- Hyperthyroid is what I call it, as it allows the thyroids to normalise blood sugar levels, rather than supplying artificial boosts (e.g. from sugary foods). The idea is that when you take away the imposed energy your body gets back into the habit of regulating energy itself (Homo sapiens isn’t designed to run on ‘high octane’ glucose). After a few months of this diet you will find that energy levels are more consistent throughout the day, and there will be a better natural response to exercise, especially freediving.
- I have a personal prejudice against MSG, but I believe there is a lot of concern over its long term effects, especially on the heart.
SFA is saturated fatty acid. The general rule is if it’s solid at room temperature then its saturated (unhealthy unless you’re Atkin) whereas if its liquid then it’s probably unsaturated (e.g. olive oil, cod liver oil etc). SFAs increase cholesterol in the blood (interestingly enough cholesterol itself doesn’t increase blood cholesterol, although it has other detrimental effects, and is usually associated with SFAs).
- ù is the Greek symbol for omega.
- Chicken Breast is 100% quick twitch fibre. Most freediving training models are designed around building quick twitch muscles for anaerobic exertion. Also chicken breast (sans skin) is very low in SFAs (compared to red meats).
- Honey (especially unprocessed) and fruits contain mostly fructose, which is a disaccharide. The glucose that is in sweets and all American food is a monosaccharide. The difference is that glucose is absorbed very quickly, giving a peak of blood sugar that quickly dissipates, whereas fructose provides a more prolonged and consistent energy source.
The benefits of regulating eating and sleeping times are just as great as those of a healthy diet. If meals are at a particular time of the day then the body knows to produce digestive enzymes at those times. The same applies for sleep – the body adapts biorhythms and energy levels to the schedule.
In my experience sleep duration is not as important as consistency and quality. REM (dream) sleep is the only important stuff. An experiment was done where one group was woken every time they reached REM sleep, but slept for the same overall time as another group that weren’t interrupted. The first group showed symptoms of sleep withdrawal – they behaved as if they hadn’t had any sleep at all, while the second group was bright eyed and bushy tailed. (NB. if you can’t remember your dream that doesn’t mean that you haven’t been REMing – we only remember dreams we wake up in the middle of. So siestas – which don’t usually reach REM – aren’t that beneficial, and are usually more a sign that you overate for lunch).
Sleep consistency means keeping the same hours and duration. Sleep-ins can be just as bad as late nights.
Your brain is more active during sleep than when you are awake (and it needs to be). However it is disrupted by a heavy meal in the gut, so try and stop eating at least 3 hours before bedtime.
I will try and get hold of the chocolate cake recipe off my mother. It doesn’t taste of beetroot at all (if you give some to friends they will never guess the secret ingredient).
