For 3 yrs drank coffee all day and only ate dinner. Eating again gained 40 lbs in 5 mos. How do I lose weight on one meal a day?

Here are a few tips to help you lose weight on a one-meal-a-day diet:

1. Choose healthy foods for your meal.

- Fill up on nutrient-rich foods such as fruits, vegetables, whole grains, and lean proteins

2. Make your meal balanced.

- Include a source of protein, carbohydrates, and healthy fats in each meal.

3. Eat slowly and mindfully.

- Take your time eating and enjoy each bite. Avoid distractions like TV or your phone.

4. Stay hydrated.

- Drink plenty of water throughout the day.

5. Get regular exercise.

- Exercise can help you burn calories and build muscle mass, which can boost your metabolism.

6. Get enough sleep.

- When you're sleep-deprived, your body produces more of the stress hormone cortisol, which can lead to weight gain.

7. Be patient.

- Losing weight takes time. Don't get discouraged if you don't see results immediately. Just keep at it and you will eventually reach your goals.

Remember that losing weight should be a gradual process. Trying to lose too much weight too quickly can be harmful to your health. Aim to lose 1-2 pounds per week, and talk to your doctor if you have any concerns about your weight loss journey.
