Over 50 and struggling with frustrating roadblocks to weight loss?

Are you finding as you get a little older that you are doing all the things that have always worked for you in the past but you can’t lost weight? In fact it even seems to be creeping on around the middle?

There are a few obstacles that can affect you as you get older that make it harder to lose weight. One of the biggest roadblocks is nutrient deficiency and there are three areas that are critical;

  1. Key minerals for metabolism like chromium and iodine.
  2. Protein in adequate quantities.
  3. Kilojoules at an appropriate level.

Chromium is a key mineral for blood sugar balance and low levels are often associated with cravings for sugar and carbohydrates (to give you the quick sugar fix). While its found in a range of foods, such as meat, grains, green beans and fruits, levels can be impacted by a diet high in refined foods and simple sugars.

Iodine is an important nutrient for glands and in particular the thyroid gland, which controls growth and metabolism. There aren’t a wide range of food options with iodine, which may explain why deficiency is fairly common. Good food sources include seafood, seaweed, organic eggs and celtic sea salt. Some products such as salt can be fortified with iodine.

A deficiency of iodine is harder to detect as quite often symptoms are sub-clinical, however one of the most common symptoms is weight gain. In more significant deficiency you see signs of fatigue, hair loss and chilliness. Another symptom that often appears for women is fibrocystic or “lumpy” breasts.

A combination of chromium and iodine deficiency results in a significant block for metabolism and makes it very difficult to lose weight.

Inadequate amounts of protein in the diet can also make it hard to lose weight. Many women often find they tend to crave carbohydrates as they provide quick and easy energy. Protein has the same kilijoules per gram but also provides balanced blood sugar for a longer period. Including an adequate amount of protein at each meal keeps your blood sugar balanced and reduces cravings. What is an adequate amount of protein? Generally for weight maintence you are looking at 0.8g per kilo and for weight loss between 1-1.2g per kilo.

Translated that means for a women who is 80kg she needs to be eating 64g of protein a day to maintain weight and between 80-96g to lose weight. You also need to be aware that typically the protein content of animal meats is usually about 20-25% whereas for vegetarian proteins its typically 10-15%. A typical day could include 2 eggs (12g of protein), a small can of tuna (24g) and a chicken breast fillet (50g).

Under eating is also a significant problem for many people. Years of yoyo dieting and keeping kilijoules low can reduce your metabolism and make it difficult to lose weight. An historical study in Minnesota with prisoners looked at the impacts of prolonged starvation with calories reduced so that participants lost 25% of body weight. The study showed a reduction in the bodies metabolism, as well as an increase in depression and emotional distress.

Eating inadequate kilijoules can cause your metabolism to slow down, meaning you won’t burn as much fat off when you engage in physical activity. Your body requires energy when you walk, work out, think, breathe, just about everything!When you deprive your body of the fuel it needs to burn calories, it will begin to store food and enter a sort of “survival mode.” So even when you exercise, your body will protect the fat that it has stored, and you may not be able to lose the weight you want to lose. 

To recover from long periods of yoyo dieting you may need to work on increasing your metabolism as a priority. Gently increasing exercise plus using hormetic stressors is a useful way to approach the problem. Heat and cold, stressors which boost energy and slow ageing has a good summary of some approaches which may be helpful.

Five minerals you need to know about !

In my clinic last year there was a lot of focus on Calcium and osteoporosis but realistically everyone knows they need Calcium for bone health. There are however 20 essential minerals for health and in this blog you are going to find out about five that could be having a big impact on your current health and wellbeing. In case you do want more information on Bone Health read my latest blog on Building Healthy Bones.

Iodine is basically found in things that come out of the ocean, like fish and seaweed, but also in organic eggs and celtic sea salt. Iodine is an essential nutrient for glandular health and in particular the thyroid gland. Thyroid hormones require iodine to form T4 or thyroxine which then has an iodine ion removed to become the active hormone T3, or tri-iodothyonine.

The thyroid is responsible for growth and repair, so effectively controls your metabolism but also your ability to heal effectively. When your thyroid health is impaired you tend to have one of two reactions, first up if your production of thyroid hormones is too low you tend to become fatigued, foggy, constipated and suffer from dry skin and hair loss. If you are overproducing thyroid hormones you tend to be agitated, lose weight easily and have loose bowels. You do need to be careful supplementing with iodine particularly if you suffer from auto-immune conditions and its preferable to build supplements up slowly as well as having iodine from food sources.

