Energy balance and healthy living -
To lose weight, the number of calories we consume must be less than the number of calories we burn. A negative energy balance over time leads to weight loss. Conversely, when we consume more calories per day than we use through physical activity, we gain weight.
Energy Balance and Obesity: Over a prolonged period, we may develop obesity. Obesity increases our risk of stroke, heart attack and, in more serious cases, can lead to organ failure.
That means we should consume energy our bodies need and also engage in a healthy level of physical activity. You can engage in minutes of moderate-intensity aerobic activity in a single session or over a few sessions by setting aside some days of the week for exercise.
Remember, it is important that you keep track and balance your energy intake calories consumed and energy output calories burned through exercising to achieve and maintain a healthy weight. A healthy year old girl, weighing at 60kg, will have to balance her regular food intake with any of these activities: an hour of badminton or fast-paced modern dance; or an hour and a half of leisurely cycling a week.
When it comes to dieting and weight loss, it is really a game of balancing the food you eat and the amount of physical activity you engage in. Most importantly, it is an ideal and healthier way to do so as well!

Related: Weight Management What Is Energy Balance? The only equation for diets is the Energy Balance Equation. What is it? across the week program for those who completed the study was During the 3rd week, the average SWA wear time was 1, In addition, food diary data were missing for three participants because they did not complete the food diary.
LOCF analyses did not differ data not shown. All other movements and eating behavior variables were not significantly associated with BM changes see Table 1. Table 1. Association between early week three and early-late change week three to week 12 movement and eating behaviors and change in body mass BM between baseline and week Hierarchical linear regression analyses were conducted to evaluate the prediction of percentage BM change from movement and eating behaviors.
Program type was controlled for and entered as a covariate in the first step of each regression model forced entry. The movement and eating behavior variables [total energy expenditure EE , light, moderate, and vigorous PA, SB, total EI, macronutrient composition, and energy density] were entered in step two using the stepwise method.
Two separate hierarchical multiple regressions were conducted to determine the unique contributions of early model one and early-late change model two in movement and eating behaviors to percentage BM change.
Model one revealed that the energy density of foods consumed and vigorous PA early in the intervention week three significantly predicted These hierarchical linear regression analyses demonstrate that higher week three vigorous PA and an increase in light, moderate, and vigorous PA were associated with greater WL.
Conversely, higher week three energy density and an increase in total EE and energy density were associated with less WL. The LOCF analyses results did not differ as shown in Supplementary Table 1.
Table 2. Hierarchical linear regression analyses predicting change in percentage BM between baseline and week 14 from week three movements and eating behaviors and from early-late change in movement and eating behaviors. CWL reported significantly greater compliance with the program compared with NWL [CWL: Refer to Section 2 of the Supplementary Materials for between group comparison of changes in BMI and body composition.
Table 3. Change in body mass BM and body mass index BMI between baseline, week 2 and week Table 4. Change in energy expenditure EE , free-living physical activity [from light to vigorous physical activity PA ], sedentary behavior SB , energy intake, and macronutrient composition between week 3 and week The main effect of group for vigorous PA was significant; CWL [3.
On average, the energy density of foods consumed was lower in CWL [1. There were no other main effects of week or group and no other week x group interactions for movement behaviors or eating behaviors.
The LOCF sample analyses as shown in Supplementary Table 2 were much the same with the addition of a significant main effect of group for percentage fat intake; CWL [ The results of this study demonstrate that early and early-late change in both free-living movement and eating behaviors are associated with weight loss following a weight loss program focused primarily on diet.
When whole sample data were analyzed, higher vigorous PA, higher percentage CHO intake, lower total EI, and lower energy density foods consumed early in the intervention week three were associated with a greater reduction in BM.
In addition, an increase in vigorous PA and a decrease in SB from early week three to late week 12 in the intervention were also associated with greater WL. Free-living movement and eating behaviors were also predictive of BM change. Consuming lower energy-dense foods and engaging in greater vigorous PA early in the intervention significantly predicted greater weight loss.
