Significantly restricting calories isn’t necessary; in fact, it’s not advisable, says Dr. Olesiak. Rather, the safest and most sustainable way to lose weight is to enjoy whole, unprocessed, high-quality foods. “These foods naturally control your hunger, increase your metabolism and promote fat burning,” he says.

Omit as many processed foods, fried foods and refined sugars as possible, adds Feit, and pay attention to portion size. “A great strategy is to use the plate method, where your plate is composed of half fruits and vegetables, a quarter of lean protein, and a quarter of fiber-filled carbohydrates,” she says.
Here are few foods that can help you maintain and reduce your weight going forward
1. Eggs
Eggs contain almost every essential vitamin (with the exception of Vitamin C), plus minerals like phosphorus, calcium and potassium. Along with being a source of complete protein, eggs are also adaptable for different tastes.
2. Vegetables
Vegetables of all kinds can assist with weight loss, says Feit. For example, cruciferous vegetables like broccoli, cauliflower, Brussels sprouts and cabbage are high in fiber and vitamins and help reduce digestive issues. Meanwhile, dark green leafy vegetables contain protein and are a good source of vitamins, minerals and fiber. And crunchy vegetables like celery and jicama are great low-calorie options for snacking.
3. Berries
Berries are high in fiber, antioxidants and vitamin C—all things that your body needs to function optimally.
4. Nuts and Seeds
Nuts and seeds have different health benefits, says Feit. All nuts are a good source of fiber, protein and healthy fat, and they help decrease hunger. Meanwhile, seeds are a great source of minerals and healthy fat. Watch your portions here, too. One serving of nuts and seeds is equivalent to a quarter cup.
