If you are struggling to drop body fat, or find you have reached a sticking point consider the following...

You are eating carbs at the wrong time...

For most people any time is the wrong time. I would recommend lots of veggies and some post workout rice, pasta or potatoes. And  once per week on your cheat day.

Otherwise limit carb consumption to post workout and night time. You don’t want to load up on starchy carbs during the day to avoid the post carb crash and stay alert throught the day. Save for them for your evening meal so you can improve serotonin production and enhance your bodys ability to recover.

You’re Not Eating Enough Protein

Generally women are more guilty of this but guys can make this mistake as well.
Most resources would recommend around 100 grams of protein per day, if not a gram per pound, so for a 9 stone woman for example, that would be 126g protein per day.

People who eat a sufficient amount of protein usually end up having an easier time getting lean than those who don’t.

Your liver is over worked

 Everything that goes into your body has to be processed by the liver.
That means piece of chicken, tomato, biscuit, pringle, alcoholic drink, juice or glass of water that enters the body puts a stress on the liver.   If you are constantly eating and drinking less than optimally and overstressing the liver, fat loss will become that bit more difficult. Reduce or cut out alcohol, eat more organic, grass fed (as opposed to grain fed) meats, and try periods of intermittent fasting to reduce the stress on your liver and fat loss should become easier. For a guide to Intermittent Fasting, check out this awesome link.

You’re eating too much fruit and/ or nuts.

Huh? What about my 5 a day?? Fruit is great, I love it, but fruit is sugar, and while its great in limited amounts, fructose (a sugar found in fruit) is sugar and excess amounts can lead to fat gain.
Fructose can only be processed by the liver and once liver glycogen stores are full the excess gets converted to triglycerides and stored as body-fat. If you want to get lean cut fruit out for a while or limit it to one or two servings per day. Make sure you maintain your 5 a day habit (5 is really a bare minimum, I personally would aim for double figures, its easier than you think!) by increasing your veggie intake to ensure you get all the necessary nutrients these provide.

You are doing too much cardio...

Typical cardio training sessions are pretty much useless for fat loss.
Excessive amounts of cardio (anything above about 15 mins of steady state cardio) leads to an increase of cortisol which in turn leads to more abdominal fat.
 And no-one should ever find themselves on an cross trainer. Ever.

Best use of a cross trainer ever...

You’re not getting enough sleep.

When you’re short on sleep your insulin sensitivity decreases and your cortisol goes up. Both things lead to less than optimal fat loss.
You also miss out on the critically important Growth Hormone boost that comes each night during deep sleep. If you want to lose more fat you have to get more sleep. Most people ignore this factor when it comes to fat loss, unfortunately this just might be the most important factor of all of the above.
