Lift Free And Diet Hard with Andrew Coates
HealthHealth & FitnessFitness

Martin MacDonald is one of my longest sought after guests and we finally got to sit down and record a podcast. And it’s worth the wait.


You’ve heard the narratives about:


Faster weight loss causes greater weight regain later

Slower fat loss leads to better long term success

Faster weight loss contributes to eating disorders

Faster weight loss causes metabolic damage

More aggressive dieting automatically causes greater muscle loss

Deeper calorie deficits cause more hunger


Well, what if we told you none of this is true and that there’s 50 years of research and evidence to support aggressive dieting as a superior approach for most people.


Martin breaks down this evidence in a thorough masterclass on aggressive dieting. This includes:


The research and practice debunking all of the above long standing beliefs

Parameters on the appropriate rate of and approach to aggressive dieting

The advantages of taking a structured aggressive approach to dieting for fat loss

How an aggressive dieting approach can blunt hunger

Why shorter more aggressive periods of dieting can lead to better outcomes for most people

The handful of categories of people aggressive dieting isn’t suitable for

Nuanced thoughts comparing GLP-1 medications to aggressive dieting

What Martin means by granting “Unconditional permission to eat”

Changing beliefs with evidence across Martin’s career

Does anything change here with menopausal/peri-menopausal women

The importance of resistance training with aggressive dieting

And much more
