Using Carbs & Fat Loss

A huge topic is insulin and carbohydrates. We've seen carbohydrates get a very bad and unjustified reputation when it comes to fat loss.

You can use carbohydrates and feel keeping them as high as possible WHILST allowing for fat loss to occur is only a positive thing. Here are some of the many reasons why this is -

1. Keeping your carb intake higher will often mean your muscles are fuller which improves aesthetics 
2. Keeping your carb intake higher will help sustain metabolic output 
3. Keeping your carb intake higher should help improve performance in the gym 

The theory that carbs are "evil" where fat loss is concerned is down to the fact that they illicit an insulin response. However, a rise in insulin levels doesn't necessarily mean that lipolysis will grind to a halt forever!!! It's not so much a case of "on and off" - a sliding scale would be a more accurate description. 

The idea that insulin shuts fat loss down is based on the idea that it binds to receptors on fat cells. However, in trained individuals who are pushing the boundaries in the gym and are following a nutritious diet the reality is insulin will also be binding to muscle and liver cells to aid in the uptake of amino acids and glucose. 

Remember certain proteins will also illicit an insulinogenic response (not necessarily on par with carbs) so to say if you elevate insulin you can't drop body fat is kind of crazy right? 

Instead to maximize fat loss it comes down to optimizing insulin sensitivity which can be done through diet and training. I've had multiple clients who feel they are carb sensitive come to me and end up dropping body fat and gaining lean tissue after I increase their carbohydrate intake. 

Here are some key points to optimizing insulin sensitivity in relation to diet - 

1. Focus on including adequate fiber and essential fatty acids to help blunt the insulin response of a meal (NO, insulin isn't necessarily bad but we want to help mediate this and not create aggressive spikes) 

2. Eat every 2-4 hours throughout the day. This means that your calorie intake per meal will be less than if you were eating the same calories across maybe 2-3 meals. As a result less insulin is secreted per meal and you're going to retain balance easier.

3. Pick high quality carbohydrate sources which won't contribute to a high GL (glycemic load) unless you need this. I'd also recommend limiting fructose to around 20% of your total intake of carbs during the day.

Certainly some people will be more tolerant of carbohydrates than others, however my point is that in my experience people are overly cautious of carbohydrates and tend to avoid them too much to their own detriment.