Selenium is also a key nutrient for thyroid health and is important for the production of anti-oxidants such as glutathione. Australian soils tend to be low in selenium and to get an adequate dose four brazil nuts a day is recommended, but ideally they actually come from Brazil where the soils are still replete in selenium.

Glutathione is an anti-oxidant which can prevent damage to cells, it also regulates DNA production. It can be taken as a supplement however supporting your own body to produce adequate glutathione is probably recommended as a longer term strategy.

It is usually fairly easy to determine whether Chromium is a deficiency for someone as they will crave sweet foods and may be prone to dizziness or fatigue if they haven’t eaten in a few hours. Chromium is a key component of glucose tolerance factor. If you eat a meal high in carbohydrates and then feel tired a couple of hours later it is possible that you cannot manage the surge in glucose in your blood from the food. Glucose tolerance factor binds to insulin and enhances its reaction often by a factor of three, so low levels of chromium will reduce your ability to manage foods high in glucose.

People who are deficient in both Chromium and Iodine will have a lot of difficulty in losing weight as they are two key minerals for your metabolism.

Potassium is another key nutrient as it is an important electrolyte in the body and it is a useful marker of adrenal health. Ideally potassium and sodium need to be in a reasonable balance as an indicator of good adrenal health. Potassium is the major electrolyte in the intercellular fluid and sodium is the major electrolyte in the extracellular fluid. Low potassium levels can result in cells being dehydrated and operating less effectively.

Potassium is frequently low in people who have been under chronic long term stress or those who do not eat sufficient fruit and vegetables, which are usually the best sources.

Most people cite bananas as a good source of potassium at about 400mg. There are a range of good quality sources including half an avocado (487mg) or a medium sized sweet potato (541mg) or 1 cup of navy, lima or canellini beans (840mg) which all contain a higher level of potassium than bananas.

Copper is a mineral that often gets ignored as the focus for the immune system in particular is often on zinc, however inadequate copper levels make it difficult for you to respond to bacterial infections. It is found in all  tissues and plays a role in making red blood cells and maintaining nerve cells and the immune system. The best sources include seafood, organ meats, whole grains and legumes. A popular source of copper is Chocolate, however it is the raw cacao that is high in copper.

Copper is usually more problematic when is it in excess and this can be associated with increased anxiety, headaches and allergies.

Iodine – a critical element for metabolism

Fish Oil CapsulesEarlier this year I was working with a tall guy who was close to 100kg on the scales. He could lose 5-6kg and then get stuck. Ideally he needed to be around 86-89 kilos for his height and frame. He could be eating well and exercising a lot but he struggled to loose the extra weight and he was really frustrated with it.

I did an Oligoscan test to look at nutrient minerals and see what his levels were like. Given his overall presentation I was thinking about possibly a slow thyroid and expected to see low levels of zinc, selenium or iodine which are all critical for effective thyroid function. Surprisingly his zinc and selenium levels were all in the normal range but his Iodine was critically low.

Snapshot

Why is Iodine so important? Basically thyroid function is dependent on adequate levels of iodine and tyrosine. The thyroid gland produces two primary hormones – thyroxine (also referred to as T4) and tri-iodothyronine (also referred to as T3). The numbers 3 and 4 refer to the number of atoms of iodine in the hormones. Iodine is essential for the production of thyroid hormones and we need about 150 mcg each day.

Iodine is important for the health of all glands but also critical for early growth and development during pregnancy and early childhood. Iodine deficiency in early development can contribute to a 10-15 point drop in IQ’s.

Iodine deficiency is increasingly common in Australia. Good sources of iodine include eggs, fish, seaweed and Celtic Sea Salt, but many people rarely consume fish on a regular basis and will need to rely on supplements to increase levels.

My weight loss client was asked to supplement with iodine at a reasonable level and over the next 4-5 months reduced his weight to 87kg. Generally a weight loss of 0.5-1kg a week is reasonable and sustainable.

Long term supplementation with high amounts of iodine can inhibit thyroid function so it is important to ensure when supplementing that you are carefully monitored and ensure you are receiving adequate but not excessive amounts of iodine. The cautious recommendation is no more than 600 micrograms a day when you are deficient.
