The available evidence shows that moderate carb restriction is effective in treating any female hormonal problems that might be driving weight gain. In this study of women with PCOS, for example, 30% of calories from carbs worked better than 55% of calories. On the other hand, an extremely low-carb diet is not necessarily the answer either: especially for women, extreme carb restriction can cause problems of its own, including hormonal dysfunction, amenorrhea (loss of normal periods), and infertility. Sweet potatoes are not the enemy! You can eat 1-2 starchy tubers (potatoes or sweet potatoes) every day and still be well under 30% of calories from carbs.
For strength training, working with a trainer for a session or two can be helpful to acquaint yourself with dumbbells and the types of exercises you can do, but you don’t even need to use extra weight. One of my favorite weight loss tips for women is to add bodyweight exercises like push-ups and lunges to your workouts; they’re super effective and you can do them anywhere. Pilates and more vigorous yoga classes are a great option, too.
Most women will need to eat and drink fewer calories and get the right amount of healthy foods to lose weight. Increasing exercise or physical activity may help with weight loss, but choosing healthy foods (lean protein, whole grains, vegetables, and fruits) is what works best for many people to achieve a healthy weight.1 Combining healthy eating with increased physical activity is best. Talk to your doctor or nurse before starting any weight-loss program. He or she can work with you to find the best way for you to lose weight.
