NITC ... back from the dead

Stew and sauna
I'm no meteorologist so I'm afraid I've no great insight as to whether we're in autumn proper of it this random weather will continue, but as I've blogged on before extreme temperature fluctuations can be stressful on the body and seasonal changes can lead to low mood and impaired immunity.
This is when it's important to stay flexible in what you're eating and your lifestyle. If it's warm dress lightly and eat lightly - cold dishes and raw salads will keep you cool, along with plenty of water. But don't let yourself get caught out if the temperature drops - a spare jumper or cardigan is essential at the moment, along with fairly regular checking of www.metcheck.com to plan weather appropriate outfits.
As the weather cools it's important to keep the body warm - this enhances immune function, helping you fight off colds and flu, and also keeps your body relaxed and metabolism high. Layer up, and don't be caught without a coat. Eat warm protein rich foods that will keep you warm for hours - soups and healthy stews are great for this - I get my soups from EAT and stews from POD or Leon. Porridge is a great morning warmer, but if you don't fancy it have a cold breakfast with a nice hot mug of herbal tea.
Exercise is also great for keeping your temperature up - which is why regular moderate exercise makes you less likely to get ill. Another good way to boost your temperature is to have a regular steam or sauna - if your gym has one try and go in once a week over the winter months, it's wonderfully relaxing and you can justify it as a defence against winter bugs.

To snack or not to snack
By combining slow digesting carbs, protein and fibre in every meal you're not just avoiding glazing ocer - by delaying a blood sugar low you're also delaying when you'll next feel hungry. As a result you might not find yourself reaching for a mid morning biscuit or afternoon chocolate bar.
If you get your meals properly balanced, and your pancreas is working as it should, then you should be going 4-5 hours between meals before your appetite kicks in.
So far my no snack experiment hasn't been entirely successful - I've had to snack once or twice each day, but I'm lasting longer between meals than previously and I've needed a lot less to tie me over to the next meal - just a few raw almonds.
That's not to say I'm anti-snacking - sometimes a substantial but healthy snack is just what your body needs. However if you're snacking when you're not hungry, or picking at food all day rather than eating proper meals then you need to break those habits.
Use your appetite as a guide and also be mindful that there are also occasions when you definitely should be snacking:
- under high stress. High stress disregulates your blood sugar levels so you're more likely to need something to keep you going between meals. Also stress suppresses digestion so smaller more frequent meals can be easier on the system.
- if you've got a long day. If most of us early starters ate our main meals every 5 hours dinner would be at 5pm! So a late afternoon snack is pretty much essential. It is also a good idea before a long commute home - a blood sugar low is not what you need on a packed stuffy tube.
- if you're a gym bunny or training at a serious level - eating protein and carbs after exercise is a must for recovery so have a snack if you're not about to have a meal. If you're burning off serious calories you'll also probably struggle to fit your intake into three meals and if you're trying to maximise performance/muscle gain then eating mini meals every three hours is one of the most effective strategies.

Big crash, the sequel
Your body certainly won't think you're starving on that kind of diet, however you run the risk of another kind of crash ... a blood sugar crash. We've all been there ... struggling to stay awake in a meeting following a heavy lunch!
But with a bit of care in your menu choices you can avoid the post-lunch slumber and have a productive afternoon.
One of the main culprits for the post-lunch snooze is too many carbs, especially wheat. Skip the pasta, pizza, bread and go for new or sweet potatoes or rice. Also make sure you exercise some portion control - even a big plate of brown rice will send you to sleep. Limit yourself to the volume of a tea cup. If you're going to have pudding skip the carbs altogether with your starter and main, you'll get more than enough in any dessert.
Next make sure you have some protein - fish is a good choice when eating out, but meat, eggs or pulses will do. As a rough guide have a portion the size of your fist. This will slow down the digestion of the carbs in your meal avoiding a post-meal blood sugar crash.
Finally make sure you have some veggies - not just to help you see in the dark - but the fibre will again slow the digestion of your meal.
If it all goes wrong and you end up in a post-curry coma drink plenty of water and have a green tea - resorting to coffee or chocolate to perk you up will just line you up for another crash later on.

The big crash
But losing spare weight is usually a good thing, so why the warning?
Well crash dieting usually involves severe calorie restriction, with diets for women of usually 1300 calories or less. Whilst you might accept some tiredness, light headedness, lack of concentration and headaches as a temporary side effect of following such a diet most people probably aren't aware of the long term impact, particularly on the thyroid gland.
You see when you severely cut your calories your body thinks you're being starved and so it slows down your metabolism to help sustain you on a low calorie diet. The way it does this is by suppressing thyroid function reducing your production of thyroid hormones.
When you go back to a normal calorie intake your thyroid hormone production goes back up, but repeated dieting can overtime lead to a general suppression of the thyroid gland. This then causes weight gain, which becomes increasingly difficult to reverse, leading to people resorting to even stricter diets. This is why people often find diets that used to work for them are less effective when they try them again at a later date.
Under functioning thyroids are increasingly common with a lot of hypothyroidism undiagnosed and large numbers of individuals with borderline hypothyroidism which won't be treated with thyroxine.
Whilst it's possible to restore thyroid function with proper nutrition and lifestyle changes, it can be a fairly slow recovery - much better to skip the crash diet and not get to that point in the first place.
But I'm a realist and I know that whatever health warning I give some NITC dieters will still resort to a crash diet. In my opinion a low-carb diet is actually a much better idea than a calorie restrictive diet. True, the weight lost will be mostly water which come back on when you eat carbs again, but you don't have to restrict calorie intake and the body only detects food scarcity in the first few days whilst you move into ketosis, plus you won't be hungry. Alternatively a detox diet can be a healthy way to lose weight more rapidly whilst actually having some positive effects on health.

True thirst
I was relatively successful by combining fibre, protein and low glycemic carbohydrates in every meal, but more on that later.
I'm usually pro snacking, but I found a few advantages to not eating between meals, the main one being spending at lot less time eating, but also breaking the habit of boredom grazing - something I'm definitely guilty of.
Something that I hadn't anticipated was that I started drinking a lot more water, however this shouldn't be that surprising - food provides a fair amount of our water intake so if we eat more we'll need to drink less. It also means that sometimes hunger is infact dehydration in disguise, and so drinking enough water can reduce your appetite.
By making an effort not to snack between meals my genuine thirst became more apparent and I found myself drinking water more by desire than making myself do it because I know I should. The result - I felt hungry for my next meal later than normal and in addition I felt more clear-headed than usual - bonus!
