January is always a good month after the excess of the holiday season, as is the month before that beach holiday or wedding.

Otherwise stick to 1 or 2 days per week depending on how you feel

4.    Surviving the fast

If you have chosen the right day etc you will already be most of the way there. On the day, you need to drink a lot of water (even better add a dash of lemon). For me, a large glass of water and a black coffee when I wake up seems to persuade my body that it isn’t hungry.

Black tea and Coffee are both extremely effective at putting off any hunger pangs.

Distract yourself. Training at the gym seems to cure most hunger pangs.

Once you have done a fast you will know for next time, when your body starts to complain, so plan ahead and do something before it hits.

5.    Hitting a wall

Sometimes 20-ish hours in, you will hit a wall and feel that you can’t go any further. If this happens, make yourself a protein shake. It will fill you up and get you through to the end. Whilst it’s not a strict fast at this point (depending on who you listen to anyway, as the warrior diet and 5:2 both seem to allow limited eating during a fast) it is better than finishing your fast early.

6.    After the fast

Eat normally and properly (ideally Paleo/low carb), don’t binge but eat until you are full.

7.    Expectations

Depending on a huge number of factors, including age, sex, bodyweight, physical activity etc etc. You should expect to lose between 0.5 – 1.5lbs per week for every days fasting. So for a month of 3 days per week fasting, that’s around 12lbs.  You can add another 50% to that figure if combined with eating well (see above) and perhaps another 25% with a good exercise plan (Strength training is most important for good body composition i.e. burning fat not muscle and maintaining your metabolism so that you don’t put the weight back on the moment you stop)

Finally, good luck and enjoy the journey.

Important note: Before you fast make sure you are healthy enough to do so. Please check with your doctor first and anyone with a history of eating disorders, low blood pressure or any other medical condition should avoid it. The advice on diabetes is mixed so suggest it is best avoided unless under medical supervision.

Paleo: A few simple rules

In this post I will talk about how to easily implement a Paleo diet with just a few simpletweaks to how you are already eating.

Firstly, Paleo should not be restrictive in terms of quantities and calories. Your body is very smart so listen to it and eat what it tells you you need.

Secondly, following a very strict Paleo diet, which admirable and worth striving for, in modern society can be difficult at times. Therefore I suggest you aim to move as close to Paleo as possible but without the faff.

The easiest way to approach it is to take each meal in turn:

Breakfast:

Scrambed eggs and fruit

  • Eat eggs and fruit.
  • Or Yoghurt with nuts and seed.
  • Plus large glass of water and black tea or coffee

Eggs can be scrambled (my personal favourite – 3 eggs, a bit of water (or a dab of milk), whisk them up and 3 minutes in the microwave – job done!), poached, hard-boiled etc.

No cereal or toast.

Lunch

  • Large green salad with lean meat or fish
  • Or hearty soup/stew (sorry no bread)
  • Large glass of water

Dinner

  • Eat as normal, but lose any heavy carbs such as potatoes, pasta, rice or bread, and go heavy on the meat and vegetables.
  • Desert – fruit.
  • Large glass of water

Snacks

  • Handful of Nuts and some fruit (apples are great)
  • Large glass of water (often our bodies mistake thirst as hunger)

If you find that you get hungry at a certain time, or snack consistently, take your good snacks with you and eat them before the time that the hunger attacks.

Drink

  • Lost of water, black coffee or black tea.

Things to avoid:

  • Alcohol
  • Diary
  • Sugar
  • Cereals, grains, starchy carbs
  • Added salt
  • Processed food

Simple.

Finally, I will mention that I don’t intend to take all the fun out of eating, though you will find that your taste buds adapt and you enjoy eating healthily more and more, especially after you break your sugar addiction, but we will also add in a cheat day. More on that later.

The Paleo diet. Part 1: Introduction and health benefits

The Paleo diet, is more a way of eating rather than a restrictive diet, and is an excellent way to eat for health and weight loss.

Background

Humans have been evolving for the last 2.3 million years, however our diets (and lifestyles) have significantly changed in the last 10,000 years with the advent of the agricultural revolution. However as a species we have failed to keep pace with these changes and as a result modern society suffers many ills from this change in diets.

Evolution

We are evolved to be hunter-gatherers, living off a diet of meat, fish, eggs, fruit, nuts and greens that we would have hunted and foraged in the wild, moving with the seasons and food availability. However today, most western nations populations live off cheap calories in the form of carbohydrates from grains, sugar and diary.  Driven by the marketing machine of the food industry. None of which we would have had access to before the agricultural revolution.

By eating more like we have evolved to, scientists have shown significant reductions in incidence of many modern diseases and conditions. We also tend to lose weight (fat) as we shift to a more protein-based diet that results in feeling fuller for longer and an increased metabolism.

Despite many people’s preconceptions, hunter-gatherers lived long healthy lives (though their average life expectancy was lower as a result of a high infant mortality) and by following a Paleo diet,

when not fasting is an excellent way to solidify and increase weight loss, longevity and also improve health at the same time.

Foods to eat (ideally organic and wild/free range)

  • Lean MeatsPaleo diet
  • Fish and Shellfish
  • Eggs
  • Nuts
  • Fruit
  • Vegetables
  • Greens
  • Oils (Olive, flaxseed)

Foods to avoid (especially farmed)

  • Any processed food and meat
  • Bread
  • Starchy carbohydrates (pasta, rice, potatoes)
  • Alcohol
  • Cereals
  • Dairy (Milk, cheese, cream etc.)
  • Sugar
  • Added Salt

The Paleo diet differs from diets such as Atkins, as it does have carbs in it, but they are coming from healthy non-starchy fruit, greens and vegetables.

A typical split of macronutrients

                                   Protein           Carbohydrates          Fat

Paleo diet                   19-35%          22-40%                      28-47%

US Diet                       15.5%             49%                            34%

Low carb diet             18-23%          4-26%                         51-78%

(E.g. Atkins)

By adding in high fiber fruit, greens and vegetables we are also providing our bodies with essential Vitamins, Minerals and Phytochemicals, which result in many health benefits.

This combined with the good fats: Monosaturated Fats (from Nuts, Olive Oil, avocados etc.) and Omega 3 (Fish) combine to provide many health benefits included:

Health Benefits of a Paleo diet

  • Reduced risk of Heart disease
  • Lower blood pressure
  • Reduced risk of cancer
  • Lower Cholesterol
  • Weight loss, increased metabolism and lower appetite
  • Reduced system inflammation
  • Increased Insulin sensitivity
  • Less disease
  • Reeducation in Asthma
  • Less digestive complaints and disease e.g. constipation, indigestion, gall stones etc.
  • Less Arthritis
  • Reduced incidence of Psychological disorders.

To name just a few.

In Conclusion, eating as we have evolved to, following Paleo guidelines is an excellent way to improve overall health and lose weight.
