Back in January I shared a post about how eating more lower calorie density foods can help you to lose weight. In many cases this can be a very useful strategy as consuming more low calorie high volume plant-based foods can be an easy way to reduce your calorie intake and lose weight without feeling deprived. However, as always, health advice is very individual and what works for one person’s goals will not necessarily work for another. Today I want to share my perspective on when a low calorie density diet is not appropriate and may actually be the cause of unexplained health problems. If you have been following a low calorie density diet and are not feeling your best then keep reading!
Something I have learned over the last 5 years is just how important metabolic rate is for our overall health and sense of wellbeing. Think of your metabolism as being the furnace that keeps you going and fuels all of your bodies functions. If that furnace is burning low you are going to feel that through low energy and fatigue and may experience other signs of a low metabolic rate such as low body temperature, constipation, insomnia, dry skin and hair and hormonal issues. On the other hand, when the furnace is running hot you are more likely to have good energy levels and digestion, sleep soundly and have well functioning hormones and healthy skin, hair and nails.
Metabolic rate is also important in maintaining a healthy body weight as a low metabolic rate means we are using energy more efficiently and are more likely to store calories as body fat than “waste” them on other bodily functions and generating excess heat. We are often told that if we are overweight we need to eat less and exercise more and in some cases this is true, as the society we live in pushes us towards more sedentary lives and over eating on processed foods. Although sometimes the problem is not a lack of exercise or eating too many calories but an issue of low metabolic rate. If you are exercising a few times a week and eating 1200, 1400 or even 1600 calories a day and still not losing weight then potentially it’s not forcing yourself to eat less and move more you need to focus on but rather healing and supporting your metabolism.
The problem with a low calorie density diet is that you can be unintentionally (or intentionally) providing your body with less calories than it needs over a long period of time and triggering your body to reduce your metabolic rate. This is the same thing as entering “starvation mode” which is not an urban myth but actually a very real phenomenon. Eating a diet made up of predominently water and fibre rich fruits, vegetables, legumes and starches may seem like a healthy way to eat but if you are not consuming enough energy to support a healthy metabolic rate you are unlikely to feel well. Because of the high volume of these foods, it is very easy to under eat whilst truly honouring your hunger and fullness signals and feeling like you are eating a lot of food. Trust me I have been there! And the worst thing is, I didn’t realise that it was my healthy diet making me feel that way.
Left… stuck in a low metabolic state, confused and exhausted
Right… on the road to recovery, feeling more energised and happy
There is nothing wrong with eating these kinds of foods, but also adding in high calorie density, metabolism supporting foods to your diet and eating enough calories can go a long way in resolving systemic health issues. I have been following the work of researchers such as Broda Barnes and Ray Peat who really focused in on the symptoms of a slow metabolism and how rehabilitative nutrition can help to restore metabolic health and create robust, healthy individuals. For a long time I thought that eating the healthiest diet possible and avoiding certain unhealthy foods was the way to restore balance and create a healing environment in the body, but over the years I have come to realise that if there is not enough energy available, the body simply cannot heal.
A couple of quick ways you can check your metabolic rate at home:
- Check your armpit temperature first thing in the morning. Do this every day for a week (preferably the week after your period for women) and if it is consistently below 36.6°C (97.8°F) you may be experiencing a lower metabolic state
- Check your resting pulse rate. If it is consistently below 70BPM, it’s a sign your metabolism may not be functioning optimally. Even though we are told that a low pulse rate is healthy and a sign of fitness, this is not always the case.
If both of the above tests show a lowered metabolic rate and especially if you are experiencing any of the symptoms of a low metabolic rate described above, then a low calorie density diet is unlikely to be appropriate and maybe it’s time to reconsider and try something new. If you are following this approach, loving it and feeling energetic and healthy then keep doing what your doing. Don’t be afraid to experiment and find what works for you and remember, be healthy to live, don’t live to be healthy!
