A 3-month program with diet changes, strength training, and intense workouts helped older adults with obesity and type 2 diabetes lose fat and keep or gain muscle — and those benefits lasted for at...

For obese women between 40 and 60 years old, losing visceral fat over 16 weeks through a reduced-calorie diet happens at the same rate whether or not they do resistance training. Adding resistance training does not lead to more visceral fat loss than dieting alone.

For women who aren't very overweight, adding aerobic exercise to a calorie-restricted diet doesn't help them lose more fat than just eating less — as long as both groups burn the same total calories over 8 weeks.

Adding high-intensity interval training to a very low-carb diet doesn't stop the muscle loss that happens when people with excess body fat eat very few carbs for 12 weeks.

In obese women aged 40–60, combining a calorie-restricted diet with resistance training changes where body fat is lost, shifting the greatest reduction from the lower abdomen to the upper abdomen. This shift does not occur with diet alone, suggesting resistance training influences the location of fat loss regardless of how much total fat is lost.

In obese adults with type 2 diabetes, losing weight through diet and exercise improves blood sugar control, reduces body fat, and increases aerobic fitness, and these improvements continue for at least one year after the program ends.
