For our research, we concealed the true goal of our analysis (looking into weight loss response to exercise) from the individuals, and used bogus goals instead (cognitive performance and cardiovascular fitness improvement). We also excluded women who designed to lose weight from the study because there is an increased risk that they would limit their diet. In two training studies, over four and eight weeks, women aged 18 to 32 attended circuit-training classes three times a week.
We documented the women’s bodyweight, muscle and excess fat mass in the beginning and at the end of the study. We also took blood samples so that we could measure appetite hormones (insulin, leptin, amylin, ghrelin and PYY), as they can alter food and appetite consumption. Results showed that neither lean nor obese women lost weight, including the 34 finishers of the four-week training programme, and the 36 finishers of the eight-week exercise programme.

Although, trim women did gain muscle mass. When we looked at individual weight responses to the exercise programs, we pointed out that the levels of appetite human hormones leptin and amylin helped clarify why some individuals gained or lost weight by the end of the analysis. Changes in appetite hormones as a result of exercise make it much harder for many people to lose weight than for others.
In other words, the power they burned through the exercise course was replaced in their diet. Their body was effectively defending against weight reduction, regardless of whether these were low fat or obese. This somewhat frustrating outcome will not imply that exercise is not good for people. There is absolutely no question that exercise has health benefits on many levels, whether it is for prevention of lifestyle diseases, such as type 2 diabetes or cardiovascular disease, or mental health issues, like unhappiness.
But we need to consider our ancestors advanced to endure over millennia in conditions where food was scarce, so our anatomies are better modified to defending against weight reduction than defending against putting on weight. Our bodies change and try to preserve our body weight if we take up exercise, but they don’t adapt to help us lose weight if we gain a few pounds.
However, exercise can help to control weight in indirect ways. It could help us develop more self-control and not surrender to food temptations easily. We are able to also transfer some skills learned from regularly taking part in exercise, such as time management and overcoming periods of low motivation, to other behaviours, such as eating.
People need to focus on their diet if they want to achieve weight reduction. Merging a healthy diet – such as steering clear of sugary and processed food items, eating plenty of veg and other high-fibre foods, avoiding snacking and having regular foods – with exercise will surely produce results.
