Online Fitness plans are web-based fitness programs designed to help participants lose weight. These may include assistance in the areas necessary for weight loss such as goal setting, progress tracking, meal and workout planning and personal support from personal trainers or fitness coaches.
Online weight loss plans are usually interactive programs that provide the user with diet information, workout routines, meal planning, goal tracking, and feedback. Web-based programs usually attempt to incorporate all of these areas and customize them for a particular user. The user will usually fill out a questionnaire before proceeding. The questionnaire will contain information such as current eating patterns, fitness levels and goals.
A personalized meal plan and workout program are usually created for the user. One feature of these programs is the use of online tools to track improvements, and to log workout and diet information. The idea behind these tracking tools is that by tracking fitness, a person can make more progress by aiming for and meeting regular fitness goals. Programs range in price from the very basic, to highly customized programs created by celebrity fitness experts. There are also free web-based programs. While they usually provide access to online tools, they may not provide any customized plans.
Online weight loss plans usually contain some of these elements:
Weekly shopping lists
Workout routines and meal plans
Regular support from a fitness coach or personal trainer (some with round-the-clock support)
Regular tracking of progress
Workout videos
Some type of online workout calendar or journal
Impact
In a year-long study published in the Journal of the American Medical Association, participants of an online weight loss plan lost more than twice the weight of participants who took part in a more traditional program. It has been shown that people who have used online weight loss plans for 18 months were able to maintain significant weight loss. Many studies now show that Internet programs are viable tools to help people maintain weight loss over the long term. In one study, a group of 250 people lost weight over a six-month period and maintained weight loss for 12 months afterwards using an online weight loss plan.The low cost combined with the lack of need for face-to-face meetings with a nutritionist or personal trainer make Internet programs easy to maintain long-term loss. The requirement of constantly updating weight and other measurements helps to hold the user accountable as well. This could help people maintain weight loss over a long period. Many studies even show that participants that logged in to their online programs more also experienced, on average, more weight loss. There has been an upsurge of companies specifically dealing with only online weight loss. There has recently been research into the effectiveness of web-based weight loss programs in primary care settings.A fitness function is a particular type of objective function that is used to summarise, as a single figure of merit, how close a given design solution is to achieving the set aims.
In particular, in the fields of genetic programming and genetic algorithms, each design solution is represented as a string of numbers (referred to as a chromosome). After each round of testing, or simulation, the idea is to delete the 'n' worst design solutions, and to breed 'n' new ones from the best design solutions. Each design solution, therefore, needs to be awarded a figure of merit, to indicate how close it came to meeting the overall specification, and this is generated by applying the fitness function to the test, or simulation, results obtained from that solution.
The reason that genetic algorithms cannot be considered to be a lazy way of performing design work is precisely because of the effort involved in designing a workable fitness function. Even though it is no longer the human designer, but the computer, that comes up with the final design, it is the human designer who has to design the fitness function. If this is designed badly, the algorithm will either converge on an inappropriate solution, or will have difficulty converging at all.
Moreover, the fitness function must not only correlate closely with the designer's goal, it must also be computed quickly. Speed of execution is very important, as a typical genetic algorithm must be iterated many times in order to produce a usable result for a non-trivial problem.
Fitness approximation may be appropriate, especially in the following cases:
Fitness computation time of a single solution is extremely high
Precise model for fitness computation is missing
The fitness function is uncertain or noisy.
Two main classes of fitness functions exist: one where the fitness function does not change, as in optimizing a fixed function or testing with a fixed set of test cases; and one where the fitness function is mutable, as in niche differentiation or co-evolving the set of test cases.
Another way of looking at fitness functions is in terms of a fitness landscape, which shows the fitness for each possible chromosome.
Definition of the fitness function is not straightforward in many cases and often is performed iteratively if the fittest solutions produced by GA are not what is desired. In some cases, it is very hard or impossible to come up even with a guess of what fitness function definition might be. Interactive genetic algorithms address this difficulty by outsourcing evaluation to external agents.
