Historically, fat storage worked well for humans. The energy was stored as small packages of molecules called fatty acids, which are released into the bloodstream for use as fuel by muscles and other organs when there was no food available, or when a predator was chasing us. Fat storage actually conferred a survival advantage in these situations. Those with a tendency to store fat were able to survive longer periods without food and had extra energy for hostile environments.
As Max explained, fat loss progress is far more "linear" than weight loss progress, with a far more steady development as opposed to a constantly fluctuating one. Putting it into context, Max notes that "our body fat percentage or lean mass does not fluctuate in the instance where we drink a glass of water, or eat a big meal and then step on the scale — only our bodyweight does this."
If you could only be a fly on the wall in our kitchen each night after dinner. We are both on My Fitness Pal planning our food for the next day and weighing and measuring our portions. It is fun to meal plan together. I make the meal plan on Sunday and my hubby prepares the majority of the food. Firemen sure do know how to cook! Maybe that is why I married him.
• Restrictiveness: The biggest psychological factor here is how restrictive your diet is. Now, just to be clear, restriction is a necessity at times – a calorie deficit, for example, is a form of restriction – and you need to understand that to be successful in changing your body composition there will be times when you’re going to need to be disciplined and restrict certain foods. But, this should only be for a short period of time and not how you should be eating all the time.
Matheny recommends a Tabata-style workout to rev up your fat-burning power. For this, you'll spend 20 seconds doing an intense exercise, like burpees, followed by 10 seconds rest. You'll repeat the sequence eight times, giving you a four-minute workout. For a quick and dirty full-body workout, repeat the sequence five times with five different exercises for a total of 20 minutes.
You have already calculated how much protein and fat you will be consuming every day. The only thing left to do is figure out how many carbs you will be eating on a daily basis. This one is simple. Whatever calories are left over after you calculate your protein and fat should be used for carbohydrates. Just take the total calories that are left over and divide by 4. This will tell you how many carbs you should eat everyday.
All of this is important to understand because while the basics of changing your body composition are simple –energy balance– each person’s personal psychology and physiology will differ. Someone who’s never exercised before and has a lot of fat to lose will have different physiological and psychological requirements than someone who stopped training for a while and gained some body fat in the interim; conversely, a lean beginner is going to be in a different place than an overweight beginner.
The prevailing formula for a long time on how much fat you’re going to burn was calories in minus calories out, based on your basal metabolic rate (BMR) and exercise efforts, explains strength and performance specialist Joel Seedman, Ph.D., owner of Advanced Human Performance in Atlanta. But with all the different biochemical reactions in the body, hormonal response, and endocrine function, there are an infinite number of factors that can affect how your body is storing and breaking down calories.
