the research conducted by Donnelly et al. that was published in 1991.
69 obese women were put on an extreme 520 Calorie per diet.
These women were then divided into 4 groups
Group 1 did not exercise
Group 2 did endurance exercise for 60 minutes 4 days per week.
Group 3 did strength training 4 days per week
Group 4 did strength training AND endurance exercises 4 days per week
At the end of the 90 days research trial all 4 groups lost a mind blowing amount of bodyweight, averaging over 40 pounds of weight loss!
(Once again proving that anyone who says “It is impossible to lose weight by dramatically reducing your calories.” has absolutely NO IDEA what they are talking about!)
The interesting finding was that there were no differences between the four groups in terms of the amount of weight or body fat that was lost.
This is despite the massive amounts of exercising that group 4 was doing every single week!
This conclusion has been found over and over again in published research.
Donnelly et al. did a second trial that was published in 1993 showing that weight training could increase muscle size while women followed an 800 calorie per day diet, but it could not increase weight or fat loss.
Similar results were found by Kraemer in 1997, Bryner in 1999 and Janssen in 2002, just to name few examples.
The truth is that if you have your diet in order and are following a diet program that allows you to decrease your caloric intake it will cause you to lose weight.
Adding ‘calorie burning exercises’ does not seem to increase this weight loss, but adding strength training can preserve or even help increase the size of your muscles while you are dieting.
So if you are one of those people who spends countless hours in the gym, pushing themselves as hard as they can but are not seeing results, maybe its time to change your approach.
Eat for fat loss, workout to preserve (or even increase) the size of your muscles.
You can easily accomplish this by following the Eat Stop Eat lifestyle of Flexible Intermittent Fasting and strength training.
If you spend your energy in the right places, weight loss can be easy.