As did early-late increases in light PA, moderate PA, vigorous PA, decreases in total EE and energy density of foods consumed. When participants were categorized based on their WL response, those who experienced the most successful weight loss CWL consumed lower energy-dense foods early in the intervention and on average, they showed a significant early-late increase in vigorous PA and performed more vigorous PA on average.
Collectively, these findings demonstrate that specific behaviors that contribute to greater EE [e. The current findings showing that the amount of PA is related to WL align with previous research which found that higher PA prior to engaging in an aerobic exercise intervention 41 and greater PA levels during a WL program were associated with greater WL 42 , Research examining whether energy balance behaviors i.
The present study confirms the findings from Vaanholt et al. This suggests that change in behavior during a WL program is a more important determinant of weight loss success. To optimize WL, strategies to monitor energy balance behaviors during a weight loss intervention could identify individuals who may benefit from additional support.
Light PA and moderate PA early in the intervention were not significant predictors of WL, but an early-late change in those behaviors was predictive of WL.
Encouraging participants to replace SB with light PA and moderate PA early in the intervention could be one potential strategy to promote WL Particularly, since a decrease in SB during the intervention was associated with greater WL.
Interestingly, an early-late increase in total EE, which is heavily influenced by RMR which, in turn, is dependent on BM, was predictive of poorer WL outcomes in the current study. This finding appears counter-intuitive at first, but a probable explanation is that the total EE algorithm within the SWA software was influenced by the individuals who gained weight.
BM is part of the SWA algorithm for estimating EE and an increase in BM with an associated increase in resting metabolic rate would result in an increase in total EE with no change in PA. Another possible explanation is that increased EE was driving an increase in EI, as proposed previously 46 , 47 , resulting in poorer WL.
Individuals who experienced the most WL CWL had significant differences in PA behavior profiles compared with those who experienced less WL NWL. The CWL group significantly increased their vigorous PA whereas the NWL group showed a slight reduction.
Furthermore, those who lost more weight performed more vigorous PA on average. Previous research has highlighted the role of vigorous PA in weight management However, the increase in vigorous PA could be large enough to positively impact other health outcomes. A recent review concluded low-volume high-intensity interval training protocols, with a similar amount of vigorous PA to the increase observed in the CWL group, has no effect on body fat or BM, a tendency to improve FFM although not statistically significant and favorable effects on various health outcomes, such as cardiorespiratory fitness The observed increase in vigorous PA may reflect concerted efforts to increase purposeful structured exercise rather than incidental PA and potentially resulted in greater compliance with the WL diet as has been previously reported Indeed, the CWL group self-reported significantly higher compliance with the program.
The consumption of lower energy-dense foods and lower total EI early in the intervention were associated with greater WL. Furthermore, consumption of lower energy-dense foods early in the intervention and an early-late decrease in energy-dense foods was predictive of successful WL.
These findings are in line with previous research concluding that the consumption of a diet lower in energy-dense foods may be an effective strategy for managing body weight Those who achieved clinically significant WL also exhibited different eating behavior to those who did not.
Early in the intervention and on average, the CWL group consumed lower energy-dense foods compared with the NWL group. This supports previous findings demonstrating consumption of a low energy-dense diet leads to weight loss through improved appetite control and reduced EI There was also a trend toward the main effect of week and group for percentage fat intake such that percentage fat intake was higher in the NWL group and there was an early-late increase in the percentage fat intake but not absolute fat intake.
The types of fat participants consumed were not measured, therefore it is not possible to comment on the quality of fats consumed by participants in this study This study supports previous research reporting that early WL is an important marker of program success and long-term WL outcomes This provides further support for the use of early non-response to WL programs as a marker for identifying individuals who could benefit from additional support.
