Scientifically proven ways to change your life in less than 30 minutes a day

Updated: Apr 5

As the seasons change, many of us are looking for a fresh start or a way to renew our health. It can seem overwhelming to take on a whole new lifestyle – better nutrition, packing lunches, cutting out sugar, regular exercise, getting to bed earlier, etc.

What I suggest as a starting point is to just choose one thing to begin with, and commit to this change for 30 days. You will be amazed at the difference you will feel. Below is a list of scientifically proven ways to change your life in less than 30 minutes a day.

My challenge to you is to choose one thing from this list, and let us know which one you have picked. Just send a quick email here, with the subject line indicating your choice. We will email back at the end of 30 days to check in with you. Remember, small things can make a huge difference! Download a chart for tracking your progress here.



You may have heard about the 7 minute workout, a quick sequence of high intensity circuit training (HICT), that has shown some impressive results. It consists of 12 high intensity exercises that use just body weight or a chair, with brief periods of recovery (10 seconds).

Health benefits have been shown to be:

  1. Reduction in body weight and body fat

  2. Improvement in metabolic markers for up to 72 hours after exercise

  3. Increased VO2max, a marker of cardiopulmonary health

  4. Reduction in insulin resistance

Pretty impressive for just 7 minutes! Here are some helpful links:

The “Sprint 8 Workout” is an 8 week exercise program designed to increase growth hormone production. An increase in growth hormone will reduce body fat, tone muscle, increase energy and improve cardiovascular endurance.

Each session lasts 20 minutes, an it is repeated 3x per week for a period of 8 weeks.

20 minutes session consists of:

  1. 3 minute warm up

  2. 8x 30 second full sprint cardiovascular activity

  3. 90 second recovery intervals between the sprints

  4. 2.5 minute cool down

In a study conducted 2011, the Sprint 8 protocol had impressive results in a group of women with an average age of 46 years, reducing body fat by 27% over 8 weeks without dieting. Other positive changes were results in the women’s lipid panels with lowered cholesterol and especially a reduction in triglyerides.

Caution: Both of these exercise programs are quite intense, especially the Sprint 8 workout. Please consult with a healthcare practitioner before beginning these exercises, especially if you are pregnant, in the first 6 months post-partum, have any joint injuries, or cardiovascular health issues.



Kirtan Kriya is a Kundalini yoga meditation that has been practiced for hundreds of years. It involves chanting the sounds Saa Taa Naa Maa along with repetitive finger movements, or mudras. The basic practice of 12 minutes per day has shown some impressive health impacts, including:

  1. Reduction in stress levels

  2. Decreases in inflammatory gene expression

  3. Dramatic increase in telomerase expression, which literally slows aging – this simple meditation practice is one of the most effective ways to do this!

  4. Better memory, and reversal of memory loss

  5. 65% improvement in depression scales – again, extremely impressive response

  6. Improved sleep quality

Full instructions for the Kirtan Kriya meditation are found here:

Being grateful and acknowledging it on a daily basis has shown to have tangible benefits. This simple task requires you to reflect on any satisfactory, positive or current blessings on a daily basis by writing in a journal. It is also highly recommended for youth and early adolescents for well-being.   Although this activity may only require about 5-10 minutes every day, studies have shown great positive effects such as the following:

  1. increase in life satisfaction

  2. optimism

  3. enhanced self-reported gratitude

  4. increased well-being

  5. significantly decreasing depressive symptoms.

How to do it:

To keep a gratitude journal, simply spend 15 minutes each evening writing down 5 things you are grateful for. Writing them down, rather than just thinking of it is extremely valuable, as the extra attention reinforces the positive changes. You will find that even after the first week, you will start to look for things in your day to be grateful for, and dramatically change your outlook on life. This practice is also excellent for children before bed, to help shift the focus of their day, and develop an attitude of gratitude.

Many studies have evaluated daily intermittent fasting, and the results are compellingly positive. Three major mechanisms by which fasting benefits your body, as it extends lifespan and protects against disease, include:

  1. Increased insulin sensitivity and mitochondrial energy efficiency – Fasting increases insulin sensitivity along with mitochondrial energy efficiency, and thereby retards aging and disease, which are typically associated with loss of insulin sensitivity and declined mitochondrial energy.

  2. Reduced oxidative stress – Fasting decreases the accumulation of oxidative radicals in the cell, and thereby prevents oxidative damage to cellular proteins, lipids, and nucleic acids associated with aging and disease.

  3. Increased capacity to resist stress, disease and aging – Fasting induces a cellular stress response (similar to that induced by exercise) in which cells up-regulate the expression of genes that increase the capacity to cope with stress and resist disease and aging.

  4. Preventing many diseases: Fasting has proven to have beneficial effects for preventing and reducing the severity of many diseases. For example; reducing the risk of cancer by having a beneficial effect on metabolism, and Alzheimer’s disease by delaying the onset or reducing the severity. It is also very beneficial for heart health by reducing LDL levels, inflammatory markers and blood sugar levels.

How to do it:

Intermittent fasting is actually quite simple. A starting point is to fast for a full 12 hours every night, including 3 hours prior to bedtime.

On a typical day, this looks like finishing your dinner by 7:00pm if you go to bed around 10:00pm, and not eating again until after 7:00am. That’s a whole lot of benefits for eating your dinner at a reasonable time and skipping the bedtime snacks!

Although many of us like to indulge on sweets and sugary treats, many studies have shown that sugar is harmful to your health. Reducing refined sugar products has long term health benefits. Try going for some blueberries or raisins after dinner instead of that chocolate bar.

As a challenge, cut out all sugar in your foods, which includes: sugar in coffee, all sweets and treats, and foods with added sugar. When you start reading ingredients listed, you’ll be surprised to find added sugar in foods such as pasta sauce, yogurt, almost all breakfast cereals, most condiments, and more!

As an added challenge, also avoid natural sweeteners such as honey, maple syrup, coconut sugar, agave and dried fruits; and limit your fruit servings to no more than 2 per day. You will notice a tremendous change in your health – energy, food cravings, weight, and even immune system, hormone balance and concentration.

A low sugar diet will:

  1. reduce cholesterol and triglyceride levels – this will reduce chances of heart disease

  2. prevents you from becoming insulin resistant – preventing obesity and diabetes

  3. allow you to increase your nutrient intake – this is because sugary foods often have no nutrient value and are full of calories

  4. allow your immune system to function optimally: sugar leaves your immune system wide open to infection!

I can’t wait to hear from you about your experience taking on one small practice for the next 30 days!
