There are many different meal replacement for weight loss alternatives but can get very confusing trying to discern which is right for you. Just because it tastes good doesn’t mean that it is healthy, not to mention that you may very well gain pounds with the wrong food choice.
Why Meal Replacements?
In order for us to lose weight, instead of the standard 3 meals, we have to adopt a new healthy fitness diet regimen that splits our portions to 6 meals a day over the course of the day.
Why 6 meals?
It takes your body an average of 3 hours to digest food. When the nutrients from food can’t be fed on any more, your body will start feeding off your water weight and muscle though fat ironically diminishes less during starvation compared to those other two sources. This is why you see people who regularly starve themselves, lose weight but are actually gaining fat.
A skinny person is worse off than a muscular person. The reason why, is that the mere existence of muscles increase metabolism to maintain your additional lean mass. Over the course of a year, you could burn an additional 10-20 pounds of fat simply because of additional lean mass.
Not only does the food preserve muscle mass, but that consistent amount of food with nutrients helps to pick up your metabolic rate as well. If you are eating small portions with a combination of lean proteins, complex carbs, and periodically essential fats, then those portions don’t go to waste and are immediately metabolized.
Meal replacements are intended for people on the go. Many people are busy with their work, family activities, and countless other responsibilities, that they don’t have the comfort of eating a meal at the table. These replacements are intended to be consumed 1-2 times a day and at the max 3 times a day. Meal replacement bars however, should not entirely be your only food source, since more nutrients can be taken in directly from real, natural, organic food.
How do I know if a nutrition bar or shake is right for me?
So you have to find the best meal replacement shakes or meal replacement bars for you. Each person, depending on their body type and body mass should have different daily consumption for calories.
The Katch-McArdle formula to figure out your daily caloric consumption, helps give you an idea of where you stand.
According to exercise physiologists William McArdle and Frank Katch, the average caloric maintenance level for men is between 2700-2900 calories daily, while for women it is between 2000-2100 calories daily. The caloric maintenance level is the amount you eat to maintain your current body composition.
To cut down fat however, you should decrease 15-20% of that caloric maintenance level:
- Men should eat 2200-2700 calories/day
- Women should eat 1400-1800 calories/day
To gain muscle is the exact opposite. You should increase your caloric intake by 15-20%:
- Men should eat 3200-4000 calories/day
- Women should eat 2200-2500 calories/day
Macronutrient Levels
Macronutrient levels consist of the right number of fats, carbs, and protein. As there are a lot of ideas on what is the right macronutrient ratio, there is no exactly correct answer. Experiment on your daily caloric intake based on your progress. If you are either cutting fat or gaining muscle, then you are on the right track, otherwise make adjustments such as dropping your daily calories or zigzagging your calories between your maintenance level and the deficit level.
One common ratio level is 50% carbs, 30% protein, and 20% fat. This might not be the right one for novices, so you may need a slight adjustment depending on the goals you want.
Next we need to figure out how many grams exist in each one of the major macronutrient areas so we can better read those nutrition labels.
1 g of carb = 4 calories
1 g of protein = 4 calories
1 g of fat = 9 calories
Notice how fats are denser? Don’t shirk fats however, especially the essential fats like poly and mono saturated.
Let’s provide an example of a male with a 2400 daily caloric intake.
Remember that we said that carbohydrates will represent 50% of the calories, 30% of protien, and 20% from fat:
2400 X .5 = 1200 calories of carbs
2400 X .3 = 720 calories of protein
2400 X .2 = 480 calories of fat
Now remember every 4 calories of carbs and protein equal 1 gram and every 9 calories of fat equals 1 gram:
1200 calories of carbs/4 = 300 grams of carbs a day
720 calories of protein/4 = 180 grams of protein a day
480 calories of fats/9 = 53 grams of fat a day
Let’s divide the daily total by 6 and that should give us a rough estimate of what this male should have each meal:
300 grams of carbs/6 = 50 grams of carbs per meal
180 grams of protein/6 = 30 grams of protein per meal
53 grams of fats/6 = 9 grams of fats per meal
So now you have a rough idea of how many calories and grams this male should be looking for in a meal replacement. Remember that calories can always be burned through exercise and nutrients are vital to maintaining your energy to workout 30-45 minutes daily.
Make sure to find bars or drinks that have little or no sugar since “healthy” meal replacements sometimes can be deceiving and may actually contain high levels of sugar and calories. The best meal replacement shakes should provide a low calorie, low sugar, high nutritional content.
If you start eating healthy, not only will you look great, you will feel great as well.