Unick et al. Additional research is needed to explore the optimal time point to intervene, the threshold for identifying those in need of additional support, and the type of intervention that is most effective for boosting WL in early non-responders.
In the present study, strategies early in the intervention to improve compliance, promote PA particularly vigorous PA , and reduce the consumption of energy dense foods may have promoted greater WL in those with poorer WL outcomes. Assuming EI and EE remained the same, that would give an energy deficit of ~, kcal for the CWL and ~85, kcal for the NWL over the study.
These calculations highlight the well-documented issue of underreporting inherent with self-reported dietary intake, particularly in people with obesity 56 , It is acknowledged that the calculations are not accurate 58 ; however, the 7, kcal rule provides an indication of the energy deficit required to produce the observed weight losses vs.
the energy deficit calculated from the EI and EE data. These considerations highlight the potential problems with self-report dietary variables as the potential predictors of weight outcomes. This has implications for the combined predictor and the group comparisons presented above.
Interestingly, it also implies that those who are more successful at WL are able to more accurately assess their true EI over time. These considerations are part of an on-going analysis of dietary misreporting as a predictor of successful WL.
There are several limitations inherent in this study that should be acknowledged. First, due to the restrictions around participant recruitment, PA and EI were not fully captured at baseline and some adaptations may already have occurred in the first 2 weeks of the intervention. Changes identified between early and late measurement periods may have reflected a regression back to baseline, for example, the increase in percentage fat intake, limiting the interpretability of these findings.
However, early and early-late changes in PA and EI were still predictive of WL success. Second, while the data suggests adherence to the WL program may play a role in WL outcomes, there are limitations with this measure. There is no accepted or feasible method of measuring adherence to WL programs In this study, adherence was self-reported and may have been confounded by participants knowing whether they lost weight each week.
PA promotion was a component of the WL programs and accelerometer-based measures of free-living PA were positively correlated with adherence data not presented supporting the validity of the adherence measure.
Third, WL was induced using two different WL programs commercial and self-led , but because there were no specific research questions pertaining to program type, WL data were analyzed with both WL program groups combined and program type was controlled for in all the analyses.
However, the two WL programs were inherently different. It is therefore difficult to disentangle whether reduced energy density was a predictor of WL success, given the group that was placed on the low energy dense diet lost the most weight 29 , or whether it was due to the face-to-face support that group received, or a combination of both.
Fourth, although it is an accepted and widely used energy density calculation, the Wrieden method did not account for the calories consumed in drinks other than milk. Fifth, the stage of the menstrual cycle was not controlled for and therefore a confounding effect on energy intake cannot be ruled out Finally, to overcome the attrition in this study, which is common in WL interventions 60 , missing data was imputed using the last observation carried forwards method.
This method has previously been implemented in WL trials 61 and the limitations of this approach have previously been acknowledged Early and early-late change in free-living movement and eating behaviors during a week WL program are predictors of WL.
Interventions targeting these behaviors may increase the effectiveness of WL programs. Additional research is needed to explore the threshold for identifying those in need of additional support, the optimal time point to intervene, and the type of intervention that is most effective for boosting WL in those in need of additional support.

The energy that leaves our body is a bit more complicated: it is a result of our basal metabolism which gets really complicated and any sort of physical activity we do that requires energy to accomplish.
Energy that leaves our body is usually described as our Total Daily Energy Expenditure, or TDEE. In most people this TDEE is comprised of the following components:.
As mentioned above, when there is more energy going in than going out, you are in a state of positive energy balance. Being in a state of positive energy balance can be affected by both having too high of an intake or too low of an output, or a combination of both.
It is important to note that the relative amounts matter more than the absolute amounts. A positive energy surplus can be created by creating a disparity between eating more calories than expended, which may come from very high calorie intake or very low energy expenditure.
Like a positive energy balance, negative energy balance is created when the energy mismatch goes the opposite direction: more energy is expended than is going in.
