Effective self-control strategies involve much more than willpower -- ScienceDaily

They observe that in some cases the best self-control strategy involves us changing the situation to create incentives or obstacles that help us exercise self-control, such as using apps that restrict our phone usage or keeping junk food out of the house. In other cases it's more effective to change how we think about the situation -- for example, by making an if-then plan to anticipate how we'll deal with treats in the office -- so that exercising self-control becomes more appealing or easier to accomplish. Other strategies work better when someone else implements them for us. For example, our electricity company might use social norms to prompt a change in our thinking, showing us how our energy usage compares with that of our neighbors. And policymakers often use situational constraints to prompt behavior focused on the long-term. Examples range from incentives (e.g., tax rebates for eco-friendly building materials) to penalties (e.g., raising taxes on cigarettes and alcohol). Employers are increasingly using another type of situational constraint, defaults, to encourage employees to save for retirement; many are requiring people to opt out of an employer-provided retirement plan if they don't want to participate.

Only 1115 people?!

They wanted to find out if interval training might match a continuous moderate intensity workout for overall weight loss (total absolute fat mass) and reductions in percentage body fat-the percentage of fat that makes up body weight-despite taking less time to do. Interval training describes intermittent intense effort, interspersed with recovery periods. The two most common types are high intensity interval training, or HIIT for short, which includes various exercises; and sprint interval training, which includes running, jogging, speed walking, and cycling. So they searched research databases for relevant studies that directly or indirectly compared interval training with continuous moderate intensity exercise over a period of at least four weeks. The data from 41 studies involving 1115 people were combined for thematic analysis and the results data from 36 studies involving 1012 people were pooled. Both interval training and a continuous workout reduced overall weight and percentage body fat, irrespective of starting weight or gender, the findings showed.
