Intermittent Fasting for Losing Weight and Maintaining Muscles
A recent research at the Otago University looked at the weight loss and health benefits of the three well known diets, paleo, Mediterranean and intermittent fasting. 250 participants of this study chose one of these diets and followed them. Intermittent fasting seemed to result in the most weight loss. And Mediterranean diet was the one that improved the blood glucose of the study participants.
Those who took this path followed the intermittent diet twice a week by eating or drinking only about 1/4 of their normal calorie intake amounts on those days. There is not really a single way to lose weight or be healthy according to the researchers and that there are different options or a combination of them that may work on different people in different ways. Participants continued with the diet they chose in their real life and reported improvements in the way they felt overall and lost some weight.
When it comes to the sensitive issue of muscle loss during the intermittent fasting, you need to realize that weight loss is not enough by itself to lose fat. The real weight loss and what we all want is losing fat while maintaining the muscle mass. The more muscles you have the higher your daily calorie intake will be. And your body will look nice, toned and firm overall. Whatever diet path you choose it is important that it doesn’t make you lose your muscle mass. And this is often what we hear from people when we say we’re going on intermittent fasting.

You need to bear in mind that whatever eating plan you choose for weight loss, it will cause some muscle loss because of the lower calorie intake. There is not a single diet that doesn’t make you lose at least a little bit of your muscles and nobody keeps all their muscle mass. For example if you don’t have enough protein intake in your diet your body can use the muscle proteins when there is a need during longer intense exercise. And this is often a minor muscle protein loss that does not present any risks to your health.
For some people with little muscle mass, if they diet over a longer period of time with constant daily calorie deficit, their weight loss starts to plateau and they lose less weight. And what they get as a result is something like skinny fat or slim and soft syndrome. What these people can do is start working on building muscles to look and feel better. With the fasting method, as long as you don’t fast more than three days (72 hours) your body will keep its muscle mass and use the glucose and fat deposits for energy. And this means your muscle mass is protected.
What we all want in a diet or weight loss program is to increase the fat loss while losing as little muscle as possible. If you fast more than 3 days your body will start using the muscle proteins as a source of energy. Please do not overdo the cardiovascular activities like jogging or running as they can lead to muscle loss over time. Try and walk or choose other slow activities over time and on an empty stomach, so that your body uses the fat as a source of energy. You can lift weights, run or swim, but by having days off (intervals) to stimulate your muscles.
You need at least the recommended daily amount of protein, which is 0.8 g per kg of body weight to keep your muscle mass. And it is obviously better if you consume more, but remember everything needs to be in moderation. Intermittent fasting is not a problem for most people and muscle mass loss as their body will use up the muscles only in case of long starvation periods. In efficient weight loss, nutrition comes first and you need to keep active without overdoing the intense cardiovascular exercise. As long as you have enough daily protein intake your body will have what it needs for maintaining the muscles.
There is no harm in fasting short term as it doesn’t come with any muscle loss or health risks. Intermittent fasting can be done in different ways and you can pick the one that works for you. You can either fast 16 hours a day every day, fast twice a week (5:2 diet), eat 25% of your usual calorie intake every other day or do one day on and one day off (24 hours of eating nothing but drinking water or anything unsweetened). According to a recent study, fasting for 16 hours a day (8 hours of which is sleep) or eating for 8 hours helps people lose weight and decrease the risk of developing diabetes or cardiovascular illness.
Researchers in the US compared the intermittent fasting with the common low calorie diets in terms of effective weight and fat loss while maintaining muscle mass. And they found intermittent fasting to be more effective in decreasing body fat, especially around the waist. The main reason for the success of fasting is “eating less” because you’re less hungry and you have less opportunity to eat and the lowered insulin hormone. Insulin enhances storage of fat in your body and by avoiding the insulin and blood glucose spikes you’ll be less hungry and less fat will be stored. By the intermittent fasting you’ll be restoring a circadian rhythm that will help with your weight loss efforts.
You will also making a positive change in your genes that deal with immunity and the chance of inflammation and oxidative stress will be reduced. Fasting 16 hours a day is the easiest for me, as I can have a cup of coffee in the morning, then have breakfast/lunch around midday and eat when I’m hungry during the day and nothing after 8 pm. Not eating later in the evening and before bed is probably a good idea anyway for feeling better during the sleep and in the morning. When you do the intermittent fasting you’ll experience an increase in growth hormones that promote fat loss as a response to the decreased blood glucose as well as an increase in the basal metabolic rate, which is the calorie burning when you’re resting. You’ll lose a few pounds over time and the weight loss will stop when you reach your ideal weight.