The energy that the body utilizes at this point is stored energy in the form of stored carbohydrates, stored fats, or stored proteins. Perfect energy balance occurs when the energy coming in and the energy expended are perfectly matched. In reality, this is very difficult to do over very short time frames e.
being in perfect balance in a given day , but is relatively easy to accomplish over periods of weeks or months. Therefore, many people stay weight stable for years at a time.
Perhaps the most effective way to assess energy balance is to track body weight over extended periods of time think weeks or months, not days. Body weight can fluctuate substantially during a given day or week due to hydration status, glycogen status, and other variables, but the average weight over several weeks or months is an excellent indicator of the state of energy balance a person is in.
If body weight is increasing over the span of weeks or months, that person is in positive energy balance. Conversely, if body weight is increasing over the span of weeks or months, that person is in negative energy balance. There are many ways to measure energy balance, some being far more intricate and complicated than others.
There are laboratory measurements such as metabolic chambers and doubly labeled water which can be very accurate but are impractical for almost all settings except in scientific studies. Energy balance and metabolism are linked, but their relationship is not as quite forward as most people might think.
In one sense, metabolism has a direct influence over energy balance. If your TDEE is either very high or very low, the likelihood of you being in perfect energy balance is very unlikely.
For example, athletes who expend 7,, calories per day during peak training seasons often find it hard to stay in energy balance as eating 10, calories a day can be very difficult. Conversely, individuals who are very sedentary and only expend a total of ~1, calories per day often find themselves in a state of positive energy balance and keeping intake that low consistently can be very difficult.
In another sense, energy balance can affect metabolism as well. But in reality, the state of energy balances a person is in does affect their TDEE quite a bit, but not really their resting metabolic rate. For example, if an individual is in a state of positive energy balance their total expenditure goes up to try and balance that out.
However, this increased expenditure comes almost entirely from increasing their non-exercise activity. The opposite is also true. In the context of a negative energy balance, energy expenditure goes down to try and balance it out, with most of that drop coming from a reduction in physical activity.

The more muscle tissue you have, the more kilojoules you can burn. Regular physical activity helps you manage your weight and maintain good health — it can even reduce your risk of chronic diseases. To actively lose weight, aim to do 60 — 90 minutes moderate-intensity physical activity most days of the week.
Start small and gradually work your way up. Remember, weight you lose gradually is more likely to stay off than weight you lose through crash diets. Find out more about physical activity.
Reducing the amount of kilojoules we eat and drink every day, or doing more exercise every day, even by small amounts, can all add up and make a difference.

Carbohydrate is the most important source of energy for the body because it is the main fuel for both your muscles and brain. Sources of carbohydrates include starchy foods, like bread, rice, potatoes, pasta, pulses and breakfast cereals. Choose higher fibre and wholegrain versions of these where possible.
Higher intakes of fibre have been linked with a lower risk of getting diseases such as colorectal cancer, type 2 diabetes and heart disease. We also get energy from protein and fat and these form an important part of our diet too but we don't need to eat as much of these as carbohydrates. The Eatwell Guide shows the ideal make-up of a healthy, balanced diet.
You can find out more about the Eatwell Guide on our page on a healthy, balanced diet. Different people need different amounts of energy. The amount needed to maintain a healthy weight depends on your basal metabolic rate BMR , which is the minimum amount of energy your body uses to maintain basic bodily functions like breathing and your heartbeat.
BMR varies from person to person depending on your age, body size, gender and genes. But we also use energy to digest food and for physical activity. Some activities use more energy than others.
For example, running will use more energy than a gentle walk and rowing will use more energy than typing! The more active you are, the more energy your body uses up. Your weight depends on the balance between how much energy you consume from food and drinks, and the total amount of energy that is used by your body.
When you eat or drink more energy than you use, you put on weight; if you consume less energy from your diet than you use, you lose weight; but if you eat and drink the same amount of energy as you use up, you are in energy balance and your weight remains the same.
