Is it possible to lose 20 kgs in 4 months with Zumba and dieting?
Yes it is possible but not very sure you will loose exact 20 kgs. You can loose more than 20 kgs or it can happen you can loose then than 20 kgs. First of all very pleased to hear that you also do Zumba as I have been doing Zumba for last 3 years and it has really worked for me. Try to maintain a proper diet. Do follow the below diet as mentioned.
Early Morning Honey, lemon juice, and warm water
Breakfast -Oatmeal with strawberries or 1 bowl papaya with 3–4 egg whites
Pre-Lunch Green tea
Lunch- Cabbage soup and 100g low-fat yogurt
Post-Lunch 1 peach or 1 orange
Evening Snack Green tea and 2 digestive biscuits
Post Zumba - 1 Cucumber
Dinner 1 bowl of boiled lentils with stir fried French beans, capsicum, and peas with a dash of chopped garlic and 2 pcs of roasted chicken.
For atleaast a month try this diet. If you face any difficulty do come back to me.
