Alpha Coach Evolve helps you to take control of your nutrition through a simplified nutrition tracking system that prompts you to adapt to your metabolism rate week over week.

Its coaching algorithm works on the premise that any change in your body weight over time is directly linked to the difference in calories you consume and the calories you expend through your daily activities including physical exercise.

In other words, the science in this App is based on simple arithmetic:

The calories you consume minus the calories you expend will account for the calories associated with the change in your body weight over time.

The heart of the Alpha Coach algorithm is calculating the calories you expend in a day, which is what is called our metabolism.

Metabolism (calories expended) = Calories associated with a change in body weight over time minus calories consumed (through food intake).

The power of the algorithm lies in its capability to make weekly adjustments in your macro program based on your food logs and body weight logs. The app prompts you to adhere to your set goals depending on your fitness goals of losing or gaining weight. In doing so, it helps you get there in the optimum time possible.

This may sound simple, but giving you the right calorie recommendation based on your metabolism rate is a complex process. We have to account for daily fluctuations in your body weight due to water retention and inaccuracies in your food/weight logs.

Once you fill up an initial questionnaire, we use a modified version of the Harris-Benedict equation to calculate your total daily energy expenditure, known as BMR (or Basal Metabolic Rate) corresponding to your body type (body-fat percentage), age, height, weight, activity level, and exercise intensity.

We start off with such a theoretical estimate. However, as you start logging your food and body weight week over week, the system adapts to you in a personalized

way. It soon starts giving you the most accurate prompts to guide you toward your personal fitness goal.

The system will calibrate your macro program every Monday to give you the best possible plan to reach your goal within a predicted timeline.

You are familiar with the calories burnt values you see on your fitness tracker, treadmills, etc. The best trackers throw these numbers with accuracy levels as low as 40 percent. It is technically impossible to accurately predict how many calories you have burnt based on your heart rate or the time you have spent on physical activity. These are, however, good yardsticks to measure progress, though the length of the yardstick may not be a standardized one. But, when you start giving calorie recommendations based on these numbers, things start going wrong.

The most accurate way to predict your metabolism trend is to clearly track your calorie intake and your body-weight changes. The more accurate your food logging is, the more accurate will be your calorie prompts on the App toward your fitness goal.

However, we know that the process of logging the food you take and weighing yourself daily is not practical for many. This is where our adaptive intelligence kicks in.

Most people struggle with regular food logging, let alone logging with a level of accuracy. Therefore, instead of true calorie intakes, we look at calorie trends based on the days the users log their food accurately. The more regular you are in doing your food logs, the more accu- rate will be the recommendations you receive.

We also know that you don’t eat exactly the same every day. There will be days you go partying and there will be days your food intake will be lower than your need due to one reason or the other. The calorie intake trend prediction algorithm looks at the trend in which you are consuming calories over a few weeks, rather than the calorie consumption on a particular day.

Checking scale weight every day can be an unpleasant experience for many folks - Our algorithm takes care of daily fluctuations in body weight due to menstrual cycles, bloating, and so on.

It is not uncommon for you to worry about the scale weight. Scale weight may fluctuate after a big meal or when you are constipated or bloated on a menstrual cycle. Instead of relying on scale weight, we look at the trend weight which is more of a moving average of your bodyweight over weeks. This is more of an accurate rep- resentation of how your body weight is moving week over week. This trend prediction mechanism allows us to give accurate recommendations for you week over week.

Alpha Coach plans your macro-splits based on your eating patterns and your training levels. The splits are built taking into consideration practicality. For example, for a vegan, a super high protein diet without eating enough carbohydrates become difficult.

Protein requirements go up on a fat-loss program, espe- cially for those at intermediate/advanced levels of train- ing to maintain muscle mass.

However, for the ease of users and keeping practicality in mind, we recommend users hit their calorie and pro- tein numbers and not worry much over carbohydrate/fat split.

We would alert the users if the sugar intake is too high or if the fat intake is too low.

One thing, we cannot handle fully is the partial logging of food.

We take into account only food logs where you have clicked ‘Finish Day’, confirming that your food log is com- plete. However, if you are to play around, partially log your meals, click ‘finish day’, and generate an alpha score. You will likely get less accurate recommendations because you are bluffing yourself.

Like any real human coach, the Alpha coach algorithm will give you recommendations based on how truthful you are to the App.

One thing the App cannot detect is your feeding the system with incorrect data.

If you are struggling to manage your body weight de- spite trying everything with your diet, understanding your metabolism and how your metabolism trend is moving week over week and eating according to your metabolism could solve this problem.

The only way to figure this out is to log your food accu- rately and log your body weight regularly.

If you can spend 3 mins a day, logging food and body weight, Alpha Coach will take care of the rest.
