Losing weight can be beneficial for your overall health and well being. Having said that, being thinner does not always mean that you or another person are actually healthy on the inside.
Some people are naturally set up through their genetics to have a smaller frame and to be able to keep their weight down easily, compared with others that find it extremely hard to shift the weight.
It is important to fuel yourself with the right types of food, no matter if you are naturally slender, or naturally find it hard to lose weight (and therefore call it quits on trying to eat well for your body).
By eating nutrtitious food, and excercising, we can shift the numbers that come up on a blood test or a blood pressure monitoring screen without actually shifting kilograms on the scale.
There is a great article in the GI newsletter by APD Nicole Senior who provides a list of the essential components to a healthy diet.
She outlines the major food groups and which foods fit into these. I would make a couple additions, and say that when selecting your carbohydrate based foods, to not only look for low GI (which you certainly should aim to do), but also to include foods rich in resistant starch, to help increase insulin sensitivity and thereby reduce your liklihood of developing Type 2 Diabetes, as well as aid with weight management through satiety and increased fat burning potential.
There is also an interested article that follows in the newsletter on lentils and pulses, and how you use them in your daily meals to bump up your fibre intake.
So remember, the next time you are about to go for the extra cream biscuit because you are losing hope in your ability to lose weight, put it down, move away from the packet, and know that no matter what the numbers on the scales say, you still can make a big difference to your health by sticking with the healthier options.
