I posted some time ago about my great success in applying science to losing weight. At one point I had lost about 30 pounds in 6 months. Most people who lose weight go on to regain it, sometimes even eventually weighing more than they had when they started, so after six months I thought it was time to revisit my diet – or more precisely, my lifestyle.
The news is mixed. I have regained a bit of weight, but I am now fitter than ever before, as measured by endurance capability, maximum weight I can lift, resting pulse, and blood pressure. Most of the weight I have put back on (about 12 pounds) is muscle, not fat. My visceral fat is down to 11%, and my body fat 17%. I still feel flabby around the middle though, and would like to lose more weight there. Some of the weight gain – a few pounds – is fat, so it is a work in progress with many gains and a few losses.
So I think overall the verdict is that a version of this “diet” works, at least for me.
As with most things, life gets in the way sometimes. It’s difficult to stick to a particular lifestyle when there are events such as Christmas come along, or when you’re travelling. I try, but relax things a bit. After all one of my greatest pleasures is eating out, and one has to have some fun. I nearly always pass on the dessert though.
I have also had time to consider what were the essential aspects of my original diet. I still think for me then the big thing was obsessively weighing and measuring food, and calculating the nutritional content of what I ate. This monitoring enabled to stick to a diet of around 2000 Calories a day, with about 75 g protein, 25 g fibre, and 50 g or less of carbohydrate (and often less than 1 g of salt a day). (I didn’t and still don’t care about the fat/oil content because I am convinced by the data showing that fat does good rather than harm.) Note again that this intake is the inverse of the traditional food “pyramid” with a large carb intake at the base. I also aimed for as wide a variety of micronutrients as possible, by supplementation and by eating as many different vegetables, and some fruit, as possible.
I stick by these things although I have relaxed the carb limit a bit. In particular I enjoy baking, and make my own gluten-free bread, which is largely seed rather than grain-based, containing walnut pieces, linseed, flaxseed, sunflower seeds, chia seeds, and pumpkin seeds. It tastes good (others say that too), but doesn’t keep well. I still try and avoid sucrose (sugar) like the plague.
I think the increased carb intake, especially bread, makes it more difficult to lose more weight. My main struggle however has been finding a way of eating that enables me to continue gaining muscle while losing fat. I don’t yet have an answer. When you work out six times a week for 45-60 minutes a day you’re going to need more calories, but what is the ideal proportion of fat, carbohydrate, and protein? How many times should you eat a day, and when, relative to the workout? I have scoured websites and books on exercise physiology without finding any answers that convince me. It is also difficult to work out how many calories you need when you have a complex exercise regime with many different types of exercise. I’m pretty certain the answer is more than 2000 though!
I recently saw a television programme that monitored someone trying to lose weight rapidly by calorie restriction over a week. At the end he had lost weight – but it was all fluid and muscle, and muscle is the last thing I want to use. On the other hand this was a television programme not a scientific study (although the measurements appeared to be taken under laboratory conditions), his diet was extreme, and he was very fit and lean in the first place.
I am sure that the principles of my diet work if you want to lose weight and become healthier. Restrict your carbohydrate intake, watch the total calorie intake, drink plenty of water, and exercise – the more and the more different sorts the better. But to become super-fit and super-lean is a further challenge. If you know anything about the science of doing so, please let me know.
The other issue outstanding is why so many people who start to diet do well at first and then go downhill. There are of course several possible reasons.
- You don’t really like the food in your diet. I am lucky in that I don’t like the taste of sugar that much and love blueberries and fish. It would be much more difficult if it were the other way round. So you have to include as much good food that you like and also re-educate your palate.
- You’re not really too bothered about your current weight and appearance. That’s fine, it’s your life – just remember if you’re obese it might be quite a short life.
- Not giving yourself enough rewards. Rewards work! If you find the going tough, decide on a reward programme. You’re doing something important so the rewards should be reasonable: stay on the diet for a week and you deserve that new book you thought was a bit of a luxury. I’m not a great fan of “treats” in the diet as rewards: after all a diet with two days of cake treats is really just dieting for five days. Similarly all these points-based systems are over-complicated for many people (like me) and it’s easier just avoid the cake than working out if you can have it, and buy a trip to California instead.
- Lack of support. It’s difficult if everyone around you is gorging all the time. It’s difficult if you’re trying to diet alone. One of the reasons diet clubs work better than other things isn’t because of the system, but because they provide social support to encourage you.
- Yo-yo dieting. Going on a diet and then stopping and starting again, perhaps with a new system, and your weight oscillating as you diet – and don’t. You have to ask yourself why do you stop after a while. Perhaps you don’t like the food. Perhaps there is no support around. Perhaps you haven’t rewarded yourself sufficiently.
- Thinking of it as a diet rather than a lifestyle. I know I’ve used the word diet, but that’s just a shorthand. You should realise that you’re not just eating fewer cases, but embracing a new, better way of living. You’re not going just going to lose a few pounds, but you’re going to become a healthier, happier person, with a longer life expectancy and better quality of life. And a healthy body is important for a healthy mind.
Now pass the blueberries.
